You enter a loan amount, term length (in years or months), and annual interest rate. The tool applies the standard fully-amortizing PMT formula with monthly compounding to compute the fixed monthly payment. It then multiplies by the number of months for total paid and subtracts the principal for total interest. The payoff date is projected from today.
The interest rate is the cost of borrowing the principal. The APR (Annual Percentage Rate) includes the interest rate plus fees like origination charges, rolled into a single annualized figure. APR gives a more complete picture of total borrowing cost, but this calculator uses the interest rate alone.
A shorter term means higher monthly payments but significantly less total interest. A longer term lowers your monthly payment but increases the total cost. The right choice depends on your monthly budget and how much you want to minimize interest expense.
No. Origination fees, application fees, prepayment penalties, and credit insurance are not included. Your actual cost of borrowing may be higher. Ask your lender for the APR and total cost disclosure before signing.
Most personal and auto loans allow early payoff without penalty, but check your loan agreement. Paying extra each month reduces the principal faster and saves interest. Use our Loan Payoff Calculator to see the impact of extra payments.
