Payment Breakdown
How to Use the Loan Calculator
- 1
Enter Your Loan Amount
Type the total amount you plan to borrow into the Loan Amount field. This is the principal balance before any interest is applied. Include only the financed portion -- exclude any down payment you have already made. - 2
Set the Interest Rate
Enter the annual interest rate offered by your lender. Even a small difference in rate can significantly change your total cost. If you have quotes from multiple lenders, run each one separately to compare. - 3
Choose the Loan Term
Select how many years you plan to repay the loan. Common terms are 3, 5, 10, 15, 20, or 30 years. Shorter terms mean higher monthly payments but less total interest paid over the life of the loan. - 4
Review Results and Amortization
The calculator instantly displays your monthly payment, total interest, and total cost. Open the amortization schedule to see exactly how each payment is split between principal and interest month by month.

Why use a Loan Calculator?
A loan calculator is the single most important tool to use before signing any borrowing agreement. By entering your loan amount, annual interest rate, and repayment term, you get an instant breakdown of your monthly payment, total interest charges, and cumulative cost. Whether you are financing a home, a car, higher education, or a personal expense, understanding these numbers puts you in control of the decision rather than relying on a lender's estimate alone.
The amortization schedule is where the real insight lives. It shows you, month by month, how each payment is divided between principal reduction and interest. In the early years of most loans, the majority of every payment goes toward interest. As the balance shrinks, more of each payment chips away at the principal. Seeing this progression helps you evaluate whether refinancing or making extra payments could save you money. You can also compare results with the Amortization Calculator for an even more detailed payment schedule.
For broader financial planning, pair this calculator with the Debt Payoff Calculator to build a strategy for eliminating multiple debts, or use the Compound Interest Calculator to see how investing the money you save on interest could grow over time. All calculations run entirely in your browser -- nothing is uploaded to a server -- so your financial data stays private.
How It Compares
Choosing between loan offers comes down to three variables: interest rate, term length, and total cost. A lower rate obviously reduces your monthly payment, but extending the term from 15 to 30 years can double the total interest paid even at the same rate. For example, a $250,000 loan at 6.5% costs about $1,580 per month over 30 years with roughly $319,000 in total interest, while the same loan over 15 years costs about $2,177 per month but only $142,000 in total interest -- a savings of $177,000.
Fixed-rate loans offer predictable payments for the entire term, making budgeting straightforward. Variable-rate loans start lower but can increase over time, adding uncertainty. Use this calculator to model both scenarios and decide which structure fits your risk tolerance and monthly budget. If you are specifically shopping for a home, the Mortgage Calculator and Home Affordability Calculator provide additional property-specific inputs like taxes and insurance.
