Enter your employee count, company size tier, and the modules you need. The calculator will estimate your ADP monthly cost and compare it with Gusto, Paychex, and OnPay at the same headcount.
For Roll by ADP: $39 + (employees × $5). For ADP RUN Essential: $79 + (employees × $4-8). For Workforce Now: employees × $23-50 PEPM depending on modules. Use our calculator above to model your exact headcount across all plans and see a comparison with Gusto and OnPay.
Some ADP plans include per-payroll-run charges of $5-15 per run in addition to the monthly fee. This is not always disclosed upfront and depends on your specific contract. If you run payroll bi-weekly (26 times/year), an additional $130-390/year in run fees is possible. Always ask ADP sales to confirm whether per-run fees apply to your quote.
