Free Loan Calculator Online
This free loan calculator online helps you estimate a monthly loan payment, total interest, total repayment, and a yearly amortization schedule. Enter the amount you plan to borrow, the annual interest rate, loan term, and starting month to see an estimate based on a standard fixed-payment amortization formula.
Calculate Monthly Loan Payments
Use this monthly payment calculator to see how loan amount, interest rate, and repayment term affect your payment. The calculator uses the standard monthly-rate formula for an amortizing installment loan. A longer repayment term can reduce the monthly payment while increasing the total interest paid, all else being equal.
Loan Payment Formula
For a fixed-rate amortizing loan with a positive interest rate, the monthly payment is calculated using the principal, monthly interest rate, and total number of monthly payments. When the interest rate is 0%, the payment is simply the loan amount divided by the number of payments.
Monthly payment = P × r × (1 + r)n ÷ ((1 + r)n − 1), where P is the loan amount, r is the monthly interest rate, and n is the number of monthly payments.
Loan Calculator for Personal, Auto and Other Loans
You can use this calculator to estimate payments for many fixed-rate installment loans, such as a personal loan calculator use case, an auto loan calculator use case, or general borrowing scenarios. It is an estimate rather than a loan offer, and it does not account for every lender-specific fee, tax, insurance charge, or variable-rate condition.
Loan Calculator for US and UK Users
This calculator displays amounts using the dollar symbol and is suitable for users searching for a loan calculator USA or monthly payment calculator. The underlying amortization method can also help UK visitors researching loan repayments, although UK lenders may quote rates, fees, and repayment terms differently. If you are comparing loans in the UK, check the lender's quoted APR, fees, and repayment schedule rather than relying on a calculator estimate alone.
Understanding Total Interest and Amortization
Total interest is the estimated amount paid above the original principal over the full repayment period. The yearly amortization schedule shows how each year's payments are divided between principal and interest and how the remaining balance decreases over time.
Example Loan Calculation
For example, a $100,000 loan at 6.5% annual interest over 30 years produces a monthly payment of about $632.07 using the standard amortization formula. The exact result shown by the calculator can vary with the number of payments, rounding, fees, and the lender's actual terms.
What Can Change Your Monthly Loan Payment?
- Loan amount: Borrowing more generally increases the monthly payment.
- Interest rate: A higher rate generally increases both the monthly payment and total interest.
- Loan term: A longer term can reduce the monthly payment but may increase total interest.
- Fees and charges: Lender fees or other costs can change the actual cost of borrowing.
- Repayment structure: Variable-rate, interest-only, balloon, or irregular-payment loans may not match this fixed-payment estimate.
