How much can you realistically earn from a side hustle?

Gross revenue minus expenses minus self-employment tax minus unpaid hours = real income. Most side hustles report a number 2-3× their actual hourly rate.

How the math works

Four layers of subtraction between gross revenue and your real hourly rate:

  1. Direct expenses: materials, supplies, platform fees, payment processing, software, marketing.
  2. Self-employment tax: 15.3% on net SE income.
  3. Income tax: federal + state at your marginal bracket (typically 22-32% combined for someone with a day job).
  4. Total hours: billable + admin + marketing + customer service + learning.

Output: real take-home and effective hourly rate. Most side hustles report a number 2-3× their actual hourly rate because they only count "doing the work" hours and ignore the other 30-40%.
