How to Find Monthly Percentage Rate

April 24, 2025 3 min read

Understanding interest rates is crucial for making informed financial decisions, whether you're taking out a loan or investing your savings. While interest rates are often quoted as an annual percentage (Annual Percentage Rate, or APR), it's often more helpful to know the monthly percentage rate. This is the interest you're charged or earn each month.

Why Calculate Monthly Percentage Rate?

  • Budgeting: Knowing your monthly percentage rate helps you accurately calculate your monthly interest payments on loans, making budgeting easier.
  • Comparison: Comparing different loan or investment options becomes simpler when you understand the monthly implications of the annual rate.
  • Understanding Growth: For investments, the monthly rate shows you how much your investment is growing each month, aiding in tracking progress and making adjustments.

Calculating the Monthly Percentage Rate

Here's how to convert an annual percentage rate (APR) to a monthly percentage rate:

  1. Convert APR to Decimal: Divide the APR by 100. For example, if your APR is 6%, then 6 / 100 = 0.06.
  2. Divide by 12: Divide the decimal by 12 (the number of months in a year). So, 0.06 / 12 = 0.005.
  3. Convert back to Percentage: Multiply the result by 100. Thus, 0.005 * 100 = 0.5%.

Therefore, an APR of 6% equals a monthly percentage rate of 0.5%.

Example: Calculating Monthly Interest on a Loan

Let’s say you have a loan of $10,000 with an APR of 6%. To find out how much interest you pay each month, use these steps:

  1. Calculate the monthly percentage rate: 6% APR / 12 months = 0.5% per month.
  2. Multiply the loan amount by the monthly percentage rate: $10,000 * 0.005 = $50.

Therefore, your monthly interest payment would be $50.

Understanding APY vs. APR

It's important to distinguish between APR (Annual Percentage Rate) and APY (Annual Percentage Yield). APR is the simple annual interest rate, while APY takes into account the effect of compounding. APY will always be higher than APR if interest is compounded more than once a year. When calculating monthly interest, it's generally best to start with the APR to get a clearer picture of the periodic interest rate.
