4 CFPB DATA POINT: CHECKING ACCOUNT OVERDRAFT

1. Introduction

Users of checking accounts sometimes engage in debit transactions in amounts that exceed their 

accounts’ balances. An overdraft occurs if their financial institution chooses to cover such a 

transaction. Financial institutions will typically charge a fee for an overdraft, although particular 

overdrafts may avoid a fee depending on the particular circumstances of the transaction and the 

financial institution’s policies. Overdraft fees generally do not vary by the size of the transaction 

or the amount by which the consumer’s account balance falls below zero.1

In this Data Point we present the results of several analyses of consumers’ experiences with 

overdrafts at a number of large banks. In many instances we break down our results by an 

account holder’s status under Regulation E requirements (also known as “opt-in status”). This 

refers to the 2009 Federal Reserve Board amendment to Regulation E, subsequently recodified 

by the CFPB, that generally requires financial institutions to obtain affirmative consent from

account holders (“opt-in”) to be charged fees for overdraft coverage on automated teller 

machine (ATM) and non-recurring point of sale (POS) debit card transactions. This has the 

practical effect of institutions being less likely to authorize overdrafts on these types of 

transactions for account holders who have not opted in. This change became effective for new 

accounts on July 1, 2010, and for existing accounts on August 15, 2010.

 

1 Some institutions have de minimis policies in which non-sufficient funds (NSF) and overdraft transactions are not 

assessed fees if the transaction amount or the amount by which the account balance falls below zero dollars is less 

than a specified threshold. Some institutions also have caps on the number of overdraft fees and NSF fees that will 

be assessed in a single day. Institutions may also empower employees to waive fees manually on individual 

judgment or in accordance with institutional guidelines. Additionally, an observed minority of institutions tier NSF 

and overdraft fees by transaction amount. However, in general, NSF and overdraft fees are fixed for transactions 

that do not trigger de minimis policies.
5 CFPB DATA POINT: CHECKING ACCOUNT OVERDRAFT

Key findings of this report with respect to the banks studied include:

 Overdraft and non-sufficient funds (NSF) fees constitute the majority of the total 

checking account fees that consumers incur. For opted-in consumers, overdraft and NSF 

fees account for about 75 percent of their total checking account fees and average over 

$250 per year.

 Most overdraft fees are paid by a small fraction of bank customers: eight percent of 

customers incur nearly 75 percent of all overdraft fees.

 The propensity to overdraft generally declines with account holder age, with 10.7 percent

of the 18-25 age group having more than 10 overdrafts per year, but only 2.8 percent of 

the 62 and over age group falling into this category. 

 The number of overdraft transactions and fees varies substantially with opt-in status. 

Opted-in accounts are three times as likely to have more than 10 overdrafts per year as 

accounts that are not opted in. Opted-in accounts have seven times as many overdrafts 

that result in fees as accounts that are not opted in. Disentangling the causal nature of 

the relationship between opt-in status and overdrafting would require further analysis.

 Transactions that lead to overdrafts are often quite small. In the case of debit card 

transactions, the median amount that leads to an overdraft fee is $24 and the median 

amount of a transaction that leads to an overdraft fee for all types of debits is $50.

 Most consumers who overdraft bring their accounts positive quickly, with more than half 

becoming positive within three days and 76 percent within one week.

The Bureau’s analysis of the overdraft data is ongoing as the Bureau seeks to gain further insight 

into some of the questions posed by the white paper the Bureau issued last year.2 Future Data 

Points or other Bureau publications will report on further findings.

 

2 CFPB Study of Overdraft Programs: A White Paper of Initial Data Findings (June 2013).
6 CFPB DATA POINT: CHECKING ACCOUNT OVERDRAFT

2.Data

In its supervisory role, the CFPB has obtained a representative sample of account-level and

transaction-level checking account histories from each of several large banks. These are large 

banks covered by the CFPB’s supervisory authority and do not include credit unions, thrifts, or 

banks with total assets under $10 billion. These same large banks also provided the institutionlevel data used in the CFPB Study of Overdraft Programs: A White Paper of Initial Data 

Findings (June 2013), hereafter referred to as the “White Paper.” Neither the account-level nor 

the transaction-level data contain any directly-identifying personal information.3

