The Side Hustle Math
Nobody Talks About

$25/hour sounds great until you factor in gas, taxes, and wear on your car. Here's how to calculate what you're really making.

DoorDash says you'll make $25/hour. Uber advertises $30/hour during peak times. Fiverr gigs promise $50 per project.

But here's what they don't advertise: that's not what you take home.

Let's run the real numbers on a typical DoorDash shift.

The Advertised Math

Looks decent. But we're not done.

The Actual Math

Gas costs: You drove 60 miles. Your car gets 25 MPG. Gas is $3.50/gallon. That's $8.40 in gas.

Vehicle depreciation: IRS standard mileage rate is $0.67/mile for 2024, which accounts for gas, maintenance, insurance, and depreciation. 60 miles × $0.67 = $40.20 in true vehicle costs.

Self-employment tax: You're a contractor, so you pay both sides of payroll tax. That's 15.3% off the top. $80 × 0.153 = $12.24.

Income tax: Let's say you're in the 22% federal bracket. $80 × 0.22 = $17.60. (And that's before state tax.)

You just worked for $2.49 per hour.

The Hidden Costs They Don't Mention

1. Unpaid time. That "4-hour shift" doesn't count the time you spent waiting for orders, driving to the zone, or dealing with app issues. Real time invested: probably closer to 5 hours.

2. Vehicle maintenance. Brake pads, oil changes, tire wear — all accelerated by constant driving. Budget $0.10-0.15 per mile for actual maintenance.

3. Insurance. If you're doing rideshare or delivery without commercial insurance and you get in an accident during a delivery, your personal policy won't cover it. Commercial policies run $150-300/month extra.

4. Opportunity cost. Those 4 hours could have been spent on literally anything else — including a different gig that actually pays.

When Side Hustles Actually Make Sense

Not all gigs are bad. Some legitimately pay well when you run the real numbers:

High-value, low-overhead gigs: Freelance writing, design, coding — if you're making $50-100/hour and working from home, your take-home is much closer to advertised rates.

Asset-light services: Dog walking, tutoring, consulting — minimal vehicle wear, no inventory costs, just your time and expertise.

Scale-up potential: Selling digital products, building a course, creating content — upfront work, but revenue keeps coming without linear time investment.

How to Actually Calculate Your Rate

Here's the formula:

Expenses to include:

• Mileage (use $0.67/mile or track actual gas + maintenance)
• Platform fees (Uber takes 25-30%, Fiverr takes 20%, etc.)
• Supplies (bags, phone mount, etc.)
• Additional insurance if required

Taxes to include:

• Self-employment tax: 15.3% on net income
• Federal income tax: 10-37% depending on bracket
• State income tax: 0-13% depending on state

Time to include:

• Active work time
• Wait time between gigs
• Travel to/from work zones
• Administrative tasks (tracking expenses, filing taxes, etc.)

The $15/Hour Minimum

After taxes and expenses, if you're not clearing at least $15/hour net, you're better off working literally any W-2 job. Fast food pays $15-18/hour with none of the tax complexity and vehicle costs.

"If your side hustle pays less than minimum wage after real costs, it's not a hustle — it's a hobby you pay to have."

Tools That Actually Help

Most side hustle calculators are garbage. They ask for your gross and spit out some vague percentage. They don't account for mileage, self-employment tax, or actual time invested.

We built it because we got tired of the BS. Enter your gross, your expenses, your hours. It calculates:

• Net after expenses
• Self-employment tax
• Federal + state income tax
• True hourly rate

No account required. No upsell. Just the math.

Bottom Line

Run the real numbers before you commit. If a gig doesn't clear $15-20/hour net after all costs, it's not worth your time unless you genuinely enjoy it.

Your time has value. Make sure you're actually getting paid for it.
