Fixed vs floating interest rates

How fixed and floating rates work, and the questions to ask before you choose.

When you take a loan, the interest rate may be fixed or floating. The choice affects how predictable your repayments are.

Fixed rates

A fixed rate stays the same for an agreed period, so your EMI is predictable. Some loans are fixed only for an initial period and then become floating.

Floating rates

A floating rate is linked to a benchmark and can move up or down over the life of the loan. When rates change, lenders may adjust your EMI, your tenure or both.

Questions to ask your lender

  • Which benchmark is the rate linked to, and how often is it reset?
  • If rates rise, will the EMI or the tenure change?
  • Are there charges for switching between fixed and floating?
  • What are the prepayment terms?

Our calculators assume a fixed rate for the whole tenure, which makes them useful for comparison but not a prediction of future rates.
