How to Use the Loan Calculator

Our free loan calculator helps you determine monthly payments, total interest costs, and create amortization schedules for any type of loan. Follow this guide to make the most of our calculator.

Step-by-Step Instructions

1 Enter Your Loan Amount

Input the total amount you want to borrow. This is the principal amount of your loan, excluding any fees or interest. For example, if you're buying a $200,000 home with a $40,000 down payment, enter $160,000.

2 Set the Interest Rate

Enter the annual interest rate (APR) for your loan. This should be the rate quoted by your lender. Don't include the % symbol - just enter the number. For example, for a 5.5% rate, enter 5.5.

3 Choose Your Loan Term

Select how long you'll take to repay the loan. You can enter this in years or months. Common terms are 15 or 30 years for mortgages, 5-7 years for auto loans, and 2-5 years for personal loans.

4 Select Your Currency (Optional)

Choose your preferred currency from the dropdown menu. The calculator supports multiple currencies including USD, EUR, GBP, and more. This only affects the display format, not the calculations.

5 View Your Results

The calculator instantly shows your monthly payment amount, total interest paid over the loan term, and total amount you'll repay. A visual chart displays the principal vs. interest breakdown.

Total Interest

The total amount of interest you'll pay over the entire loan term. This shows the true cost of borrowing.

Total Payment

The sum of your loan amount (principal) plus all interest payments. This is the total amount you'll have paid by the end of the loan.

Frequently Asked Questions

Q: Is this calculator accurate?

A: Yes, our calculator uses the standard amortization formula used by banks and lenders. However, your actual payment may vary slightly due to fees, taxes, or insurance not included in the basic calculation.

Q: What's not included in the calculation?

A: The calculator shows principal and interest only. For mortgages, you'll also need to budget for property taxes, homeowners insurance, HOA fees, and possibly PMI. For auto loans, consider insurance and maintenance.

Q: Can I save my calculations?

A: Yes! You can download a PDF report of your calculation, print the results, or share them via email or social media using the buttons below the results.

Q: Why does most of my payment go to interest at first?

A: This is how amortization works. Early in the loan, you owe more principal, so more interest accrues. As you pay down the principal, less interest accrues, so more of your payment goes to principal.

Q: Should I choose a longer or shorter loan term?

A: Shorter terms have higher monthly payments but save significant interest. Longer terms have lower payments but cost more overall. Choose based on your monthly budget and long-term financial goals.
