At the Year 1 mix, this equipment rental subscription needs about $483k in monthly revenue to cover operating fixed costs Here’s the quick math: fixed monthly costs are about $396k, variable expenses are 18%, so contribution margin is 82%, and $396k / 82% = about $483k The model reaches operating break-even in Month 19, with minimum cash of -$347k in that same month Break-even depends on subscription price, active subscribers, maintenance, logistics, insurance, and churn

Break-even chart Revenue Total costs
Which expenses are fixed, and which move with sales in an equipment rental subscription?
Cost classification
Break-even works only if stable costs stay fixed and revenue-linked costs move with sales. In this model, Month 19 breakeven depends on keeping repairs, logistics, platform fees, and step-up staffing out of the wrong bucket.

How does break-even move from lean to base to full scale for this equipment rental subscription?
Scenario table
As the fleet and team scale, fixed costs rise faster than rent, but the contribution margin also improves. That shifts break-even revenue from about $483k/month in Year 1 to about $762k/month in Year 3.
Planning assumptions only; actual results will move with mix, utilization, and service costs.

What pushes this equipment rental subscription past break-even?
Stress test
The plan is tight: a 10% sales miss or a 5-point drop in contribution margin pushes break-even out fast. Higher fixed overhead makes it worse, especially if churn, repairs, delivery runs, or insurance costs rise at the same time.

What should the founder verify before signing the lease, buying the fleet, and hiring ahead of demand?
Founder checklist
Hold the lease, fleet buy, and hiring until Year 1 demand, mix, and service load match the model. The plan only works if early revenue can support the 82.0% contribution margin, the $11.3K monthly fixed load, and the Month 19 break-even path.
1Tier mix60/30/10 mix
Validate that early customers choose DIY, Pro, and Contractor at the model mix before you buy the full fleet.
2Lease load$11.3K/mo
Confirm the business can carry $5,000 rent inside the full fixed cost base before you sign the warehouse lease.
3Margin check82% CM
Check that Year 1 maintenance, logistics, acquisition, and platform fees stay at 18.0% so the contribution margin holds.
4Service ramp4.5 FTE
Prove that repairs, support, and deliveries need the Year 1 team before you expand toward the Year 2 staffing step-up.

Test the 3.0% trial rate and 40.0% trial-to-paid conversion before you spend past the first-year marketing budget.
