Title: FI calculations with side hustle expenses/income
Post by: treesner on December 08, 2019, 12:21:56 AM

Hey guys how would I do FI calculations with my side hustle expenses and income? my side hustles are my hobby and I will continue to do them in FI but not sure for how long. I don't have a huge profit from it but I do have a lot of expenses, these expenses really bloat my yearly spending. How would you factor these into FI calculations?

I was looking to fill out this spread sheet out from the mad fientist https://www.madfientist.com/financial-independence-spreadsheet/

Does your side hustle income completely cover related expenses? You mentioned not having much profit from your side hustle which makes me think you’re breaking even currently, in which case I’d just leave the side hustle completely out of the calculations since its income covers its expenses. So for example, if your side hustle earns you $1000/month but the expenses are $1000/month (for a PROFIT of $0/month), and your living expenses is $2000/month, then your FIRE number is $600K ($24K x 25).

However, if you actually mean you don’t make much income from your side hustle, and its income is not sufficient to cover its related expenses, then I’d just figure out how much you’re spending on your side hustle expenses and add that to your annual expenses when calculating your FIRE number. So for example, if you normally spend $2000/month on your living expenses plus another $1000/month on your side hustle, for a total of $36K per year, then your FIRE number would be $900K (36K x 25).
