Side Hustle Income Calculator — Free Online Tool
$40 an hour sounds great — but what does 8 hours a week actually earn in a year? This side hustle calculator turns your rate and hours into annual, monthly, and weekly income projections, minus expenses.
What is the Side Hustle Income Calculator?
Side income math is deceptively simple: rate × hours × weeks. At $40/hour for 10 hours a week, that's $20,800 a year — a meaningful second income. The trap is forgetting expenses (supplies, platform fees, mileage, software) and taxes: as a 1099 earner you owe self-employment tax on top of income tax.
Use the monthly figure to set goals: does it cover the car payment? Build the emergency fund? Then sanity-check the hours against burnout — 10 'extra' hours a week is 500+ hours a year. The best side hustles eventually scale income without scaling hours linearly (products and systems, not just more hours).

Frequently asked questions
How much can I realistically earn from a side hustle?
It varies: 5 hrs/week at $30/hr is about $7,800/year; 10 hrs/week at $50/hr is about $26,000/year. Consistency matters more than the rate.
Do I pay taxes on side hustle income?
Yes — it's taxable, and if you're self-employed you'll owe SE tax too. Set aside roughly 25–30% of profit for taxes.
Should I subtract expenses in a side hustle calculator?
Absolutely — supplies, platform fees, mileage, and tools come off the top. This side hustle calculator subtracts them for a true net figure.
What's a good side hustle hourly rate?
Aim for at least 1.5–2× your day-job hourly rate, since you get no benefits, PTO, or employer-paid payroll taxes.
