Average Deal Size
What is the average deal size?
Average deal size is the mean revenue value of closed engagements over a period. If you closed 10 new clients totaling $500,000 in annual contract value, your average deal size is $50,000. This metric helps forecast revenue from your pipeline, set sales targets, and evaluate whether you are attracting your target client profile or drifting toward smaller or larger engagements.

Why average deal size matters
Larger deals typically require more sales effort but yield better unit economics. Smaller deals close faster but may not justify the acquisition cost. Tracking average deal size reveals whether your marketing and sales efforts are attracting the right prospects. A declining average might indicate market positioning issues. An increasing average suggests you are moving upmarket.
Using deal size for planning
Revenue targets divided by average deal size tell you how many deals you need to close. If your target is $1 million and average deal size is $50,000, you need 20 new clients. Work backward to required proposals, meetings, and leads. Changes in average deal size ripple through the entire forecast. Update your planning assumptions when the metric moves materially.
A worked example
The figures below are illustrative. A firm closes eight engagements worth $480,000 in annual contract value, so its average deal size is $60,000. Splitting the deals by service shows that advisory deals average far more than monthly accounting, which guides where to focus sales effort.
Common mistakes
- Mixing one-time projects with annual recurring contracts
- Letting one very large deal skew the average
- Ignoring the median
Frequently asked questions
Should the average or the median be used?
Use both. A few large deals can pull the average up, while the median shows the typical deal. Comparing the two shows how much a few big engagements are affecting the picture.
How is average deal size different from average contract value?
The two are close. Average deal size usually describes newly closed work, while average contract value often covers all contracts in a period. Define which you use and keep it fixed.
