1. What is an Interest-Only Mortgage?

An interest-only mortgage is a type of loan where the borrower pays only the interest for a set period, typically 5-10 years. After this period, payments increase to include both principal and interest. This calculator helps estimate monthly payments during the interest-only period.

2. How Does the Calculator Work?

The calculator uses the interest-only mortgage formula:

Where:

• \( P \) — Principal loan amount (currency units)
• \( R \) — Annual interest rate (%)

Explanation: The formula calculates the monthly interest payment based on the principal amount and annual interest rate, divided by 12 months.

3. Importance of Interest-Only Mortgage Calculation

Details: Accurate monthly payment calculation is crucial for retirement planning, budgeting, and understanding the financial commitment of an interest-only mortgage. It helps borrowers assess affordability during the interest-only period.

4. Using the Calculator

Tips: Enter the principal amount in currency units and the annual interest rate as a percentage. Both values must be valid (principal > 0, interest rate ≥ 0).
