Free FIRE Calculator Spreadsheet Template for Google Sheets & Excel
Five assumptions in, three figures out. Take-home income, savings rate, what you already hold, what a year will cost once you stop, and a real expected return you set yourself so the assumption is never hidden. The Free FIRE Calculator spreadsheet template puts the target portfolio at twenty-five times your retirement spending, derives annual savings from your income and rate, and returns the years to reach it. One working sheet plus How to Use, in Google Sheets or Excel. No macros, no VBA, no sign-up.
The FinancialAha Free FIRE Calculator Spreadsheet Template is a one-sheet workbook for Google Sheets and Excel, with a How to Use guide on a second tab. It works as a Free FIRE Calculator Excel template and a Free FIRE Calculator Google Sheets template from the same download. This Free FIRE Calculator spreadsheet template takes what you earn, what share of it you save, what you already hold and what you expect to spend once you stop, and returns a target figure, the amount going in each year, and how long the gap takes to close. No macros, no VBA, no sign-up.
Inside the workbook
What's inside the FinancialAha Free FIRE Calculator spreadsheet template
The FinancialAha Free FIRE Calculator Spreadsheet Template runs on one working sheet, with the instructions on a tab of their own. It works in both Microsoft Excel and Google Sheets and here is what the Free FIRE Calculator spreadsheet holds.
01of 01
FIRE
The single working sheet, and the whole template. Five assumptions go in on the left - what you take home, the share of it you save, what you have invested already, what you expect a year to cost once you stop, and the return you are willing to assume - and three figures come back: the target portfolio at twenty-five times your retirement spending, what you are putting away each year, and how many years the gap takes to close at that rate. Every one of those inputs is yours, which is the point: the sheet does the arithmetic and takes no view on the assumptions.

Included guide
How to Use
A step-by-step guide on its own tab, covering setup, how to replace the sample values, and how to change the currency. Because it ships inside the file, the instructions travel with the template wherever it is opened.
Works in both Google Sheets and Excel

Upload the Free FIRE Calculator Spreadsheet Template to Drive, right-click it, and choose "Open with Google Sheets".

Free FIRE Calculator Google Sheets template setup
A shared copy of the Free FIRE Calculator Google Sheets template works when two people are planning one timeline, and Sheets version history covers an assumption typed over. One screen of inputs also makes the Free FIRE Calculator Spreadsheet Template quick to open on a phone when a number worth testing comes to mind.
Sharing the Free FIRE Calculator Google Sheet
The Free FIRE Calculator Google Sheet is built for a sitting rather than a routine: put your figures in, read the three results, then move the savings rate or the return and read them again. Because the Free FIRE Calculator spreadsheet has no table to scroll, testing a different assumption takes seconds.
Free FIRE Calculator Spreadsheet template for Excel
The Free FIRE Calculator spreadsheet Excel download is a plain .xlsx. Excel opens this Free FIRE Calculator Excel template directly, with no import step and no compatibility prompt, and every figure updates the moment an input changes.

Free FIRE Calculator Excel template setup
The same Free FIRE Calculator Excel template opens in Excel on Windows, Excel on Mac, and Excel for the web. It is also the identical file you would upload to Drive, so there is no separate Free FIRE Calculator spreadsheet download to choose between.
Free FIRE Calculator spreadsheet Excel notes