The transaction histories contain every transaction that a random sample of the banks’ account 

holders undertook during the 18-month period spanning January 2011 through June 2012. Each 

entry generally includes a transaction’s dollar amount, type, posting date, and posting order; the 

account ledger balance at the end of the previous day’s processing; and a flag indicating whether 

the transaction resulted in an overdraft or was returned for non-sufficient funds (NSF) and, if 

so, whether a fee was charged.4 The transaction histories provide a more detailed picture of 

overdraft activity than do the aggregated statistics that formed the basis of the White Paper, and

have allowed us to apply a uniform method across banks to measuring the various statistics.

 

3 Because the data used in this analysis are Confidential Supervisory Information, this paper only presents results 

that are aggregated and does not identify specific institutions. 

4 For many of the banks, we do not have data on debit card or ATM transactions that were declined at the point of 

sale; we do not include these declined transactions in calculating total transactions, although we do include 

returned checks and returned ACH debits. If an item (such as a check or ACH debit) was presented more than once, 

each occurrence is counted as a separate transaction.
7 CFPB DATA POINT: CHECKING ACCOUNT OVERDRAFT

The account-level data are monthly account summaries for the 30 months spanning January 

2010 through June 2012.5 For each month and each account in the sample, they include, among 

other information, summary information about transactions such as total deposits (volume),

end-of-month balances, and indicators for account configurations such as the Regulation E optin status of the account. In addition, the banks provided the year of birth for the primary holder 

of each account.

Detailed account and transaction data allow us to narrow our analysis to “active” accounts, 

defined as accounts which averaged more than one customer-initiated debit transaction per 

month over the period for which we have data and during which the account was open. In all 

analyses, only active accounts are included. Analysis is conducted at the account or transaction 

level, and therefore the results reflect the relative number of accounts or transactions at the 

different study banks.

Overall, the data contain information on roughly two million accounts. As these samples come

from a small number of large banks, they cannot be considered fully representative of the 

checking account market as a whole. Nevertheless, we expect it is likely that they are similar to 

what one would observe at any institution that offers similar checking account and overdraft

products. Due to data availability and comparability issues, we cannot calculate all reported 

statistics for all study banks. We therefore calculate each statistic for the largest possible set of 

banks that the data will allow. As a consequence, results from different tables may not be

directly comparable, and considerable caution should be exercised when drawing conclusions 

that require inter-table comparison.

 

5 As is the case within the study banks’ total checking portfolios, many of the accounts in our sample files were not 

open for the entire 30-month period, and accounts may have opened before or during the sample period.

3.Average Checking Account 

Fees

Table 1 shows average net checking account fees,6 in dollars per account per month, across five 

major fee categories: ATM and Account Usage Fees7 (such as fees for wire transfers and money 

orders), Maintenance Fees (periodic fees that are often waived for consumers that meet balance 

or other account usage requirements), Transfer Fees,8 Other Fees (such as fees for stopped 

payments and returned deposit items), and Overdraft9 and NSF Fees. We see that Overdraft and 

NSF Fees make up more than half of net checking account fees at $5.21 per account per month. 

The second largest category is ATM and Account Usage Fees at $1.66 per account per month. 

Maintenance Fees comprise a smaller portion at $1.28 per account per month, reflecting the fact 

that many of the account holders at the study banks either utilize accounts with no maintenance 

fees (free checking) or meet the terms necessary to qualify for waivers of the maintenance fees 

associated with their accounts.

 

6 Net of fee waivers (automatic fee reversals) and identifiable fee refunds (discretionary fee reversals).

7 ATM fees include only those fees assessed by the study banks on their accountholders and do not include host fees 

incurred by accountholders charged by other institutions and third-party ATM deployers.

8 “Transfer fees” are fees charged by banks for automatically transferring funds from a linked account (e.g., a linked 

savings account) to a checking account in order to cover an item that exceeds the checking account balance.

