How to Budget on an Irregular Income
Freelancers, shift workers, and commission earners need a different rhythm. Here is the buffer-and-baseline method.
Stop budgeting for an average month
Averages describe years, not months. A budget built on your average income breaks in every below-average month — and most months are below average when a few big ones pull the mean up.
Build a baseline
Look back twelve months and take your lowest month. That is your baseline. Build a budget that covers essentials on that figure: housing, food, utilities, transport, insurance, minimum debt payments.
Create an income buffer
When a good month arrives, do not expand the budget. Park the surplus in a buffer account. The goal is one full baseline month sitting in the buffer, then two. Once you are a month ahead, you budget last month's income — which is a fixed, known number.
Order your priorities in advance
Write a list before the money arrives: essentials, tax set-aside, buffer top-up, debt, goals, lifestyle. When a large payment lands, work down the list instead of improvising.
Do not forget tax
If tax is not deducted for you, move a fixed percentage of every payment into a separate account the day it arrives. Treat it as money that was never yours.
