I think my take home (largely thanks to tax changes - my gross is actually less) is about £80 higher per month than it was twelve years ago. Part of that is retraining, but it’s also just austerity devaluing what I do. Great stuff.
I don’t really spend a lot on myself, mainly cos I spend a lot travelling to Edinburgh. In terms of economising tho. I guess my main tips would be just to find a way to track not just how much you spend but also what you spend it on?
Like, I obsessively track everything I spend through a spreadsheet. Started with my monthly take home pay, minus rent, multipled by twelve and divided by 52 to get a weekly figure. Put that into a week-by-week spreadsheet, and log every day what I spend. Really puts the amount you waste on inconsequential stuff (like lunches or takeaway coffee) into a bit of perspective. It’s so easy to do that, especially now that contactless is the norm. Gives me more cash to spend on actual useful stuff.
