Side Hustle Break-Even Calculator

Monthly Profit is calculated purely from ongoing revenue and expenses -- Hourly Revenue times Hours Per Week, minus Monthly Expenses, minus tax on what remains. Startup Cost is a one-time, sunk investment that doesn't recur every month, so it plays no role in the profit calculation itself. It only enters the picture afterward, when Break-Even Time divides that one-time cost by your recurring Monthly Profit to see how many months of profit it takes to recoup it.

Break-Even Time shows 'Never' whenever Monthly Profit is zero or negative -- meaning your monthly revenue, after subtracting expenses and taxes, isn't enough to generate any real profit at all. In that situation, no amount of additional time will recoup the Startup Cost, since there's no positive monthly profit accumulating toward it. Raising your Hourly Revenue, working more hours, or cutting Monthly Expenses are the levers that turn a 'Never' into a real break-even timeline.

Worth It compares your Effective Hourly Rate -- Monthly Profit divided by the actual hours you worked that month -- against your stated Opportunity Cost Per Hour, which represents what you could otherwise earn with that same time. A side hustle can show a solidly positive Monthly Profit and still fail this comparison if the hourly return on your time is lower than what you'd earn doing something else, which is exactly the scenario this second check is designed to catch.

A year has 52 weeks, and 52 divided by 12 months equals approximately 4.33 -- using this figure instead of a flat 4 avoids systematically understating monthly revenue and expenses, since a year genuinely contains more than 48 weeks. Using exactly 4 weeks per month is a common simplification elsewhere, but it quietly shorts every monthly total by roughly 8% compared to a true annual average.
