ROI in the HOF Clinic: What It Is and How to Calculate It
Quick facts
- Definition
- Return on Investment: profit obtained relative to the amount invested, usually as a percentage.
- Formula
- ROI = (gain from the investment minus the cost) ÷ cost.
- Different from
- ROAS, which measures revenue over ad spend and ignores costs beyond media.
- Relevance in orofacial harmonization (HOF)
- Helps decide on equipment, renovations, training and marketing by comparing alternatives.
ROI, short for return on investment, measures how much profit an investment produced relative to the amount put in. In an orofacial harmonization (HOF) clinic, the question comes up in decisions such as buying equipment, renovating a room, taking a course, hiring someone or investing in marketing.
What is the formula?
Subtract the cost from the gain and divide the result by the cost. The number is usually shown as a percentage.
| Item | Value (hypothetical example) |
|---|---|
| Investment in equipment | R$ 40,000.00 |
| Profit generated in 12 months from using the equipment | R$ 52,000.00 |
| Net gain (profit minus investment) | R$ 12,000.00 |
| ROI | 12.000 ÷ 40.000 = 0,30, or 30% |
Note: the key word is profit, not revenue. If the number used is revenue, the calculation looks great, but it is not ROI. The example is hypothetical and does not represent a market average.
Which costs are included?
All those the investment generates: purchase or rental, supplies, the clinical hour used, training, maintenance, taxes and, when financed, interest. Forgetting a cost inflates the ROI. The contribution margin of each procedure performed with the new investment is the basis for estimating profit.
Time also matters. An ROI of 30% in six months is very different from the same figure over five years. That is why ROI is often paired with the payback period, which tells you how long it takes for the investment to pay for itself.
How does idle capacity affect the result?
Many clinics calculate the return as if the schedule were always full. In practice, there is idle capacity: available hours that nobody fills. Expensive equipment in a lightly booked schedule takes a long time to pay off. Calculating ROI with a realistic usage estimate, not the ideal schedule, avoids disappointment.
The difference between seeing money come in and recognizing the result for the period also weighs in. Cash and accrual accounting affect when the return appears in the records, and the income statement (DRE) helps show the profit for the period.
ROI and marketing?
For ads, ROAS is the quick measure, and ROI is the complete one. A campaign can have a ROAS of 4 and a negative ROI if the procedure's margin is small. Looking at both avoids decisions based on a single metric. The average ticket enters as a component of the calculation.
Also called: return on investment.
Frequently asked questions
What is the difference between ROI and ROAS?
ROAS divides revenue by ad spend. ROI considers profit after all costs, relative to the amount invested. ROI is more complete and harder to measure.
