RetireGolden review
A free, open-source browser tool for detailed retirement and tax scenario modeling.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
RetireGolden is a browser-based retirement planning calculator for people evaluating savings, income, spending, taxes, withdrawals, and retirement timing. It builds year-by-year household projections and is aimed at users who want to explore how different choices may affect retirement outcomes. Its free, open-source model suits people looking for a detailed planning tool without creating an account, while it is not a substitute for professional advice.
The modeling spans Social Security claiming ages, including spousal and survivor benefits, as well as federal and state tax estimates. Those estimates cover required minimum distributions, Roth conversions, ACA premiums, and IRMAA. Monte Carlo analysis adds success rates and percentile bands to help frame uncertainty, and side-by-side scenario comparison makes it possible to examine alternative assumptions. Withdrawal and Roth-conversion optimization add further depth for users focused on how assets are drawn down. Tax estimates are described as planning-precision rather than tax-return software, so users needing a return prepared or tax advice should choose a different service or consult a professional.
Plans are calculated and stored locally in the browser, without accounts or server-side plan storage. JSON plan export and import provides a way to move a plan, but account syncing and integrations are not part of the offering. This browser-centered approach will appeal to people who prefer local storage and are comfortable managing scenarios themselves; users seeking connected financial accounts or an integrated workflow should look elsewhere. RetireGolden is positioned as an educational modeling tool, not personalized financial, tax, legal, or investment advice.
