Interest Only Payment Formula:
| From: | To: |
Interest-only payment is a mortgage payment structure where the borrower pays only the interest on the loan principal for a specified period, with the principal amount remaining unchanged. This is commonly used in buy-to-let (BTL) mortgages.
The calculator uses the interest-only payment formula:
Where:
Explanation: The calculation multiplies the principal amount by the monthly interest rate to determine the interest-only payment amount.
Details: Accurate interest-only payment calculation is crucial for buy-to-let investors to understand their monthly cash flow obligations, assess rental yield viability, and make informed investment decisions.
Tips: Enter the principal amount in currency and the monthly interest rate as a decimal (e.g., 0.005 for 0.5%). Both values must be valid (principal > 0, interest rate between 0-1).
Q1: What is the advantage of interest-only mortgages?
A: Interest-only mortgages typically have lower monthly payments initially, which can improve cash flow for investors and allow for potential investment of the saved funds elsewhere.
Q2: How do I convert annual interest rate to monthly?
A: Divide the annual interest rate by 12. For example, 6% annual rate = 0.06/12 = 0.005 monthly rate.
Q3: Are there risks with interest-only mortgages?
A: Yes, the principal amount remains unchanged, and you'll need to repay the full principal at the end of the term or refinance, which carries risks if property values decline.
Q4: Who typically uses interest-only mortgages?
A: Primarily buy-to-let investors, property developers, and sometimes high-net-worth individuals who have alternative investment strategies.
Q5: Can I switch from interest-only to repayment?
A: Many lenders allow switching, but this will increase your monthly payments as you'll be paying both interest and principal.
