The PMT function in Excel determines the total payment owed each period—inclusive of the interest and principal payment. The total payment, unlike the other two components, will remain constant over the entire borrowing term.
For example, if you borrow Rs. 10,000 at an annual interest rate of 6% for 3 years (36 months), the monthly EMI would be EMI = 10,000 (0.06/12) (1 + 0.06/12)^36 / ((1 + 0.06/12)^36 - 1) = Rs. 303.87.
Fortunately, Excel can be used to create an amortization schedule. The amortization schedule template below can be used for a variable number of periods, as well as extra payments and variable interest rates.
