Formula & Theory — Consulting Fee Calculator
The core formula or rule used by the Consulting Fee Calculator is shown first, so the explanation that follows can stay tied to the actual calculation:
Base Fee = Rate × Hours/Days (or fixed project fee)
Discounted Fee = Base Fee × (1 − Discount%)
Subtotal = Discounted Fee + Fixed Fee + Rush Fee
Tax Amount = Subtotal × Tax Rate%
Total = Subtotal + Tax AmountTransparent fee calculations help build client trust and reduce negotiation friction.
