What Are Variable Costs in a Dental Practice?
Variable Costs are expenses that increase or decrease in direct proportion to production or patient volume.
In a dental practice, this includes:
- Lab fees
- Dental materials and consumables
- Associate pay (if % of revenue)
- Payment processing fees
- Some marketing tied to new patients
The more you produce, the more you incur these costs —
but if left unchecked, they silently erode profit.
Why Variable Costs Matter for Dental Practice Owners
Many dentists think,
“More revenue = more profit.”
But if variable costs scale too fast — or aren’t monitored — profit can plateau or decline despite growth.
Example:
Month | Revenue | Variable Costs | Net Profit |
Jan | £80,000 | £30,000 (37.5%) | £15,000 |
Mar | £100,000 | £45,000 (45%) | £12,000 |
DentPulse flags these shifts — so you stop chasing top-line growth that reduces take-home income.
Common Variable Costs in Dentistry
Category | Examples |
Lab Fees | Crowns, bridges, aligners (Invisalign, Reveal) |
Materials | Composites, gloves, masks, impression kits |
Associate Pay | % split on revenue for self-employed clinicians |
Finance Fees | Patient plan fees (e.g. Denplan admin) |
Software per Case | iTero scan charges, imaging licenses |
Credit Card Fees | 1.5%–3% on patient payments |
Variable costs are not inherently bad — they just need to be measured, optimised, and scaled profitably.

DentPulse Tip™
High revenue hides low margins.
Variable costs expose the truth.
If your associate or lab costs go up when revenue rises — but profit doesn’t — DentPulse will show you why.
