Loan Calculator for Monthly Payments
Estimate fixed loan payments, total interest, total cost, and how extra monthly payments could change payoff time.
A loan calculator estimates monthly payments from principal, annual interest rate, and loan term.
Extra monthly payments can reduce payoff time and total interest when applied to principal.
Use financed amount
Include fees or taxes only if they are rolled into the amount being borrowed.
Match the quoted APR context
Actual lender quotes may include fees, insurance, penalties, and other rules.
Example
A $25,000 loan at 7.5% over 5 years creates a predictable monthly payment estimate.
Assumption
Interest is compounded monthly and payments are made monthly.
Limitation
Actual loans can include fees, insurance, taxes, penalties, and lender-specific rules.
Personal loans
Estimate monthly cost and total interest for fixed-rate borrowing.
Auto loans
Compare amount, rate, and term scenarios before shopping.
Extra payments
Check how added monthly principal payments may shorten payoff time.
Budget planning
Estimate whether a payment fits your monthly cash-flow target.
Can I use this for auto loans?
Yes. It works for simple fixed-rate personal or auto loan estimates.
Does extra payment reduce interest?
Usually yes. The calculator estimates the interest saved by paying more each month.
Does it include taxes or fees?
No. Add those separately if they are financed into the loan amount.
Does it use a server?
No. The payment estimate runs in your browser.
