When to use this calculator
Use this side hustle income calculator to estimate monthly and annual profit after expenses and tax reserve. It is useful for deciding whether a side project is producing meaningful take-home income.
Formula
Take-home side income = (monthly revenue - monthly expenses) x (1 - tax reserve rate)
- Monthly revenue is gross side hustle income.
- Monthly expenses reduce profit.
- Tax reserve rate estimates money set aside for taxes.
Worked example
For $2,000 monthly revenue, $400 monthly expenses and a 25% tax reserve, the calculator estimates $1,200 monthly take-home side income after reserve.
Common mistakes
- Counting gross revenue as profit.
- Forgetting platform fees, mileage, supplies or software.
- Ignoring tax obligations because income is part-time.
