The Payroll Ceiling: Why 45% of Revenue Is a Floor, Not a Budget Line, and What Happens When It Hits 50%

Childcare staffing is not like restaurant scheduling. Every state sets legally binding ratios that dictate how many teachers must be in a classroom per enrolled child. Those ratios vary by age group and jurisdiction, but the ranges are narrow:

• Infants (0–12 months): 1 teacher per 3 to 5 children
• Toddlers (12–24 months): 1 teacher per 4 to 6 children
• Preschool (3–5 years): 1 teacher per 8 to 12 children

A fully enrolled Primrose facility with 300+ seats needs 30 to 45 lead and assistant teachers, plus a center director, assistant director, and administrative staff. You cannot cut headcount without cutting enrollment — which cuts revenue dollar-for-dollar. For more on how Operations & Licensing requirements shape the cost structure, see our dedicated overview.

According to the 2025 Franchise Disclosure Document (CY2024 data), the average payroll and taxes across 413 reporting Primrose facilities was $1,260,772 — exactly 44.8% of the $2,814,801 average gross revenue. Primrose School Franchising SPE, LLC reported these figures across a system of 525 franchised locations with 499 active facilities.

That 45% is not a management choice. It is the cost of meeting the legal minimum staffing requirement at prevailing wages. It is a floor, and it has only one structural direction.

The Bureau of Labor Statistics reports that the median annual wage for preschool teachers is $37,120. That figure understates the problem.

The Center for the Study of Child Care Employment (CSCCE) at UC Berkeley has documented for over a decade that early childhood educators earn approximately 23% less than workers in comparable occupations requiring similar education and credentials. This is not a gap that market forces are closing — it is a gap that generates turnover.

Three forces are compounding simultaneously:

Wages are rising, and not fast enough. Childcare worker wages have increased roughly 26% since 2020, driven by pandemic-era retention crises, state minimum wage legislation, and competitive pressure from retail and food service. Yet median pay remains below $20/hour in most markets. The Center for American Progress has documented that the sector continues to struggle with hiring even after these increases.

Turnover is relentless. Annual turnover in childcare hovers near 40%, according to NIEER workforce crisis research. Every departure costs you recruiting, onboarding, and the enrollment disruption of parents who notice their child’s teacher changed again. The replacement cycle is expensive and constant — our recruitment and retention playbook breaks down the full cost and the systems that cut it.

State minimums keep ratcheting. Over 30 states have enacted or scheduled minimum wage increases since 2020. A center employing 35–45 staff members at $14–$18/hour feels every dollar of increase across the entire payroll. A $1/hour minimum wage increase on a 40-person staff costs roughly $83,000 annually before taxes and benefits.

This is not a cyclical labor shortage that resolves when the economy softens. It is a structural repricing of work that has been systematically underpaid for decades. The NAEYC has identified workforce compensation as the single greatest threat to program quality and access. Smart operators plan for it.

The system-average revenue of $2,814,801 produces very different returns depending on where payroll lands. Here is the math, holding all other costs constant at their FDD-reported levels.

Scenario 1: Payroll at 45% (Current System Average)

This is the number in the FDD. It is the average across 413 facilities reporting CY2024 data. For a detailed breakdown of how EBITDAR and EBITDA diverge — and why the rent gap matters — see the EBITDA margin analysis.

Scenario 2: Payroll at 48%

A 3-point payroll increase — $90,332 in additional labor cost — drops EBITDA by roughly $90,000, from $509K to $419K. That is an 18% erosion in operating profit from a payroll shift that could result from a single round of wage adjustments or a tighter labor market in your geography.

Scenario 3: Payroll at 50%

At 50% payroll, EBITDA falls to approximately $362,000 — a $147,000 decline from the base case and a 29% erosion of operating profit. On a total investment that commonly exceeds $5 million, this compresses your cash-on-cash return meaningfully.

The Bottom Quartile Is Where It Gets Dangerous

The system average masks enormous variance. The bottom quartile average revenue is $1,790,885. At that revenue level, the payroll math becomes punishing. For the full quartile-specific revenue scenarios, see our Item 19 analysis.

