Loan Payment Calculator

What this calculator shows

The Loan Payment Calculator estimates the required monthly payment for a fixed-rate loan and shows how the balance is repaid over time. It also calculates the total interest and total amount paid across the life of the loan.

Why extra payments matter

Adding even a modest extra monthly payment reduces the outstanding principal sooner. That usually shortens the payoff timeline and lowers the total interest you pay, which can make a noticeable difference on long loans like mortgages and auto financing.

Good uses for this tool

• Comparing different loan terms before you borrow.
• Estimating the impact of refinancing into a lower rate.
• Testing how much faster you can pay off a mortgage with extra payments.
• Checking whether a car, equipment, or personal loan fits your monthly budget.

Important limitations

This calculator assumes a fixed annual interest rate and monthly payments for the full term. It does not include taxes, insurance, origination fees, escrow, late fees, or rate changes from adjustable products, so treat the result as a planning estimate rather than a lender quote.
