Consulting clients are buying clarity, speed, and fewer expensive mistakes. That is why experienced consultants can charge $150-$350 per hour even when the actual meeting time looks modest; the real value is the years of pattern recognition behind the recommendation. If your work changes hiring, pricing, operations, or go-to-market decisions, your rate should reflect the size of those decisions.
Utilization is the number most new consultants get wrong. A solo consultant who sells, scopes, travels, prepares decks, and follows up usually lands closer to 50-65% utilization over a year, not 90%, which means your billable hours must carry all the non-client work too. A consultant charging $125 per hour with only 15-18 billable hours most weeks often ends up earning less than expected.
Protect margin with minimum engagement sizes and cleaner packaging. Strategy sessions, diagnostics, and retained advisory work are usually stronger than ad hoc one-hour calls because they reduce context switching and let you plan capacity. Many consultants should have a clear floor such as a half-day minimum, a monthly retainer of $2,000-$5,000, or a paid audit before any custom implementation begins.
