Freelance math: what your salary actually costs

Freelancing looks easy on a spreadsheet. No commute, no boss, just your rate. You made $100k salary, so charge $150/hour and you're done.

Not how it works. The math is sharper than you expect. Your lifestyle costs 30-50% more as a freelancer than you earned as an employee. This is the accounting you'll do too late.

Your salary cost your employer much more

Your $100k salary cost your employer $130-140k all-in. Benefits, payroll taxes, workers comp, unemployment insurance. All invisible to you. All real.

Freelance, you pay all of it. To match your old take-home, you need to bill $155-180k gross. That's 55-80% more billing for the same lifestyle.

Self-employment tax is 15.3%

Employee? You paid 7.65% (SS + Medicare). Employer matched it. Gone from your check, they handled theirs.

Freelancer? You pay both halves. 15.3% on first $168,600 (2024). Above that, still 2.9% Medicare with no cap. Quarterly payments.

Half of SE tax is deductible, but it's just a deduction, not a credit. In 24% bracket, that's worth about 3.6%. You owe the other 11.7%.

Real number: $60k net income = $8,478 in SE tax. After the deduction and federal income tax, you're losing 25-30% of income before state taxes hit.

Ramp-up takes 3-6 months

Most new freelancers need 3-6 months to fill their roster. You can't bill 40 hours/week on day one. That's not failure. That's how it works.

For 3-6 months, you're burning runway with zero income. Start in January, your first real paycheck hits April or June. You've burned 4-6 months of expenses.

You need 6-9 months of runway minimum. 3 months to survive the ramp, 3-6 months to get your first real paycheck. Not 3 months total.

You're now a business. It costs money.

• Liability insurance: $500-2,000/year. Non-negotiable if you touch client data.
• Software: Project management, invoicing, accounting. $100-300/month if organized.
• Accounting: DIY software = $0-200/year. Professional bookkeeper = $1,200-3,600/year. You'll want the pro.
• LLC formation: $50-800 one-time. Most contracts want it.
• Professional development: Courses, certs, conferences. $1,000-3,000/year to stay current.

Total: 5-10% of gross freelance income if careful, 15-20% if not. Deductible. Still real cash out.

Net-30 and net-60 delays kill startups

Clients don't pay on delivery. Net-30 is standard. Net-60 is common. You bill January, money hits March or April. Rent is due February 1.

You need extra cash buffer just for payment delays. Monthly burn $4,500, clients on net-60? You need $9,000 extra in the bank.

New freelancers miss this. Invoice goes out, work feels done. Money isn't there yet.

The billing floor is higher than you think

Your $80k salary needs $110k+ in gross freelance billing just to land in the same place. And that's assuming full utilization immediately (you won't be at full utilization).

At 70% utilization (21 billable hours per week), a $110k target means $100/hour effective rate. Your market rate is $75? You're underwater before you start.

People anchor to old salary, not to lifestyle cost. That's the mistake.

The upside is real, but get there first

Once profitable, freelancing scales. No boss. Raise rates, take bigger clients, build products. Income ceiling is much higher than employment.

Getting there requires 9-12 months of runway, strong discipline, and a bigger network than most people have. If you have that, freelancing makes sense. If you're betting on it working out, the risk is real.
