Amortization Calculator
Amortization Calculator
Calculate loan payments, interest costs & full amortization schedule
Monthly Payment: P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1]
Where: P = Principal | r = Monthly Rate (Annual ÷ 12) | n = Total Months
Total Interest: (Monthly Payment × n) − Principal
An amortization calculator helps you calculate your monthly loan payment, total interest and complete repayment schedule. Instead of guessing, it shows you exactly how your payments are split between principal and interest over time.
Are you thinking of taking a loan but don’t know how much you will pay every month? Do you wonder how much of your payment goes to the loan and how much goes to interest? This Loan amortization calculator can help you answer all these questions.
It shows your monthly payment, how much goes toward the loan and how much goes to interest. It can also show how extra payments can make your loan smaller faster.
But here’s the real question:
Are you paying more interest than you think? Can you reduce your total loan cost? And how do your payments change over time?
In this article, we’ll break everything down in simple terms. So, you can clearly understand your loan and make wise financial decisions.

What is an Amortization Calculator
The Amortized loan can be sorted with the use of an amortization calculator. It is an online calculator that helps you figure out your loan payments. It shows:
- Your fixed monthly payment
- How much goes toward interest
- How much reduces your loan balance
- Your remaining balance after each payment
Every loan has two parts:
- Principal: This is the money you borrowed
- Interest: This is the extra money you pay for borrowing
Most loans, like car loans, home loans, and personal loans, are paid in equal monthly payments. The calculator divides each payment into principal and interest.
Moreover, it also shows how your loan balance decreases over time. This helps you understand your loan and plan your money better.

Why You Should Use an Amortization Calculator
The main purpose of an amortization calculator is to make your loan easy to understand. It helps you:
- Know your monthly payment
- See the total interest you will pay
- Plan extra payments to reduce the loan faster
- Compare different loans to choose the best one
Using this calculator makes sure you are prepared and avoid surprises while repaying your loan.
How the Amortization Calculator Works
The calculator uses a formula to find your monthly payment and total interest.
Monthly Payment Formula
Monthly Payment = P × [r (1+r)ⁿ] ÷ [(1+r)ⁿ − 1]
where:
P = Principal (the loan amount)
r = Monthly interest rate (annual rate ÷ 12)
n = Total number of months
Total Interest Formula
Total Interest = (Monthly Payment × n) − Principal
This formula helps you see exactly how much of your payment goes to interest and how much reduces the loan.
Example to Calculate Amortization
Loan Data:
- Loan Amount: $10,000
- Interest Rate: 10% per year
- Loan Term: 5 years
- Payment Frequency: Monthly
- Compounding Frequency: Monthly
- Extra Payment: $0
Step 1: Calculate Monthly Payment
Monthly Payment = 10,000 × [0.00833(1+0.00833)^60] ÷ [(1+0.00833)^60 − 1] ≈ $212.47
Monthly Payment = $212.47
Step 2: Total Payment
Total Payment = $12,748.23
Step 3: Calculate Total Interest
Total Interest = 12,748.23 − 10,000 ≈ $2,748.23
Payoff Date = April 2031
Principal =$10.0K (78.4% of total)
Interest =$2.7K (21.6% of total)
Interest / Year = $550 (Average)
