COGS calculator
Calculate margin per treatment before product cost surprises you.
Use this calculator to estimate COGS, gross profit, margin, and waste cost for injectables, GLP-1, IV therapy, peptides, retail, or any other product-heavy cash-pay service.
This calculator is directional. It does not include rent, financing, marketing, payment processing, or overhead. Otzaro focuses on the product-level COGS visibility most cash-pay practices miss.

The hidden issue is not the math. It is keeping the math current.
Product costs change by lot, providers use different amounts, and waste happens quietly. Otzaro records this at the point of service so every visit updates the margin picture.
Where it helps
Use the calculator when the answer cannot wait until month-end.
A quick model can expose whether the economics of a treatment make sense. The next step is making sure those economics stay accurate when real patients, real providers, and real product batches move through the practice.
Pricing a new service
Model the treatment price, product used, supplies, and waste allowance before you put the service on the menu.
Checking provider margin
Add provider payout and product usage to see whether a busy service is actually profitable after COGS.
Finding hidden shrinkage
Add a waste allowance to understand how expired stock, partial vials, or unrecorded usage can erode monthly profit.
Calculator vs operating system
The calculator shows the math. Otzaro keeps the math current.
Treatment economics change when product costs change by lot, providers use different amounts, partial inventory gets wasted, or services are discounted. Static math does not catch that. Point-of-service COGS does.

What does COGS mean in a cash-pay practice?
COGS means cost of goods sold: the direct product and supply cost required to deliver a treatment. In a product-heavy practice, this includes injectables, medication, IV ingredients, consumables, and other direct treatment inputs.
Is this calculator a replacement for Otzaro?
No. A calculator is useful for modeling one treatment. Otzaro keeps the numbers current by tying actual product usage, batches, lot costs, provider activity, and visit revenue together at the point of service.
Why include waste or shrinkage?
Cash-pay practices often lose margin through partial vials, expired product, overuse, unrecorded usage, and ordering mistakes. Adding a waste allowance shows how small leakage can become meaningful at monthly volume.
