| From: | To: |
The Interest Only Mortgage Calculator calculates the monthly interest-only payment for a UK mortgage. This type of mortgage requires paying only the interest each month, with the principal amount due at the end of the loan term.
The calculator uses the interest only mortgage formula:
Where:
Explanation: The formula calculates the monthly interest payment by dividing the annual interest rate by 12 and multiplying it by the principal loan amount.
Details: Calculating interest-only payments helps borrowers understand their monthly financial commitments and plan for the eventual repayment of the principal amount at the end of the mortgage term.
Tips: Enter the principal loan amount in pounds (£) and the annual interest rate in decimal form (e.g., 0.05 for 5%). All values must be valid (principal > 0, interest rate ≥ 0).
Q1: What is an interest-only mortgage?
A: An interest-only mortgage requires the borrower to pay only the interest each month, with the principal amount due in full at the end of the loan term.
Q2: What are the advantages of interest-only mortgages?
A: Lower monthly payments compared to repayment mortgages, which can free up cash for other investments or expenses.
Q3: What are the risks of interest-only mortgages?
A: The principal amount remains unchanged, and borrowers must have a plan to repay the full principal at the end of the term, which can be challenging if investments don't perform as expected.
Q4: Are interest-only mortgages still available in the UK?
A: Yes, but they are less common and typically require a larger deposit and proof of a repayment strategy.
Q5: How is the interest rate typically expressed?
A: Interest rates are usually given as an annual percentage rate (APR), which must be converted to decimal form for calculation (e.g., 5% = 0.05).
