These are the ad hoc, seasonal, or occasional expenses that can otherwise catch you out.
Examples:
Holidays
Annual insurance
Car servicing or repairs
Gifts
School costs
Home purchases
One-off family expenses
How it works
You create categories for the irregular costs you expect over time and assign a budget to each one.
Example:
Holiday £1,200
Annual insurance £600
Gifts £300
We total these together to create your overall Non-Monthly budget.
Why this matters
Many budgets fail because one-off costs get mixed into normal monthly spending.
If a holiday or annual bill lands in the same month as groceries and eating out, it can look like you’ve overspent when really it was a planned irregular cost.
By separating Non-Monthly costs, your everyday budget stays clearer and more realistic.
Categories
Non-Monthly is category-led, which means each cost should sit in a category.
Examples:
Holiday
Car
Insurance
Gifts
This helps keep your budget organised and makes it easier to see what upcoming costs you’re planning for.
During the month
When one of these costs happens, it counts against your Non-Monthly budget rather than your everyday Flexible budget.
That helps avoid big one-off purchases distorting your normal monthly picture.
You will need to re-categorise those transactions into the correct bucket as they arrive
Why this helps
Non-Monthly budgeting helps you:
Prepare for costs before they arrive
Reduce surprise bills
Keep monthly spending clearer
Feel more in control year-round
Avoid “how did that happen?” months
