Connect revisions, subcontract work and agreed changes to project contribution. Start with project time logs, licence invoices and retainer scopes. Each example below uses hypothetical values you can replace.
Revision Round Cost
Price the delivery cost of additional review cycles.
Revision cost = rounds × people × hours × hourly cost
Show example inputs and result
| Extra revision rounds | 3 |
|---|---|
| People involved per round | 2 |
| Hours per person per round | 2 |
| Loaded hourly cost | 45 |
Result: 540 .
Include coordination in recorded hours and do not assume extra rounds are contractually billable.
Open revision round costScope Change Quote
Price a separately agreed change in scope.
Extra quote = (hours × hourly cost + materials + fees) / (1 − margin)
Show example inputs and result
| Extra labour hours | 6 |
|---|---|
| Burdened labour cost per hour | 40 |
| Extra materials | 150 |
| Other extra cost | 30 |
| Target margin | 25 % |
Result: 560 .
Unpriced changes consume labour and materials without raising revenue. Record the extra scope and obtain agreement before using a quote.

Check retained margin on work delivered by a subcontractor.
Margin = (quote − subcontract charge − coordination cost) / quote × 100
Show example inputs and result
| Customer quote | 3,000 |
|---|---|
| Subcontract charge | 2,000 |
| Internal coordination cost | 250 |
Result: 25 %.
Include coordination, inspections, customer service, and expected rework when those costs are yours.
Open subcontract quote marginDelivery Backlog
Translate confirmed work into a simple backlog duration.
Backlog weeks = outstanding sales / weekly completion capacity
Show example inputs and result
| Confirmed outstanding sales | 60 |
|---|---|
| Completed sales per week | 12 |
Result: 5 weeks.
No. It is an average workload ratio. Actual completion depends on sequencing, resources, and job duration.
Open delivery backlogError Prevention Break-Even
Find how many costly mistakes a control needs to prevent.
Errors to prevent = ceiling(prevention cost / cost per error)
Show example inputs and result
| Monthly prevention cost | 500 |
|---|---|
| Fully assigned cost per avoidable error | 125 |
Result: 4 errors per month.
Use avoidable cash or capacity costs. Do not count theoretical opportunity revenue as collected revenue.
