Interest Only Mortgage Formula:
| From: | To: |
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 which they must start paying both principal and interest. This results in lower initial payments but requires careful financial planning.
The calculator uses the interest-only mortgage formula:
Where:
Explanation: The formula calculates only the interest portion of the mortgage payment, which remains constant during the interest-only period as the principal balance doesn't decrease.
Details: Calculating interest-only payments helps borrowers understand their short-term financial obligations and plan for the transition to full principal and interest payments. It's crucial for budgeting and assessing affordability over the loan term.
Tips: Enter the principal amount in currency units and the annual interest rate as a percentage. Both values must be positive numbers to calculate a valid monthly payment.
Q1: What are the advantages of interest-only mortgages?
A: Lower initial payments, improved cash flow in the short term, and potential tax benefits (consult a tax advisor).
Q2: What are the risks of interest-only mortgages?
A: Principal balance doesn't decrease during interest-only period, potential for payment shock when principal payments begin, and risk of negative equity if property values decline.
Q3: Who should consider interest-only mortgages?
A: Borrowers with irregular income, those expecting significant future earnings increases, or investors who plan to sell the property before the interest-only period ends.
Q4: How long do interest-only periods typically last?
A: Most interest-only periods range from 5-10 years, after which the loan converts to a fully amortizing mortgage.
Q5: Can I make principal payments during the interest-only period?
A: Most lenders allow optional principal payments during the interest-only period, but check with your specific lender for terms and conditions.
