About Loan Calculator
Before you borrow, it helps to know what the loan will really cost. This calculator takes the loan amount, the yearly interest rate and the length of the loan in years, and shows your monthly payment, the total you will repay, and the total interest. It starts with an example: borrowing 10,000 at 5% over 5 years gives a monthly payment of 188.71, a total repaid of 11,322.74 and total interest of 1,322.74.
It uses the standard formula for a loan with equal monthly payments and a fixed interest rate. The yearly rate is divided by 12 and applied each month, and the monthly payment is set so that the loan is paid off exactly at the end of the term. Total payment is the monthly payment times the number of months, and total interest is total payment minus the amount you borrowed. A longer term lowers the monthly payment but raises the total interest, so try different terms to see the trade-off.
Below the result is a year-by-year amortization table. For each year it shows the payments made, how much of that was interest, how much reduced the amount you owe, and the balance left at the end of the year. Early payments are mostly interest, and the share that repays the loan grows over time. A 0% rate works too, and then the payment is simply the loan divided by the number of months. Some limits remain. The result does not include arrangement fees, insurance, taxes or late-payment charges, and it does not model extra repayments or a changing rate. The table is yearly, not month by month. Your lender's official figures are the ones that count, so use this to compare options and confirm the details with them.

Frequently asked questions
How is the monthly payment calculated?
It uses the standard loan formula for equal monthly payments at a fixed rate. The yearly rate is divided by 12 and applied each month, so the loan is paid off exactly at the end of the term.
What is total interest?
It is the total you repay minus the amount you borrowed. It is the cost of borrowing.
Why does a longer term cost more in total?
The monthly payment is lower, but interest is charged for more months, so the total interest is higher.
What is amortization?
It is the way a loan is repaid in equal instalments so that each payment covers the interest for that period and the rest reduces the amount you owe. The table shows this year by year.
Why does it ask me to check my numbers?
The loan amount must be above zero, the interest rate zero or more, and the term must be a valid number of years. Anything else shows a message instead of a result.
Does it include fees or insurance?
No. It covers the loan amount and interest only. Fees, insurance, taxes and late charges are not included.
Does it handle extra payments or a changing rate?
No. It assumes equal monthly payments and a fixed rate for the whole term, so it does not model extra repayments or an adjustable rate.
Is my information stored?
