APR vs Interest Rate
An interest rate and APR can describe different aspects of borrowing costs, depending on the product and jurisdiction.
How the math works
The interest rate is the base cost of borrowing the principal. APR (Annual Percentage Rate) folds in certain required fees — like origination fees or mortgage points — alongside the rate, which is why APR is usually the higher of the two numbers on the same loan.
Worked example
A mortgage advertised at a 6.25% interest rate might carry a 6.48% APR once a $2,500 origination fee is factored in over the loan term — the rate tells you the base cost, the APR gives a fuller (though still incomplete) comparison figure.
What to watch for
- APR is designed for comparing loans of the same type and term — it's less reliable for comparing across very different term lengths
- Not all fees are captured in APR (some third-party fees are excluded depending on the product and jurisdiction)
- A lower rate with a much higher APR usually signals higher upfront fees baked into that particular offer
Practical takeaway
Use the interest rate to estimate your payment, and APR as a secondary check for how much upfront fees are adding to the real cost of a specific offer.
