If you are having to decide between fun and big birthdays the you aren’t budgeting at all. That’s just decide month spending l. Budgeting is done in advance. It’s not boring at all. I have £500 now I can spend on whatever I want in my fun fund! You presumably have know about a birthday for some time and most people spend something each month on entertainment.
I use the three account system, Salary and DD, spending and savings. The DD account has just enough to cover the DDS, I estimate my monthly and annual spending and transfer to the spending account and the rest is saved into a long term saving pot.
The spending account is monthly and annual spends and an emergency fund. I put the emergency fund and annual spends into “pots” or spaces. Every 4 months I plan what I have coming and work out how much I need and ensure the is enough in the annual pot.
In the next 6 months I have a theme park trip, holiday, a big birthday a normal family birthday and two weekends breaks plus Christmas. These are all annual.
I have monthly pots for food, clothes, hair, beauty and make up, pets, and travel and gifts. But this isn’t necessary - I just wanted to stop overspending!
I used to get caught out with unexpected gifts, car tyres, glasses and contact lenses, dentist bills and prescription or illnesses. I spent £18 on cold and flu stuff the weekend which sounds insane but night nurse is £10 a bottle.
or I need three prescriptions. So I have a pot called health
I might switch between hair and clothes but tend to be quite rigorous in keeping to the pots.
Don’tUnderestimate spending because you will then dip into emergency fund or worse savings or even worse credit card.
When I started out I did a monthly spreadsheet and accounted for every penny, but now I just do it every 6 months and treat the spending as variable.
