ProjectionLab
Scenario-rich retirement planning with taxes, cash flow, and FIRE goals.
ProjectionLab is a web-based financial planning tool for modeling retirement, financial independence, major life events, taxes, investments, and estate outcomes. It lets users build long-range scenarios, run Monte Carlo simulations and historical backtests, compare drawdown and contribution strategies, and track actual progress against projections.
Why it stands out
- Goes beyond simple retirement calculators by modeling life events such as part-time work, travel breaks, recurring purchases, rental income, and black-swan scenarios.
- Built-in optimizer can coordinate Roth conversions, capital-gain harvesting, and withdrawal order around tax brackets, IRMAA cliffs, and ACA limits.
- Manual-entry approach avoids requiring direct links to bank or brokerage accounts.
- Includes both personal planning workflows and a separate advisor-focused version.
- Supports a growing set of non-U.S. planning assumptions, rather than being limited to a single-country model.
Good to know
- The free option is limited to basic retirement projections; advanced tax, cash-flow, optimization, estate, and withdrawal features require Premium.
- Because it does not link to financial accounts, users need to enter and maintain their own data.
- International planning is limited to the supported presets and account types, so coverage may not fit every country or situation.
- Projection results depend heavily on user assumptions and model choices, and should not be treated as guaranteed outcomes.

Compare whether retiring early, going part-time, or taking a travel break still leaves enough margin. Test Roth conversions, withdrawal orders, and capital-gain harvesting before making tax-sensitive decisions. Estimate cash flow, taxes, and net worth year by year under different market assumptions. Model major purchases, rental income, student-loan payoff, or estate outcomes alongside retirement goals.
