When you borrow money to buy a home, you agree to pay it back in small steps over many years. This step-by-step repayment is called amortization. A mortgage amortization calculator shows you how those payments are divided between principal (the amount you borrowed) and interest (the fee charged by the bank).
At first, most of your monthly payment goes toward interest. Over time, as the balance goes down, more of your payment goes toward the principal. By looking at an amortization schedule, you can see exactly how much you will pay each month, how long it will take to finish the loan, and how much interest you will pay in total.
Our free calculator lets you enter your loan amount, interest rate, loan term, and optional costs like property taxes or insurance. With just one click, you can view your monthly payment, a mortgage amortization chart, and a table calculator that breaks down every payment until your loan is fully repaid.
How to Use the Loan Amortization Calculator
Using this tool is very simple:
- Enter the home price and your down payment. The loan amount will calculate automatically.
- Type in the loan term (for example, 15 years, 20 years, or 30 years).
- Add the annual interest rate given by your bank.
- (Optional) Enter annual property taxes, insurance, or monthly HOA fees.
- Click calculate and instantly see your monthly payment, amortization schedule, and total loan cost.
This calculator is useful before you meet a lender. It gives you the power to test different scenarios. You can check how payments change with shorter loan terms or how much money you save by making extra principal payments.
Why Amortization Matters
Many home buyers only focus on the monthly payment. It feels simple: if I can afford the monthly payment, I can afford the house. But the truth is more complicated.
In a 30-year loan, you may end up paying almost double the amount you borrowed once you add interest. That’s the hidden cost of long-term borrowing. By studying an amortization chart, you see the big picture instead of just the small monthly number.
This matters because:
- You know the real cost of your loan.
- You see how much of your payment is lost to interest in the early years.
- You can compare a 15-year loan vs a 30-year loan and make smarter choices.
- You can plan extra payments to save thousands in interest.
Save Money With Extra Payments
One of the best features of this calculator is that it allows you to test what happens when you make extra principal payments.
Suppose you borrow $240,000 at 6% interest for 30 years. Your monthly payment for principal and interest is about $1,439. Over 30 years, you will pay $518,400 in total, which includes $278,400 in interest.
Now add an extra $200 each month toward the principal:
- The loan finishes in about 24 years instead of 30.
- You save almost $54,000 in interest.
This shows the power of small extra payments. You don’t have to double your payment. Even a little extra money shortens the loan term and keeps thousands in your pocket.

Early Repayment Benefits
People often ask: should I pay off my mortgage early? The answer depends on your financial goals, but the calculator makes the benefits clear.
By choosing a shorter loan term — say 15 years instead of 30 — you pay higher monthly amounts but much less interest overall. For example:
- $240,000 loan at 6% for 30 years → monthly $1,439, total interest $278,400.
- $240,000 loan at 6% for 15 years → monthly $2,029, total interest $126,120.
That’s a saving of over $150,000 just by going for a shorter term.
Our mortgage repayment early calculator helps you see exactly how much you save if you increase your monthly payments or shorten the loan duration.
Loan/ Mortgage Amortization Chart and Table
Numbers are easier to understand when you can see them visually. That’s why our calculator gives you both a mortgage amortization chart and a table calculator.
- The chart shows how your balance decreases over time. You’ll see a curve that starts flat but bends downward as more of your payment goes to principal.
- The table lists every monthly payment. For each row, you’ll see:
- How much goes to interest
- How much goes to principal
- The remaining balance
This makes it crystal clear how your loan is moving. Instead of just trusting the bank, you can watch every dollar at work.
Example Walkthrough
Let’s walk through a real-life example with our calculator:
- Home Price: $300,000
- Down Payment: $60,000
- Loan Amount: $240,000
- Loan Term: 30 years
- Interest Rate: 6%
- Property Taxes: $3,000 per year
- Insurance: $1,200 per year
- HOA: $50 per month
Results:
- Monthly principal and interest: $1,439
- Taxes, insurance, HOA: $350
- Total monthly payment (PITI): $1,789
- Total loan cost over 30 years: $518,400
- Interest paid: $278,400
This is why knowing amortization is so powerful. The house looks like it costs $300,000, but in reality, with interest and other costs, it is much higher.
FAQs
Q: What does amortization mean?
Amortization means paying off a loan gradually over time with equal monthly payments. Each payment includes both interest and principal.
Q: Can I pay off my loan early without penalty?
Many lenders allow this, but some charge a prepayment penalty. Always check your loan agreement.
Q: Why is most of my payment interest in the beginning?
Because interest is charged on the full balance. As the balance decreases, the interest portion also decreases.
Q: How often should I use this calculator?
Anytime you are thinking about buying a home, refinancing, or making extra payments. It helps you see the effect before making decisions.
