1. What is Monthly Periodic Rate?

The Monthly Periodic Rate is the interest rate applied each month, calculated by dividing the Annual Percentage Rate (APR) by 12. It represents the monthly cost of borrowing or the monthly return on investment.

2. How Does the Calculator Work?

The calculator uses the monthly rate formula:

Where:
