What Is Contribution Margin in a Dental Practice?
Contribution margin measures how much revenue remains after deducting variable costs — showing what’s left to cover fixed expenses and generate profit.
In dentistry, it answers the question:
“How much does each treatment, associate, or chair actually contribute towards my bottom line once variable costs are stripped out?”
Why Contribution Margin Matters for Dental Practice Owners
Revenue alone can be misleading. Two treatments might both bring in £1,000, but their contribution margins differ drastically:
- Implant case (£1,000 revenue) – Lab costs £400 → Contribution margin £600
- Composite filling (£1,000 revenue) – Lab costs £50 → Contribution margin £950
Without tracking contribution margin:
- Practices may focus on “busy” treatments that look productive but add little profit
- Associates may be paid on gross production that doesn’t reflect profitability
- Growth decisions risk being based on top-line numbers rather than bottom-line impact
Contribution margin highlights which treatments, providers, and resources truly drive profitability.
Contribution Margin Formula
Contribution Margin=Revenue−Variable Costs\text{Contribution Margin} = \text{Revenue} – \text{Variable Costs}Contribution Margin=Revenue−Variable Costs
- Revenue = income from treatment delivered
- Variable Costs = expenses tied directly to delivery (e.g., associate pay, lab fees, materials, clinical waste)
