Free Online Payment Calculator – Calculate Monthly Loan Payments Instantly
What Is a Payment Calculator?
A payment calculator helps you quickly estimate the monthly amount you’ll need to repay for a fixed‑rate loan. Whether you’re planning a mortgage, car loan, or personal installment, this tool uses the standard loan payment formula to give you a clear picture of your financial commitment.
How to Use This Calculator
Loan Amount: Enter the total amount you plan to borrow (e.g., 20000).
Annual Interest Rate: Provide the yearly interest rate in percentage (e.g., 5.5 for 5.5%).
Loan Term: Specify the loan duration in years (e.g., 5 years).
Click Calculate Payment (or the inputs auto‑update) to see your monthly payment, total amount to be paid, and total interest.
Understanding the Results
Monthly Payment: The fixed amount you’ll pay each month.
Total Payment: The sum of all monthly payments over the full term.
Total Interest: The extra money you pay beyond the borrowed amount.
For example, a $20,000 loan at 5.5% APR over 5 years results in a monthly payment of about $382. Total interest paid would be around $2,917.
Loan Payment Formula
This calculator uses the following standard amortization formula:
M = P × [ r(1 + r)n ] / [ (1 + r)n – 1 ]
Where:
P = Loan principal (amount borrowed)
r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
n = Total number of monthly payments (loan term in years × 12)
Use this calculator to compare different loan offers, understand the impact of interest rates, and plan your budget with confidence.
