it is really hard as things are constantly creeping up in price. I’m having a similar issue and these sound like really frugal measures. But…..
This is a list of things you don’t do and it isn’t helpful on its own. Have you tracked every penny of your spending for a few months? Do you know exactly where you do spend? There could be categories in here that we don’t know about.
I have been using YNAB for a few years and it’s been really helpful for this. You have to pay for it, although they have some free trials. It’s a little bit of a learning curve but it’s great for tracking every single penny and your spending habits in general. Literally everything I spend I have to assign to a category. I don’t allow my self any purchases that aren’t itemised.
you can also spilt a transaction too so if you picked up uniform at the supermarket, it doesn’t just get lumped in with food. likewise any annoying Amazon purchases where you might have bought printer ink and a present for a kids party. You can put these into the correct category. I thought I was spending a ridiculous amount on food until I realised how much of my supermarket bill was extras, knowing hasn’t changed this spending but now I can really watch these and cut back in the right places!
You could keep a spreadsheet but I just find YNAB easier because I can tally my running total with my bank balance. I input the daily spending manually and I know exactly how much I have left for the month at any given moment. Usually very little!
At the end of every month I will pull the categories into a separate spreadsheet for analysis. So I can see what costs are increasing over time.
ynab isn’t great for forecasting, but it’s not really meant for this so you will need to pull the category totals out and do that separately. But it is fantastic for day to day spending!
The worst category I found was water. We paid £40/50 a month 6 years ago. We actually use less water now than we did then as we’ve tried hard to cut back, but despite this our bill is now £160 (south east water I’m looking at you!) there is nothing I can do about this as we are tied to our supplier. This category I have to accept but other utility’s I have some leeway with and when you track absolutely everything you may find other areas that you can cut back on things you realise you regularly spend and would be better bought in bulk to save money.
Solidarity though - it is really tough! Maybe you have tracked like this already? But if not it’s worth a shot…
