Backend Formula for the Interest Only Monthly Payment Calculator
The formula for calculating interest-only payments is straightforward:
Monthly Interest Payment = (Loan Amount * Interest Rate) / 12
Here’s an illustrative example: For a $200,000 loan at an annual interest rate of 6%, the monthly interest payment would be calculated as (200,000 * 0.06) / 12, which equals $1,000.
While alternative methods exist, such as using different compounding periods, this formula is chosen for its simplicity and accuracy in calculating straightforward interest-only payments.

Follow these detailed steps to manually calculate interest-only payments:
- Determine the Loan Amount: This is the principal sum borrowed.
- Identify the Annual Interest Rate: Convert this into a decimal for calculation purposes.

Example 1: For a $150,000 loan at 4%, the monthly payment is (150,000 * 0.04) / 12 = $500.
Example 2: A $250,000 loan at 3.5% results in a monthly interest payment of (250,000 * 0.035) / 12 = $729.17.
