Rate Cards and How Engagement Margin Actually Moves
Two engagements at the same fee and the same effort can differ by twenty points of margin. The difference is who did the work.
A rate card is the set of prices a firm charges per grade per unit of time. It looks like a pricing artefact and is really a staffing artefact, because the moment a fee is agreed the margin is no longer determined by the price. It is determined by the mix of people who deliver the work, and that mix is decided weekly by whoever is resourcing.
This is why firms with disciplined pricing still produce inconsistent margin. The rate card was applied correctly at proposal and then a senior manager covered for an unavailable consultant for three weeks, and nobody recalculated anything.
The three rates that matter
Margin lives between charged and cost. Realisation lives between standard and charged. Firms that track only the first two can see that they discounted and cannot see whether the work was profitable. Firms that track all three can answer the only question that matters at engagement level, which is whether this piece of work made money.
- Standard rate: the published price for a grade. What the rate card says.
- Charged rate: what this client actually pays after negotiation, which may be a discount, a blend, or a fixed fee that implies a rate.
- Cost rate: what an hour of that grade actually costs the firm, fully loaded. Salary, employment costs, and an allocation of overhead.
Grade mix, with the arithmetic
Consider a fixed fee of one hundred thousand for a thousand hours of work. Assume, for illustration, that a consultant costs the firm sixty an hour fully loaded and a manager costs one hundred and twenty.
Delivered entirely by consultants, the cost is sixty thousand and the margin is forty per cent. Delivered with three hundred of those hours by a manager instead, the cost is sixty thousand less eighteen thousand plus thirty six thousand, which is seventy eight thousand, and the margin has fallen to twenty two per cent. The fee did not change, the hours did not change, and eighteen points of margin disappeared into a resourcing decision that was probably made in a scheduling conversation on a Monday.
This is the single most useful piece of arithmetic in the business, and it explains why senior-heavy delivery is the most common cause of a well-priced engagement losing money. It is also why the leverage model, meaning the ratio of junior to senior time, is a strategic decision rather than an operational one.
What a rate card should carry beyond the rate
A card that lists only grade and price is missing what an engagement needs to compute anything useful.
- The cost rate per grade, held alongside the charge rate, so margin is computable without a separate exercise in finance.
- An effective date, because rates change annually and an engagement spanning a rate change must know which applied when.
- Currency, for firms operating across borders, held explicitly rather than assumed.
- The client or engagement it applies to, since most firms run a standard card and a set of negotiated ones and the negotiated one always wins.
Where rate cards are misused
The most common misuse is discounting the rate rather than the scope. A client pushing on price is easier to satisfy with ten per cent off the rate than with a conversation about what will not be delivered, and the ten per cent comes straight off margin because the cost is unchanged. Reducing scope preserves the economics; reducing rate does not.
The second is a blended rate agreed for convenience and then delivered with a mix that does not match the blend. A blended rate assumes a leverage model, and if delivery is more senior than the blend assumed, the firm is losing on every hour while its reporting shows the agreed rate being charged correctly.
The third is failing to update cost rates. Salaries rise annually and cost rates frequently do not, so margin reported through the year is systematically flattering, and the correction arrives at year end as a surprise that gets attributed to delivery rather than to arithmetic.
Making it operational rather than theoretical
- Compute margin at engagement level monthly, using actual recorded effort against actual grade cost rather than planned mix.
- Report the variance between planned mix and actual mix, because that variance is the early warning and it is visible weeks before the margin moves.
- Give the person resourcing the engagement visibility of the margin consequence, since they are the one making the decision that determines it.
- Review cost rates at least annually and restate the year to date when they change, so the correction is understood as arithmetic rather than performance.
