Financial independence means your investments can pay for your spending without relying on a paycheck. Some people call that FIRE, short for "financial independence, retire early", but the core question is simpler: if you retire at a chosen age with a chosen lifestyle, does the money last?
You enter your age, current savings, ongoing contributions, planned retirement age, monthly spending, investment returns, Social Security, and one-time life events. The planner shows whether that exact scenario lasts through your planning age, then explains the earliest retirement age projected to work under the same assumptions.
Use simple return assumptions for a quick answer, or switch to detailed portfolio returns when you want to model stocks, bonds, and cash separately. Scenario simulation can stress-test the plan across market paths when you want a less deterministic view.

Frequently asked questions
How is the Financial Independence Planner different from the Retirement Planner?
The Financial Independence Planner uses the same mature cash-flow engine, but the wording and headline focus on the early-retirement question: "If I retire at this age with this monthly spending, does the money last?"
What withdrawal rate should I use?
The default view uses a fixed monthly spending amount in today's dollars, then grows it with inflation each year. You can switch to a percent-of-portfolio withdrawal rule if you want spending to move with the portfolio instead.
What does FIRE mean?
FIRE stands for "financial independence, retire early." You do not need to know the acronym to use the planner: it is simply testing when your investments can support retirement spending without a paycheck.
Do I need to create an account?
No. The planner works without signing in. If you want to save plans across devices, sign-in is free with Google or email.
