Why last year’s budget stops working
Inflation means the same things cost a little more each year. A few percent sounds small, but it compounds — and some categories like food, school fees, rent and healthcare often rise faster than the headline rate. A budget that was comfortable last year can feel tight this year without you changing anything.
Spot it in your own spending
- --Compare the same month year on year — groceries, utilities, school fees, insurance premiums.
- --Watch for shrinkflation — the same price for a smaller pack. Check the price per kg or litre, not the pack price.
- --Notice which categories grew even though your habits didn’t.
Adjust once a year
- --Raise budgets category by category, based on your own spending — not one flat percentage.
- --Raise your savings goals too. A target set five years ago buys less today (saving for a house).
- --Plan for annual increases — rent clauses, school fees and premiums usually rise every year (school fees budget).
- --Shop smarter on staples — compare unit prices, buy in bulk what you use, and cut waste (saving on groceries).
