How to Calculate the True Cost of a Device Treatment
Short answer: The true cost of a device treatment combines variable costs (tips or cartridges, consumables, provider pay, card fees) with an allocated share of the device's fixed costs (lease, service, insurance) based on expected monthly sessions. Total cost per session tells you whether the price leaves enough contribution and how sensitive profit is to volume.
Key takeaways
- Include consumables, tips and provider pay in variable cost.
- Allocate fixed device costs using realistic monthly sessions.
- Fewer sessions means a higher fixed cost per treatment.
- Review costs when suppliers or volumes change.
Why does device treatment cost vary so much?
Unlike injectables, much of a device's cost is fixed. If the device runs 40 sessions a month, each carries a small share of the lease; at 10 sessions, each carries four times as much. Ignoring this makes low-volume device treatments look more profitable than they are.
Consumables such as tips or cartridges can also be priced per pulse or per use, which changes cost by treatment area.
How do you calculate cost per session?
- Variable cost per session: consumables, tips, provider pay, card fees
- Monthly fixed device costs: lease, service plan, insurance, software
- Expected sessions per month, based on real data
- Fixed cost per session = monthly fixed costs ÷ sessions
- Total cost per session = variable + fixed per session

The costing sheet separates variable and fixed inputs, works through a hypothetical example and lists controls to keep the calculation current.
Resource 044 is organized into these sections:
- Variable cost inputs
- Fixed cost allocation
- Hypothetical example
- Controls
For the calculation, use tab “044 Device treatment cost” in the Aesthetic Intelligence Calculation Workbook. Blue cells are editable inputs.
