1. What is the Monthly Interest Calculation?

The monthly interest calculation for a line of credit determines the interest payment due each month based on the outstanding principal balance and annual interest rate. This helps borrowers understand their monthly interest obligations.

2. How Does the Calculator Work?

The calculator uses the monthly interest formula:

Where:

• \( I \) — Monthly interest (currency units)
• \( P \) — Principal balance (currency units)
• \( R \) — Annual interest rate (%)

Explanation: The formula converts the annual interest rate to a monthly rate by dividing by 12, then applies it to the principal balance to calculate the monthly interest payment.

3. Importance of Monthly Interest Calculation

Details: Understanding monthly interest payments is crucial for budgeting, financial planning, and assessing the true cost of borrowing through a line of credit.

4. Using the Calculator

Tips: Enter the principal balance in currency units and the annual interest rate as a percentage. Both values must be positive numbers.
