How to Budget When Your Income Is Not Fixed

In partnership with

For freelancers, gig workers, salespeople on commission, and anyone whose paycheck varies month to month, traditional budgeting methods can feel impossible. You do not know exactly how much will hit your bank account next pay period, so how can you plan your expenses and savings? The answer is a flexible, income-averaging approach that keeps you covered when work is slow and helps you prosper when things ramp up.

Below is a step-by-step framework to build a budget that adapts to your variable income without sacrificing your financial goals.

1. Calculate Your “Bare Minimum” Expenses

Start by listing your fixed, non-negotiable costs; rent or mortgage, utilities, insurance premiums, loan payments, subscriptions, and groceries.

• Your total bare-minimum needs to determine the absolute floor of what you must earn each month.

• This number becomes your baseline: if you earn less, you tap your buffer; if you earn more, you allocate the surplus elsewhere.

2. Establish an Irregular Income Buffer

Before anything else, build a cash cushion equal to 1–2 months of your bare-minimum expenses.

• Treat your buffer like an emergency fund, only use it when your monthly earnings fall short.

• Replenish the buffer first whenever you have surplus income to maintain stability.

3. Determine Your Average Monthly Income

Review the past 6–12 months of earnings and calculate a rolling average.

• Use this average as your “planning income” each month.

• In months you exceed that average, allocate the extra toward savings, debt payoff, or buffer replenishment.

4. Prioritize and Automate Your Expenses

With your average income in mind, assign funds to categories as a priority:

• Tier 1: Essentials (bare-minimum costs)

• Tier 2: Debt payments and buffer contributions

• Tier 3: Savings goals (retirement, investments)

• Tier 4: Variable spending (dining, entertainment, discretionary)
  Automate payments for Tier 1 and Tier 2 to ensure bills and buffers are always covered.

5. Use Percentage-Based Allocations

If you prefer flexibility over fixed dollar amounts, assign percentages of each month’s actual income to different buckets:

• Fifty percent for essentials

• Twenty percent to debt and buffer

• Twenty percent to savings and investments

• Ten percent to lifestyle and fun
  Adjust the percentages based on your personal goals and commitments.

6. Plan for “High-Income” Months

Identify months when you typically earn more, seasonal work, bonuses, or big projects; and earmark those for major goals:

• Bulk debt reduction

• Investing in courses or equipment that generates future income

• Large purchases or annual expenses (insurance, taxes, subscriptions)

7. Review and Adjust Regularly

Set a recurring monthly or quarterly review:

• Compare actual earnings to your average and adjust next month’s budget percentages if needed.

• Track buffer levels and goal progress.

• Refine your bare-minimum list as expenses change.

Budgeting with an unpredictable income requires discipline and creativity, but it is entirely possible. By focusing on minimum needs, building a buffer, and planning around your average earnings, you can weather the lean months and maximize the prosperous ones. This adaptive strategy keeps you in control—no matter how your income fluctuates.

Big investors are buying this “unlisted” stock

When the founder who sold his last company to Zillow for $120M starts a new venture, people notice. That’s why the same VCs who backed Uber, Venmo, and eBay also invested in Pacaso.
