Nobody teaches this in dental school, and most associates learn it a pay stub at a time. The percentage in your contract is the part everyone talks about, and it is the part that matters least. What matters is what the percentage is applied to, what comes off before it, and what happens in a slow month.
1. The basis: a percentage of what?
An associate contract pays a share of one of three things, and they are not close to each other.
- Gross production is the full fee for everything you did, before anyone writes anything off.
- Adjusted production is production after insurance write-offs, the difference between your office fee and what the plan actually allows.
- Collections is money that actually arrived.
On $80,000 of production in a month at 30%, gross production pays about $24,000, adjusted production around $19,900, and collections around $18,900. Same contract number, more than $5,000 apart in one month.
A 28% of production offer can be worth more than a 32% of collections offer. You cannot compare two offers on percentage alone, which is exactly what most associates do.
The full comparison, with the arithmetic.
2. The collection lag
If you are paid on collections, the money for work you do in August does not arrive in August. Roughly two thirds lands in the first month, a quarter the month after, and the remainder the month after that. It varies with your payer mix, but the shape holds.
This has a practical consequence people miss: a single month can never be checked against itself. A great production month followed by a modest pay month is usually timing, not a problem. You need about three months before a comparison means anything.
3. Lab, and the one word that costs $20,000
Most associate contracts split lab costs, commonly 50/50. The contract also decides whether lab comes off the pot before your percentage is applied, or off your side after.
On $60,000 collected with a $5,000 lab bill you cover half of, at 30%: lab before the split pays you $17,250. Lab after the split pays you $15,500. That is $1,750 a month, around $21,000 a year, from one word.
Both versions appear in real contracts. Both are legitimate. Most associates cannot say which one they are on.
How to tell from your own pay stub.
4. The daily guarantee, and whether it is really a guarantee
"We will guarantee you $600 a day" describes two completely different deals. A true guarantee is a floor: a slow month costs the practice. A draw is an advance: a slow month costs you, later, out of a better month.
In a slow first year the difference decides whether you start month four several thousand dollars behind.
Guarantee versus draw, with the numbers.
5. Tiers, if you have them
Tiered contracts pay a higher rate above a threshold. Two versions exist. Either each band is paid on its own dollars, like tax brackets, or crossing the threshold re-rates the entire month. On 30% up to $50,000 and 32% above, with $70,000 collected, that is $21,400 against $22,400.
Which one your contract describes.
What all of it adds up to
Put the five together and you get the only number that actually describes your deal: your effective percentage, meaning what you were paid divided by what you produced. A 32% contract routinely delivers an effective 26%, with nobody behaving badly at any point.
That number is also the only honest way to compare where you are against an offer somewhere else. Working it out needs a year of your own production next to a year of your own pay stubs, which is the part almost nobody has.
