Side Hustle Hourly Rate: How to Calculate Your Real Profit

Your real side hustle hourly rate is what you keep after expenses, self-employment tax and income tax, divided by every hour the business takes, not just the hours spent making or selling. In the worked example below, a side business that looks like $80 an hour on production time works out to $18.78 an hour once everything is counted.

The Formula

Real hourly rate = (revenue − expenses − self-employment tax − income tax on the profit) ÷ total hours.

How Self-Employment Tax Works on a Side Hustle

The IRS says you usually owe self-employment tax if your net earnings from self-employment are $400 or more for the year. The tax is 12.4% for Social Security and 2.9% for Medicare, 15.3% in total, and "generally, the amount subject to self-employment tax is 92.35% of your net earnings." An employee splits these taxes with the employer; self-employed people pay both halves.

Two deductions soften it. You can deduct half of your self-employment tax when figuring adjusted gross income, and the qualified business income (QBI) deduction can take off up to 20% of your business profit (after that half-SE-tax deduction), capped at 20% of taxable income. If your day job's wages already reach the Social Security wage base ($184,500 for 2026), the 12.4% part stops, but the 2.9% Medicare part still applies.

For comparison, the federal minimum wage has been $7.25 an hour since July 24, 2009, and many states set a higher one. A better comparison for most people is the after-tax rate of a part-time job they could realistically get locally, since that is the alternative use of the same hours.

Hours People Leave Out

• Sourcing and buying supplies, including trips to pick them up.
• Customer messages before and after the sale.
• Packing, shipping and returns.
• Photos, listings and social posts.
• Bookkeeping and taxes, including quarterly estimates.

Ways to Raise the Real Rate

There are three levers: price, cost and hours. In the example, cutting the non-production time from 15 to 10 hours a month (for example, by batching packing and answering messages twice a day) brings total hours to 240 a year and the real rate to $5,632.65 ÷ 240 = $23.47, with no change in sales. Tracking a month of time by activity usually shows which lever is cheapest to pull.

• Price: a small price rise flows almost entirely to profit, though tax takes its share of the increase.
• Cost: compare platform fees across marketplaces and your own site, and buy materials in larger batches if you have steady demand.
• Hours: templates for listings and replies, and set days for shipping.

Records That Make This Easy

• A separate bank account or card for the business, so revenue and costs don't need to be picked out of personal spending.
• Receipts for every expense, kept digitally in one folder.
• A mileage log with date, purpose and miles for each business trip.
• A simple time log by activity for at least one month a year, which gives you the hours half of the formula.

Driving for the business is also a real cost. The IRS business standard mileage rate for 2026 is 72.5 cents a mile for January through June and 76 cents from July 1, which gives a fair per-mile figure to subtract even if you choose to deduct actual expenses instead.

What This Doesn't Cover

This guide doesn't include state or local income tax, sales tax, the IRS rules on whether an activity is a hobby or a business, or the underpayment penalty if you skip estimated payments. Our guide to self-employment tax and quarterly payments covers that last point. For your own return, a CPA or enrolled agent can confirm which deductions apply.
