Effective tax rate calculator for freelancers

Your effective rate is lower than your bracket. That changes your pricing.

"I'm in the 22% bracket" tells you the tax on your next dollar. It does not tell you what you actually pay on all your income — and for a freelancer the gap is large, because self-employment tax sits on top.

This calculator blends self-employment tax and federal income tax into one effective rate, so you know how much of every dollar you bill is really yours.

Marginal and effective are not the same number

When people say "I'm in the 22% bracket," they mean their marginal rate — the tax on the next dollar they earn. But their effective rate is what they actually pay across all their income, once the 10% and 12% slices at the bottom are included. For a freelancer the gap is even wider, because self-employment tax sits on top of income tax as a roughly fixed percentage rather than a bracket.

This calculator combines the two into one blended number: your real federal rate on the money you bring in. That figure is far more useful for pricing and saving than the bracket you quote at dinner.

Why the blended rate matters for freelancers

A W-2 employee sees withholding that roughly tracks their effective rate. A freelancer sees nothing withheld, and is then surprised by the April bill. Knowing the effective rate — say 25% rather than the 22% bracket they had in mind — is what tells you to move 25% to a tax account on every payment, not 22%. The missing few percent is almost entirely self-employment tax.

It also reframes pricing decisions. If your effective rate is 25%, then billing an extra $1,000 leaves you about $750 wealthier after federal tax. That is the number to weigh against the cost of saying no to a project, not the marginal bracket.

How self-employment tax stacks on top

Self-employment tax is 15.3% on 92.35% of your net profit, and it applies before income tax is computed. It is not itself progressive in the way income tax is, though the Social Security portion caps out at the wage base ($176,100 for tax year 2025). Above that, only the 2.9% Medicare portion continues, plus an extra 0.9% Medicare surtax once profit passes $200,000 for single filers.

Because the SE tax is calculated first and half of it is deductible, the order of operations matters. This calculator does it in the right order: SE tax, then the deductible half reduces adjusted gross income, then income tax on what remains.

What lowers your effective rate

• Retirement contributions. SEP IRA and Solo 401(k) contributions are above-the-line deductions: they reduce AGI and therefore both SE and income tax. At a 25% blended rate, a $10,000 contribution saves about $2,500 in tax.
• Half of SE tax is already deducted for you — no action needed.
• The QBI deduction. Many freelancers qualify for a 20% deduction on qualified business income, which this simplified calculator does not model. If you qualify, your effective rate will be lower than shown.
• Standard vs itemized. The calculator uses the standard deduction ($15,000 single / $30,000 joint for 2025). If you itemize higher, your taxable income and rate drop further.
