Estimate a fixed monthly payment, total interest and total repayment using the amount borrowed, APR and term.
The payment assumes a fixed rate and equal monthly payments. Fees are shown separately unless added to the loan amount.
A longer term can lower the monthly payment while increasing total interest. Review the APR, finance charge, fees and total repayment before choosing an offer.
Educational estimate only; not a lender offer or approval.
A fixed-payment loan spreads principal and interest across a stated term. The monthly payment is useful for budgeting, but total interest and fees determine the broader borrowing cost. Two offers with similar payments can have different principal amounts, terms or annual percentage rates.
The calculator converts the annual rate to a periodic rate and applies the standard amortization formula over the number of monthly payments. It assumes a fixed rate, equal payments and no additional fees unless included in the entered principal.
APR can incorporate certain finance charges, making it more useful for comparing covered offers.
Use the loan-payoff calculator when you want to test recurring or one-time additional principal.
Using the standard amortization formula, a $25,000 loan at 8.5% APR over five years has an estimated payment of $512.91 per month. Over 60 payments you would repay about $30,774.80, of which about $5,774.80 is interest. Shortening the term to three years raises the payment to $789.19 but cuts interest to about $3,410.78, a saving of roughly $2,364.01. Stretching to seven years lowers the payment to $395.91 but raises interest to about $8,256.62, roughly $2,481.82 more than the five-year term.
| Term | Monthly payment | Total interest | Total repaid |
|---|---|---|---|
| 3 years (36 payments) | $789.19 | $3,410.78 | $28,410.78 |
| 5 years (60 payments) | $512.91 | $5,774.80 | $30,774.80 |
| 7 years (84 payments) | $395.91 | $8,256.62 | $33,256.62 |
Illustration only: fixed 8.5% APR, no fees, equal monthly payments. Your lender's quote may differ.
A lower payment is not automatically a cheaper loan. Extending the term usually keeps principal outstanding longer, which can increase total interest. Compare the payment with total interest, total repayment, fees and the amount of cash you actually receive after any origination charge.
IQlator uses a standard fixed-payment amortization model for this educational estimate. Your lender's disclosures and contract control the actual cost.

Schedule assumes a fixed APR and equal monthly payments; lender rounding and fees can differ.
Fees, term length and the amount actually financed can change the total cost even when the stated interest rate is similar. Compare APR and total repayment, not payment alone.
