Interest-Only Loans

In an interest-only loan, you pay only the interest for a specified period. After this period, the loan converts to a standard amortizing loan.

Interest-Only vs. Full EMI

  • Interest-Only Period: Lower initial payments
  • After IO Period: Payments increase significantly
  • Principal: Remains unchanged during IO period

Frequently Asked Questions

  • An interest-only loan lets you pay just the interest for an initial period (typically 5–10 years). During that time the principal balance doesn't reduce — you pay it down (or refinance) after the IO period ends.
  • They suit borrowers with irregular income (business owners, commission earners) or investors planning to sell/refinance before the IO period ends. They're risky for general homebuyers because total interest paid is higher.
  • Payments jump significantly because the full principal must now be amortized over the remaining tenure. Our calculator shows both the IO phase payment and the higher post-IO payment so you can plan for the shift.
  • Yes. Since the principal doesn't reduce during the IO period, interest accrues on the full balance longer. Use our EMI calculator to compare total interest for a standard amortizing loan.
