Pay your medspa injector a base salary plus a capped commission on units and treatments, not pure commission and not flat salary alone. Pure commission earns your best nurse injector a bigger check somewhere else within about 18 months, and flat salary quietly caps the volume they book; the hybrid split is the only structure that pays them fairly while keeping the book of business attached to your building instead of their phone.
I have built comp plans for aesthetic clinic owners who kept losing the one injector every regular patient asked for by name. The pattern is always the same, and the math is always the same. Below is the side-by-side, the retention math, and the exact split I recommend, with numbers you can plug into your own P&L today. Run your own scenario in the medspa injector comp calculator as you read.
The three ways owners actually pay injectors
1. Flat base salary
You pay a fixed annual number, say est. $85,000 to $110,000 for a full-time experienced RN or NP injector in most US metros. Simple, predictable, and easy to budget.
The problem: an injector on flat salary has zero financial reason to take the 5:30 PM appointment, upsell a second syringe, or rebook a client for 12 weeks out. Your payroll is fixed, but so is their effort ceiling. I have watched salaried injectors settle into a comfortable 22 to 26 clients a week when the room could hold 35. That gap is pure lost revenue you are still paying rent on.
2. Pure commission (per-unit or percent of service)
You pay a percentage of what they produce, commonly 25% to 35% of service revenue, or a flat per-unit rate on tox (est. $2 to $4 per unit over your cost). Feels fair. Feels motivating. Costs you nothing on a slow week.
The problem is structural, and it is the reason I wrote this article. Under pure commission, the injector owns the economics of every relationship. A high performer doing est. $45,000/month in service revenue at 30% is taking home est. $162,000/year. The moment a competitor across town offers 35%, or the injector realizes they can rent a room and keep 100%, your comp plan has trained them to see your clients as their clients. You have no golden handcuffs, no deferred upside, nothing anchoring them. This is the 18-month poach.
3. Base plus capped commission (the hybrid)
A modest guaranteed base, then commission on production above a threshold, with a structure that rewards retention behaviors, not just raw volume. This is what I put in place, and the rest of this article is the how.
The retention math: why pure commission poaches your best nurse
Here is the arithmetic that owners miss until it walks out the door.
Say your top injector produces est. $540,000 in annual service revenue. Under pure commission at 30%, they earn est. $162,000 and you keep est. $378,000 gross before product cost, rent, front desk, and marketing. Feels fine.
Now a competitor offers the identical 30% plus a $15,000 signing bonus. Your injector’s income is literally unchanged by leaving except for the bonus, because pure commission made their pay portable. There is no vesting, no book equity, no reason to stay. Switching costs them nothing and nets them $15,000. They go. You lose est. $540,000 in revenue and every client who books by name, and you spend est. $8,000 to $20,000 and three months recruiting a replacement.
Now model the hybrid. Same injector: base of est. $60,000, plus 22% commission on all service revenue, plus a 3% retention bonus on revenue from clients who rebook within 6 weeks. Their total comes to roughly est. $60,000 + $118,800 + a retention bonus that lands around est. $12,000 to $16,000 = est. $190,000 to $195,000. They earn more than pure commission gave them, but a meaningful slice is tied to behaviors (rebooking, membership sign-ups) that live inside your systems. When a competitor waves 30%, your injector does the math and sees they would take a pay cut to leave, because the retention bonus and base only exist here. That is the handcuff, built out of their own good work.
The counterintuitive part: I pay the hybrid injector more in total than straight commission would, and it still keeps them, because the money is structured to reward staying and growing the book rather than just showing up and injecting.
The split I recommend, by injector tenure
| Tenure | Base | Commission on service rev | Retention/membership bonus | |—|—|—|—| | New (0–12 mo) | est. $70k–$85k | 15% above a $15k/mo threshold | 2% on rebooked clients | | Established (1–3 yr) | est. $55k–$65k | 22% from dollar one | 3% on rebooks + memberships | | Lead injector | est. $50k–$60k | 25% + 1% of junior injector production | 3–4% + quarterly retention bonus |
Two rules I hold to:
- The base never disappears entirely. Even your lead keeps a real base. A pure-commission “eat what you kill” plan is exactly the portable pay that gets poached.
- Part of the upside must be tied to systems the injector does not own. Rebooking rate, membership enrollments, review generation. Those live in your CRM and your brand, so the comp attached to them cannot leave with the person.
Fund the retention bonus with a membership program
The retention bonus only works if rebooking is easy and predictable. This is where a membership program does double duty: it locks in recurring revenue for you and gives the injector a clean, countable metric to earn against. When a client is on a monthly tox-and-skincare membership, the “did they rebook” question answers itself. I walk through the exact structure in the medspa membership program mechanics guide — set that up first, then bolt the retention bonus onto its enrollment numbers.
How to roll this out without a revolt
Changing comp is the single scariest thing an owner does, because injectors hear “change” and assume “pay cut.” Here is the sequence I use.
- Model each injector’s last 12 months under the new plan before you say a word. If the new structure would have paid them less on real numbers, fix the split until it pays your keepers the same or slightly more. The plan must be a raise for the people you want to keep.
- Present it as a floor plus a bigger ceiling, never as a restructure. “Your base is guaranteed, and here is how you earn past what you make now.”
- Grandfather carefully. For a long-tenured injector already on straight commission, layer the retention bonus on top for the first two quarters before adjusting the base percentage. Give them a taste of the extra money first.
- Put the numbers in writing with a simple one-page comp sheet and a worked example at three volume levels.
If you want a second set of eyes on your specific numbers before you present anything, that is exactly what I do on a free consultation — bring your P&L and your injector’s production history and I will help you build a split that keeps them. You can also reach me directly at tel:+919729712388.
The one mistake that undoes all of it
Do not set the commission percentage so high that the base becomes irrelevant. If your injector earns 33% commission and a $50k base, the base is 8% of their income and provides zero retention pull — you have a pure-commission plan wearing a costume. The base and the retention bonus together should be a large enough share of total pay that leaving genuinely costs them money. Aim for base plus bonuses making up at least 30% to 40% of total compensation for the plan to actually hold anyone.
Get that ratio right and you stop training your best nurse injector to build a book they can carry out the door. You start paying them to build one that stays in your building.
FAQ
Should I pay a medspa injector salary or commission?
Neither alone. A flat salary caps their effort and leaves revenue on the table; pure commission makes their pay fully portable and gets them poached within about 18 months. Base plus a capped commission plus a retention bonus pays them fairly and keeps the book of business attached to your systems.
What is a fair commission rate for a nurse injector?
Most US medspas run est. 22% to 30% of service revenue, or est. $2 to $4 per unit of tox over cost. I recommend keeping straight commission toward the lower end (around 22%) and adding a real base plus a 2–4% retention bonus, so total pay is competitive but not fully portable.
Why does pure commission cause injectors to leave?
Because it trains the injector to see the client relationships as theirs, not the clinic’s, and it gives them nothing that only exists if they stay. A competitor matching the rate plus a signing bonus makes leaving free. A base and a retention bonus tied to your CRM and membership program make leaving cost them money.
How much should the base be versus commission?
Base plus retention bonuses should be at least 30% to 40% of total compensation. Below that, the guaranteed portion is too small to anchor anyone and you effectively have a pure-commission plan. Model each injector’s real last-12-months numbers before rolling anything out so the plan is a raise for the people you want to keep.
