About FinCalc

FinCalc is a free collection of 40 financial calculators covering personal finance, investing, business, and real estate โ€” built to give clear, accurate answers without signups, paywalls, or spreadsheets.

What you'll find here

Loan and mortgage payments, retirement and FIRE planning, SIP and CAGR growth projections, stock valuation tools like DCF and P/E-based models, startup and small-business calculators (burn rate, equity dilution, break-even), tax estimators, debt payoff strategies, and more โ€” all organized by category on the calculators page.

How the calculators work

Every calculator runs entirely in your browser using standard financial formulas (compound growth, amortization schedules, Newton's-method root-finding for IRR/XIRR, and so on). Nothing you type is sent to a server, logged, or stored โ€” see our Privacy Policy for details.

Not financial advice

These tools are built for clarity and speed, not as a substitute for professional advice. Results are estimates based on the numbers you enter and standard formulas โ€” they don't account for your full financial picture, tax situation, or changing market conditions. For decisions that matter, please consult a qualified financial advisor, accountant, or tax professional.

Accuracy

We aim for every calculator to be formula-correct and well-tested, but financial rules (tax brackets, contribution limits, etc.) change over time and vary by country. Always double-check figures that affect real decisions against current official sources.
