How this calculator works
APR reflects the annual cost of a loan after combining interest and certain fees. It gives borrowers a more complete comparison than rate alone, although exact lender disclosures can use more detailed methods.

Frequently asked questions
Is APR the same as interest rate?
Not always. APR includes certain fees in addition to the interest rate, which can make it higher than the base rate.
Why does APR matter?
APR can make lender comparisons more realistic because it reflects more of the true borrowing cost.
Will this always match a lender disclosure exactly?
No. Official loan disclosures may use more detailed assumptions, fee treatment, or payment schedules.
