Loan Calculator

This calculator uses your loan amount, annual interest rate, repayment term, start date, and optional extra monthly payment to estimate the cost of a fixed-rate installment loan.

Each regular payment is divided between principal and interest. Principal reduces the amount you owe, while interest represents the lender's charge for providing the loan.

When you enter an extra monthly payment, the calculator applies the additional amount toward the remaining balance. This can shorten the repayment period and reduce the total interest paid.

A standard installment loan payment is based on the principal, the monthly interest rate, and the total number of monthly payments.

In the formula, P is the original loan principal, r is the monthly interest rate, and n is the total number of monthly payments.

For a zero-interest loan, the monthly payment is normally calculated by dividing the principal by the number of payments.

A loan calculator is a financial tool that estimates your monthly payment, total interest, total repayment cost, and payoff timeline using the amount borrowed, interest rate, and repayment term.

It can be useful when comparing personal loans, auto loans, debt consolidation loans, and other fixed-rate installment loans. Instead of comparing offers using monthly payments alone, you can also examine the total cost of borrowing.

The amortization schedule provides additional detail by showing how the balance changes after each payment and how much of every payment goes toward principal and interest.

Your monthly loan payment depends mainly on the loan amount, interest rate, and repayment term. Borrowing more generally increases the required payment and the total amount of interest that may be paid.

The interest rate determines how much the lender charges for the loan. Even a small difference in rate can affect both the monthly payment and the long-term repayment cost.

A longer term usually reduces the monthly payment because repayment is spread over more months. However, it commonly increases total interest. A shorter term usually creates a higher payment but can reduce the total borrowing cost.

Additional monthly payments can reduce the balance more quickly, although borrowers should first check whether their lender applies extra payments to principal or charges prepayment penalties.

Shorter repayment terms generally produce higher monthly payments but lower total interest. Longer terms may reduce the amount due each month, but they often increase the total cost because interest is charged for a longer period.

Based on the values currently entered, a loan amount of $20,000.00 at an annual interest rate of 7.00% over 5 years produces an estimated monthly payment of $396.02.

The estimated total interest is $3,761.44, and the estimated total repayment cost is $23,761.44.

Adding an optional extra payment above can show how faster principal reduction may affect the payoff date and total interest.

Choosing a shorter repayment term can reduce total interest when the resulting monthly payment remains affordable. With fewer months of borrowing, interest has less time to accumulate.

Making extra payments toward principal can also reduce the outstanding balance and shorten the payoff period. Before doing this, check how your lender applies additional payments.

A lower interest rate may substantially reduce the cost of a loan. Borrowers may compare multiple lenders, improve their credit profile, reduce the amount borrowed, or consider refinancing when appropriate.

Fees also matter. An offer with a lower advertised rate may not always be cheaper when origination charges, service fees, insurance, or penalties are included.

This free calculator is designed to estimate fixed-rate installment loans with regular monthly payments. It can be used to explore personal loans, auto loans, debt consolidation loans, and similar borrowing arrangements.

Results are estimates based on the information entered. Actual lender calculations may also include origination fees, service charges, insurance, taxes, variable rates, payment timing rules, rounding methods, or prepayment penalties.

Use the results for planning and comparison, then verify the final figures against the lender's official disclosure and loan agreement before accepting an offer.
