Frequently asked questions

What is APY and how is it different from APR?

APY (Annual Percentage Yield) is the real return on savings including compound interest, while APR (Annual Percentage Rate) ignores compounding. APY is always equal to or higher than APR for the same nominal rate.

How do you calculate APY from interest rate and compounding frequency?

APY = (1 + r/n)^n - 1, where r is the nominal annual interest rate and n is the number of compounding periods per year. The more frequently interest compounds, the higher the resulting APY.

Does more frequent compounding always give a higher APY?

Yes, for a given nominal rate, increasing compounding frequency (monthly, daily, etc.) raises APY, though the gains shrink as you approach continuous compounding.

Is a higher APY always better for savers?

Yes for deposits and savings accounts, a higher APY means more earnings on your balance over a year, assuming the rate and compounding stay constant.

Can APY be the same as the nominal interest rate?

Yes, APY equals the nominal rate only when interest compounds once per year (n = 1); with any more frequent compounding, APY will be slightly higher than the nominal rate.
