Fixed-Cost Break-Even Examples
Co-Working Space
Fixed Costs: $12,000/month
Desk Price: $300/month
Variable Cost per Desk: $50/month
Contribution = 300 − 50 = $250
Break-Even Desks = 12,000 ÷ 250 = 48 desks
Break-Even Desks = 12,000 ÷ 250 = 48 desks
Manufacturing Plant
Fixed Costs: $100,000
Gross Margin %: 25 %
Break-Even Sales $ = 100,000 ÷ 0.25 = $400,000
Mobile App
Fixed Costs: $8,000/month
Subscription Price: $20/month
Hosting/Support: $3/month
Contribution = 20 − 3 = $17
Break-Even Subs = 8,000 ÷ 17 ≈ 471 subscribers
Break-Even Subs = 8,000 ÷ 17 ≈ 471 subscribers
