Frequently asked questions

Is my loan data uploaded anywhere?

No — your figures stay in your browser.

Are these the exact figures my lender will charge?

No — results are estimates. Lender fees, insurance, taxes, rounding and rate changes can alter your actual payments.

Can I download the full repayment schedule?

Yes — download the monthly amortization breakdown as a CSV file.

What does the principal-vs-interest breakdown show?

How each EMI splits between paying down the loan itself and paying interest, which typically shifts toward more principal over time.

Does it handle rate changes over the loan term?

No — it assumes a constant rate for the tenure you enter; recalculate with the new rate if your loan is variable.
