What should I use as my 'opportunity cost' hourly rate?

Your opportunity cost is the best alternative use of those hours. If you could pick up extra shifts at your day job, use your overtime or standard hourly rate. If you could do freelance work in your primary profession, use your market freelance rate. If the hours would genuinely go to rest or family time, consider what that's worth to you subjectively — many people use $15–20/hour as a baseline. If your side hustle doesn't beat this number after taxes, the math says it's not worth the financial tradeoff (though non-financial reasons like passion or learning may still make it worthwhile).

How do I calculate my side hustle expenses?

Include everything that costs money because of the hustle: materials and supplies, software subscriptions, professional services, platform fees (Etsy listing and transaction fees, Fiverr percentage, etc.), equipment depreciation, and any portion of your phone, internet, or home office used for the hustle. For vehicle-based hustles, use the IRS mileage rate. A good starting point is to list every expense from the last month and multiply by the fraction attributable to the side hustle.

Do I have to pay self-employment tax on all side hustle income?

If your side hustle is structured as a sole proprietorship or single-member LLC (or if you receive a 1099), you're generally responsible for self-employment tax on net profit. SE tax is 15.3% on 92.35% of net income — covering the employee and employer share of Social Security and Medicare. This is on top of your regular income tax. However, you can deduct half of SE tax on your Form 1040, which reduces your income tax slightly. Certain structures (like an S-Corp election) can reduce SE tax at higher income levels.

Is a side hustle earning less than my opportunity cost ever worth it?

Sometimes, yes. Non-financial reasons that can justify a lower net hourly rate include: skill development (learning new capabilities that will eventually pay more), portfolio building (especially for creative or technical freelancers), social impact (work you find meaningful), or genuine enjoyment of the work. The calculator flags whether you're above or below your opportunity cost, but the decision is ultimately yours — the goal is to make the comparison explicit rather than invisible.

Is your side hustle actually worth your time?

What This Does

Every side hustle sounds good in theory. You make extra money on your own schedule. What's not to like? The problem is that most people evaluate a side hustle by its gross revenue — not by what it actually pays per hour after every cost and tax is counted. Opportunity cost is the real comparison. When you spend 10 hours per week on a side hustle, you're not just earning that income — you're choosing not to use those 10 hours for something else. Rest, family time, skill development, a second part-time job, or simply relaxation all have real value. If your side hustle nets $12/hour but your day job would pay you $18/hour in overtime — or if freelancing in your core skill would pay $30/hour — then you may be underselling your time. This calculator models the full picture for any side hustle: gross income minus business expenses, then minus self-employment tax (if you're a 1099 worker) and income tax, leaving your real take-home per hour. It then compares that to your stated opportunity cost — what you could earn per hour in your best alternative — and tells you whether the side hustle beats, matches, or falls short of that benchmark. You can load common side hustle presets (freelance writing, Etsy, dog walking, tutoring, delivery, social media management, photography, cleaning) for a starting point, then customize with your own numbers. The output includes a sensitivity table by weekly hours and a break-even target for what gross earnings are required to match your alternative.

When Should You Use This?

→Deciding whether to continue or quit a side hustle based on actual hourly return
→Comparing two side hustle options against each other and your alternative
→Evaluating a new side hustle idea before committing hours to it
→Negotiating freelance rates — know the minimum that makes the engagement worthwhile
→Tax planning — see how much of side hustle revenue actually reaches your pocket

Example Scenario

Priya teaches online tutoring 8 hours per week at $45/hour, earning $360/week gross. After $20/week in supplies and software, she has $340 net before tax. As a 1099 contractor she owes SE tax, and at her marginal rate the weekly tax is about $90. Take-home: $250/week, or $31.25/hour net. Her opportunity cost is $28/hour — what she'd earn doing additional consulting work. Her tutoring rate beats her alternative by $3.25/hour and she enjoys it, so the verdict is clearly "worth it." By contrast, when she ran Etsy at the same hours for $220/week after supplies and time invested in photography, the calculator showed $15.40/hour net — clearly below her alternative.
