Choose Beacon if you want a clear, manual view of investable assets and a projected FI date. Choose ProjectionLab if you want to model a detailed financial life, test scenarios, and explore simulations, taxes, and drawdown strategies.
Neither is a replacement for individualized financial, tax, or investment advice. They serve different planning styles, and some people may find value in using a focused tracker alongside a more advanced scenario tool.
At a glance
| Area | Beacon | ProjectionLab |
|---|---|---|
| Core job | Track investable assets and map a deterministic FI date. | Build and explore a detailed long-term financial plan. |
| Data entry | Manual balances and assumptions; no account connections. | Model accounts, income, spending, and life events in a planning workspace. |
| Projection method | Transparent deterministic projection. | Scenario planning, Monte Carlo simulation, and historical backtesting. |
| Advanced planning | Focused on the core FI inputs. | Includes richer tax, cash-flow, withdrawal, and estate-planning tools. |
| Best for | People who want a concise, repeatable FI dashboard. | People who enjoy detailed modeling and testing trade-offs. |
When Beacon is the better fit
Beacon is designed to make the few inputs that drive a financial independence plan visible: investable assets, annual spending, annual savings, expected return, and withdrawal rate. You enter values manually, so there is no bank or brokerage connection to maintain. The result is a deterministic FI date you can trace back to stated assumptions.
That approach works well when you want to review the plan periodically without constructing a full model of every future decision. It also makes it easier to distinguish total net worth from the assets that can plausibly fund spending.
When ProjectionLab is the better fit
ProjectionLab is built for people who want more nuance in a plan: multiple goals and milestones, detailed account types, cash-flow analysis, tax estimation, withdrawal strategies, and probabilistic or historical tests. Its official product materials describe both Monte Carlo simulations and historical backtesting, plus advanced tax and estate-planning features.
It is a strong choice if your question is not only “when could I reach FI?” but also “what happens if I change careers, move, alter spending, draw from different accounts, or use a different tax strategy?” That depth naturally comes with more setup and more decisions to maintain.
Deterministic date vs. probability range
These tools answer related but different questions. Beacon applies the inputs you choose to one transparent path. It is useful for understanding how a changed savings rate, spending target, expected return, or withdrawal rate changes the projected date.
ProjectionLab can help explore a range of possible outcomes through simulations and historical scenarios. That is useful for stress-testing, but a probability output is only as useful as its assumptions. A clear base case and a stress test can complement each other.
Which should you choose?
- Choose Beacon if you value a focused manual workflow, clear assumptions, and an always-visible FI date.
- Choose ProjectionLab if you want detailed scenario planning, historical or Monte Carlo analysis, and richer tax and drawdown modeling.
- Consider both approaches if you want a simple ongoing dashboard and occasional deep scenario work.
