Most coaching engagements are 3, 6, or 12 months. A typical 3-month engagement at PCC pricing ($300/session, weekly) runs about $3,600. The same cadence at MCC pricing ($750/session) is $9,000.
Executive-coaching engagements with C-suite clients are typically billed monthly retainers — often $5,000–$15,000/month for a senior MCC working with a public-company executive — and include unlimited contact between sessions.
Many coaches offer a free 30-minute intro call. Use it. Fit matters more than credentials when the credentials are comparable.
