An estimated 60 to 70 percent of employed attending physicians are paid, at least in part, on productivity — and a remarkable share of them cannot state their own conversion factor from memory, have never seen the formula modeled at their actual production level, and rely entirely on the employer's annual statement to learn what they earned. That combination is expensive. A Family Medicine physician producing at the median who is paid $7 per wRVU below the median conversion factor leaves roughly $33,000 on the table every year — $330,000 over a decade, before raises compound on the lower base.
This article explains the machinery: what a wRVU is, how base-plus-threshold-plus-conversion-factor formulas actually compute your pay, where the traps are, and how to benchmark your own contract against MGMA data in about ten minutes.
What a wRVU is, and why employers pay on it
Every billable physician service maps to a CPT code, and Medicare assigns each code a number of relative value units (RVUs) through the Physician Fee Schedule. Total RVUs have three components: physician work (wRVU), practice expense, and malpractice expense. The work RVU isolates the physician's own labor — time, skill, intensity — which is why employment contracts use it: it measures what you did, independent of the practice's overhead or what insurers actually paid.
Concrete anchors: a level-3 established patient office visit (99213) is 1.3 wRVUs; a level-4 (99214) is 1.92; a level-5 (99215) is 2.8. A physician seeing 20 patients a day, mostly 99213s and 99214s, generates roughly 30 to 35 wRVUs a day — which is how a full-time outpatient Family Medicine physician lands near the national median of about 4,756 wRVUs a year.
Two properties make wRVUs the dominant productivity currency:
- Payer-blind. A 99214 is 1.92 wRVUs whether the patient has commercial insurance, Medicare, Medicaid, or nothing. Collections-based compensation makes your income depend on payer mix and the billing department; wRVU-based compensation does not.
- Standardized. Benchmarks exist. MGMA and other surveys publish production and compensation percentiles by specialty, which means you can compare your contract to the market with actual numbers.
The values are not static — CMS revalues codes periodically, and the 2021 revaluation of outpatient E/M codes notably increased wRVU credit for office visits. This is why your contract's definition section matters: a contract pegged to an old CMS year can pay you on smaller wRVU values than your work currently carries. Confirm your contract uses the current-year fee schedule values, or understand exactly which year it freezes.
The standard formula: base, threshold, conversion factor
The most common employed-physician structure has three parts:
- Base salary — guaranteed, paid regardless of production.
- Threshold — the annual wRVU level you must exceed before productivity pay begins. Usually set as base ÷ conversion factor, so the bonus turns on once you have "earned out" your base.
- Conversion factor (CF) — dollars paid per wRVU above the threshold.
The formula: total comp = base + (wRVUs above threshold × CF).
Example calculation
Worked example — explicit assumptions: Family Medicine, base salary $240,000, conversion factor $50/wRVU, threshold = $240,000 ÷ $50 = 4,800 wRVUs.
- Produce 4,500 wRVUs → below threshold → total comp $240,000. Effective rate: $53.33/wRVU.
- Produce 4,800 wRVUs → exactly threshold → $240,000. Effective rate: $50/wRVU.
- Produce 5,400 wRVUs → 600 above threshold → $240,000 + (600 × $50) = $270,000. Effective rate: $50/wRVU.
- Produce 5,916 wRVUs (MGMA 75th percentile) → 1,116 above threshold → $240,000 + $55,800 = $295,800.
Note the marginal structure: every wRVU below 4,800 pays you $0 at the margin; every wRVU above pays exactly $50. The threshold placement is therefore worth as much as the conversion factor. The same $240,000 base with a 4,400 threshold pays $20,000 more at 5,400 wRVUs of production.
Variants you will encounter:
- Pure production: comp = wRVUs × CF from dollar one, often with a temporary guarantee for new physicians. Simple, fully exposed to volume swings, and the conversion factor is everything.
- Tiered conversion factors: e.g., $48/wRVU up to 5,000, $54 from 5,000 to 6,000, $58 above. Make sure tiers are marginal (each rate applies only to the wRVUs in its band) and model your expected production against the actual tiers — a high top-tier rate you will never reach is decoration, not compensation.
- Quality holdbacks: a percentage of comp (commonly 5–10%) contingent on quality metrics. Read which metrics, who measures them, and what share of physicians historically earn the full payout.
