Payment Calculator
Calculate fixed monthly payments for any loan amount, interest rate, and term.
How this is calculated
Payment = PV × r / (1 − (1 + r)^−n), where r = monthly rate, n = months
Frequently Asked Questions About Payment Calculator
A payment calculator helps you determine fixed monthly loan payments based on loan amount, interest rate, and term length. Use it to budget and compare different loan terms before borrowing.
How is the monthly payment calculated?
The monthly payment is calculated using the standard loan amortization formula that factors in the principal amount, monthly interest rate, and total number of payments. This formula ensures equal payments throughout the loan term, with early payments going mostly to interest and later payments to principal.
Why does a shorter loan term result in higher monthly payments?
With a shorter loan term, you're repaying the same borrowed amount over fewer months, which means each payment must be larger. However, shorter terms result in significantly lower total interest paid over the life of the loan.
What is the relationship between interest rate and monthly payment?
A higher interest rate increases your monthly payment proportionally. For example, increasing the rate from 5% to 7% raises not just the interest portion but also the total amount you pay each month, making the loan more expensive overall.
Can I pay more than the calculated monthly payment?
Yes, most loans allow additional principal payments without penalty. Paying more than the minimum reduces your loan balance faster, which saves you interest and shortens the loan term.
How much of my payment goes to principal vs interest?
Early in the loan, most of your payment covers interest, while less goes to principal. As you progress through the loan, this ratio reverses. This calculator shows the principal percentage to help you understand your payment breakdown.
Should I choose a shorter or longer loan term?
Shorter terms save you money on total interest but require higher monthly payments. Longer terms lower monthly payments but cost more overall. Choose based on your budget and how much total interest you're willing to pay.
