What is APR?
APR stands for Annual Percentage Rate. It's the total cost of borrowing money over a year, expressed as a percentage. Unlike the interest rate, which only reflects the cost of borrowing the principal amount, APR also includes additional fees such as origination charges, closing costs, and other finance charges. This makes it a more accurate reflection of the true cost of a loan.

How to Calculate APR
While the exact formula can vary depending on the type of loan or product, most APR calculations involve using the loan amount, monthly payment, and term. The APR calculator above uses a numerical method called Newton-Raphson to estimate the interest rate.
The general steps to calculate APR are:
- Gather all loan details: amount, term, monthly payment
- Use an iterative method like Newton-Raphson to solve for the interest rate
- Multiply the monthly rate by 12 to get the annual rate
- Add any applicable fees or charges
This calculator handles all of that automatically — just enter your numbers!
