**Principal Funds, Inc. Summary Prospectus March 1, 2023**

Before you invest, you may want to review the Fund's Prospectus, which contains more information about the Fund and its risks. You can find the Fund's Prospectus, Statement of Additional Information, Reports to Shareholders, and other information about the Fund online at www.PrincipalAM.com/Prospectuses. You can also get this information at no cost by calling 1-800-222-5852 or by sending an email request to <u>prospectus@principalfunds.com</u>.

The Fund's Prospectus and Statement of Additional Information, both dated March 1, 2023, as may be amended or supplemented, are incorporated by reference into this Summary Prospectus.

**Objective**

The Fund seeks high current income.

**Fees and Expenses of the Fund**

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

If you purchase Institutional Class shares through certain programs offered by certain financial intermediaries, you may be required to pay a commission and/or other forms of compensation to the broker, or to your Financial Professional or other financial intermediary.

<sup>(1)</sup>

Principal Global Investors, LLC ("PGI"), the investment advisor, has contractually agreed to waive a portion of the Fund's management fees through the period ending February 29, 2024. The fee waiver will reduce the Fund's management fees by 0.015% (expressed as a percent of average net assets on an annualized basis). It is expected that the fee waiver will continue through the period disclosed; however, Principal Funds, Inc. and PGI, the parties to the agreement, may mutually agree to terminate the fee waiver prior to the end of the period.

**Example**

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The calculation of costs takes into account any applicable contractual fee waivers and/or expense reimbursements for the period noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **1 year** | **3 years** | **5 years** | **10 years** |
| **Institutional Class** | $61 | $197 | $344 | $772 |

---

**Portfolio Turnover**

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 48.10% of the average value of its portfolio.

**Principal Investment Strategies**

Under normal circumstances, the Fund invests primarily in below investment grade bonds and bank loans (sometimes called "high yield" or "junk"), which are rated, at the time of purchase, Ba1 or lower by Moody's Investors Service, Inc. ("Moody's") and BB+ or lower by S&P Global Ratings ("S&P Global") (if the bond or bank loan has been rated by only one of those agencies, that rating will determine whether it is below investment grade; if the bond or bank loan has not been rated by either of those agencies, those selecting such investments will determine whether it is of a quality comparable to those rated below investment grade). The Fund also invests in investment grade bank loans (also known as senior floating rate interests), securities of foreign issuers, and exchange-traded funds ("ETFs"). The Fund utilizes derivative strategies for managing fixed-income exposure. A derivative is a financial arrangement, the value of which is derived from, or based on, a traditional security, asset, or market index. Specifically, the Fund invests in credit default swaps to increase or decrease, in an efficient manner, exposures to certain sectors or individual issuers.

In managing the Fund, Principal Global Investors, LLC ("PGI"), the Fund's investment advisor, allocates the Fund's assets among multiple sub-advisors that use differing approaches in making their investment decisions, which include actively managed and more passive investment strategies. With respect to the passive strategy, the Fund uses a sampling methodology to purchase securities with generally the same risk and return characteristics as the Bloomberg U.S. Corporate High Yield 2% Issuer Capped Index (the "Index") in an attempt to match or exceed the performance of the Index.

Under normal circumstances, the Fund maintains an average portfolio duration that is within ±25% of the duration of the Index, which as of January 31, 2023 was 3.97 years. The Fund is not managed to a particular maturity.

**Principal Risks**

The value of your investment in the Fund changes with the value of the Fund's investments. Many factors affect that value, and it is possible to lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund are listed below in alphabetical order and not in order of significance.

**Bank Loans Risk.** Changes in economic conditions are likely to cause issuers of bank loans (also known as senior floating rate interests) to be unable to meet their obligations. In addition, the value of the collateral securing the loan (if any) may decline, causing a loan to be substantially unsecured. Underlying credit agreements governing the bank loans, reliance on market makers, priority of repayment, and overall market volatility may harm the liquidity of loans.

