Why Expense Volatility Matters as Much as Income
Everyone obsesses over income volatility—and for good reason. But freelancers also face expense volatility: quarterly tax bills, health insurance premium jumps, equipment failures, and surprise business expenses.
Irregular expenses can blow up your emergency fund just as fast as income drops.
The Hidden Expense Spikes Freelancers Face
- Quarterly estimated taxes: $3k–$8k payments every 3 months
- Health insurance premiums: Annual increases of 10–30%
- Equipment failures: Laptop dies, camera breaks, car repairs
- Professional expenses: Software renewals, certifications, conferences
- Business expenses: Contractor payments, marketing costs, legal fees
Salaried employees have steady expenses (mostly). Freelancers have both irregular income and irregular expenses—a double volatility punch.
How to Factor Expense Volatility Into Your Buffer
Step 1: Track 12 months of expenses to identify spikes and patterns.
Step 2: Separate recurring vs. irregular expenses:
- Recurring: Rent, insurance, subscriptions
- Irregular: Taxes, equipment, health emergencies
Step 3: Add a volatility buffer—typically 10–20% on top of average monthly expenses—to cover spikes.
