What Is Amortization?
How loan payments are split between principal and interest over time
Amortization is the process of spreading a loan into a series of fixed payments over time. Each payment covers both interest and principal, but the ratio between them changes throughout the loan term.
In the early years of a loan, a larger portion of each payment goes toward interest. As you pay down the principal, the interest portion decreases and more of your payment goes toward the principal balance.
The cross-over point is the moment when your principal payment first exceeds the interest portion — a milestone that shows you're making significant progress on paying down your loan.
Amortization Formula & How It Works
The standard formula used to calculate fixed monthly loan payments
The monthly payment for an amortized loan is calculated using:
Step-by-step guide to generating your amortization schedule
Select a loan type
Choose from Mortgage, Auto Loan, Personal Loan, Student Loan, or enter custom values. Presets automatically fill typical defaults.
Enter your loan details
Set the loan amount, annual interest rate, and loan term in years. Adjust using the sliders or type directly.
Add extra payments (optional)
Open the "Extra Payments" section to see how additional monthly, yearly, or one-time payments reduce your total interest and payoff timeline.

Frequently Asked Questions
Common questions about amortization, loan schedules, and extra payments
An amortization schedule is a complete table showing each loan payment over the life of the loan. Each row shows how much of that payment goes toward interest, how much goes toward principal, and the remaining loan balance. Early payments are interest-heavy, while later payments are principal-heavy. This schedule helps you understand exactly where your money goes with each payment.
Amortization is calculated using the formula: M = P × [r(1+r)^n] / [(1+r)^n - 1], where M is the monthly payment, P is the principal (loan amount), r is the monthly interest rate (annual rate / 12 / 100), and n is the total number of payments (years × 12). Each month, interest is calculated on the remaining balance (Balance × Monthly Rate), and the rest of the payment reduces the principal.
Amortization and depreciation both spread costs over time, but they apply to different things. Amortization refers to paying off a loan through scheduled payments (loan amortization) or spreading the cost of an intangible asset over its useful life (accounting amortization). Depreciation is specifically about tangible physical assets losing value over time, like vehicles, equipment, or buildings.
Extra payments go directly toward reducing your principal balance. Since interest is calculated on the remaining balance each month, a lower principal means less interest in every subsequent payment. For example, adding just $200/month extra on a $250,000 mortgage at 6.5% can save you over $82,000 in interest and pay off your loan nearly 7 years early. The savings compound because each extra dollar reduces future interest charges.
The cross-over point is the first month where your principal payment exceeds the interest payment. Before this point, most of your monthly payment goes toward interest. After the cross-over, the majority goes toward building equity (reducing principal). For a 30-year mortgage at 6.5%, the cross-over typically happens around month 233 (year 20). Making extra payments moves this cross-over point earlier.
Yes, car loans are standard amortized loans. Most auto loans have fixed monthly payments calculated using the same amortization formula as mortgages. Typical auto loan terms range from 36 to 84 months (3-7 years). You can use this calculator by selecting the 'Auto Loan' preset, which sets typical defaults of $35,000 at 7.5% for 5 years, or enter your specific loan details.
Biweekly payments split your monthly payment in half and pay every two weeks. Since there are 52 weeks in a year, you make 26 half-payments, which equals 13 full monthly payments instead of 12. That one extra payment per year goes entirely toward principal, which can shave years off your loan and save thousands in interest. For a $250,000 mortgage at 6.5% over 30 years, biweekly payments can save approximately $73,000 in interest and pay off the loan about 5.8 years early.
Paying extra principal reduces your outstanding balance faster, which means you pay less interest over the life of the loan. The key benefits are: (1) You pay off the loan earlier, (2) You save significantly on total interest, (3) You build home equity faster. Most lenders allow extra principal payments without penalty, but check your loan terms for any prepayment penalties. You can use this calculator's extra payment options to see exactly how much you'd save.
