About the Loan Calculator
high volume / high competitionThe Loan Calculator is a free online financial tool designed to calculate monthly payments, total interest, and total cost for any loan, with support for down payments, monthly fees, and income-based affordability analysis using the standard 28/36 debt-to-income rule. If you need a full breakdown of property taxes, insurance, and PMI, use our Mortgage Calculator instead.
This tool provides interactive sliders for loan amount, interest rate, and term (1-30 years), plus down payment and monthly fee inputs. It includes an income and affordability panel that computes your maximum housing payment and total DTI ratio. A side-by-side scenario comparison lets you test up to three alternative rate/term combinations to find the best total cost. The payment breakdown is visualized through an interactive SVG doughnut chart, and a full amortization schedule is available in both annual and monthly views with CSV export.
