Billing well is not the same as profiting well. Between revenue and what ends up in your pocket there are taxes, materials, staff, rent and everything else. The calculator organizes those layers and gives you the month's net profit and margin.
Your data stays in your browser. The starting values are a hypothetical example.
What does each field mean?
| Field | What to enter |
|---|---|
| Revenue for the month | What the clinic billed in the month. |
| Variable costs | Materials, commissions and fees that grow with volume. |
| Fixed costs | Rent, staff, utilities, accountant, software, loan payments and, if you like, the pró-labore (owner's draw). |
| Taxes and fees on revenue | Percentage of revenue. |
How is it calculated?
- Taxes = revenue × percentage.
- Contribution margin = revenue minus taxes minus variable costs.
- Net profit = contribution margin minus fixed costs.
- Net margin = profit ÷ revenue.
Worked hypothetical example
Hypothetical example: revenue of R$ 50,000.00, variable costs of R$ 14,000.00, fixed costs of R$ 16,000.00 and 12% in taxes.
| Step | Calculation | Result |
|---|---|---|
| Taxes | 50,000 × 12% | R$ 6,000.00 |
| Contribution margin | 50,000 minus 6,000 minus 14,000 | R$ 30,000.00 |
| Net profit | 30,000 minus 16,000 | R$ 14,000.00 |
| Net margin | 14,000 ÷ 50,000 | 28% |
| Over 12 months, if repeated | 14,000 × 12 | R$ 168,000.00 |
Are revenue and cash the same thing?
No. Revenue is what you sold in the month; cash is what actually came in. Card installments, prepayments and procedures sold in one month and performed in another pull the two apart. For monthly profit, pick one basis (accrual or cash) and keep it every month, otherwise the comparison loses its meaning. Your accountant can advise which basis fits your tax regime best.
How do I use the result?
If net margin falls even with stable revenue, look for the cost that grew. Compare the result with the break-even point, which shows how many procedures pay the costs, and with the revenue needed for your pró-labore. To understand the weight of taxes, the Simples Nacional vs. individual tax simulator.
Frequently asked questions
What is the difference between revenue and net profit?
Revenue is everything that comes in. Net profit is what is left after paying taxes, variable costs and fixed costs.
Does pró-labore count as a fixed cost?
If you want to see profit after your own withdrawal, yes. Without it, profit includes your pay.
What is a good net margin?
It depends on the size, the tax regime and the model of the clinic. Compare against your own history, month by month.
