U.S.-oriented salary estimate
Tax Year
Current assumptions
Use Case
Planning estimate, not payroll advice
Enter the gross income or sales generated by the side hustle before expenses, fees, or taxes.
Estimate annual costs such as supplies, software, equipment, mileage, or advertising.
Use this for marketplace fees, payment processor fees, booking commissions, or similar costs.
Use a flat planning estimate for taxes on the remaining profit after expenses and fees.
Enter the total hours you expect to spend on the side hustle for the same period as the revenue estimate.
This side hustle profit estimator is built for practical work-income planning. It starts with gross revenue, subtracts business expenses and optional fees, applies a simplified tax assumption, and then shows what remains as estimated after-tax profit and effective hourly profit. The goal is to help you see whether a side hustle is only generating sales or actually producing usable income for the time you spend on it.
How It Works
Side Hustle Profit Method
Profit = Revenue - Expenses - Fees; After-Tax Profit = Profit x (1 - Tax Rate); Hourly Profit = After-Tax Profit / Hours WorkedThe estimator subtracts business costs from revenue, applies a simple tax estimate to the remaining profit, and then divides the result by total hours worked to show what the hustle is really paying you.
Revenue is the top-line amount earned before expenses, fees, or taxes.
Estimated profit is calculated by subtracting business expenses and optional fees from revenue.
Estimated after-tax profit applies a flat planning tax rate to that remaining profit so you can see a more realistic keep amount.
Effective hourly profit divides after-tax profit by the hours worked, which helps reveal whether a side hustle is paying well for the time invested.
Important Notes:
- •This tool is a practical planning estimator, not bookkeeping or tax software.
- •It assumes a flat tax rate for simplicity rather than modeling self-employment tax, credits, local taxes, or entity-specific rules.
- •Use the same time period for revenue, expenses, fees, and hours worked so the result stays consistent.
- •If you leave out major expenses or undercount your hours, the effective hourly profit can look better than reality.
- •This first version is intentionally simple so the decision signal is easy to understand before moving into deeper tax or business planning.
Worked Example
A worker earns $18,000 from a side hustle over the year, spends $3,500 on business costs, pays $900 in fees, expects a 24% tax rate, and spends about 420 hours on the work.
Inputs:
- revenue:18,000
- business Expenses:3,500
- optional Fees:900
- estimated Tax Rate:24
- hours Worked:420
Result:
The estimator shows about $13,600 in pre-tax profit, about $10,336 in after-tax profit, an effective hourly profit of about $24.61, and a retained percentage of about 57.4%.

- Salary Increase vs Side Hustle Income
Use a salary increase workflow when your strongest income lever is improving your primary job compensation. Use a side-hustle workflow when your stronger lever is building extra after-tax profit outside your job. The better path depends on how much income each option adds, how much time it requires, and how much of the money you actually keep after costs and taxes.
