G.13Guides · Decision brief
What drives the cost of a consulting engagement
Consulting prices look arbitrary from outside because the quoted number compresses six variables into one figure. Decompressed, the number is legible: who does the work, how much is promised, for how long, under what risk, delivered how, and carrying whose overhead. A buyer who understands the variables can negotiate the structure instead of haggling the total.
The distinction
What is actually being compared?
No responsible page can tell you what consulting costs in dollars: the honest market range for the same deliverable spans 10x or more depending on the variables below, and any specific figure published here would be an invented statistic. What can be said rigorously is what moves the number, and in which direction.
The single largest driver is whose hours you are actually buying. A brand-name firm's fee funds a pyramid: partners sell, juniors execute, and the rate covers training, offices, and the bench between projects. An independent senior advisor charges more per hour of their own time and dramatically less per engagement, because every purchased hour is a senior hour and none funds a pyramid. Neither is overpriced; they sell different cost structures.
The six variables, in rough order of weight
Seniority mix: whether senior expertise does the work or supervises it. Scope: the breadth of the question and the depth of proof demanded; a decision memo and a hundred-page evidence base are different products. Duration and intensity: calendar length times attention share. Risk allocation: fixed prices carry a risk premium, because the seller absorbs the unknowns. Delivery model: on-site travel-heavy delivery bills its logistics; remote delivery deletes them. Overhead: brand, offices, sales apparatus, and the leverage model, all of which the fee funds whether or not the engagement uses them.
What this means at the negotiating table
Negotiating the total while holding all six variables fixed only buys resentment or corner-cutting. The productive move is trading variables: narrow the scope to the decision that matters, accept remote delivery, shift risk by structuring phases with exits, or accept a smaller evidence base where your team can supply the data. Each trade lowers cost for a stated reason, which keeps the relationship honest on both sides.
Be suspicious of a price that will not decompose. A seller who cannot say which variable makes their number large is either bundling overhead you should not fund or has not scoped the work well enough to price it, and both are your problem eventually.
Side by side
The cost variables and who controls them.
| What moves it up | How a buyer moves it down | |
|---|---|---|
| Seniority mix | Senior hands-on work throughout | Scope the senior work to judgment; supply your own analysts |
| Scope and proof depth | Broad questions, heavy evidence requirements | Narrow to the live decision; accept proportionate proof |
| Duration and intensity | Long calendars, full-time attention | Phase the work; buy attention where it compounds |
| Risk allocation | Fixed price over genuine unknowns | Phase gates and exits instead of one big fixed bet |
| Delivery and overhead | Travel-heavy delivery, brand overhead | Remote-first delivery; pay for judgment, not lobby marble |
The call
How to use this before signing
- 01
Ask for the decomposition.
Have every bidder attribute their number across seniority, scope, duration, risk, and delivery model. The comparison between proposals becomes legible in one page, and padding has nowhere to hide.
- 02
Trade structure, not just total.
Offer scope narrowing, phasing, or remote delivery in exchange for price. A seller who refuses every structural trade is defending overhead, not quality.
- 03
Price the decision, not the document.
Anchor the budget to what the decision is worth if made well and what it costs if made badly. That number, not a market rate you heard, is what the engagement should be justified against.

Questions
Asked before scoping.
- Why do consultants rarely publish rates?
- Because the honest rate depends on the six variables, and a published number would either overprice small scoped work or underprice heavy work. Praxis handles this by pricing per engagement after scoping, with the structure explained openly rather than a rate card performed.
- Is an independent always cheaper than a firm?
- Per engagement, usually; per senior hour, often not. And where the work genuinely needs a large parallel team, a firm's leverage model is the right buy. The mistake is paying pyramid prices for work one senior advisor and your own team could do better.
