APR Calculator
Use an APR calculator to compare stated interest with the real annual percentage rate after fees are included, whether for a general loan or a mortgage scenario.
How to use this calculator
How APR differs from interest rate
APR stands for annual percentage rate. It reflects the cost of borrowing after interest and qualifying fees are combined, which makes it more useful than headline interest alone when comparing lenders or loan structures.
- Use General APR mode when the loan payment is defined by term, stated interest, compounding, and fee assumptions.
- Use Mortgage APR mode when you want to test how loan fees, points, and PMI change the real borrowing cost of a home loan.
- Compare APR carefully when fees differ between offers, because a lower interest rate can still cost more overall if the fee structure is heavier.

FAQ
Common APR questions
What is the difference between APR and interest rate?
The interest rate reflects the borrowing cost on principal only, while APR includes interest plus certain fees and charges so the total annual borrowing cost is easier to compare.
Why can APR be higher than the stated mortgage rate?
APR usually rises above the stated rate when lender fees, points, and mortgage insurance are included in the borrowing cost calculation.
Is APR the only number I should compare?
No. APR is very useful, but you should also compare upfront cash needed, repayment flexibility, total interest, and how long you expect to keep the loan.
