1% APR gap = thousands
APR vs. interest rate: the number lenders hide
Interest rate is the cost of borrowing the principal; APR includes the interest rate plus all loan fees, expressed as a yearly percentage. APR is always equal to or higher than the interest rate. Federal Truth in Lending Act requires lenders to disclose APR so borrowers can compare loans on equal footing — always compare by APR.

04 · ideas- APR includes fees that the interest rate ignores
- A 5.9% rate with $3,000 in fees can cost more than 6.2% with no fees
- Short-term loans exaggerate the impact of fees on APR
- Always compare APR, not the advertised interest rate
Interest rate = the annual cost of borrowing the principal, expressed as a percentage.
APR (Annual Percentage Rate) = the interest rate plus all fees and costs, also annualized. APR is always ≥ the interest rate.
A lender advertising 5.5% but charging $3,000 in origination fees on a $200,000 loan has an APR closer to 5.8%. The interest rate is not the price — the APR is.
Simple rule: When comparing loans, always use APR. Ignore advertised rates.
The exception: if you'll pay off the loan very early, APR overstates the fee impact (fees are spread over the full term, but if you refi in 3 years, the "annualized" calculation misleads). In that case, calculate total cost instead.
