97 sales a month to break even
That's $30,555 a month, or $366,660 a year, before you make a penny.
The math
- $315 per sale − 15% variable cost = $268 contribution
- $25,754 fixed costs ÷ $268 = 97 sales
Every sale past 97 adds $268 straight to the bottom line. That is why filling quiet hours is worth more than it looks — the fixed costs are already paid.

Common questions
