Formulas & assumptions
- Net revenue = Revenue − Discounts & refunds not already deducted
- Contribution profit = Net revenue − Direct costs − Customer-specific labour & servicing
- Contribution margin = Contribution profit ÷ Net revenue
- Combined servicing + discounts/refunds = Discounts & refunds + Customer-specific labour & servicing (comparison only; not an additional deduction)
- Profit per service hour = Contribution profit ÷ Service hours
- Shared overheads are not allocated.
What to check next
- Review customer-level revenue, discounts, delivery costs, labour and service hours from your records.
- Check whether large customers receive extra discounts, rush orders or longer payment terms.
- Look at how long each customer takes to pay — slow payers also cost cash.
