How it works

APR spreads origination fees, points, and other financing charges across the loan term, expressing the true cost as an annual rate. Formula: solve for the rate r in PV = Σ PMT/(1+r)^t over all payment periods. A lower APR means lower total cost even if the nominal rate looks similar. Balloon payments and prepayment penalties can distort APR comparisons.
