Financial calculators for investors

Free interactive calculators for retirement, debt payoff, home affordability, college savings, equity compensation, Roth vs Traditional IRAs, and more. Use them for education and planning—then sign in at app.quantridge.net for portfolio-linked models, tax tracking, and saved scenarios.

Each calculator runs in your browser with clear inputs and plain-language outputs. They are a starting point—not a substitute for tax or investment advice from a licensed professional.

Inside QuantRidge, the same assumptions can connect to linked accounts, lot-level tax context, and long-horizon models you can revisit over time.

Results are illustrative only and not financial, tax, or investment advice. Rates, limits, and rules change—verify with primary sources or a professional before acting.
