Annual Percentage Yield (APY) is the yearly rate of return on investments. Annual Percentage Rate (APR) typically represents the cost of borrowing money – or the rate of interest accrued on loans each year. From a consumer perspective, you’ll see APY associated with things like savings accounts, checking accounts or share certificates and APR on your auto loan, mortgage or credit card debt.
Although both APY and APR are measures of interest, APR can incorporate other costs, like fees. Various origination or management fees are broken up and spread over the life of the loan by dividing the fees by the number of payment periods.
From a borrower’s perspective, it’s often preferable to just have those added fees rolled into your monthly interest and principal payments rather than having to pay a large lump sum once a year or at the start or end of the loan.
APY doesn’t incorporate any kind of fees like this, so the APY you see associated with a savings product is purely the yield (annual interest earned) of the account.
Although APR and APY are used for opposing purposes, there are some significant similarities in terms of function and calculation. Maybe the most obvious similarity is the first word: annual. They provide a standardized way to represent the yearly cost of a loan (APR) or the annual earnings on an investment, savings or checking account (APY).
APY reflects the total amount of interest the balance of an account will earn through compounding interest. Compounding occurs when the interest earned is added to the principal, and future interest calculations are made using the increased balance.
APR uses a simple interest calculation rather than a compounding interest calculation. The principle of a loan and the interest is divided into however many payments are required to pay off the amount within the loan term, or the life of the loan. The breakdown of interest and principal in each payment can be found in the loan’s amortization schedule. At the start of the loan, when the interest on the loan is much larger than the principal, most of your payment will go toward interest.
Knowing the principal, rate and term allows you to see the exact amortization schedule before you ever sign any loan papers. APY is a bit less predictable because the amount of money you invest or save isn’t set at the very start, except in the case of share certificate or certificate of deposit products.
Compounding frequency varies, with savings or checking accounts potentially having daily compounding, monthly compounding, quarterly compounding, semiannual compounding (twice per year) or annual compounding. The interest is calculated based on the balance of the account at the time of compounding.
Daily compounding is best for savers since the daily interest will be calculated and added quickly for new deposits. Frequent compounding is most impactful if you’re regularly making deposits.
