Annual Percentage Rate (APR)
A standard calculation used by lenders. It is designed to help borrowers compare different loan options. For example, a loan with a lower stated interest rate may be a bad value if its fees are too high. Likewise, a loan with a higher stated rate with very low fees could be an exceptional value. APR calculations incorporate these fees into a single rate. You can then compare loans with different fees, rates or different terms.

APR after taxes
Annual percentage rate after taxes are taken into account. Unlike your after-tax interest rate the APR after taxes takes closing costs into account.
