APY to APR Calculator – What Would the APR Be?

Written by:

On this page is an annual percentage yield to annual percentage rate or apy to apr calculator.

Sometimes you have an APY, or annual percentage yield, and need to compare to an APR, or annual percentage rate. APR does not tell you the true cost of debt or a loan since it isn't compounded; one way to fairly compare two terms is to convert the APY into an APR for a direct comparison (although it's usually safer to convert APR to APY).

Using the APY to APR Calculator

Here's what the tool needs to convert your annual yield or APY into an APR:

  • Interest Rate/APY (%) - The APY or the loan, investment, or other instrument with the compounded rate included.
  • Compounding Frequency - Choose how often the investment compounds interest.

APY to APR Output

When done, hit the "Compute APR" button to do the math. Here's the output:

  • Annual Percentage Rate (APR) (%) - The equivalent annual percentage rate, or APR, using your modeled assumptions.

Comparing Like Quantities

APR and APY are tricky topics, and sometimes (hopefully not often!) banks confuse the two rates to obfuscate comparisons. While I prefer to look at things on an annual basis, it's also valid to compare things as APRs – just make sure you compare like to like, whichever you choose.

If you do want to go the other way, here's that tool plus a few additional tricky yield and fixed income calculators to boot:
