What is Average Deal Size?
Average deal size (also called Average Contract Value or ACV) is the mean revenue value of closed deals over a period. It is a fundamental sales metric that influences quota setting, commission structures, team sizing, and go-to-market strategy. Changes in deal size often signal shifts in customer mix, pricing effectiveness, or market positioning.
The Formula
Average Deal Size = Total Revenue from Closed Deals ÷ Number of Closed Deals
Calculate separately for new business vs renewals vs expansions, as these typically have very different average values.
Worked Example
A sales team closes 15 deals in Q1: total new business revenue of $375,000.
- Average Deal Size = $375,000 ÷ 15 = $25,000
- Median deal = $18,000 (middle value when sorted)
- Largest deal = $80,000, Smallest = $5,000
- Excluding the $80K outlier: Average = $22,143
📌 The $25K average is skewed by one large deal. The $22K average (excluding outlier) and $18K median give a more realistic picture of typical deal size for planning purposes.
Why This Matters
Quota and capacity planning
If average deal size is $25K and target is $500K/quarter, each rep needs to close 20 deals (about 7/month). This determines whether your pipeline and rep count are sufficient.
Sales model alignment
Deal size determines your sales model. Below $5K ACV, you need self-serve or inside sales. $5-50K needs inside sales. Above $50K justifies field sales. Misalignment wastes resources.
Growth strategy
Increasing average deal size (through upsells, multi-year contracts, or moving upmarket) is often more efficient than increasing deal volume. A 20% increase in deal size with the same close rate grows revenue 20%.
Common Mistakes
❌ Using mean instead of median
A few large enterprise deals can dramatically skew the mean. If your deals range from $2K to $200K, the median gives a better picture of a "typical" deal than the mean.
❌ Mixing one-time and recurring revenue
A $50K deal with a $40K one-time fee and $10K ARR has very different long-term value than a $50K ARR deal. Track ACV (annual recurring) separately from total deal value.
❌ Not tracking trends over time
Declining average deal size might indicate you're losing larger deals to competitors, moving downmarket, or offering excessive discounts. Trend analysis is more valuable than point-in-time snapshots.
