Loan Calculator
This loan calculator helps you estimate the monthly payment and lifetime borrowing cost for a standard amortizing loan.
The page is useful for personal loans, renovation loans, and other fixed borrowing scenarios where users want a fast monthly payment estimate plus a realistic view of total interest. The extra-payment comparison also turns it into a planning tool instead of a one-number answer.
Enter the loan amount, interest rate, and term to estimate monthly payment, total interest, and total paid. You can also add an extra monthly payment to see how faster payoff changes the outcome.
