Average Deal Size Calculator

Calculate your average deal size and annual contract value — and understand what moving upmarket by 10% means for your ARR.

Average Deal Size (also called Average Contract Value or ACV) is total new ARR divided by the number of new deals closed. It's a critical input for sales forecasting, quota setting, and go-to-market strategy. Moving upmarket by even 20% in ACV can double or triple pipeline value without adding a single new opportunity.

The Formula

Average Deal Size = Total New ARR ÷ Number of Deals

In plain English

Divide total new ARR closed by the number of new deals closed in the same period.

Worked Example

$600,000 new ARR ÷ 50 deals = $12,000 ACV. A 20% ACV increase to $14,400 adds $144,000/yr ARR at the same deal count.

Why Average Deal Size Drives Everything in SaaS Sales

ACV determines your entire go-to-market strategy. Under $5K ACV forces PLG or self-serve (human sales doesn't pencil). $5K–$25K enables inside sales with low-touch motions. $25K–$100K supports inside sales + some field. $100K+ enables enterprise AE teams, executive selling, and customer success investment.

Increasing ACV by 20% at the same deal count and win rate increases revenue by 20% — with no additional headcount. This is why "moving upmarket" is such a high-value strategic move for many SaaS companies.

ACV vs TCV vs MRR

ACV (Annual Contract Value) is the annual value of a contract. TCV (Total Contract Value) is the full value over the contract term — a 3-year $36K deal has TCV of $36K and ACV of $12K. MRR is ACV ÷ 12. Use ACV for sales metrics and ARR calculations. Use TCV for cash flow modelling on multi-year deals.

How to Increase Average Deal Size

ICP tightening: target companies with more employees, higher revenue, or more complexity — they pay more. Packaging: bundle features into tiers that nudge customers to higher-priced plans. Expansion at close: sell multi-seat or multi-product at initial close rather than expanding later.

Champion development: higher-level buyers approve larger budgets. If your deals close with managers, find the VP or C-suite who owns the budget for the problem you solve.

Common Mistakes

⚠️

Including expansion revenue in ACV for new deal benchmarking

ACV for new customer analysis should use only first-year new customer value. Including upsell and expansion revenue inflates ACV and makes your new sales motion look stronger than it is. Track new logo ACV separately from expansion ACV.

⚠️

Using blended ACV across dramatically different segments

If you sell to both SMBs ($5K ACV) and enterprises ($150K ACV), a blended $25K ACV average is misleading. Model each segment separately — they have different sales motions, CAC, sales cycle lengths, and resource requirements.

⚠️

Optimising for deal count over deal quality

A 20% increase in ACV is worth more than a 20% increase in deal count if the cost of acquiring larger deals is lower. High-ACV customers often have lower CAC (relative to deal size), better retention, and higher NRR — making them more valuable per dollar of revenue.
