Understanding Loan Amortization
Loan amortization is the process of paying off a loan through regular payments, which typically include both interest and principal. The goal of loan amortization is to reduce the outstanding principal balance over time, eventually paying off the loan in full. To create a simple loan amortization schedule in Excel, you need to understand the following key components:- Loan amount: The initial amount borrowed
- Interest rate: The rate at which interest is charged on the loan
- Loan term: The length of time the loan is outstanding
- Monthly payment: The regular payment made towards the loan
Setting Up Your Excel Spreadsheet
- Period: The month or payment number
- Beginning Balance: The outstanding principal balance at the beginning of each period
- Interest: The interest charged on the loan for each period
- Payment: The monthly payment made towards the loan
- Principal: The principal paid during each period
- Ending Balance: The outstanding principal balance at the end of each period
Calculating Loan Amortization

| 2 | $9,000 | $75.00 | $1,083.33 | $1,008.33 | $7,991.67 |
| 3 | $7,991.67 | $66.66 | $1,083.33 | $1,016.67 | $6,974.99 |
