The Ultimate Directory of FIRE Calculators

(no. 022)

Straight to the Point

A directory of useful FI/RE calculators and spreadsheets.

Why?

In the process of making the original FI Checkpoint Test and the subsequent version 2.0 (FI Score Test), I did a bit of research to see what was already out there. Rather than all my notes go to waste, I thought I would create a directory for everyone.

There are so many spreadsheets and calculators out there. Many of them do the same things but they can present the data differently, ask for different variables or have different user interfaces.

You might like the way one calculator present things over another despite them both doing the same thing.

Some might even be better than others.

It makes sense to have a directory for them all.

The directory does not have a rating system. It is not my place to do so. Plus, it’s all very subjective. Most of them have been completed by people in their spare time and donated to the community for free.

So instead of ranking them, I have just listed them all in the order I found them, along with brief descriptions and a screenshot. It is very US heavy at the moment, with some representation from the UK and Canada. Nothing from other European countries or Asia at present, but that is down to how Google ranks the searches for me.

How?

The directory should be pretty simple to use.

There is a search box and if you enter an asterisk “*”, it will show you my current favourite ones. These will likely change over time as my needs change.

Click on the name of the spreadsheet or calculator to take you to the author’s post with instructions on how to use it.

You can click on the screenshots to enlarge.

I have tried to be inclusive as possible and included what I could find out there. Some of the very, very basic calculators I have not included. If I have, I have not added others which does and presents things in exactly the same way.

Although the directory started off as solely for FIRE calculators, I have also included spreadsheets which I think might be useful for those pursuing FI.

Contact me if there is an entry you’d like me to add or if you create one yourself!

Also, let me know if the directory could be changed to make it more useful. If we end up with hundreds, then another column to help filter might help.

Finally, anything listed in the directory is not a personal endorsement from me. I have not tested them thoroughly. I make no guarantees as to the accuracy of these calculators or spreadsheets.

Embrace your inner nerd and have fun playing around with them!

Note: I’ve started to include a direct download link to some of the spreadsheets in the event the original blogger calls it a day and the their link stops working. If they were originally Google sheets, then I have converted them to Excel. As a result, some functionality may be lost. Always use the link in the name column first.