Opening the Free FIRE Calculator spreadsheet Excel file
Nothing in the Free FIRE Calculator Excel template is version-specific, so this Free FIRE Calculator spreadsheet Excel workbook behaves identically in Excel on Windows, Excel on Mac, and older builds.
The FinancialAha Free FIRE Calculator Spreadsheet Template covers one working sheet and returns three figures. The target is fixed at twenty-five times your retirement spending, which is the honest limit of the Free build: there is no settable withdrawal rate, no year-by-year table, no age, and no chart. The Essentials FIRE Calculator Spreadsheet Template for Google Sheets and Excel makes the withdrawal rate an input, works in your current age so the answer arrives as a date rather than a duration, and lays the whole path out year by year with a flag on the year the target is met, reported on a dashboard with two charts. The Ultimate FIRE Calculator Spreadsheet Template goes further again, comparing lean, regular and fat targets side by side, working out whether compounding alone would get you there without further saving, and modelling the drawdown afterwards.
Notes on working in the Free FIRE Calculator spreadsheet template
The target is twenty-five times the retirement spending you enter, and that multiple is fixed here - setting your own withdrawal rate is what the Essentials build adds.
The return field is a real return, meaning after inflation, rather than the headline figure a fund quotes.
A portfolio already at or above the target returns zero years rather than a negative.
Where the numbers cannot close the gap at all, the years figure says so rather than returning an error.
The dropdown beside the title relabels the money fields. It changes the label and nothing else.
How the FIRE Calculator template works
Takes what you earn, the share of it you save, what you already hold and what a year will cost once you stop, and returns a target portfolio, the amount going in each year, and how long the gap takes to close.
When this template helps
01
You have read about the 25x rule and want it applied to your own annual spending rather than to a worked example.
02
You want to see what moving the savings rate a few points does to the years figure.
03
What you would spend after stopping work is not what you spend now, and the target here is built on the retirement figure rather than on income.
04
You want the years-to-target number in a file you can reopen as the invested balance moves.
Tips to get the most out of it
Every assumption here is yours to supply, and the years figure moves a long way on small changes to the return or the savings rate.
Two or three returns say more than one, because the spread between them is closer to the real answer than any of them is.
Retirement spending drives the target directly, so it is the input worth the most thought.
Common mistakes to avoid
Entering a headline return where a real one is asked for, which shortens the timeline by years.
Using current spending as retirement spending without thinking about what actually changes.
Treating a single run as settled. The years-to-target figure moves a long way on small changes to the return or the savings rate.

Frequently Asked Questions
What is the difference between the free, Essentials, and Ultimate Free FIRE Calculator spreadsheet template?
Free is a single-sheet starter template with sample data and a How to Use guide. Essentials ($19) is the fuller build - more capacity, more detail, and more worked out for you rather than typed. Ultimate ($29) goes further again, usually six working sheets, giving each part of the template its own sheet and adding deeper reporting on top. What each tier holds differs by template - the comparison table on every template page lists it exactly.
Which Free FIRE Calculator spreadsheet template should I download?
Upgrade to Essentials if you want a dashboard with charts, more categories, larger capacity, and a more polished spreadsheet for ongoing use. The Free version is a good fit for one-off planning or trying out the layout.
Can I upgrade the Free FIRE Calculator spreadsheet template later?
Essentials is a one-time $19 purchase with no subscription. It typically adds a full dashboard, 30-50% more categories or rows than the Free version, and richer formulas. Most buyers upgrade after using the Free version for a few weeks and hitting its limits.
Is the FinancialAha Free FIRE Calculator Spreadsheet Template a Google Sheets template?
Yes. Upload the file to Drive and choose "Open with Google Sheets". Nothing needs rewriting in the Free FIRE Calculator Google Sheets template, and the currency dropdown still relabels the money fields.
Is the FinancialAha Free FIRE Calculator Spreadsheet Template an Excel template?
Yes. The download is a plain .xlsx, so the Free FIRE Calculator Excel template opens directly in Excel with no import step. There are no macros and no VBA, so it opens without a security warning.
Will the Free FIRE Calculator spreadsheet Excel file open in older versions of Excel?
Yes. The Free FIRE Calculator spreadsheet Excel workbook ships as a plain .xlsx, so it opens identically in current Excel and in builds that predate dynamic arrays.
Can I change the withdrawal rate in the FinancialAha Free FIRE Calculator Spreadsheet Template?
No. The Free build derives the target at a fixed twenty-five times your retirement spending. The Essentials build makes the withdrawal rate an input, so the target moves with the rate you choose, and adds a year-by-year projection.
Which inputs should I edit in the Free FIRE Calculator spreadsheet?
All five on the left: annual take-home income, savings rate, current invested, annual spending in retirement, and the real expected return. The three results on the right are derived and update as you type.
What does "real expected return" mean in the Free FIRE Calculator spreadsheet?
A return after inflation has been taken off, rather than the headline figure a fund quotes. It is an assumption you supply, and the years-to-target figure is sensitive to it.
Is the Free FIRE Calculator spreadsheet template safe to download?
Yes. No macros, no sign-up, no tracking. The file is a plain .xlsx that opens directly in Excel or Google Sheets.
How do I open the Free FIRE Calculator spreadsheet template in Google Sheets?
