How this works
This is the plain reducing-balance EMI formula used for any type of loan — enter the amount, annual rate and tenure, and it solves directly for the fixed monthly installment, without needing every other field a specific loan type (mortgage, car) would ask for.
Common questions
Is this the same math banks actually use?
Yes — reducing-balance EMI is the standard method almost all banks and NBFCs use for personal, auto and home loans. The formula is public; what varies is the rate and fees a specific lender charges.
Why does a longer tenure lower the EMI but cost more overall?
Because you're paying interest on the balance for more months — the reducing-balance formula means a lower monthly figure but a higher total interest paid over a longer term, for the same rate.
