When trying to figure out whether or not I can FIRE I’ve needed to understand just how much I spend (along with a few other numbers). To calculate this properly I started a few years ago to track every penny that I spent. With this data I can then also make pre to post-FIRE estimates more accurately. For example, in my case I know I can net off work related costs and rent but I know I have to add on home maintenance costs. This is what my spending has looked like over the past few years:
In 2015 I spent £24,413 and in 2016 I spent £27,001. If I did nothing 2017 could be around £26,000 but FIRE is coming (could come?) this year so my spending profile will (could?) transition from pre to post-FIRE so that’s not bankable.
The other advantage of tracking spending like this is that you start to understand what your personal inflation is actually looking like which allows you to take action if it’s starting to get out of hand. It’s no good going into FIRE with a planned spending of £20,000 per annum, which you then plan to increase with published inflation, only to find you’re actually spending £25,000, which is then increasing at a rate greater than inflation. That’s a road to potentially running out of wealth before you run out of life.
