The case earns $15,620.00 of contribution per completed project-equivalent before the fixed roster and premises costs. Cash break-even is 1.7 project-equivalents per month under the stated financing. Compare that requirement with usable capacity and actual demand before treating the format as viable.
Define the unit before comparing margins
The unit is one average completed remodeling project. Its contribution deducts specified material, subcontract and payment costs, then supports the standing crew and overhead. The calculation deliberately avoids presenting that contribution as net profit. Compare projects by both contribution and the in-house hours they consume.
Contribution and break-even bridge
| Measure | Value |
|---|---|
| Average revenue per completed project-equivalent | $38,000.00 |
| Variable cost per completed project-equivalent | $22,380.00 |
| Contribution per completed project-equivalent | $15,620.00 |
| Mature fixed operating costs / month | $25,035 |
| Scheduled principal + interest / month | $1,454 |
| Operating break-even project-equivalents per month | 1.6 |
| Cash break-even project-equivalents per month | 1.7 |
| Physical/roster capacity project-equivalents per month | 2.5 |
| Mature modeled project-equivalents per month | 2.1 |
Operating break-even equals monthly fixed costs divided by contribution per unit. Cash break-even adds scheduled principal and interest to that numerator. This is a steady-month test; it excludes changes in working capital and does not recover the opening investment.
What limits the number of units you can sell
Crew hours are person-hours. Three people on a site for one hour use three labor-hours. Apply the productive share before dividing by labor required per project, so estimating, travel and administration are not accidentally sold twice. Subcontract capacity and inspection delays remain additional constraints outside that physical crew ceiling.
A bigger backlog is useful only when it can be scheduled and funded. Sequence projects to minimize idle returns to unfinished sites. Track whether an apparent labor overrun came from rework, waiting for another trade, customer changes or a weak estimate; the remedy is different in each case.
| Input | Case assumption |
|---|---|
| Mature project-equivalents / month | 2.1 |
| Revenue per project-equivalent | $38,000 |
| Materials per project | $12,800 |
| Specialist subcontracting per project | $9,200 |
| Available crew labor-hours / week, including working owner | 120.0 |
| Productive share of available hours | 85.0% |
| In-house labor-hours per project | 180.0 |
| Payment processing / sales | 1.0% |
The operating dashboard to keep
| Metric | How to measure it | Why it matters |
|---|---|---|
| Estimated versus actual hours | Time recorded to each project and work phase. | Revise future estimates using the source of variance. |
| Contribution per crew-day | Project contribution divided by productive in-house crew-days. | Compare jobs with different prices and subcontract shares. |
| Unbilled work and receivables | Completed work not yet invoiced, then invoices by age. | Identify cash committed before collection. |
| Approved change orders | Scope, price, authorization and revised finish date. | Keep unapproved variations out of expected profit. |
| Warranty/callback hours | Hours and materials consumed after handover. | Reserve capacity for quality problems rather than overselling the next job. |
Review these measures with the same service scope and period each time. Investigate changes in price, mix, timing and quality before assuming that a higher revenue total represents an improvement.
A job margin is not monthly cash
Map crew occupancy and collections by project. A profitable job can leave materials and subcontractors unpaid while the final customer balance is outstanding.
Contribution and break-even use the stated unit definition. Collect both its numerator and denominator over the same period. Compare the monthly demand scenarios before interpreting a mature-month threshold as an opening-year result.
