What the Loan Calculator does

This Loan Calculator estimates the fixed monthly payment for a loan based on three inputs: the amount borrowed, the annual interest rate, and the loan term. It also shows the total amount you will repay over the life of the loan, the total interest cost, and the original principal, so you can see at a glance how much borrowing actually costs.

It suits anyone weighing up a personal loan, car finance, a mortgage, or any other instalment loan with a fixed rate. Comparing a few scenarios side by side makes it easy to understand how the rate and term affect both your monthly budget and the total interest you pay.

How to use it

Enter the loan amount, the annual interest rate as a percentage, and the loan term. You can express the term in either years or months using the dropdown, and the calculator converts it internally for you.

The monthly payment and summary figures update immediately. Below them, an amortization schedule lists the first twelve months of payments, breaking each one into the portion that goes toward interest and the portion that reduces your balance, along with the remaining balance after each payment.

How the numbers are calculated

The monthly payment uses the standard amortizing-loan formula, which converts the annual rate into a monthly rate and spreads repayment evenly across every month of the term. If you enter a zero percent rate, the calculator simply divides the principal evenly across the months.

Early in the schedule a larger share of each payment goes to interest, and over time more goes to principal. This is why the interest column shrinks month by month in the table. The results are estimates for a fixed-rate loan and do not include fees, insurance, or taxes that a particular lender may add.

Frequently Asked Questions

How is the monthly payment calculated?▼
It uses the standard amortizing-loan formula, converting the annual interest rate to a monthly rate and dividing repayment evenly across the full term. If the rate is zero, the principal is simply split equally across the months.
Can I enter the term in months instead of years?▼
Yes. Use the dropdown next to the term field to switch between years and months. The calculator converts your entry to months internally for the math.
What is the amortization schedule?▼
It is a month-by-month breakdown of your payments showing how much goes to interest, how much reduces the principal, and the remaining balance. This tool displays the first twelve months.
Does the result include fees or insurance?▼
No. The figures cover principal and interest only. Lender fees, insurance, and taxes vary by provider and are not included, so treat the result as an estimate.
Is the calculator free and private?▼
Yes. It is free to use and runs entirely in your browser, so the loan details you enter are never sent to any server.