**Counterparty Risk.** Counterparty risk is the risk that the counterparty to a contract or other obligation will be unable or unwilling to honor its obligations.

**Derivatives Risk.** Derivatives may not move in the direction anticipated by the portfolio manager. Transactions in derivatives may increase volatility, cause the liquidation of portfolio positions when not advantageous to do so, and result in disproportionate losses that may be substantially greater than a fund's initial investment.

**•** **Credit Default Swaps.** Credit default swaps involve special risks in addition to those associated with swaps generally because they are difficult to value, are highly susceptible to liquidity and credit risk, and generally pay a return to the party that has paid the premium only in the event of an actual default by the issuer of the underlying obligation (as opposed to a credit downgrade or other indication of financial difficulty). The protection "buyer" in a credit default contract may be obligated to pay the protection "seller" an up-front payment or a periodic stream of payments over the term of the contract, provided, generally, that no credit event on a reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the "par value" (i.e., full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amount, if the swap is cash settled. The Fund may be either the buyer or seller in the transaction.

**•** **Swaps.** Swaps involve specific risks, including: the imperfect correlation between the change in market value of the instruments held by the fund and the price of the swap; possible lack of a liquid secondary market for a swap and the resulting inability to close a swap when desired; counterparty risk; and if the fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements.

**Fixed-Income Securities Risk.** Fixed-income securities are subject to interest rate, credit quality, and liquidity risks. The market value of fixed-income securities generally declines when interest rates rise, and increased interest rates may adversely affect the liquidity of certain fixed-income securities. Moreover, an issuer of fixed-income securities could default on its payment obligations due to increased interest rates or for other reasons.

**Foreign Securities Risk.** The risks of foreign securities include loss of value as a result of: political or economic instability; nationalization, expropriation, or confiscatory taxation; settlement delays; and limited government regulation (including less stringent reporting, accounting, and disclosure standards than are required of U.S. companies).

**High Yield Securities Risk.** High yield fixed-income securities (commonly referred to as "junk bonds") are subject to greater credit quality risk than higher rated fixed-income securities and should be considered speculative.

**Investment Company Securities Risk.** A fund that invests in another investment company (for example, another fund or an exchange-traded fund (or ETF)) is subject to the risks associated with direct ownership of the securities in which such investment company invests. Fund shareholders indirectly bear their proportionate share of the expenses of each such investment company.

**Portfolio Duration Risk.** Portfolio duration is a measure of the expected life of a fixed-income security and its sensitivity to changes in interest rates. The longer a fund's average portfolio duration, the more sensitive the fund will be to changes in interest rates, which means funds with longer average portfolio durations may be more volatile than those with shorter durations.

**Redemption and Large Transaction Risk.** Ownership of the Fund's shares may be concentrated in one or a few large investors (such as funds of funds, institutional investors, and asset allocation programs) that may redeem or purchase shares in large quantities. These transactions may cause the Fund to sell securities to meet redemptions or to invest additional cash at times it would not otherwise do so, which may result in increased transaction costs, increased expenses, changes to expense ratios, and adverse effects to Fund performance. Such transactions may also accelerate the realization of taxable income if sales of portfolio securities result in gains. Moreover, reallocations by large shareholders among share classes of a fund may result in changes to the expense ratios of affected classes, which may increase the expenses paid by shareholders of the class that experienced the redemption.

Box 219971, Kansas City, MO 64121-9971 (regular mail) or 430 W. 7th Street, Ste. 219971, Kansas City, MO 64105-1407 (overnight mail); calling us at 1-800-222-5852; or accessing our website (www.principal.com).

**Tax Information**

The Fund's distributions you receive are generally subject to federal income tax as ordinary income or capital gain and may also be subject to state and local taxes, unless you are tax-exempt or your account is tax-deferred in which case your distributions would be taxed when withdrawn from the tax-deferred account.

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment, or to recommend one share class of the Fund over another share class. Ask your salesperson or visit your financial intermediary's website for more information.
