Estimate APR and compare it with the note interest rate after including loan fees and closing costs.
Loan cost comparison
An APR calculator helps borrowers compare the interest rate with a broader annualized cost estimate. The interest rate is important because it drives the principal and interest payment, but fees and closing costs can change the true cost of borrowing.
This tool estimates monthly payment, total interest, total loan cost, estimated APR, and the difference between the interest rate and APR. It uses loan fees and closing costs as simplified finance charges spread over the loan term.

Guide
The interest rate is the rate used to calculate interest on the loan balance. APR, or annual percentage rate, is intended to help borrowers compare loan offers by reflecting interest plus certain finance charges. That is why APR is often higher than the note rate.
Lenders disclose APR because two loans can have the same interest rate but different fees. A loan with a slightly lower rate and high fees may not be cheaper for a borrower who plans to move or refinance soon. APR gives one standardized comparison point, though it still requires context.
This calculator estimates the normal monthly payment from the loan amount, rate, and term. It then adds loan fees and closing costs to the total borrowing cost and converts that cost into a simplified APR estimate. The result is educational, not an official Truth in Lending calculation.
A common misconception is that APR equals the monthly payment rate. It does not. The note interest rate still drives the scheduled payment. APR is more useful for comparing cost across offers, especially when fees differ.
A $350,000 loan at 6.5% for 30 years may have a monthly principal and interest payment of about $2,212. If fees and closing costs total $9,500, the estimated APR may be higher than 6.5% because those costs increase the total cost of borrowing.
