Why can't I bill 40 hours per week as a consultant?

Independent consultants spend 30% to 50% of their time on unbillable activities like proposal writing, client prospecting, accounting, and professional development. A realistic billable target is 20 to 28 hours per week.

How do consulting day rates differ from hourly rates?

Day rates package 8 hours of work with a slight volume discount or premium for exclusive full-day focus, simplifying client invoicing and reducing time-tracking friction.

What taxes and benefits provision should consultants use?

In the United States, consultants typically budget 25% to 35% for self-employment tax, federal/state income taxes, and private health insurance.

When should I charge a monthly retainer instead of hourly?

Retainers are ideal for ongoing advisory roles, fractional leadership, or long-term strategic support where clients value steady availability over specific logged hours.

What is value-based pricing in consulting?

Value-based pricing sets project fees based on the business value or ROI delivered to the client (e.g. generating $500k in new revenue) rather than the raw hours spent.

How often should consultants raise their billing rates?

Consultants should review and increase rates annually or whenever their demand exceeds available billable bandwidth.

Consulting Rate Formula

\text{Target Hourly Rate} = \left( \frac{\text{Gross Income Target}}{\text{Billable Hrs/Wk} \times \text{Weeks Worked/Yr}} \right) \times (1 + \text{Markup})

The formula calculates gross income required (Salary + Overhead + Taxes) and divides by total annual billable hours, adjusted for profit markup.
