The idea
Some large costs are entirely predictable: school fees, annual insurance, festival and holiday spending, a planned trip, replacing a phone or appliance at the end of its life, a vehicle service. Yet because they arrive in one lump, they often feel like emergencies and end up on credit.
Planning for them is simple arithmetic: estimate the cost, count the months until it is due, and set aside the monthly share. A calendar of the year’s large costs, written once, prevents most of these shocks. This is the same idea as a sinking fund, applied across the whole year.
Why it matters
Predictable large costs cause a surprising share of household debt. Planning for them keeps credit for genuine emergencies — or not needed at all.
A real example
- The situation
- Every school year, Aigerim borrows to cover fees and uniforms for her two children.
- What happened
- She adds up last year’s school costs, divides by ten months and saves that amount from each salary. The next school year starts without a loan.
- The takeaway
- Treating a yearly cost as a monthly one removed the need to borrow.
How people actually behave
People think month to month, so costs that arrive once a year slip out of the plan until the month they land.
Common mistakes
- Treating yearly costs as surprises every year.
- Using the emergency fund for predictable costs.
- Starting to save too late for the size of the cost.
Questions to think about
- What large costs will you face in the next twelve months?
- Which of them usually ends up on credit?
Try it: The year-ahead calendar
- Write each month of the next year and add every large cost you expect.
- For each cost, calculate the monthly amount to save.
- Add the total to your budget as one line.
