Payday Loan Costs in Iowa
A licensed lender can charge $15 on the first $100 borrowed and $10 (pro rata) for each additional $100 or portion thereof - labeled "finance charge" on your agreement - on loans up to $500, with terms up to 31 days. Your total outstanding payday balance across all Iowa lenders can't exceed $500, tracked through a statewide database.
On a $300 loan due in 14 days, the maximum fee is $35 ($15 + $10 + $10), making your total repayment $335. Your agreement will show roughly 304% APR - that's the 14-day fee scaled to a full year, required by federal disclosure rules.
- Rollovers are prohibited - the lender can't extend your loan for an additional fee.
- The returned payment fee - labeled "NSF fee" on your agreement - is capped at $15.
- A database verification fee of up to $1 per transaction may appear as a separate line item; question any verification charge above that amount.
If an offer exceeds these limits, verify with the Iowa Division of Banking.
Installment Loan Costs in Iowa
Lenders licensed under Iowa's Regulated Loan Act (Iowa Code Chapter 536) use a declining-balance interest model with tiered rate caps based on your unpaid principal balance.
| Unpaid Balance Tier | Maximum Monthly Rate | Approximate Annual Rate |
|---|---|---|
| First $150 | 3% / month | 36% annual |
| $150.01–$300 | 2% / month | 24% annual |
| $300.01–$700 | 1.5% / month | 18% annual |
| Over $700 | 1% / month | 12% annual |
Iowa Code Chapter 536 does not specify a separate origination fee cap - confirm with your lender whether any upfront fee applies and verify the amount before signing.
On a $1,000 Regulated Loan at the tiered declining-balance rates above for 12 months, you'd repay approximately $1,109 total - roughly $109 in interest plus $1,000 in principal, before any additional fees.
- Refinancing restarts interest on the new amount - compare your remaining balance to the new loan's total of payments before you agree.
- The returned payment fee cap is the same as payday - $15; see payday loan costs above.
- Iowa Code Chapter 536 does not specify a state late fee cap - ask the lender for the exact amount and grace period before you sign.
- You can prepay in full at any time - interest stops accruing on the payoff date; see the Iowa installment loans page for repayment details.
If an offer exceeds these limits, verify with the Iowa Division of Banking.
