What is zero-based budgeting?
Zero-based budgeting (ZBB) means allocating your income so that income minus all allocated amounts equals zero. Every pound is assigned — to bills, food, savings, fun money, debt repayment. Nothing is unaccounted for.
The "zero" does not mean spending everything. Savings and investments are allocated categories too.
How to set it up
1. Write down your monthly income. 2. List all your spending categories (bills, food, transport, fun, savings, etc.). 3. Allocate amounts to each category until income minus total allocations equals zero. 4. Track actual spending against categories each month.
Why it works
ZBB eliminates "mystery" spending — money that disappears without you noticing. By assigning every pound, you make conscious decisions about priorities rather than discovering at the end of the month that money has vanished.
The main challenge
It requires active tracking. If you spend more in one category, you must move money from another. This is the point — it forces real-time decisions about priorities. Some people find this empowering; others find it stressful.
