The 50/30/20 budget, rewritten for irregular income
Percentages still work when paychecks do not. Base them on a low month, park the surplus, and stop rebasing your life every time a good invoice lands.

Use the low month as the base
List the last six months of take-home pay. Circle the lowest one you could live through again, not the average. Average includes a spike you will spend as if it repeats. The low month is the salary you budget against.
Needs are housing, utilities, groceries, transport, insurance, minimum debt payments — aim near fifty percent of that low month. Wants near thirty. Savings and extra debt payments near twenty. If needs already eat seventy percent of the low month, the fix is the needs, not a tighter wants category.
What to do with a bigger check
When a month comes in higher, pay the budgeted life first — the same transfer amounts as the low month. The surplus has an order: top up the emergency fund if it is below one paycheck, then extra debt, then a want you name in advance. Unnamed surplus becomes delivery and tabs.
Move the surplus the day it lands. Waiting until the end of the month is how it blends into spending.
A thin month
If a month lands below the base, wants shrink first, then the savings transfer, and needs stay. That is the point of basing the plan on a low month: it should be rare. If two months in a row miss the base, the base was a wish. Recalculate from the new low and adjust one need you can actually change.
