The site also has Barista FIRE, Coast FIRE number, FIRE number, Lean FIRE and Fat FIRE calculators, plus plain-English guides.

Focused on Coast FIRE
The tool is built around the Coast FIRE concept, which is reaching a savings level where compound growth alone can fund retirement while you only cover current expenses. This makes it more targeted than general retirement calculators, which often don't highlight a 'coast number'.
Clear coast number calculation
Users typically enter inputs such as current age, target retirement age, savings, expected return, and desired retirement spending. The tool then shows how much is needed now to coast, which turns an abstract goal into a concrete milestone.
Scenario exploration
Adjusting variables like retirement age, return rate, inflation, or spending lets users see how each assumption changes their timeline. This supports decisions about career changes, part-time work, or sabbaticals.
Accessible and beginner-friendly
A single-purpose web calculator is quick to learn and doesn't require financial expertise or spreadsheet skills. It is useful for people new to the FIRE community who want a fast estimate.
Motivational and planning value
Seeing a specific coast target and how close you are can encourage saving and help set intermediate goals. It also helps in judging when it is safe to ease off aggressive saving.
Most Coast FIRE calculators give you one number. Coast FIRE Planner tells you the month you can stop saving, your odds of success across 1,000 simulated markets, and how saving more, retiring later, lower returns or higher fees would move that date. It’s free, needs no sign-up, and keeps your numbers in your browser.
It goes beyond a single estimate. It factors in investment fees and inflation, shows how likely your plan is to work rather than assuming average returns every year, and lets you share any result with a link. It works in USD, CAD, GBP, EUR and AUD, with guides for Canada, the UK and Australia, and every formula and source is published on the methodology page.
People working toward financial independence, mostly in their 20s to 40s, who want to know when they can stop saving for retirement and switch to lower-stress work, part-time work or simply spending more today. It suits beginners learning about FIRE as well as experienced planners who want to stress-test their numbers.
It started with a simple question: “When can I stop saving for retirement?” Existing calculators gave a single number based on average returns, with no sense of how likely it was or what would change it. Coast FIRE Planner was built to answer the question properly: the exact month, the odds, and the levers that move it, explained in plain language.
