Budgeting for an Irregular Income

When your income bounces around, a fixed monthly budget can break. A better system is a baseline budget funded by a minimum expected income, plus a percentage plan for months that beat the baseline.

Step 1: find your baseline

Look at the last 12 months of income. Drop the highest month, then average the rest. That conservative average is your baseline. Your monthly essentials must fit within this number.

Example: 12-month incomes were $3,000, $5,500, $4,000, $2,800, $6,000, $4,500, $3,200, $5,000, $4,800, $3,500, $5,200, $4,600. Drop the $6,000 month. The average of the remaining 11 is about $4,236. Call it $4,200 for safety.

Step 2: set the floor

Your rent, groceries, insurance, minimum debt payments and a small emergency contribution must total less than $4,200. If they do not, cut expenses or increase your minimum income by taking more predictable work.

Step 3: split the surplus

In months above baseline, send the surplus to:

• 50% to an emergency fund until it is full
• 30% to tax withholding or a tax savings account
• 20% to discretionary goals or extra debt payments

This system protects your essentials in bad months and accelerates your reserves in good months.
