APY vs APR: What's the Difference?
How annual percentage yield and annual percentage rate describe returns and borrowing costs differently — and why the higher number is not always 'better'.
Two ways to annualize a rate
APR (annual percentage rate) is commonly quoted for loans and credit products. It expresses the cost of borrowing over a year, often including certain fees spelled out by disclosure rules.
APY (annual percentage yield) is commonly quoted for savings and interest-bearing accounts. It reflects compounding — how often interest is credited and earns interest itself.
Same nominal rate, different compounding frequency → different APY. That is why savings ads emphasize APY while loan ads emphasize APR.
Compounding matters for savers
A 5% nominal rate compounded monthly produces a higher APY than 5% compounded annually because each interest payment starts earning its own interest sooner.
When comparing savings accounts, use APY apples-to-apples. A 'high interest' headline with monthly compounding can beat a slightly higher nominal rate compounded yearly.
APY calculators translate stated rate and compounding frequency into one comparable percentage.
APR on loans is not the whole story
APR attempts to bundle some costs beyond the note rate, but not every fee or future event (rate resets, prepayment penalties) fits neatly into one number.
For mortgages, APR spreads certain closing costs across the loan term in the disclosure math. Short-term holders may care more about upfront cash and note rate than APR alone.
Credit card APR applies to balances you carry; paying in full avoids interest even if the APR is high on paper.
Educational, not advice
FinKit APY tools apply standard compound-interest formulas to inputs you choose. They do not guarantee future bank rates or investment returns.
Neither APR nor APY replaces reading product disclosures. Promotional rates expire; tiered balances pay different yields.
