Break-Even Point
The point where total revenue equals total expenses — the moment a company stops losing money and begins generating profit.
What is Break-Even Point?
Break-even is the inflection point where your revenue covers all your expenses. Above break-even, you're profitable. Below it, you're burning cash.
For startups, break-even can be calculated at the unit level (when does one customer become profitable?) or at the company level (when does total revenue cover total expenses?). Company-level break-even is the more important milestone for survival.
The break-even point can be expressed as a date ("we'll break even in March 2027"), a revenue target ("we break even at $100K MRR"), or a unit count ("we break even at 500 customers paying an average of $200/month").
Why it matters
Break-even is the finish line for cash survival. Once you cross it, your runway becomes infinite — you no longer need external capital to keep the lights on.
Knowing your break-even point is essential for fundraising planning. If you're 6 months away from break-even with 9 months of runway, you might not need to raise at all. If you're 18 months away with 12 months of runway, you know you need to either raise capital, cut costs, or accelerate revenue.
Formula
Break-Even Revenue = Total Fixed Costs / (1 - Variable Cost Ratio) Or simply: Break-Even Point = when Total Revenue = Total Expenses
Example
Monthly expenses: $80,000 (mostly fixed — payroll and tools). Variable costs per customer: $50. Average revenue per customer: $250. Contribution per customer: $200. Break-even customers = $80,000 / $200 = 400 customers. At 300 customers currently, you need 100 more to break even.
How RunwayCal helps
RunwayCal's revenue model and cash trajectory chart show when your projected revenue will exceed expenses — your projected break-even date. Scenario modeling lets you test what changes would move that date closer.
Common mistakes
- 1Assuming expenses stay flat as you grow (they usually increase with headcount and infrastructure)
- 2Not considering that break-even can move as you add costs (hiring to support growth pushes break-even further out)
- 3Celebrating break-even for one month without confirming it's sustainable
Find your path to break-even
RunwayCal projects when revenue will exceed expenses on your current trajectory — and shows how to get there faster with scenario modeling.
