I just realised my "high savings rate" was mostly income growth, my habits barely changed.
I've been tracking my finances properly for years, ever since I first discovered FIRE. Every month I log my income, expenses, and savings rate. Felt quite smug about it too, my savings rate climbed from around 25% in year one to about 52% last year. I assumed that meant I'd got progressively better with money.
Then last week I dug into the actual numbers properly instead of just glancing at the headline rate. Turns out, of that 27 percentage point increase, roughly 20 points came purely from salary growth and a couple of promotions. My actual spending habits had barely shifted. I was just earning more and saving the difference almost by accident.
When I broke it down further, it got a bit uncomfortable. My essential spending (rent, bills, food, transport) had stayed roughly flat as a percentage. But my discretionary spending had actually gone up in absolute terms, I'd just been masked by the income increases. Things like more takeaways, upgrading subscriptions, and generally spending a bit more freely because "I can afford it now."
The scary part: if I'd maintained my year-one spending habits and put the income increases entirely into investments, I'd have roughly an extra £40k in my portfolio right now. That's not a small number. That's potentially 1–2 years off my FIRE date.
I'm now going back to basics. Actually budgeting properly instead of relying on the savings rate to flatter me. Automating more of the surplus rather than spending it by default. Looking at where I can be more intentional, not depriving myself, but making sure each spending decision is deliberate rather than habitual drift.
Curious if anyone else has had this realisation. I suspect it's quite common, earning more masks a lot of spending creep. For those of you who've successfully kept spending flat (or even reduced it) while your income grew, what actually worked? I feel like I need a system rather than just good intentions.
