Break-even = upfront cost ÷ monthly profit (revenue − running costs). It ignores taxes, your own time/labor value, and ramp-up (revenue rarely starts at full level). Add a value for your hours to judge whether the profit beats other uses of your time. Informational, not financial advice.
About this tool
Before pouring money into a side hustle, it helps to know when it pays you back. This calculator computes the break-even point — the number of months your monthly profit takes to recoup the upfront startup cost — and projects net profit over a horizon you choose. Monthly profit is your monthly revenue minus running costs, and break-even is simply startup cost divided by that profit; after break-even, the hustle is net positive. It is a quick reality check: a venture with high startup costs and thin margins may take years to break even, while a lean one can be profitable in months. The model is intentionally simple and names what it omits — taxes, the value of your own time (often the biggest hidden cost of a side hustle), and the ramp-up period where revenue starts low and builds. Putting a dollar figure on your hours is the best way to judge whether the profit is worth it versus other uses of your time. It is informational, not financial or business advice. Everything runs in your browser.

Frequently asked questions
- How is break-even calculated?
- Upfront startup cost ÷ monthly profit, where monthly profit is revenue minus running costs. A $3,000 startup with $800/month profit breaks even in about 4 months; after that, you are net positive.
- What if monthly profit is zero or negative?
- Then the hustle never breaks even as modeled — running costs meet or exceed revenue, so you keep losing money. You need to raise revenue or cut costs before it can recoup the startup investment.
- Should I count my own time as a cost?
- Yes, ideally. The biggest hidden cost of most side hustles is your hours. Multiply the time you spend by what that time is worth (your hourly rate or opportunity cost) and treat it as a running cost to see the true profit.
- Does this account for revenue ramp-up?
- No — it assumes steady monthly revenue from the start. In reality most hustles start slow and build, so real break-even is usually later than a flat projection suggests. Use conservative early-revenue figures.
- What about taxes?
- Side-hustle profit is generally taxable income (often self-employment tax too in the US). This tool shows pre-tax profit; set aside a portion for taxes and consider it when judging the real return.
- Is this business advice?
- No. It is an informational break-even estimate. For a real venture, build a fuller budget and consider professional guidance.
