Payroll PEO Services Segment Margin measures PEO Services segment earnings before income taxes as a percentage of reported segment revenue under ADP's presentation.

ADP reported a 13.1% PEO Services segment margin in fiscal 2026, down 110 basis points from fiscal 2025.

Why it matters

The margin shows how worksite employee growth, pricing, benefit costs, service mix, operating expenses, and zero-margin pass-through revenue interact at the segment level.

Investor caution

Because reported PEO revenue includes zero-margin benefits pass-throughs, the segment margin denominator contains substantial revenue that does not carry margin. It is not directly comparable with Employer Services margin or peer PEO margins without adjusting for presentation differences.

Part of the Payroll & HCM Economics

Connect recurring Employer Services economics, PEO worksite and benefits-pass-through economics, and client-funds float earnings to understand payroll and HCM business economics.

How the model fits together
  • Employer Services growth and retention: Employer Services revenue combines recurring payroll and HCM relationships with new business starts, client revenue retention, pricing, pays per control, and other drivers. New business bookings are an earlier sales measure, while organic constant-currency growth and segment margin show later revenue and profitability outcomes.
  • PEO worksite volume and pass-through economics: PEO revenue combines service economics with zero-margin benefits pass-throughs. Revenue excluding pass-throughs isolates the service revenue base, average worksite employees adds the core population driver, and segment margin shows profitability against the issuer's reported revenue denominator.
  • Client-funds balance, yield, and earnings: Average client funds balances multiplied by portfolio yield provide the core economic bridge into interest revenue, while the extended investment strategy net impact includes additional investment and financing effects. Client funds remain restricted by corresponding client obligations rather than functioning as unrestricted corporate cash.
