What the result means
If current customers are below break-even, the company needs more customers, higher ARPA, lower variable cost, or lower fixed cost.
Contribution per customer = ARPA − variable cost. Break-even customers = fixed cost ÷ contribution. Break-even MRR = break-even customers × ARPA.
Break-even improves when ARPA rises or variable cost per customer falls.
Example calculation
With $80,000 fixed cost, $120 ARPA, and $25 variable cost, contribution is $95 and break-even requires about 842 customers.
Tips for better results
- Raise ARPA with better packaging.
- Reduce variable support and infrastructure cost.
- Use break-even MRR as a profitability milestone.
