Return on Investment (ROI) is a key metric that evaluates how well your expenses are justified. In the aesthetics industry, ROI is essential to determine whether your investments are working for you.
How to Calculate ROI?
The formula is straightforward:
ROI = (Net Profit ÷ Total Costs) × 100%
🌟 Net Profit:Your revenue from a treatment minus all associated costs, including equipment, materials, salaries, and other expenses.
🌟 Total Costs:The total investment required to launch and deliver the service.
Example Calculation
Let's calculate the ROI for our most popular facial - Hydrodiamond. I will use the Zemits Verstand HD system for this calculator as an example.
You invested £5,500 in equipment.
1️⃣Investment (Equipment Cost): £5,500
2️⃣Consumables Cost per treatment: £5
3️⃣Staff Salaries and Other Expenses per treatment: £30
4️⃣ Revenue per treatment: £120
5️⃣Number of Treatments: 100

Step 1: Calculate Total Revenue
➡️ Total Revenue =Revenue per treatment × Number of Treatments
➡️ Total Revenue=120×100=£12,000
Step 2: Calculate Total Costs
➡️ Total Costs=(Consumables Cost per treatment + Staff and Other Expenses per treatment) × Number of Treatments + Equipment Investment
➡️ Total Costs=(5+30)×100+5,500=35×100+5,500=£9,000
Step 3: Calculate Net Profit
➡️ ROI=(Investment / Net Profit)×100
➡️ ROI=(5,500 / 3,000)×100≈ 54.55%
This means that after 100 treatments, your profitability reaches 54.55% of your initial investment. Net Profit after 100 treatments: £3,000
Why ROI Matters
ROI helps you evaluate current performance and plan future investments. By accurately calculating ROI, you can determine whether to adjust pricing, optimise costs, or improve marketing to boost profitability.