9 “Overdraft Fees” includes sustained negative balance fees, which are charged by some banks when an account 

holder fails to bring his or her account balance positive within a specified period of time after the account balance 

becomes negative.
9 CFPB DATA POINT: CHECKING ACCOUNT OVERDRAFT

TABLE 1: MONTHLY NET CHECKING ACCOUNT FEES PER ACCOUNT

Table 1 also shows net checking account fees by opt-in status. Overall, 14.3 percent of account 

holders in our study bank sample were opted in during the period of study.10 Not surprisingly, 

opted-in accounts experienced higher Overdraft and NSF Fees as compared to accounts that are 

not opted-in, both in absolute terms and as a fraction of the total fees they represent. In fact, 

among opted-in accounts, Overdraft and NSF Fees per account per month were over 14 times 

greater than Maintenance Fees ($21.61 vs. $1.53). Overdraft and NSF Fees constituted a 

significant share of the total net account fees for non-opted-in accounts as well; even within this 

class of accounts, Overdraft and NSF Fees constituted over 40 percent of net checking account 

fees at an average $2.98 per account per month. Note that the Regulation E opt-in requirement 

only covers ATM and non-recurring debit card transactions, so even non-opted-in accounts can 

incur overdraft fees on, for example, checks or ACH transactions.

 

10 We categorize each account as either opted-in or not opted-in for the entire study period. If the account changed 

status, we categorize it according to the status it had for the majority of the period. It should be noted that records of 

changing opt-in status are very rare among our study banks’ account holders. If a bank did not provide its 

customers with the opportunity to opt in, all accounts at that bank would be treated as not opted in.

Fee Type Overall Accounts Opted In Accounts Not Opted In 

ATM and Account 

Usage Fees $1.66 $2.08 $1.61

Maintenance Fees $1.28 $1.53 $1.24

Transfer Fees $0.54 $0.85 $0.50

Other Fees $1.18 $3.02 $0.93

Overdraft and NSF Fees $5.21 $21.61 $2.98

Total $9.87 $29.09 $7.26

TABLE 2: COMPOSITION OF GROSS OVERDRAFT AND NSF FEES

Table 2 breaks down gross Overdraft and NSF Fees into three categories: Overdraft Fees, NSF 

Fees, and Sustained Negative Balance (SNB) Fees.11 Not all banks charge SNB Fees; these results 

are for study banks that charge SNB Fees. Over 70 percent of the fees in this table are Overdraft 

Fees. Because our study banks (and most institutions) generally charge the same fees for 

overdrafts and NSFs, this indicates that most transactions that exceed a consumer’s balance are 

paid – as opposed to returned – by our study banks. SNB Fees make up 9 percent of Overdraft 

and NSF Fees at the banks that charge SNB Fees.

 

11 Gross fees are fees before deducting fee waivers (automatic fee reversals) and identifiable fee refunds (discretionary 

fee reversals).

Fee Type Share

Overdraft Fees 71.9%

NSF Fees 18.9%

Sustained Negative Balance Fees 9.2%
11 CFPB DATA POINT: CHECKING ACCOUNT OVERDRAFT

4.Distribution of Overdraft 

Frequency

We categorize accounts into four groups based on the frequency of overdraft transactions they 

experience per year, including transactions that do not incur a fee or those for which the fee was

eventually reversed: never, one to three, more than three and up to 10, and more than 10.12

Table 3 shows the distribution of accounts and overdraft fees by these overdraft frequency

groups. It shows that a relatively small number of account holders are responsible for most 

overdrafts, with 8.3 percent of account holders who overdraft more than 10 times per year 

responsible for 73.7 percent of overdraft fees. A majority of accounts, 69.8 percent, do not incur 

any overdrafts, and 82.3 percent of accounts incur 3 or fewer overdrafts.13 This table also shows 

the average amount of gross fees paid by account holders in different overdraft frequency 

categories. Because many overdrafts do not result in fees, such as overdrafts covered by a de 

minimis policy or debit card transactions that result in an overdraft for an account holder who is 

not opted-in, the dollar amounts may be less than the number of overdrafts multiplied by the 

overdraft fee amount.

 

12 The analysis in this section uses only information from the last 12 months of the time period covered by the data.

Those accounts that were open for only part of that period are assigned to an overdraft frequency category by 

annualizing their count of overdrafts.