At $1.79M in revenue and 50% payroll:

• Payroll: $895,443
• Remaining for all other costs, rent, royalties, and profit: $895,442
• After typical non-payroll operating expenses, occupancy, and franchise fees, EBITDA is negligible or negative

A bottom-quartile facility at 50% payroll is not a business generating an acceptable return on a $5M+ investment. It is a business fighting to break even. Understanding the enrollment ramp cash burn timeline is critical for operators who may spend 12–18 months in this zone.

If you are coming to Primrose from another franchise category, your labor cost intuition is probably wrong.

• Fitness franchises (gyms, boutique studios): Labor typically runs 15–25% of revenue. Most of the service is delivered by equipment, not people.
• QSR and fast casual: Labor runs 25–30% of revenue. Scheduling is flexible — you cut hours when traffic drops.
• Childcare: Labor runs 40–50% of revenue. Ratios are set by law, not by management.

The difference is not degree — it is kind. A gym owner who sees a slow Tuesday afternoon sends a trainer home. A Primrose director who has 8 infants in a room and three teachers cannot send one home because the state says the ratio is 1:3 (or 1:4, depending on jurisdiction). The teacher stays whether the room has 8 children or 12.

This means your labor cost is largely fixed relative to capacity, not variable relative to enrollment. Staffing scales with licensed capacity, not daily attendance. Your payroll on a snow day with 60% attendance is nearly the same as your payroll at full enrollment.

Operators who model childcare labor as a variable cost — adjustable through better scheduling or tighter management — are building on a flawed assumption. The data doesn’t support that model.

You cannot legislate your way out of mandated ratios, and you cannot recruit your way out of a sector-wide wage deficit. But you can structure operations to manage the constraint rather than be surprised by it.

Optimize enrollment mix by age group. Infant rooms require the most teachers per child and generate the lowest revenue-per-staff-member. Preschool rooms at 1:10 or 1:12 ratios generate meaningfully more revenue per labor dollar. The enrollment mix across age groups is the single biggest lever you have on the payroll-to-revenue ratio — within the constraint of market demand and licensing.

Maximize capacity utilization relentlessly. A 350-seat facility at 85% enrollment and one at 97% enrollment have nearly identical payroll. The revenue difference is the entire margin. Enrollment optimization — waitlist management, tour conversion, retention programs — is the highest-ROI activity in a childcare operation because the incremental revenue falls almost entirely to the bottom line.

Build wage competitiveness into your year-one budget. If your market’s prevailing preschool teacher wage is $16/hour and you budget $15/hour to hit a target payroll percentage, you will spend the difference — and more — on recruiting and turnover costs. Pay at or above market from day one. The CSCCE research consistently shows that compensation is the primary driver of workforce stability in early childhood education.

Model at 48% from day one. If you underwrite your investment at 45% payroll and wages increase 3 points over your first five years, your returns will disappoint. If you underwrite at 48% and wages hold at 45%, you outperform your model. Conservative underwriting is not pessimism — it is the recognition that every structural force in this labor market is pushing costs up, not down.

Track cost-per-child-per-classroom monthly. Aggregate payroll percentages hide the dynamics. Break staffing costs down by room and age group so you can see where utilization is strong and where you are carrying staff for partially filled rooms. This operational visibility lets you make enrollment and scheduling decisions with precision.

Payroll at 45% of revenue across 413 Primrose facilities is a system average, not a floor. The forces pushing it higher — mandated ratios, a 23% wage gap to comparable occupations, 40% annual turnover, and rising state minimums — are structural and ongoing. The BLS data and NIEER research point in one direction.

At 48% payroll, your EBITDA drops roughly $90,000. At 50%, it drops $147,000 — a 29% erosion from the base case. For bottom-quartile facilities, 50% payroll is existential.

None of this means Primrose is a bad investment. It means the investment requires a precise understanding of the single largest cost line and the forces acting on it. Operators who underwrite conservatively, optimize enrollment mix, and build competitive wages into their models from day one are positioned to earn the returns the system average implies. Those who treat 45% as a fixed input are building a model on a number that is already moving.
