A Loan Calculator is a financial tool designed to help borrowers and lenders estimate loan repayment details. Users input key parameters such as loan amount, interest rate, loan term (in months or years), and repayment frequency. The calculator then generates a detailed amortization schedule showing monthly payments, total interest costs, and the loan payoff date. Some advanced versions can account for extra payments, variable interest rates, or different loan types (fixed-rate, adjustable-rate, personal loans, mortgages, etc.). This tool is essential for financial planning, comparing loan offers, and understanding long-term borrowing costs.
