How to Use This Tool
Step-by-step guide to get the best results
1

Enter the Loan Amount

Type the total amount you plan to borrow, excluding any down payment or fees you will pay upfront.

2

Set the Interest Rate

Input the annual percentage rate (APR) for the loan. Use the rate your lender quoted or compare different offers.

3

Choose the Loan Term

Select the repayment period in months or years. Longer terms mean lower monthly payments but more total interest.

4

Review the Results

Check your monthly payment, total interest, total cost, and the full amortization schedule with principal and interest breakdowns.

Pro Tips
1

A shorter loan term increases your monthly payment but can save thousands in interest over the life of the loan.

2

Always compare the APR rather than just the interest rate, as APR includes fees and gives a true cost picture.

3

Making one extra payment per year can shave years off a long-term loan and reduce total interest significantly.

4

Check whether your loan has a prepayment penalty before planning early payoff strategies.

Frequently Asked Questions
How is the monthly payment calculated?

The monthly payment is computed using the standard amortization formula that divides the principal by the number of payments and adds the interest accrued on the remaining balance each period. This produces a fixed payment amount that stays the same throughout the loan.

What is an amortization schedule?

An amortization schedule is a table showing each payment over the life of the loan. It lists how much of each payment goes toward principal, how much goes toward interest, and the remaining balance after each payment.

Can I use this for variable-rate loans?

This calculator is designed for fixed-rate loans where the interest rate stays constant. For variable-rate loans, you would need to recalculate whenever the rate changes.

What is the difference between APR and interest rate?

The interest rate is the cost of borrowing the principal amount. APR includes the interest rate plus lender fees, points, and other charges, giving a more complete picture of the loan cost.

How do extra payments affect my loan?

Extra payments go directly toward the principal balance, which reduces the amount of interest accrued on future payments. This shortens the loan term and lowers the total interest paid over the life of the loan.
