APR: The True Cost of Borrowing—Including Hidden Fees
APR (Annual Percentage Rate) is the real cost of borrowing, including origination fees, points, and closing costs. Required by the Truth in Lending Act since 1968, APR lets you compare loans apples to apples. A 6.5% rate with $8K in fees has a 6.75% APR—the number that matters.
Why This Matters for Your Finances
Why: APR matters because the interest rate alone hides thousands in fees. A mortgage at 6.5% with $8K in closing costs has a 6.75% APR—that spread represents real money. Credit cards at 18.99% APR compounded daily equal 20.89% APY—the rate you actually pay.
How: Enter your loan amount, stated interest rate, term, and all fees (origination, processing, points, closing costs). The calculator solves for APR using the standard TILA formula and shows fee-by-fee impact in basis points. Compare multiple offers side by side.
- ●Always compare APR—not just the rate. A 6.0% loan with $10K fees may cost more than 6.5% with no fees.
- ●TILA requires APR on Loan Estimate and Closing Disclosure. If it's missing, ask—it's your right.
- ●Discount points: if you'll stay past 5–7 years, they can save money. Otherwise, skip them.
- ●Read 0% APR fine print—many promotions charge retroactive interest if the balance isn't paid in full.
