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).
Example of Amortization In the first month, $75 of the $664.03 monthly payment goes to interest. The remaining $589.03 goes toward the principal. The total payment stays the same each month, while the portion going to principal increases and the portion going to interest decreases.
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.
Use the PMT function in Excel to create the formula: PMT(rate, nper, pv, fv, type). 1 This formula lets you calculate monthly payments when you divide the annual interest rate by 12, for the number of months in a year.
Open the Schedule template in Google Sheets At the top of the page, you'll see a section called “Start a new spreadsheet” with several different options to choose from. From here, you'll click “Template gallery” at the top right-hand corner of this section.
You can ask your lender for an amortization schedule, but this might not be as helpful if you're looking to see how extra payments could impact that schedule.