13 These results are slightly different from those reported in the White Paper, which, based upon aggregate-level data 

supplied by the banks, reported that between 73 percent and 80 percent of study bank customers incurred no 

overdrafts. There are several methodological differences between these calculations and those reported in the White 

Paper, especially the exclusion here of inactive accounts. CFPB Study of Overdraft Programs: A White Paper of 

Initial Data Findings, pp. 3, available at http://files.consumerfinance.gov/f/201306_cfpb_whitepaper_overdraftpractices.pdf.

TABLE 4A: DISTRIBUTION OF ACCOUNTS AND GROSS OVERDRAFT FEES BY 

OVERDRAFT FREQUENCY AND OPT-IN STATUS

Table 4a. shows the distributions of account overdraft frequency among opted-in and nonopted-in accounts. Much like Table 1, we can see that accounts which overdraft most frequently 

(more than 10 items per year) are three times as prevalent among accounts that are opted in; 

indeed, nearly one in five of the opted-in accounts has more than 10 overdraft items per year. 

The fee distribution is correspondingly skewed toward the most frequent overdrafters: 17.8 

percent of the accounts representing 84.3 percent of the fees among Opted-In Accounts, and 5.9 

percent of the accounts representing 61.6 percent of the fees among Non-Opted-In Accounts. 

Note that the difference between Opted-In and Non-Opted-In accounts in overdraft frequency 

and overdraft fees may be an effect of opting in or a selection effect from the choice to opt in; the 

underlying causal relationship would require further study.

TABLE 4B: DISTRIBUTION OF ACCOUNTS AND GROSS OVERDRAFT FEES BY 

OVERDRAFT FREQUENCY AND AGE

Table 4b. breaks down the distribution of accounts by age of the account holder and the 

frequency of overdrafts. We find that the share of accounts in higher overdraft categories 

generally declines with account holder age, and the share of accounts without any overdrafts 

rising from 61.5 percent of the 18-25 age group to 84.6 percent of the 62 and over age group. 

Further analysis is needed to determine the underlying mechanisms of this relationship, such as 

differences in debit card use, differences in average balances, or other factors.

TABLE 4C: DISTRIBUTION OF ACCOUNTS AND GROSS OVERDRAFT FEES BY 

OVERDRAFT FREQUENCY AND MONTHLY DEBIT CARD INTENSITY

Table 4c. reports the distribution of overdraft frequency by the intensity of debit card use. Here 

we see that overdraft incidence changes consistently with debit card use. On one end of the 

distribution, 92.3 percent of accounts that do not use debit cards have no overdrafts in a year of 

account use. Only 0.6 percent of these accounts incur more than 10 overdrafts per year. At the 

other end of the distribution, accounts that use their debit cards more than 30 times per month 

have the lowest percentage of non-overdrafters (51.2 percent) and the highest percentage of 

most frequent overdrafters (18.0 percent).

5.Overdrafting by Transaction 

Type

We categorize debit transactions into six transaction types: ACH (including pre-authorized 

ACH), ATM, Check, Debit Card (point of sale and recurring), Other (such as online transfers), 

and Teller. Fees, adjustments, and other bank-initiated transactions are not included within 

these categories. Table 5 shows the number of debit transactions per account per month across 

these transaction types, both overall and by opt-in status.14 By far the most frequent transaction

type is Debit Card with 17.4 transactions per account per month. Debit Card use is even more 

frequent among opted-in accounts at 23.9 transactions per account per month.

 

14 Gross transactions include transactions that may have been reversed at a later time as well as check and ACH 

transactions returned for insufficient funds. As noted earlier, these totals do not include declined debit card POS 

and ATM transactions.

TABLE 6: MEDIAN VALUE OF OVERDRAFT TRANSACTIONS CHARGED A FEE BY

Table 6 shows the median sizes of transactions that lead to an overdraft with a fee charged by 

the bank. These figures do not include NSF transactions. We see that the median transaction 

size of Debit Card overdrafts that result in an overdraft fee is the smallest at $24, while Teller 

overdrafts resulting in fees are the largest at $150. The median transaction size over all overdraft 

transactions that result in fees is $50.

