Equipment investment return calculator

Before buying equipment, one question settles half the decision: in how many months does it pay for itself? The calculator answers with the real margin of each session, the monthly maintenance and the number of sessions you believe you will sell.
Your data stays in your browser. The starting values are a hypothetical example.
What does each field mean?
| Field | What to enter |
|---|---|
| Equipment investment | Purchase price, shipping, installation and training. |
| Sessions per month | How many new sessions you realistically expect to sell. |
| Price charged per session | The session price for the patient. |
| Cost per session | Tip, disposable, gel and other items per session. |
| Taxes and fees | Percentage of the price. |
| Maintenance and insurance per month | Recurring costs of the equipment. |
How is the calculation done?
- Margin per session = price × (1 minus taxes) minus cost per session.
- Monthly margin = sessions × margin per session minus maintenance.
- Payback = investment ÷ monthly margin, in months.
- Sessions to pay off in 24 months = (investment ÷ 24 + maintenance) ÷ margin per session.
Worked hypothetical example
Hypothetical example: R$ 80,000.00 of investment, 25 sessions per month at R$ 600.00, a cost of R$ 80.00 per session, 12% taxes and R$ 500.00 of maintenance.
| Step | Calculation | Result |
|---|---|---|
| Margin per session | 600 × 0.88 minus 80 | R$ 448.00 |
| Monthly margin | 25 × 448 minus 500 | R$ 10,700.00 |
| Payback | 80,000 ÷ 10,700 | 7.5 months |
| Margin in 12 months | 10,700 × 12 | R$ 128,400.00 |
| Sessions to pay off in 24 months | (3,333.33 + 500) ÷ 448 | 9 |
How do you use the result?
Compare the margin per session with the value of your hour in the clinical hour value, to see whether the session is worth more than your time on another service. To see the clinic's overall break-even after the purchase, use the break-even point. And to estimate the effect of repeat purchases, the patient LTV.
Frequently asked questions
How do you calculate the payback of a piece of equipment?
Divide the amount invested by the monthly margin the equipment generates, after taxes, cost per session and maintenance.
Do the equipment's sessions need to be new?
Yes. If the patient would swap another service for this one, the revenue is not additional and the payback is longer than it looks.
Is buying equipment always a good deal?
Only if the number of realistic sessions pays back the investment in an acceptable time, with training, regulatory approval and the professional's qualification sorted out.
