1. What is NatWest Interest Only Mortgage?

NatWest Interest Only Mortgage is a type of mortgage where you only pay the interest on the loan each month, rather than paying down the principal. The principal amount remains unchanged throughout the mortgage term.

2. How Does the Calculator Work?

The calculator uses the NatWest interest-only mortgage formula:

Where:

• \( Payment \) — Monthly payment amount (£)
• \( P \) — Principal amount (£)
• \( r \) — Annual interest rate (decimal)

Explanation: The formula calculates the monthly interest payment by dividing the annual interest rate by 12 and multiplying it by the principal amount.

4. Using the Calculator
