APR calculator
APR Calculator
Estimate the annual percentage rate of a loan using the loan amount, stated interest rate, upfront fees and repayment term. APR can help you compare loan offers because it includes more than just the interest rate.
Compare the true cost of borrowing
A loan with a lower interest rate is not always the cheaper loan if it has high origination fees, closing costs or other upfront charges. This calculator estimates how those fees affect the overall borrowing cost and converts the result into a simplified APR estimate.
Use the result as a planning estimate, not as a lender disclosure. Official APR can depend on lender-specific rules, timing of fees, compounding, payment schedule and regulatory calculations.
APR estimate breakdown
This table shows the main inputs and outputs used to estimate APR. The fee line is important because fees can make APR higher than the stated interest rate.
| Item | Estimated amount |
|---|---|
| Loan amount | $20,000.00 |
| Loan fees | $500.00 |
| Fees as percentage of loan | 2.50% |
| Estimated amount received after fees | $19,500.00 |
| Loan term | 5 years |
| Monthly payment | $405.53 |
| Total interest | $4,331.67 |
| Total repaid plus fees | $24,831.67 |
| Estimated APR | 4.83% |
How fees change the APR estimate
This quick comparison keeps the loan amount, interest rate and term the same, but changes the fee amount. Higher fees generally increase the estimated APR.
| Scenario | Fees | Estimated APR |
|---|---|---|
| Lower fee scenario | $0.00 | 4.33% |
| Current inputs | $500.00 | 4.83% |
| Higher fee scenario | $1,000.00 | 5.33% |
How this APR calculator works
APR, or annual percentage rate, is a way to express the yearly cost of borrowing. Unlike the interest rate alone, APR may include certain loan fees. This calculator estimates the monthly payment from the stated interest rate, then adds the loan fees to estimate total borrowing cost.
Interest rate vs APR
The interest rate is the cost of borrowing before some fees. APR is often higher because it can include additional borrowing costs. If a loan has no fees, the APR estimate may be closer to the interest rate. If a loan has large fees, the APR estimate may be noticeably higher.
Why loan fees matter
Fees can change the real cost of a loan. For example, a loan with an 8% interest rate and $500 in fees may cost more than a similar loan with the same rate and no fees. APR helps make that difference easier to compare.
Example APR estimate
Suppose someone borrows $20,000 for 5 years at an 8% stated interest rate and pays $500 in fees. The calculator estimates the monthly payment, total interest over the loan term and then adds the fee cost to estimate the annualized borrowing cost.
When APR is useful
APR can be useful when comparing personal loans, auto loans, mortgage offers or refinance options. It is especially helpful when two loans have different fees, terms or interest rates.
Important limitations
This is a simplified educational APR estimate. Actual lender APR can vary depending on fee type, payment timing, compounding, loan rules, credit profile, closing costs and regulatory disclosure methods. Use lender disclosures for official loan comparisons.
Frequently asked questions
Why is APR higher than the interest rate?
APR can be higher because it may include certain fees in addition to interest. A loan with origination fees or closing costs usually has a higher APR than its stated interest rate.
Does a lower interest rate always mean a cheaper loan?
Not always. A lower interest rate can still come with high fees. APR helps compare the broader borrowing cost, but you should also review total payments, monthly payment and lender terms.
Is this the same as a lender APR disclosure?
No. This calculator provides a simplified estimate for planning and comparison. Official APR disclosures may use more detailed lender and regulatory calculations.
Can APR be used for credit cards?
Credit card APR works differently because balances can change each month and interest may compound daily. This calculator is better for fixed-term loans with a known loan amount and repayment period.
