How an EMI splits over a 20-year loan
Amber is interest, mint is principal. The exact split depends on rate and tenure.
One payment, two parts
An EMI, or a mortgage payment, is a fixed monthly amount that combines interest and principal. Early on most of it is interest. The split flips over time, which is why the balance barely moves in the first years and then falls quickly at the end.
Tenure is a trade
A longer tenure lowers the monthly payment but raises the total interest dramatically. A 20-year loan can cost more in interest than the amount you borrowed. Grownz's Housing screen shows the interest and principal split of each month so the trade is visible, not hidden in a rate.
Prepay early, not late
Prepaying even small amounts early cuts total interest sharply, because you remove principal while interest is at its peak. The same amount prepaid in year 15 does far less. The Prepayment Lab on Housing and Loans shows the exact effect: the interest removed and the months taken off.
Compare the APR
Before signing, compare the APR, the true cost including fees, not just the advertised rate. Two loans with the same headline rate can differ by thousands over the term.
Fixed, floating and the reset
A floating rate follows the market and your EMI or tenure resets when it moves. A fixed rate holds for a period and then resets too. Know which you have and when the reset is; Grownz's reminders can hold the date.
