ProjectionLab Review: The Ultimate DIY Financial Planning Tool

ProjectionLab is a powerful DIY financial planning tool that helps you simulate your entire money life, test “what‑if” scenarios, and see whether you’re truly on track for retirement or financial independence. Instead of wrestling with fragile spreadsheets or paying thousands to an advisor, you can build detailed long‑term projections in your browser using clear charts, timelines, and Monte Carlo simulations.

At its core, ProjectionLab lets you create a life‑timeline, add income streams, investments, debts, big purchases, and milestones, then forecast your net worth and cash flow decades into the future. It’s especially popular in the FIRE community because it can handle non‑traditional paths like early retirement, mini‑retirements, and career breaks with much more nuance than a basic retirement calculator. You can clone your base plan and compare scenarios side‑by‑side, such as retiring at 55 vs 65, moving to a lower‑cost area, or switching to part‑time work to see how each choice affects your long‑term outlook.

One of the most impressive features is its visual output, including Sankey‑style cash‑flow diagrams, net‑worth charts, and success‑probability graphs from Monte Carlo simulations. These help turn complex numbers into an intuitive picture you can review on your own or share with a partner. ProjectionLab also goes deeper than most consumer tools on taxes, giving you realistic estimates by account type and supporting strategies like Roth conversions and careful withdrawal planning.

Privacy is another major selling point: ProjectionLab is built as a planning simulator, not an account aggregator, so you don’t have to link your bank or brokerage accounts if you prefer to enter data manually. That makes it attractive for security‑conscious users who want professional‑level planning without handing over all their sensitive information to yet another app. The platform is also actively developed, with new features and refinements being added regularly based on user feedback, which helps it stay ahead of many traditional calculators and static spreadsheet templates.

In terms of cost, ProjectionLab offers a free basic tier for experimenting with the software and paid plans that unlock plan saving, advanced scenarios, and advisor features. The commonly recommended sweet spot for individual users is the premium subscription, which is far cheaper than paying a 1% assets‑under‑management fee on a sizable portfolio, especially for serious DIY investors. For financial coaches and advisors, there’s also a Pro tier with client seats and a dedicated dashboard, turning ProjectionLab into a lightweight professional planning suite.

ProjectionLab isn’t perfect: there’s a learning curve, initial setup takes time, and it doesn’t execute trades or sync every transaction automatically. Still, if you’re a hands‑on planner who loves the FIRE mindset, wants to stress‑test your future, and prefers full control over your assumptions, ProjectionLab is one of the best retirement and financial independence planning tools available today.
