The Annual Percentage Rate (APR) is a key figure when it comes to understanding the cost of borrowing money. It reflects the yearly cost of funds over the term of a loan or credit, expressed as a percentage. In this calculator, we focus on how to calculate the APR based on a given monthly interest rate over a specified number of months.

### Formula

To calculate APR based on the monthly interest rate, the formula is:

APR = Monthly Interest Rate (r) × Number of Months (n)

Where:

**r**is the monthly interest rate in percentage.**n**is the number of months in a year (usually 12).

### How to Use

To use the APR Per Month Calculator:

- Enter the monthly interest rate (r) in percentage form.
- Enter the number of months (n) for which you want to calculate the APR.
- Click the

### Example

If you have a loan with a monthly interest rate of 1.5% and want to know the APR over 12 months, you would use the formula:

APR = 1.5% × 12 = 18%

Thus, the APR for this loan would be 18%.
