Frequently Asked Questions

Will the result exactly match my bank's loan schedule?

It should closely model a conventional fixed-rate reducing-balance loan when the same principal, rate and tenure are used, but an exact match is not guaranteed. Lenders can apply product-specific dates, rounding, fees, moratorium rules and floating-rate changes.

How can I make my home loan interest-free with an SIP?

By starting a monthly equity SIP (Mutual Fund) alongside your home loan equal to 10-15% of your EMI amount (e.g. ₹4,500 SIP on a ₹30,000 EMI), the compounded returns over a 15–20 year tenure can exceed the total interest paid on the home loan, effectively creating an interest-free loan.

Which loan types can I model?

You can use the EMI model for conventional reducing-balance instalment loans such as many home, car, personal, education and business loans. Products using flat interest, irregular repayments or special moratorium structures need different treatment.

Can I calculate prepayment benefits?

Yes. The Extra Payment Analyzer shows how additional repayments can affect interest and tenure under the calculator's assumptions. Check your lender's current prepayment or foreclosure rules before acting.

Does a lower EMI always mean a cheaper loan?

No. A longer tenure can reduce the monthly EMI while increasing total interest. Processing fees and other charges also matter, so compare total borrowing cost as well as affordability.

What happens to a floating-rate EMI loan when rates change?

Depending on the lender and product, a rate reset may change the EMI, extend or shorten the tenure, or use a combination. The Interest Rate Impact Analyzer is a scenario tool rather than a prediction of the lender's future reset.
