# How to calculate annual percentage rate (APR)?

Answer:Lenders use different ways to calculate annual percentage rate (APR). The actuarial method and formula are the most popular ways for calculating APR. The Truth in Lending Act demands from lenders to disclose the APR to borrowers.

## How to calculate annual percentage rate (APR) precisely?

You can do the APR calculation on your own if you know what the lender fees are and how many of them are included in the APR. APR calculation varies not only because of the formulas used but also because lenders may not include or disclose certain closing costs that affect the APR.

To be precise about APR calculation, demand as many fees to be disclosed by the lender as possible. The best way to go is to collect GFEs and calculate the annual percentage rate (APR) on your own using a web APR calculator.

A loan locked for a longer period may have higher APR than a loan locked for a shorter term. Do not compare APR for loans with different amortizing periods. In general, it is better to calculate annual percentage rate (APR) on your own rather than compare APR from different lenders. Lenders use different methods, different fees and different software to calculate their annual percentage rate and the APR shown on their website usually is not enough to make the best informed decision.
