Free 401k Calculator Spreadsheet Template for Google Sheets & Excel
A salary, the share of it you contribute, your employer's match rate and the ceiling it stops at, the years you have left and a return you supply rather than one assumed for you. The Free 401k Calculator spreadsheet template gives back the annual amounts, your contribution and theirs shown apart, and a projected balance at the end. One working sheet, one figure that matters, and a How to Use tab beside it. Google Sheets or Excel. No macros, no VBA, no sign-up.
The FinancialAha Free 401k 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 401k Calculator Excel template and a Free 401k Calculator Google Sheets template from the same download. This Free 401k Calculator spreadsheet template takes a salary, the share you contribute, the employer's match rate and the ceiling it stops at, a number of years and an assumed return, and projects what the account reaches. No macros, no VBA, no sign-up.
Inside the workbook
What's inside the FinancialAha Free 401k Calculator spreadsheet template
The FinancialAha Free 401k Calculator Spreadsheet Template runs on a single 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 401k Calculator spreadsheet holds.
01of 01
401(k)
Six figures in and four back: what you put in each year, what the employer adds, the two together, and what the account reaches after the years you set at the return you assume.
Seeing your contribution and the employer's separately is the part worth having. They are different kinds of money - one is deferred pay you chose to set aside, the other is compensation contingent on your setting it aside - and a single combined figure hides which is which.
The match is modelled the way most arrangements are actually written: the employer adds a proportion of what you contribute, up to a maximum share of your salary. Both halves are yours to set, so a match that stops at a ceiling stops here too.
What this build does not do: there is no current balance, so it projects from nothing; the salary is held flat for the whole period; and the answer is a single figure at the end rather than a year-by-year path.

Included guide
How to Use
A step-by-step guide on its own tab, covering 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

Free 401k Calculator Google Sheets template setup
A shared copy of the Free 401k Calculator Google Sheets template is useful in a conversation with a partner or an adviser, since the assumed return is the contested input and it sits in a visible cell rather than inside a formula. Sheets version history covers a figure typed over.
Sharing the Free 401k Calculator Google Sheet
The Free 401k Calculator Google Sheet is built for a sitting rather than a routine: put the figures in, read the projection, then change the contribution share or the return and read it again. Seeing what a percentage point of contribution does over decades takes a few seconds.

Opening the Free 401k Calculator spreadsheet Excel file
Nothing in the Free 401k Calculator Excel template is version-specific, so this Free 401k Calculator spreadsheet Excel workbook behaves identically in Excel on Windows, Excel on Mac, and older builds.
The FinancialAha Free 401k Calculator Spreadsheet Template models the employer match the way most arrangements are written - a proportion of what you contribute, up to a ceiling you set - and returns a single projected figure from a flat salary over a number of years. The Essentials 401k Calculator Spreadsheet Template for Google Sheets and Excel adds what the one-sheet build cannot hold: the balance you already have, your age and retirement age, a salary growth rate, and a year-by-year projection that separates your contributions, the employer's, and the growth on both. Two charts sit alongside.
Notes on working in the Free 401k Calculator spreadsheet template
Your contribution and the employer's are shown apart, because they are different kinds of money.
The two match cells work together: a proportion of what you put in, up to a ceiling. Setting the ceiling to your own plan's is what keeps the match figure honest.
There is no current balance in this build, so it projects from nothing rather than from what you already hold.
The answer is a single figure at the end. The Essentials build lays out every year between now and retirement instead.
The salary is held flat for the whole period, so a long projection ignores every raise along the way.
The return is an assumption, not a forecast. Testing two or three is more useful than settling on one.
How the 401k Calculator template works
The Free 401k Calculator Spreadsheet Template takes a salary, the share of it you contribute, an employer match, a number of years and an assumed return, then reports what you put in each year, what the employer adds, the two together, and what the account reaches. Seeing your contribution and the employer's apart is the point - they are different kinds of money. The match is modelled the way most arrangements are written, as a proportion of what you contribute up to a ceiling you set. The limits sit elsewhere: it projects from nothing rather than from a balance you already hold, the salary is held flat for the whole period, and the answer is a single figure at the end rather than a year-by-year path.
When this template helps
01
You want to see what your current contribution rate builds over time.
02
You are deciding whether to raise the share you put in.
03
You want the employer contribution shown separately from your own.
04
You want a projection you control rather than a calculator on a provider website.
Tips to get the most out of it
The post-adjustment figures are only as good as the return you assumed, and it is the input worth testing twice.
Your contribution and the employer's are worth reading apart, because they are different kinds of money.
A match that stops at a ceiling stops here too, so the ceiling cell is worth setting to your own plan's.
Common mistakes to avoid
Leaving the ceiling on the sample figure. The match stops where that cell says, so a plan with a different cap comes out wrong.
Entering a rate as a whole number rather than a percentage. Everything downstream moves by a factor of a hundred.
Reading the projection as a forecast. It is entirely a product of the return you assumed.
Ignoring salary growth over a long horizon. Contributions rise with pay, and this build holds pay still.

Frequently Asked Questions
What is the difference between the free and Essentials Free 401k 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. This template has no Ultimate build. What each tier holds differs by template - the comparison table on every template page lists it exactly.
Which Free 401k 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 401k 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 401k 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 401k Calculator Google Sheets template, and the currency dropdown still relabels the money fields.
Is the FinancialAha Free 401k Calculator Spreadsheet Template an Excel template?
Yes. The download is a plain .xlsx, so the Free 401k 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 401k Calculator spreadsheet Excel file open in older versions of Excel?
Yes. The Free 401k Calculator spreadsheet Excel workbook ships as a plain .xlsx, so it opens identically in current Excel and in builds that predate dynamic arrays.
How does the FinancialAha Free 401k Calculator Spreadsheet Template handle the employer match?
As a proportion of what you contribute, up to a ceiling set as a share of your salary - which is how most arrangements are written. Both figures are yours to enter, so a match that stops at a ceiling stops here too. What this build does not do is start from a balance you already hold or grow the salary as the years pass.
Can I start from a balance I already have?
Not in this build - it projects from nothing. A current balance, along with your age and retirement age, is on the Essentials build.
Does the salary grow over the projection?
No. It is held flat for the whole period, so a long projection ignores every raise along the way. A salary growth rate is on the Essentials build.
Is the file 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 401k Calculator spreadsheet template in Google Sheets?
