A rate is set once and then it stops being examined. Costs move every year — wages, insurance, fuel, rent, the compliance load — and the rate moves rarely, in smaller increments, and only when somebody asks.
Because the drift is gradual, nothing announces it. There is no month where the statements say the rate stopped covering the cost. What happens instead is that the organization becomes quietly dependent on something else to close the gap: unrestricted giving, a reserve, another program, or the unpaid extra hours of people who care about the work.
The organizations that get a rate reconsidered are not the ones with the strongest case. They are the ones who can show their arithmetic.
Why the usual answer is not enough
Asked what a unit of service costs, most organizations can produce a number quickly. It is almost always the direct cost — the worker's time, the direct supervision, the participant costs — and it is almost always too low to argue with.
It is too low because it leaves out the things that exist only because the service exists. Someone processes the payroll for those staff. Someone maintains the compliance file the contract requires. Someone answers the audit questions, renews the insurance, administers the systems the work runs on. Those costs are real, they scale with the work, and they are invisible in a direct-cost figure.
A contracting officer is not persuaded by a number. They are persuaded by a build they can follow, and a build has layers.
The five layers
Direct service delivery. The time actually spent delivering the unit, at a loaded rate — not salary. Loaded means salary plus employer taxes, benefits, and paid leave, because those are what the person costs you.
Direct support. Supervision, documentation time, travel, and the required activity that is not the visit itself but cannot be skipped. This is the layer most often left out, and it is frequently substantial: in case-carrying work the documentation and travel around a contact can rival the contact.
Program overhead. Program management, quality assurance, training specific to the service, program-specific insurance and licenses.
Organizational overhead. The share of finance, HR, IT, compliance, executive time, occupancy and audit that the program consumes — allocated on a written basis you can defend, not a percentage you chose because it seemed fair.
Non-productive time. The layer that turns a plausible number into a real one. A full-time worker is not available for delivery for every paid hour. Leave, training, supervision, meetings, and administration all consume paid time, and the cost of the productive hours has to carry the paid hours that are not productive.
The fifth layer is where most estimates break. If you divide annual cost by paid hours rather than by available hours, every downstream figure is understated, and the understatement is not small.
What to do with the gap
Once you have a real cost per unit and the rate you are paid, the gap is arithmetic and so is its annual consequence: gap per unit, multiplied by units delivered.
That figure is the whole conversation. Not "the rate is too low" — a statement every provider makes and no contracting officer can act on — but "delivering this service at this rate costs us this much a year, here is the build, and here is the basis for every allocated line."
Three things make that credible rather than adversarial:
Show the method, not just the answer. A one-page build that someone can follow and disagree with beats a total they have to trust.
Be honest about what is a choice. Some of your cost reflects a standard you have chosen to hold above the requirement. Say so. A cost you can defend as a deliberate quality decision is stronger than one presented as unavoidable and then questioned.
Bring it before you are desperate. A build presented during a planning cycle is a conversation. The same build presented six weeks before you withdraw from a contract is a threat, and it will be heard as one.
Where numbers appear in any worked example — including in our own materials — treat them as illustrations of shape rather than benchmarks. Your cost structure is yours, and a figure borrowed from someone else's model is the fastest way to lose the argument.
What to do this month
Pick your largest contracted service and build the five layers for one unit. Not for the whole program — one unit, one page.
Then compute two numbers: the gap per unit, and the gap multiplied by last year's volume. If the second number is material, you have found something your board should see at its next meeting, and you have found it with arithmetic rather than a feeling.
