Estimate Preparation Costs
Estimating costs money too. Producing a quality estimate takes skilled people, time, and data — and that cost rises sharply with the estimate class. This lesson is about budgeting that effort sensibly and recognizing that under-resourcing estimating is a false economy that usually costs far more than it saves. Built on AACE 19R-97.
What estimate preparation cost is
It's a neat twist to end the preparation module on: estimating is work, and work costs money, so the act of estimating has its own cost that can — and should — be estimated. The estimate plan (Lessons 16–17) lays out the effort; this lesson is about pricing and budgeting that effort sensibly.
Why budget the estimating effort
- Plan capacity — Knowing what each estimate costs in effort lets an estimating team plan workload and staffing across projects.
- Match effort to value — Spend estimating effort in proportion to the decision's stakes — not too little for a big commitment, not too much for a quick screen.
- Justify the resources — A budgeted prep cost makes the case for the people and time a quality estimate needs — instead of it being treated as "free."
- Charge / recover cost — For estimating done as a service (e.g., by consultants), the prep cost is what's quoted and recovered.
Drivers of estimate preparation cost
How much an estimate costs to prepare depends on several factors — the main ones:
| Driver | Effect on prep cost |
|---|---|
| Estimate class | The biggest driver — Class 1 costs far more effort than Class 5 |
| Project size & complexity | More scope and disciplines = more take-off and coordination |
| Information availability | Poor/late inputs force rework and chasing, raising cost |
| Methodology | Detailed take-off is labour-intensive; parametric is light |
| Tools & data | Good databases and software reduce effort |
| Schedule pressure | Compressed timelines often raise cost (overtime, inefficiency) |
Using it — and closing Module 2B
For any significant estimate, budget its preparation as part of the estimate plan: size the effort to the required class, secure the people and time, and resist the temptation to cut estimating hours to "save money." A well-resourced estimate is cheap insurance against a badly-informed decision.
Nine things to remember
- Estimate preparation cost is the cost of producing an estimate.
- It's a "meta-estimate" — estimate the hours, people, and time to produce the estimate.
- It scales with class — Class 1 costs far more effort than Class 5.
- Budgeting it lets teams plan capacity and match effort to value.
- Under-resourcing estimating is false economy — it risks far costlier wrong decisions.
- Drivers: class, size/complexity, information quality, method, tools, schedule.
- Class is the dominant lever — choosing the right class controls prep cost.
- Budget prep cost in the estimate plan — secure the people and time.
- Module 2B: requirements → plan → prep budget → documented basis.
