How much can a licensed lender in Iowa charge on an installment loan? Since July 1, 2026, the ceiling is 3% a month, or 36% a year, on regulated loans. An installment loan is a personal loan you repay in fixed payments over months.

The 36% ceiling is new. Before July 1, the cap fell as the loan got bigger, and only the smallest balances could be charged the top rate. That matters if you are shopping for one of these loans now, and it matters if you plan to take out a mortgage soon, because the loan will show up in your file.

Who licenses these lenders, and under which law

Installment lenders in Iowa fall under Iowa Code Chapter 536, the Iowa Regulated Loan Act. Any business making these loans needs a license from the superintendent of banking. To get one, an applicant has to show at least $5,000 in liquid assets and post a surety bond, which is a guarantee that pays out if the lender breaks the rules. The bond was historically set at $25,000 and can be adjusted by rule.

A second law applies on top of the first. The Iowa Consumer Credit Code, Chapter 537, covers any consumer loan a Chapter 536 licensee makes. Where the two laws conflict, the Consumer Credit Code wins. If a licensee breaks it, that also counts as a violation of Chapter 536.

One flat cap replaced a sliding one

Under the old schedule, dating to 1965, lenders could charge 3% a month on balances up to $150, then 2%, 1.5% and 1% on larger slices. House File 2329 swept those tiers away. It passed the House 62 to 29 and the Senate 34 to 11. The Legislature's record gives the governor's signing date as May 2, 2026, and the governor's office gives May 3. Either way, the law took effect July 1.

According to Weiner Brodsky Kider, a law firm that advises lenders, the new law applies 3% a month to all regulated loans regardless of balance. The biggest change is on larger loans. A trade group that lobbied for the bill, the American Fintech Council, projects that about 250,000 more Iowans could borrow each year. That figure is the industry's own estimate. Nobody has measured it yet.

What these sources leave open

The statute and the reporting do not say how long these loans must run. They also do not say how online lenders are licensed or whether lenders are routing loans through out-of-state banks or tribal entities to charge more. We also could not confirm which credit unions in Iowa offer small alternative loans, or whether the state runs a named assistance program. The Division of Banking is the office to ask about any of these.

Two checks settle most of the risk. First, ask the lender whether it holds an Iowa regulated loan license. Second, look at the APR on the disclosure. The APR is the yearly cost of the loan including fees. On a regulated loan made since July 1, it should not exceed 36%. A shorter loan due on your next payday is a different product with its own rules, covered in payday loans in Iowa.

If you are closing on a house soon

An underwriter reading your bank statements will see the loan deposit and the monthly payments. Expect a request for a letter of explanation, which is a short signed note saying what the loan was and what it paid for. While the loan is open, its monthly payment counts toward your debt-to-income ratio. That ratio compares your monthly debts with your income, and it limits how large a mortgage you can get.

Paying the loan off before you apply removes the payment from that ratio. The payoff still leaves a trail, so keep the payoff letter. How far back your lender looks, and how it treats a recent payoff, depends on the lender, so ask your loan officer before you move any money.
