Interest-Only Loan Calculator
Calculate the monthly cost of an interest-only loan and the principal still owed afterward.
About this calculator
With an interest-only loan you pay just the interest for a set period; the principal stays unchanged and is due later.
These keep early payments low but cost more overall since the principal isn't reducing.
All calculations happen in your browser — your numbers are never sent anywhere. Results are estimates for guidance only, not financial advice.
Frequently asked questions
When are interest-only loans used?
For bridge financing, construction, or when borrowers expect higher income later.
Is the principal ever repaid?
Yes — after the interest-only period you must repay the full principal, often via a lump sum or a converted EMI.
