How Much Does a $300 Loan Cost in 2026?
A $300 loan is a small amount, but it is not always a cheap one, and the cost swings a lot with the APR. Repaid over six months, the same $300 costs about $32 in interest at a 36% APR, and around $430 at a 400% APR. This guide shows the honest numbers so you can borrow with your eyes open, and points to cheaper options worth checking first.
The cost by APR, in full
These figures assume a fixed $300 balance repaid in equal monthly payments over six months. The interest column is the true price of the loan.
| APR | Monthly payment | Interest paid | Total repaid |
|---|---|---|---|
| 36% | $55 | $32 | $332 |
| 100% | $66 | $94 | $394 |
| 200% | $83 | $197 | $497 |
| 400% | $122 | $430 | $730 |
Read the APR, not just the payment. A low monthly payment can hide a high total cost. On a $300 loan, the gap between a 36% and a 400% APR is nearly $400, for the exact same money over the same six months.
Why short-term APRs are so high
Short-term and small-dollar loans are priced with fees that are large relative to the amount borrowed and the short time you hold the money. Expressed as an annual rate, those fees translate into APRs that commonly exceed 200%, and sometimes much more. The law requires the lender to show you the APR and the total cost in a Truth-in-Lending disclosure before you sign, so always read that document and borrow only what you can repay on schedule.
How to lower the cost, or avoid it
- Compare the APR across lenders. The same request can draw very different offers, and a lower APR directly cuts the total cost.
- Borrow the smallest amount for the shortest term you can manage, since both drive the total interest.
- Check a credit-union PAL. A payday alternative loan caps the APR far below typical short-term products.
- Ask the biller first. A payment plan on a bill or medical charge is often free and avoids borrowing entirely.
- Avoid rolling the loan over. Renewing a short-term loan stacks new fees on top and is how a small balance becomes a large one.
Frequently asked questions
How much does a $300 loan cost?
Repaid over 6 months, about $32 in interest at 36% APR, but roughly $430 at 400% APR. Short-term APRs are often much higher than other credit, so the same $300 can cost very different amounts.
Why are short-term loan APRs so high?
The fees are large relative to a small amount borrowed over a short time. Review the lender's Truth-in-Lending disclosure for the exact APR and total cost before you sign.
Are there cheaper alternatives to a $300 short-term loan?
Often yes. A credit-union payday alternative loan, a lower-APR personal loan, a paycheck advance, or a payment plan with the biller can cost far less. Compare before you borrow.
