Whether you’re taking out a mortgage, car loan, or personal loan, this tool makes amortization simple, transparent, and easy to manage.
What Is an Amortization Schedule?
An amortization schedule is a table of loan payments over time, detailing:
- Total payment amount per period (usually monthly)
- Portion of the payment going to interest
- Portion going to principal
- Remaining loan balance after each payment
It allows borrowers to see how their loan decreases over time and how interest accumulates.
How Does an Amortization Schedule Work?
Loans are typically paid in equal installments, but the interest and principal portions change over time:
- Early payments → mostly interest, small principal
- Later payments → mostly principal, less interest
The schedule ensures full repayment by the end of the loan term.

The calculator produces a detailed schedule showing each payment, interest, principal, and remaining balance.
Amortization Formula Overview
The monthly payment can be calculated using the formula:
M = P * r * (1 + r)^n / ((1 + r)^n - 1)Where:
- M = monthly payment
- P = principal loan amount
- r = monthly interest rate (annual rate ÷ 12)
- n = total number of payments (years × 12)
The amortization schedule breaks M into principal and interest components for every payment.
Step-by-Step Example
Suppose:
- Loan: $10,000
- Annual Interest Rate: 5%
- Term: 2 years
- Payment: Monthly
Monthly Payment Calculation:
r = 0.05 / 12 = 0.004167 n = 2 * 12 = 24 M = 10,000 * 0.004167 * (1 + 0.004167)^24 / ((1 + 0.004167)^24 - 1) ≈ 438.71 First Month:
- Interest: $10,000 × 0.004167 = $41.67
- Principal: $438.71 − $41.67 = $397.04
- Remaining Balance: $10,000 − $397.04 = $9,602.96
The schedule continues similarly until the loan is paid off.

Common Questions About Amortization
Can I prepay a loan with an amortization schedule?
Yes. The schedule can be adjusted to show reduced interest and shorter term if extra payments are made.
Is the monthly payment always the same?
Yes, for standard loans with fixed interest rates. Variable rates can change the payment.
How does amortization affect interest paid?
More frequent payments or early principal repayment reduces total interest over the life of the loan.
Can I use it for any type of loan?
Yes. The calculator works for personal, auto, mortgage, and student loans.
