APR and APY look almost identical, which is exactly why they trip people up — one letter apart, but they measure opposite sides of the same coin. APR describes what borrowing costs you; APY describes what saving earns you. The engine that separates them is compounding. Confuse the two and you will misjudge a loan or a savings account by more than you would guess. This is general information, not financial advice, so confirm the exact terms and current rates yourself.
What changed in 2026
- Rates that actually matter returned. With savings paying real yields again, the APY on your cash finally makes a visible difference — check current numbers, since they move.
- Disclosure stayed strict. Lenders must show APR and savings products must show APY, so the figures are there; the skill is reading them correctly.
- More accounts compound daily, which nudges APY further above the stated nominal rate — a small but real edge worth noticing.
What APR really measures
APR, the annual percentage rate, is the yearly cost of borrowing. For many loans it bundles in certain fees, giving a fuller picture than the interest rate alone. But APR is typically a nominal figure — it usually does not account for compounding within the year, so the true cost of a balance that compounds can be a touch higher than the APR suggests.
What APY really measures
APY, the annual percentage yield, is the yearly return on savings including compounding. Because it reflects interest earning interest, APY is always equal to or higher than the nominal rate. When you compare savings accounts, APY is the honest number — see HYSA vs money market account for where those yields live.

The takeaway: a lower APR is good on a loan; a higher APY is good on savings. Never compare one against the other.
How compounding drives the gap
Compounding means you earn (or owe) interest on interest already accrued. The more often it compounds — daily, monthly, yearly — the more APY pulls ahead of the plain rate. On savings that helps you; on a revolving balance it works against you, which is why a credit card's real cost can outrun its stated APR. Your credit affects the APR you are offered, so keeping your file clean via how to read a credit report pays off.
Pitfalls to avoid
- Comparing APR to APY. They are different measures. Compare loans by APR and savings by APY.
- Ignoring compounding frequency. Two accounts with the same nominal rate can have different APYs.
- Trusting the headline number. Fees, introductory periods, and compounding all change the real cost or return.
FAQ
Which is bigger, APR or APY?
For the same nominal rate, APY is higher because it includes compounding. That is why savings are quoted in APY and loans often in APR.
Why do lenders quote APR and banks quote APY?
APR presents borrowing cost, sometimes with fees. APY presents savings yield with compounding. Each convention flatters the way that product is usually shopped.
Does a lower APR always mean a cheaper loan?
Usually, but check fees and compounding. Two loans with the same APR can still differ in real cost depending on the fine print.
Can I convert between them?
There is a formula linking nominal rate, compounding frequency, and APY, but for shopping it is enough to compare loans by APR and savings by APY. This is general information, not advice.
