Client Rate-Cut Impact

Why this comes up

A client asking for a lower rate almost always frames it as low-risk: "just a small percentage." The volume increase actually required to offset that cut is never the same small percentage, and it's always larger, because contribution per unit shrinks faster than the headline rate cut suggests. This engine gives you the real number to bring back to the conversation.

How we calculated this

Old Contribution Per Unit = Old Bill Rate - Relevant Cost
New Contribution Per Unit = New Bill Rate - Relevant Cost
Required Volume Multiplier = Old Contribution Per Unit / New Contribution Per Unit
Required New Volume = Old Volume x Required Volume Multiplier

Worked example: $50/hr cut to $47.50/hr (a 5% cut), $35/hr relevant cost, 100 hours current volume.

Old Contribution Per Unit = 50 - 35 = $15
New Contribution Per Unit = 47.50 - 35 = $12.50
Required Volume Multiplier = 15 / 12.50 = 1.2
Required New Volume = 100 x 1.2 = 120 hours (a 20% increase)

What this means

• A 5% rate cut required a 20% volume increase to hold contribution dollars flat in this example, four times the size of the rate cut itself. The lower your relevant cost is relative to the bill rate, the smaller this multiplier is; the closer cost sits to the bill rate, the larger it gets.
• Past a certain discount, contribution per unit goes to zero or negative and no volume increase can ever recover it; that's a hard "no" regardless of how much volume is offered.
• Bring the required volume number into the negotiation directly: ask the client to commit to it, rather than accepting a vaguer "more volume" promise.

Common mistakes

• Assuming the required volume increase is roughly the same percentage as the rate cut; it's always larger, often substantially.
• Accepting a rate cut on a verbal volume promise without confirming the actual number against this calculation.
• Not checking whether the cut pushes contribution per unit to zero or below, where no volume increase would ever work.

Frequently asked questions

What does "not recoverable" mean?

It means the new bill rate no longer covers relevant cost, so contribution per unit is zero or negative. No volume increase, however large, can make up for a per-unit loss.

How is this different from Volume Discount Break-Even?

This engine computes the required volume from a proposed rate cut. Volume Discount Break-Even takes that required number and checks it against a volume the client is actually offering, use them together.

What should I use for "relevant cost"?

Your loaded direct cost for the worker on this assignment, the same figure you'd use to price the rate in the first place.

Limitations

Assumes relevant cost stays flat at the new volume; a large enough increase may hit overtime or capacity constraints this simple model doesn't capture.
