Calculate the Annual Percentage Rate and how it compares with APY with this APR Calculator.

How do you calculate Annual Percentage Rate?

To find the APR for a loan use this formula:
APR = r * p

r = Interest Rate per Period

p = Number of Periods/Year

Example: APR on a loan with a periodic interest rate of .80% and 12 periods per year. (Monthly):

r=.80

p=12

Calculated out, this gives us... .80 * 12 = 9.6%

But, we're not done yet. Many loans will advertise APR vs APY. This is Annual Percentage Yield. APR doesn't take into account the compounding nature of a loan.
In our example, you would be charged .08% interest per month. Well, the interest is charged on top of old interest. This is called compounding interest.
