The Annual Percentage Rate, which must be reported by lenders under Truth in Lending
regulations, is a comprehensive measure of credit cost to the borrower that takes account
of the interest rate, points, and flat dollar charges.
The Annual Percentage Rate is also adjusted for the time value of money, so that dollars paid by the borrower up-front carry a heavier weight than dollars paid ten years down the road. However, the APR is calculated on the assumption that the loan runs to term, and is therefore potentially deceptive for borrowers with short time horizons.
