Find out what you really keep from your side hustle after taxes. This calculator computes the self-employment tax (15.3%) and additional federal income tax on your side hustle earnings, accounting for your existing W-2 income and tax bracket. See your true hourly rate and monthly net income.
Side hustle income — Uber driving, Etsy sales, freelance work, consulting, content creation — has become a substantial part of many Americans' financial lives. But the tax treatment is harsher than most beginners expect. Side hustle income gets stacked on top of W-2 wages for income tax purposes (often at a higher marginal bracket than your day job's effective rate) AND incurs the 15.3% self-employment tax that W-2 employees only pay half of (their employer pays the other half). The combined tax burden on side hustle dollars is typically 25-40% — meaningfully higher than the same gross income earned via a regular paycheck.
The math: a $2,000/month side hustle generating $24,000/year of additional revenue might net only $14,000-$17,000 of take-home after federal income tax, state tax, and self-employment tax. The "effective hourly rate" of side hustle work — total net after-tax pay divided by total hours including unbillable admin time — is often 50-65% of the gross hourly rate. This isn't a reason to skip side hustles, but a reason to do honest math before assuming the gross income is the spendable income.
This calculator estimates net take-home from a side hustle given your existing W-2 income, side hustle revenue, business expenses, and filing status. It accounts for the self-employment tax stack-on and the marginal income tax bracket impact. Use it to evaluate whether a planned side hustle is worth the time, to plan quarterly estimated tax payments, or to set realistic income expectations from gig work.
$1,500/mo gross ($18K/year), $200 expenses ($2.4K), $42K W-2 income, single. Net SE income: $15,600 SE tax: $2,205 Income tax bracket (combined): 22% Additional income tax: ~$3,432 Total federal tax: ~$5,637 State tax (5%): $780 Net take-home: $18,000 − $2,400 − $6,417 = $9,183 Effective tax rate on gross: 49% The side hustle adds about $9K of net annual income — equivalent to about $173/week extra. Real but smaller than the "$1,500/month" gross suggests.
$5,000/mo gross ($60K/year), $500 expenses ($6K), $130K W-2 income, married jointly. Net SE income: $54,000 SE Tax: $7,632 Combined income pushes into 24% bracket (was 22%) Additional income tax: ~$13,000 Total federal tax: ~$20,632 State tax (5%): $2,700 Net take-home: $60,000 − $6,000 − $23,332 = $30,668 Effective tax rate on gross: 51% The side hustle adds ~$30K of net annual income on top of $130K W-2. Material — but the higher marginal tax bracket means the percentage take-home is lower than the entry-level example.
$500/mo gross ($6K/year), $0 expenses, no W-2 income (full-time student or other situation). Net SE income: $6,000 SE Tax: $848 (if above $400 threshold, which $6K is) Standard deduction wipes out income tax entirely (no W-2 income, standard deduction $15K > side hustle income). No state tax (income below threshold in most states). Net take-home: $6,000 − $848 = $5,152 Below the income tax threshold, only SE tax applies. For low-income side hustlers, the tax burden is much lower than higher-income comparison cases.
Use this calculator when starting a side hustle, evaluating whether a side hustle opportunity is worth the time investment, planning quarterly estimated tax payments, or pricing services to net target hourly rates.
Pair with: freelancer-quarterly-tax (for the detailed quarterly tax planning), self-employment-tax (for the SE tax math specifically), salary-to-hourly and hourly-to-salary (for rate-setting), and pay-raise (for evaluating side hustle vs. asking for a raise).
For freelance and contract workers transitioning from W-2 employment to full-time self-employment, this calculator shows the tax math that suddenly applies to all income (not just the marginal "extra" income). Full-time self-employment requires charging 30-50%+ more than equivalent W-2 salary to break even on take-home, after factoring in self-employment tax, lost employer benefits (healthcare, retirement match), and lost paid time off.
