FinancialAha Free Calculators - Free financial calculators. No signup. No tracking.

by•
Most financial calculators either hide results behind email walls or track everything you enter. We built something different. 40+ calculators for savings, debt, retirement, mortgages, taxes and more - completely FREE and private. Your numbers never leave your browser. No account needed. No data stored. No ads. From compound interest to FIRE planning, debt payoff to Social Security optimization get accurate answers without the privacy trade-off. Bookmark it once, use it whenever you need it.

Hey Product Hunt! 👋 I'm Stefan, co-founder of FinancialAha. Quick backstory: I reached financial independence at 27 and wanted to help others do the same. But when I searched for a simple calculator (e.g. compound interest, debt payoff, retirement projections) many times I'd hit an email wall or get bombarded with ads. So I built the tools I wished existed for free. 40+ calculators covering: - Savings & emergency funds - Debt payoff (snowball vs avalanche) - Compound interest & investments - Retirement, FIRE & Coast FIRE - Mortgages, rent vs buy, refinancing - Auto loans & affordability - Income tax & capital gains Everything runs client-side. Your financial data never hits our servers. No signup, no tracking, no "enter your email to see results" nonsense. This is part of FinancialAha - we also sell Google Sheets templates for budgeting and net worth tracking. Same philosophy: one-time purchase, no subscriptions, no bank account linking. Would love your feedback - which calculators do you find most useful? Any gaps we should fill? Thanks for checking it out! 🙏
