Amortization Calculator
Generate a detailed annual and monthly amortization schedule for your mortgage or loan with interactive payment summaries.
Visualize Your Loan Payoff with the Amortization Calculator
An amortization schedule is a complete table of periodic loan payments, showing the amount of principal and interest that goes into each payment until the loan is paid off in full. Our online Amortization Calculator lets you generate and compare both monthly and annual schedule views, so you can track how fast you are building equity and how your loan balance decreases over time.
Understanding Amortization Schedules
When you make a payment on an amortizing loan (like a mortgage or auto loan), the payment is split into two parts:
- Interest Payment: The fee charged by the lender for borrowing the money. In the early stages of a loan, the interest portion of your payment is at its highest because the remaining principal balance is large.
- Principal Payment: The money that directly reduces the outstanding loan balance. As the principal is paid down, the interest charged each month decreases, and a larger portion of your fixed payment goes toward principal.
Why Use an Amortization Calculator?
Generating an amortization table provides several key benefits:
- Track Equity Growth: See exactly when you will owe less than half the property value or when your loan balance drops to zero.
- Plan Extra Payments: Visualize how making additional payments toward your principal can shave months or years off your debt and save you interest.
- Tax Planning: Mortgage interest is deductible in some regions. Use the annual amortization schedule to estimate your interest payments for tax filings.
Frequently Asked Questions
What is the difference between simple interest and amortized interest?
Simple interest is calculated only on the original principal amount. Amortized interest is calculated on the remaining balance at the end of each payment period. Most home mortgages and car loans use amortization.
Why does my payment split change every month?
Although your monthly payment remains constant, the interest is computed based on your outstanding loan balance. Since the balance drops each month, the interest portion drops, allowing more of your next payment to go toward reducing the principal.
Can I see annual summaries instead of monthly details?
Yes! Our calculator offers a toggle to switch between a detailed monthly schedule and a high-level annual schedule, making it easy to see yearly totals for payments, principal, and interest.
