# Understanding the Earnings Credit Rate (ECR): A Key Banking Metric

## What Is the Earnings Credit Rate (ECR)?

The earnings credit rate (ECR) is the interest a bank pays on customer deposits. It is used mainly for institutional deposits and helps offset banking service fees on accounts that don’t earn interest. The ECR is often tied to the U.S. Treasury bill rate, which makes it a safe and reliable benchmark. By reducing costs on services, it plays an important role in shaping financial strategies and business decisions.

### Key Takeaways

*   The earnings credit rate (ECR) is a bank-calculated interest rate for non-interest-bearing accounts to offset service charges.  
    
*   ECRs help banks reduce customer fees on services like checking accounts, credit cards, and business loans.  
    
*   The ECR is typically based on the U.S. Treasury bill rate and applied to collected balances.  
    
*   Regulation Q led banks to adopt ECRs to provide benefits on non-interest-bearing accounts.  
    
*   Banks have discretion in setting ECRs, which can be more attractive when money market yields are low.

## How the Earnings Credit Rate Affects Your Bank Fees

Banks use ECRs to lower fees for services like checking, savings, debit and credit cards, business loans, and cash management, including [payroll](https://www.investopedia.com/terms/p/payroll.asp) and merchant services

ECRs are paid on [idle funds](https://www.investopedia.com/terms/i/idlefunds.asp), which reduce bank [service charges](https://www.investopedia.com/terms/s/service-charge.asp). Customers with larger deposits and balances tend to pay lower bank fees. ECRs are visible on most U.S. commercial account analyses and billing statements.

Banks have discretion in setting earnings allowances. While ECR can offset fees, depositors are only charged for services they use individually, not combined with others.

## The Origins and Evolution of the Earnings Credit Rate

The concept of ECR began with [Regulation Q](https://www.investopedia.com/terms/r/regulationq.asp), which stopped banks from paying interest on checking deposits. The 1933 [Glass-Steagall Act](https://www.investopedia.com/articles/03/071603.asp) aimed to curb loan sharking and predatory practices

The act subsequently supported consumers in releasing funds from checking accounts and shifting them to money market funds. Following Regulation Q, many banks decided to offer “soft dollar” credits on these non-interest-bearing accounts to offset banking services.

ECRs usually apply to "collected" balances, not "ledger" or "floating" ones. Depository accounts like lockboxes have float while deposits clear and are unavailable. Collected balances are funds ready for transfer or investment.

## Situations Where Earnings Credit Rate Becomes More Beneficial

When money market funds yield near zero (e.g., during the 2008 financial crisis), deposit accounts offering ECRs can become more attractive to corporate treasurers. Yet, in times of rising rates, these treasurers may look for [financial instruments](https://www.investopedia.com/terms/f/financialinstrument.asp) with a higher yield than ECRs. These could include money-market funds or even relatively safe and liquid bond funds.

## What Is the Difference Between ECR and Hard Interest?

Hard interest rates are generally higher than ECRs. One reason is that ECRs are not taxable, whereas hard interest rates are.

## What Is the Difference Between Interest Earned and Interest Rate?

The interest rate is a percent of your total deposits, paid to you as interest earned.

## What Is ECR for Banks?

The earned credit rate is an interest rate many banks give their institutional customers on their balances.

## The Bottom Line

The earnings credit rate allows banks to help their customers save on fees by using an imputed interest rate on non-interest-bearing accounts. It’s usually tied to safe rates like U.S. Treasury bills and is calculated daily. ECRs started with Regulation Q, which once limited banks from paying interest. They are still useful because they’re non-taxable. Customers benefit when ECRs reduce costs on services like checking, loans, or cash management, and they are especially appealing when money market yields are low.
