This quick, no-nonsense calculator helps you answer one scary-simple question: can this make money fast enough to be worth it? Plug in your price/costs (or ARPU/churn for SaaS), slide a sensitivity control, and instantly see break-even units or months, plus a margin-of-safety readout you can pass around the team.

How this helps
Shows the break-even point and how much room you have before dipping into losses if sales or price wobble.
Assumptions
Simple, first-pass math: no taxes, financing, or overhead allocation beyond “fixed costs.” Use it as a fast screening tool.
Product Inputs
Price Sensitivity
Price: $49.00
Drag to test −50% to +50% price swings (cost held constant).
Quick Formulas
- Product break-even units = Fixed costs / (Price − Cost)
- Margin of safety = (Expected units − Break-even units) ÷ Expected units
- SaaS steady-state active subs needed = Fixed costs ÷ (ARPU × Gross margin)
- SaaS time to break-even = Month when contribution from active subs ≥ fixed costs (simulated with churn & new adds).

Tip for sanity checks
Move one input at a time and watch which KPI swings the most. That’s your lever for negotiation or redesign.
Fast break-even math is a superpower. Share your screenshot with the team, argue about the assumptions, then rerun with better inputs. Ten minutes of honest modeling beats a month of wishful thinking.
