Free Financial Calculators

Free calculators for the money decisions that actually come up — with the formula, schedule, or breakdown shown, not just a final number. Work out mortgage and loan payments with full month-by-month amortization schedules, project compound interest with a year-by-year growth chart, and check ROI or the units you need to break even. Everyday money math is here too: percentages, restaurant tips split any number of ways, stacked discounts, weekly hours from your time card, and a salary converter that translates pay between hourly, monthly, and annual. Every calculation runs instantly in your browser — nothing you enter is uploaded, stored, or logged.