Part-time and mid-year physicians: confirm the threshold prorates. A 0.8 FTE physician measured against a full-time threshold is mathematically locked out of productivity pay, and a September start against an unprorated annual threshold donates a quarter of the year. The same applies to extended leave — FMLA, parental leave, deployment. Reasonable contracts prorate the threshold by FTE and months worked; silent contracts resolve the question in the drafter's favor.
And the traps, all of which live in the definitions section rather than the formula: whether the threshold prorates for FMLA, ramp-up, or mid-year starts; whether accrued bonus is forfeited if you depart before the payout date (negotiate a pro-rated true-up); and whether your wRVU count credits work you supervise or perform on call.
The benchmarks: what the market actually pays
MGMA's 2026 data for Family Medicine — the reference specialty throughout this article — looks like this:
| Metric | 25th %ile | Median | 75th %ile | 90th %ile |
|---|---|---|---|---|
| Annual wRVUs | 3,595 | 4,756 | 5,916 | 7,085 |
| Conversion factor ($/wRVU) | $47 | $55 | $61 | — |
| Total compensation (median) | — | $231,000 | — | — |
Three ways to use this table on your own contract:
1. Benchmark your conversion factor. If your contract pays $48/wRVU, you are near the 25th percentile of conversion factors. That is a fact you can say out loud in a negotiation, which is more useful than a feeling that the offer seems low.
2. Benchmark your production. If you produced 5,200 wRVUs last year, you are between the median and 75th percentile of Family Medicine production. Production percentile is your leverage: a physician producing at the 75th percentile while being paid a 25th-percentile conversion factor is the textbook underpaid physician.
3. Sanity-check total comp. Median production (4,756) times median conversion (a $55 blended rate) is roughly $262,000 — and median total comp is $231,000. The difference reflects how thresholds, bases, and formula structures spread actual pay; the lesson is that you cannot evaluate a CF or a base in isolation. Model the whole formula at your production level.
Where do these numbers come from? MGMA's annual physician compensation survey is the de facto standard in employment contracts and fair-market-value reviews — many contracts reference it by name as the benchmark for setting conversion factors. Employers buy the full dataset; physicians can benchmark through summary data, specialty societies, or platform tools that license it. Whatever source you use, note the survey year, and use the same year for production and pay comparisons.
One discipline note: benchmarks are specialty-specific. Family Medicine numbers tell a cardiologist nothing. Use your own specialty's MGMA table, and use the same survey year for production and conversion when you compare.
The underpayment math — and its honest assumptions
Here is the calculation that turns a vague suspicion into a number:
annual gap = (median conversion factor − your conversion factor) × your annual wRVUs
Example calculation
Worked example — explicit assumptions: you are a Family Medicine physician; your contract pays $48/wRVU; the MGMA 2026 FM median conversion factor is $55; you produced 4,756 wRVUs last year (exactly the median, to keep it clean).
gap = ($55 − $48) × 4,756 = $33,292 per year.
Stated assumptions, so the number is honest: (1) the median CF is the right comparator for your market and setting — academic, rural, and hospital-employed rates differ, and a below-median CF can be partially offset by a lower threshold or richer benefits, which is why you model the whole formula; (2) your production estimate is annualized correctly (YTD wRVUs ÷ months elapsed × 12); (3) you are comparing within your specialty and survey year. The gap is a negotiation starting point grounded in market data — not money contractually owed to you.
Run your own version with your real CF and production. If the gap is positive, that is the number you bring to a renegotiation, a renewal, or a competing-offer conversation. If it is negative — your rate is above median — that is not a problem to fix; it is an asset to protect in the next contract cycle, and worth knowing before an employer proposes "aligning compensation with market."
Why do gaps like this persist among people as analytical as physicians? Because the data is asymmetric. The employer signs hundreds of these contracts a year and subscribes to the surveys; the physician signs three or four in a career and is handed one number at a time. Closing the information gap is most of the work.
Tracking: the part physicians skip
The formula only pays correctly if the wRVU count is correct, and the count is generated by a chain you do not control: your documentation → coding → the billing system → the compensation report. Errors at every link are common — under-coded visits (a documented 99214 billed as a 99213 quietly donates 0.62 wRVUs per occurrence), procedures that never post, supervision credit that is not applied, and end-of-year reports that do not reconcile with monthly ones.
