Key Excel functions (PMT, PPMT, IPMT) are used to calculate total payments, principal, and interest for each period in an amortization schedule.
The formula to be used will be =IPMT( 5%/12, 1, 60, 50000). In the example above: As the payments are made monthly, it was necessary to convert the annual interest rate of 5% into a monthly rate (=5%/12), and the number of periods from years to months (=512).
Even a single extra payment made each year can reduce the amount of interest and shorten the amortization, as long as the payment goes toward the principal and not the interest.
If you prepay your mortgage you reduce the principal balance, reducing the interest due next month and every month forward. If you prepay $1000 on your mortgage, the interest next month will be reduced by 10003.7%/12=3.08 You will still make the same payment, but an additional 3.083 will be credited toward principal.
Ideally, you want your extra payments to go towards the principal amount. However, many lenders will apply the extra payments to any interest accrued since your last payment and then apply anything left over to the principal amount. Other times, lenders may apply extra funds to next month's payment.
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.
