$16K startup to $90K/month — calculate YOUR side hustle profit
Did our AI summary help? Let us know.
The gig economy is booming in 2026 with 57+ million Americans freelancing. But most side hustlers overestimate their earnings by ignoring self-employment tax (15.3%), business expenses, and the true cost of their time. This calculator shows your real profit after all deductions.
Ready to run the numbers?
Why: Most side hustlers overestimate their earnings. Gross revenue looks impressive until you subtract self-employment tax (15.3%), business expenses, mileage, home office, and equipment. The true take-home is often 40-60% of what you think. Stories of $16K startups turning into $90K/month often ignore the tax bite and time cost — this calculator reveals your real profit.
How: The calculator takes gross revenue, subtracts direct costs, operating expenses, mileage deduction (67.5¢/mile), home office (simplified $5/sq ft or actual method), and equipment depreciation (50% first-year). It then applies self-employment tax (15.3% on 92.35% of net profit), federal income tax with QBI deduction, and outputs true take-home profit, effective hourly rate, and profit margin.
