Consulting Fees Calculator
Determine your recommended consulting hourly rate, day rate, and monthly retainers based on target income.
What is the Consulting Fees Calculator?
Consulting fee calculation models the optimal hourly rate, daily retainer, or fixed project price required to achieve professional annual earnings goals. It aggregates desired net annual compensation, unbillable administrative time, business overhead expenses, healthcare costs, and billable client utilization hours. This allows independent consultants and advisory firms to establish profitable billing rates that fully cover business overhead and statutory tax liabilities.
Setting the right consulting fees is one of the most critical steps for independent advisors, fractional executives, and freelance professionals. Many consultants undercharge because they fail to account for non-billable administrative hours, self-employment taxes, healthcare benefits, and downtime between client engagements.
Our Consulting Fees Calculator uses top-down financial modeling to determine the exact hourly rate, day rate, and monthly retainer needed to achieve your personal income goals while covering business overhead and building a profit buffer.
