Budgeting on Irregular Income: The Baseline Month Method

Freelancers, gig workers, commission sales and seasonal jobs share one problem: the bills are monthly, the income is not. A budget built on an average month breaks the first time a lean month arrives.

Step 1: find your baseline

Look at the last 12 months of take-home income and take the lowest month (or the average of the lowest three). That is your baseline, not the average.

Step 2: build the budget on the baseline

Fit essentials into the baseline: housing, utilities, groceries, insurance, minimum debt payments, transport. If essentials do not fit, that is the first problem to solve.

Step 3: a holding account

Pay all income into one holding savings account. Each month, transfer the same 'salary' to your checking account. Good months refill the holding account; lean months draw it down.

Step 4: decide in advance what extra money does

Agree on an order for anything above baseline, for example:

  1. Tax set-aside (self-employed people often keep 25-30% aside for income and self-employment taxes; check your own rate).
  2. Holding account buffer until it covers 2-3 months of baseline.
  3. Debt payoff or savings goals.
  4. Fun money.

Example

Monthly income over a year ranged from $2,800 to $6,500, averaging $4,300. Baseline: $2,800 after tax set-aside. Essentials: $2,400. The holding account smooths the rest, and in a $6,500 month, the extra goes down the list above instead of into spending.
