How is each EMI split between interest and principal?
Each month the tool charges interest on the balance you still owe, at the annual rate divided by 12, and the rest of the fixed EMI reduces the loan. The EMI itself comes from the standard reducing-balance formula: EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where P is the loan amount, r the monthly rate and n the number of months.
With the default ₹25 lakh at 8.5% for 20 years, the EMI is ₹21,696. In month 1, interest takes ₹17,708 (₹25,00,000 × 8.5% ÷ 12) and only ₹3,987 goes to principal. Over the first year you pay ₹2,10,591 in interest against ₹49,756 of principal, leaving ₹24,50,244 outstanding. Halfway through, after 120 EMIs worth ₹26,03,470, the balance is still ₹17,49,846, so only about 30% of the loan has been repaid. Year 13 is the first in which principal (₹1,37,487) exceeds interest (₹1,22,860).
How much extra interest does a longer tenure cost?
Stretching the tenure lowers the EMI slowly and raises total interest quickly. Keeping ₹25 lakh at 8.5%, a 15-year loan has an EMI of ₹24,618 and total interest of ₹19,31,328. Moving to 20 years cuts the EMI by ₹2,923 and adds ₹7,75,611 of interest. At 30 years the EMI is ₹19,223 and interest reaches ₹44,20,221, about 1.77 times the amount borrowed. Drag the tenure slider and watch the Total interest payable card to see the same trade-off for your own loan.
Why might your lender's schedule look different?
The schedule assumes one fixed rate for the whole term, an EMI from the first month and no prepayments. A floating-rate loan that gets repriced, or a part-prepayment, changes every row after that month. To approximate the new position, enter the outstanding balance, the new rate and the years left. Because the sliders move in steps of ₹10,000 and whole years, treat that rerun as an approximation.
The table groups payments by loan year: year 1 means your first 12 EMIs, whichever month they began in, so the figures will not match a statement that covers an April to March financial year. Internally the EMI is kept unrounded and only the display is rounded, so a lender's schedule that rounds the EMI to the rupee will drift slightly from these figures, with the gap growing toward the end of the term. Slider ranges are ₹50,000 to ₹2 crore, 4% to 20% and 1 to 30 years. For figures outside those ranges, or when you only need the EMI, the EMI Calculator accepts typed values.
