You quoted a client $300 for a session, they said yes without blinking, and instead of feeling good you felt a little uneasy. Was that enough? After the supplies, the booking software, and the time it actually took — did you make money, or did you just stay busy?

That nagging feeling has a name, and a number behind it. It's called gross margin — and once you can see it, pricing stops feeling like a guess.

What gross margin actually means

Gross margin is how much of every dollar you bring in is left after the direct costs of delivering your service — the supplies, the materials, the payment processing, anything you only spend because you did that specific job.

Think of it as the strength of each dollar. Two businesses can both bring in $10,000 a month and be in completely different shape — the one keeping 70 cents on the dollar has room to breathe, and the one keeping 25 cents is running hard just to stay in place.

The formula:

(Revenue minus direct costs) ÷ Revenue = Gross margin

So if you charge $300 for a service and the direct costs to deliver it are $90, your gross margin is ($300 − $90) ÷ $300 = 70%. For every dollar that comes in, you keep 70 cents to cover rent, your time, and profit.

What a healthy number looks like

Margins vary by business type, but here's a useful starting guide for service-based work:

• Under 40%: your direct costs are eating too much; revisit pricing or suppliers
• 40 to 60%: workable, but watch for creep in supply costs
• 60 to 80%: a healthy range for most service businesses
• 80% or more: strong, and common when your main input is your own expertise

A high margin doesn't mean you're rich — it means each sale gives you something to work with. A low margin means you have to sell a lot more to reach the same place, which is how people end up busy and broke at the same time.

What to do next

1. Pick your most common service and write down what you charge for it
2. List every direct cost to deliver it once: supplies, processing fees, anything job-specific
3. Do the math: (price minus direct costs) ÷ price = your gross margin
4. If it's under 50%, that's your signal this week: raise the price or trim a cost, then recheck the number