Supervision and split work deserve a check of their own. If you supervise residents or advanced practice clinicians, your contract decides whose wRVU column that work lands in — billing rules for shared visits have shifted in recent years, and compensation plans have not always kept up. The same goes for work split across sites: make sure cross-site production posts to your total rather than vanishing between cost centers.
The fix is unglamorous: track your own monthly wRVUs and reconcile against the employer's reports. Practically, that means knowing the wRVU values of your 10 to 15 most common codes, pulling your monthly production report (you are entitled to it — ask), and projecting your annual pace: YTD wRVUs ÷ months elapsed × 12. The pace number matters twice — once to catch counting errors early, and once because a physician at 85% of threshold in October still has time to act on it, whereas a physician who learns in February that they missed threshold by 90 wRVUs has just made an interest-free donation.
Key insight
Coding accuracy is compensation. For a physician on a $50 conversion factor, the difference between coding a visit correctly as 99214 versus under-coding it as 99213 is 0.62 wRVUs — $31 — per visit. Habitually under-code three visits a day across 46 working weeks and the donation is roughly $21,000 a year, above threshold. The single highest-yield "negotiation" most RVU-paid physicians can do is with their own documentation.
Common questions
What is a good conversion factor?
There is no universal number — only your specialty's distribution. For Family Medicine in MGMA 2026 data: $47 is 25th percentile, $55 median, $61 75th percentile. A "good" CF also depends on the rest of the formula: a $52 CF with a low threshold and full benefits can outpay a $57 CF with a high threshold and a quality holdback. Model total comp at your realistic production; rank offers by that.
How many wRVUs does a typical full-time physician produce?
Specialty-dependent. Family Medicine: roughly 3,595 at the 25th percentile, 4,756 at the median, 5,916 at the 75th, 7,085 at the 90th (MGMA 2026). Procedural specialties run much higher. Your own trailing-12-month number is the one that matters, and it is worth knowing at all times to within a percent or two.
Are wRVUs affected by what insurance the patient has?
No — that is the point. wRVUs measure the work component of the service; a 99214 carries 1.92 wRVUs regardless of payer or whether the bill is ever collected. (Collections-based or "net revenue" formulas, by contrast, do expose you to payer mix — one reason to prefer wRVU-based terms as an employed physician.)
Can I negotiate the conversion factor at an existing job?
Yes, and renewal is the natural moment. The strongest position combines your production percentile (from your tracked numbers), the market CF (from MGMA data for your specialty), and the gap math above. Employers respond to specific, sourced numbers — "I am producing at the 75th percentile and paid a 25th-percentile rate; the gap is $33,000" — far better than to general dissatisfaction. If the CF won't move, threshold, base, quality-holdback structure, and a true-up clause are alternative levers on the same dollars.
What happens to my wRVU bonus if I leave mid-year?
Whatever the contract says — and the employer-drafted default is often forfeiture of accrued, unpaid bonus. Negotiate a pro-rated payout for production through your last day, before you sign. If you are already bound by a forfeiture clause, factor the accrued bonus into the timing of any departure.
Where do I find my wRVU data?
Your employer's monthly production report (ask administration or your medical director if you have never seen one), the practice's billing system, or your compensation statements. You are entitled to ask for — and should expect to receive — the data your pay is computed from, though contracts and reporting systems vary. If reports are slow or opaque, track independently from your own schedule and code list — it is less precise but catches large discrepancies, which are the expensive kind.
What to do next
- Write down your three numbers: base, threshold, conversion factor. If you cannot find all three in your contract, that is finding number one.
- Pull your trailing-12-month wRVU production and compute your pace: YTD ÷ months × 12.
- Benchmark both against your specialty's MGMA percentiles — production percentile and CF percentile.
- Run the gap math: (median CF − your CF) × annual wRVUs, with the assumptions stated above.
- Reconcile monthly. Compare your own count to the employer's report; question discrepancies in writing.
- Audit your coding for your most common visit types — under-coding is self-inflicted underpayment.
- Calendar your renewal date and bring the production data, the benchmark, and the gap number to that conversation.
If you are an Attending Financial member, the wRVU tracker does steps 2 through 5 continuously — it tracks your monthly entries, projects your annual pace against your contract threshold, benchmarks you against MGMA 2026 percentiles for your specialty, and generates a negotiation-ready report with the gap math already done.
