Frequently asked questions

Should I enter a flat or reducing rate?

The calculator uses a reducing-balance method. Confirm how the lender quotes and applies its rate.

Can I use the calculator for floating-rate loans?

You can estimate using a current rate, but future rate changes will alter the schedule.

Why might a lender show a different EMI?

Differences can come from payment dates, rounding, fees, rate conventions, or product terms.
