How do I budget with irregular income?

Pay yourself a fixed salary from a separate account: set it at roughly the 25th percentile of your recent months (a floor most months clear), keep a buffer sized to your actual swings (2–6 months of essential costs), and bank everything above the salary in good months. Budgeting to your average month is the classic mistake — the average month rarely happens.

How big should my emergency fund be with variable income?

Scale it to your volatility, not a flat rule: if your months swing within ±15% of average, 2 months of essentials is workable; ±15–35% wants about 3; bigger swings want 4.5–6. The buffer’s job is to make your low months feel like normal months.

What income should I use to qualify for a mortgage as a freelancer?

Lenders typically average your last two years of self-employed income from tax returns — and use the lower year if income declined. Your safe monthly salary here is a good preview of what a cautious underwriter will see, and it is usually well below your best months.

Steady Paycheck (Variable Income)

For freelancers, tipped workers, sellers, and seasonal earners: paste your last months of income and get the salary you can safely pay yourself, how big a buffer your actual swings require, and which months were spikes to bank rather than spend. The pay-yourself-a-salary method every advisor teaches by hand, as a calculator.

The numbers

Safe monthly salary: 2,750; pay yourself this, every month, regardless
Average month: 3,667; for contrast — do not budget on this
Lowest month: 2,100
Income swing: ±32%; typical deviation around your average
Buffer target: 7,500; 3.0 months of essentials at your volatility

The operator’s read

Worth knowing

2 of your 6 months came in below the safe salary — the buffer, not the average, is what makes those months feel normal. In months above 4,583 (you had 2), bank everything above the salary; that is how the buffer fills itself.

Caution

No buffer yet: at your ±32% swings, the target is 7,500 (3.0 months of essentials). Route every dollar above the safe salary there first — at your average income that is roughly 917/month, filling it in about 8.2 months.

Methodology

Safe salary = the 25th percentile of your entered months (linear interpolation): a floor that 3 of every 4 months clear. Budgeting to the average fails for volatile income because the average month is not a typical month — US Financial Diaries research found households swing 25%+ off their own average more than 5 months a year, with dips averaging −45%.

Income swing = coefficient of variation (standard deviation ÷ mean of your months, population form). The buffer target scales with it: ±<15% → 2 months of essentials, ±15–35% → 3, ±35–60% → 4.5, above → 6. Steadier income needs less cushion; spikier income needs more — a flat "3 months" rule ignores exactly the thing that makes variable income hard.

Spike months are months more than 25% above your average — the pay-yourself-a-salary method treats them as buffer deposits, not raises.

All computation happens from the numbers you paste; nothing is stored. This is a one-time snapshot — the hard part of variable-income budgeting is repeating it as each month lands.
