Is my data uploaded anywhere?
No. The reducing-balance math runs entirely in your browser — the page makes no network requests with your figures. You can verify this in your browser's developer tools or disconnect from the network after the page loads.
Which formula does it use?
The standard reducing-balance EMI banks quote: EMI = P·r·(1+r)ⁿ/((1+r)ⁿ−1) with monthly r. Identical inputs give identical EMIs to your bank's calculator; small differences come from their rounding or fee inclusion.
Why is early EMI almost all interest?
Interest each month is charged on the outstanding balance, which is largest at the start. Prepayments early in the tenure therefore destroy far more interest than equal prepayments later — the schedule table shows exactly why.
Does it handle flat-rate or teaser loans?
No — flat-rate schemes quote interest on the original principal every month, which understates the true cost versus reducing balance. Convert the offer to its reducing-balance equivalent rate before comparing here.
Is this financial advice?
No. It is arithmetic for planning and comparison — fees, insurance, taxes and prepayment penalties sit outside it. Confirm borrowing decisions with a qualified adviser.