TABLE 7: PERCENTAGE OF TOTAL VALUE OF OVERDRAFT TRANSACTIONS NOT 

COVERED BY ACCOUNTHOLDER FUNDS BY TRANSACTION TYPE

When an overdraft takes place, the bank covers the portion of the transaction that is not covered 

by the funds in the account at the time. Table 7 shows the total percentage of funds from all 

overdrafts that are covered by the study banks rather than covered by funds in the account at the 

time of the overdraft.15 It shows a wide range across transaction types; for example, 42.4 percent 

of the total dollar amount of Check overdraft transactions is not covered by funds in consumers’ 

accounts, while that figure is 61.3 percent for Debit Card transactions. Note that, on average,

Debit Card transactions are substantially smaller than Check transactions, so the dollar amount 

covered by the banks may still be higher for check transactions.

 

15 These calculations are made using the ledger balance of the account at the time the transactions settles.

Transaction Type Percentage

ACH 49.1%

ATM 61.8%

Check 42.4%

20 CFPB DATA POINT: CHECKING ACCOUNT OVERDRAFT

TABLE 8: SHARE OF TRANSACTIONS THAT ARE OVERDRAFT OR NSF BY 

TRANSACTION TYPE AND OPT-IN STATUS

Table 8 shows the share of transactions that are paid as Overdraft or returned as NSF for the 

various transaction types, including both transactions that result in fees and transactions that do 

not result in fees. The share of transactions that are Overdraft transactions is similar for Check, 

Debit Card, ACH and ATM transactions at around 0.9 – 1.0 percent. The share that are returned 

as NSF is lower, and the transaction type with the highest NSF likelihood is ACH at 0.63 

percent. When breaking out Opted-In and Non-Opted-In accounts, an interesting result 

emerges: among Opted-In accounts, the probability of overdrafting is significantly higher across 

all transaction types, not just those covered by the Regulation E opt-in requirement (ATM and 

non-recurring debit card transactions). For example, for ACH transactions, the Overdraft share

for Opted-In accounts is more than double the share for accounts not opted in (1.85% vs. 0.76%) 

and for Check transactions the share is triple (2.56% vs. 0.82%).16

TABLE 9: AVERAGE MONTHLY NUMBER OF OVERDRAFT AND NSF TRANSACTIONS 

PER ACCOUNT BY FEE STATUS

Finally, Table 9 shows the number of Overdraft or NSF transactions per account per month, 

categorized by whether they were paid (leading to an Overdraft) or rejected (leading to an NSF) 

and whether or not the transaction incurred a fee. Again, these statistics are shown both overall 

and by opt-in status. Opted-in customers have seven times as many overdraft transactions with 

a fee (0.516 per month) as customers who are not opted in (0.072 per month). They also have 

more NSF transactions with fees, but this difference is smaller (0.074 per month versus 0.030 

per month). As previously noted, these calculations do not include ATM or debit card 

transactions that were declined at the point of sale.

 

16 Although the Regulation E opt-in requirement covers only non-recurring debit card transactions and our 

classification of Debit Card transactions includes recurring transactions, non-recurring transactions that are 

covered by Regulation E make up the vast majority of all Debit Card transactions.

22 CFPB DATA POINT: CHECKING ACCOUNT OVERDRAFT

6.Negative Balance Episodes

A negative balance episode is the sequence of days following an initial overdraft during which an 

account holder’s balance remains negative. A negative balance episode commences on the 

business day when a bank posts the transaction that results in a negative account balance. It 

ends on the business day the bank posts the transaction that brings the account balance positive. 

Between the starting transaction and the ending transaction there may or may not be additional 

overdraft or NSF transactions. Figure 1 shows the distribution of negative balance episodes that 

began on a day when an overdraft transaction was posted to the account.17 We see that most 

negative balance episodes are very short. In 29 percent of cases, the account holder returns the 

account balance positive the calendar day after the account goes negative. More than half of all 

episodes last three days or fewer, and 76.1 percent last a week or less. A small number of 

episodes last much longer: 2.8 percent of episodes last 45 days or more and some of these result 

in an account closure and negative balance charge-off.

 

17 These calculations are made using the accounts’ ledger balances. We exclude a small number of situations in which 

the ledger balance was not negative at the end of the day on which the overdraft transaction posted, which could 

arise if the transaction was identified as an overdraft at the time it was authorized but funds were deposited into the 

account prior to the end of the day on which the transaction settled.
