Injector Commission Structures: 6 Pay Models With the Math (2026)

Most aesthetic practices pay injectors with one of six structures: hourly or salary, straight commission, base plus commission, "greater of" hourly or commission, tiered commission, or per-unit and per-syringe pay. Two decisions matter more than which model you pick: whether commission is figured on gross or net service revenue, and whether percentage pay for medical services is permitted in your state. In many states it can be treated as fee-splitting, so have counsel or your state board confirm any structure before you offer it.

The six injector pay models at a glance

One schedule, six results

The same invented injector runs through every model: 4 days a week, 9 hours a day, 48 weeks a year (192 days, 1,728 hours). Average service revenue is $3,000 a day ($576,000 a year). Product cost is assumed at 30%, so net service revenue after product is $2,100 a day ($403,200 a year).

1. Hourly. At $45 an hour: 1,728 × $45 = $77,760. That's 13.5% of gross service revenue and 19.3% of net. Predictable for both sides; nothing changes when the book fills.

2. Straight commission: gross vs net. At 25% of net revenue: $100,800. At 25% of gross revenue: $144,000. Same rate, $43,200 apart. The basis is the decision, not the percentage. On a gross basis the practice pays commission on the product it bought.

3. Base plus commission. $30 an hour ($51,840) plus 20% of net revenue above $1,200 a day: ($2,100 − $1,200) × 20% = $180 a day × 192 = $34,560. Total $86,400, exactly $50.00 an hour, and 21.4% of net revenue. The threshold does the work: it should sit near the production level where the base pay is covered.

4. Greater of hourly or commission. Pay the higher of $45 an hour or 25% of net, figured per day or per pay period. On a full day (9 hours, $2,100 net): hourly is $405, commission is $525, so the injector earns $525. On a slow day ($1,200 net): commission is $300, hourly is $405, so the injector earns $405. The injector gets a floor; the practice absorbs the slow days.

5. Tiered: marginal vs retroactive. Monthly tiers of 20% on net production up to $25,000 and 30% above it. In a 16-day month at $2,100 a day ($33,600 net):

• Marginal (higher rate only on the amount above the threshold): $25,000 × 20% + $8,600 × 30% = $7,580.
• Retroactive (higher rate on everything once the threshold is hit): $33,600 × 30% = $10,080.

Retroactive tiers create a cliff. At $24,900 of production the injector earns $4,980; at $25,000 they earn $7,500. That's $2,520 more pay for $100 more production, a strong pull to squeeze in one more appointment or move one into this month. Marginal tiers avoid it. The commission calculator runs flat, tiered marginal and retroactive plans so you can see where the cliff falls in your numbers.

6. Per unit or per syringe. At $1.50 per unit of toxin and $30 per syringe of filler, a day of 150 units and 3 syringes pays $225 + $90 = $315, or $60,480 over 192 days, usually on top of a base. Pay doesn't change when you discount, which suits practices that run promotions or memberships. It also means the practice carries every discount alone.

Is commission legal for nurse injectors?

It depends on the state, and the answer is often "not as a percentage of medical services." Under the corporate practice of medicine doctrine, many states require medical services to be billed by a physician or physician-owned entity, and sharing a percentage of that fee with someone else can be treated as fee-splitting. The American Med Spa Association has written that paying commission to med spa employees for medical treatments is illegal fee-splitting in most states (2017), and its founder wrote that structured bonus plans are generally permissible (2018). Those are industry articles, not statutes, and both are several years old.

Practical takeaways:

• Ask a healthcare attorney to review the plan for your state before you offer it, and again if you open in another state.
• Ask specifically about percentage pay on medical services, per-unit pay, production bonuses, retail product commission and referral rewards. They aren't treated the same way everywhere.
• If percentage pay is off the table, a salary or hourly rate plus a written bonus plan tied to measures you can document is the common alternative.

Commission and overtime

If an injector is a nonexempt employee, commission doesn't replace overtime. Federal rules say commissions are payments for hours worked and must be included in the regular rate used to calculate overtime, whether commission is the employee's only pay or added to a wage. The Department of Labor's regular-rate fact sheet says all compensation for hours worked, services or performance belongs in the regular rate. For nurses specifically, DOL says RNs paid hourly should receive overtime pay; a salaried RN can be exempt only if paid on a salary basis of at least $684 a week. So an RN employee paid only by commission, rather than on a salary basis, should be treated as owed at least minimum wage and overtime. Confirm with your payroll provider; state rules can be stricter.

What goes in the written plan

California requires commission agreements to be in writing, stating how commissions are computed and paid, with a signed copy given to the employee. It's good practice everywhere. Include:

• The basis: gross or net, and exactly what's deducted: product cost, discounts, membership credits, refunds, card fees.
• When revenue counts: at payment, at service, or when a package or membership session is redeemed. Packages sold in March and used in June need a rule.
• Touch-ups and redos: whether a free touch-up earns anything, and who decides.
• Refunds and chargebacks: whether paid commission is recovered, and over what period.
• Payout timing: each pay period or monthly, and how statements show the calculation.
• Departure: what happens to commission on services already performed but not yet paid out.
• Tier period: monthly, quarterly or annual, and whether it resets.
• Changes: how much notice you give before the plan changes.

How to choose a structure

Pressure-test the plan before you sign it

1. Run three months: slow, typical and full. Does pay as a share of net revenue stay in a range you can afford?
2. Find every cliff: any point where $100 more production changes pay by far more than $100.
3. Check overtime: in a 45-hour week, does the plan still pay correctly?
4. Ask the injector to calculate one pay period from the plan document alone. If they can't, rewrite it.
5. Check your reporting: can you produce revenue by provider, net of product cost, every pay period without a spreadsheet? If not, the plan will create disputes.

Where Prospyr fits

Prospyr's analytics show provider sales, provider utilization and revenue by service alongside cost of goods sold, and inventory management tracks injectables down to the unit, tied to the appointment where they were used. That's the data a net-basis or per-unit plan depends on. Payroll runs in your payroll provider.
