Find your baseline
Look at the last twelve months and take the lowest month, or the average of the three lowest. That is your baseline — the figure the budget is built on. Anything above it is a surplus with a job, not spending money.
Pay yourself a salary
Route all income into a holding account. On a fixed date each month, transfer your baseline amount to your everyday account. You then budget like a salaried person while the holding account absorbs the volatility.
Split every payment as it arrives
- Set aside tax immediately if you are self-employed.
- Top the holding account up to next month's salary.
- Send a fixed percentage to the income smoothing buffer.
- Only then allocate anything to goals or extras.
Build a larger emergency fund
Where a salaried household might target three months of essential costs, variable earners are better served by six. The fund is covering both emergencies and income gaps.
Separate business and personal money
Mixed accounts make it impossible to know what you actually earn. Separate accounts also make tax season dramatically less painful.
Plan for the lean season
Most variable incomes have a predictable rhythm. Identify your two weakest months and over-fund the buffer in advance rather than reacting when they arrive.
