What is Weighted ACV?
With Nnamdi Iregbulem, Partner @ Lightspeed
In this episode, Allan and Lauren talk to Nnamdi Iregbulem, Partner at Lightspeed, about Weighted ACV—a critical metric for SaaS companies managing diverse customer portfolios. Nnamdi explains what makes ACV "weighted," how to calculate it, and when your company should start tracking it.
What is Weighted ACV?
Weighted ACV is Annual Contract Value adjusted to reflect the probability or likelihood that a deal will close. Unlike standard ACV, which treats all contracts equally, Weighted ACV accounts for deal stage, customer segment, or risk factors—giving you a more realistic picture of expected revenue.
Why Weighted ACV matters
Most companies track ACV as a simple average: total contract value divided by number of customers. But this ignores a crucial reality: not all deals are equally likely to close, and not all customers have equal strategic value.
Weighted ACV lets you:
Forecast revenue more accurately — by discounting deals based on their probability of closing
Prioritize high-value opportunities — by weighting deals based on strategic fit or customer segment
Make better resource decisions — by understanding which deals or segments deserve the most attention
How to calculate Weighted ACV
The formula is straightforward:
Weighted ACV = (Contract Value × Probability of Close) / Number of Deals
Or, if weighting by segment or strategic value:
Weighted ACV = Sum of (Contract Value × Weight Factor) / Total Number of Deals
The weight factor depends on your business. It might be:
Deal stage — a 50% probability for deals in early stages, 90% for deals in final negotiation
Customer segment — higher weights for enterprise customers, lower for SMBs
Historical close rates — weights based on how often deals in each category actually close
The key is consistency: define your weighting logic upfront and apply it uniformly across all deals.
When to start tracking Weighted ACV
Start tracking Weighted ACV when:
Your sales pipeline is large and diverse — when you have enough deals at different stages to make weighting meaningful
Deal probability varies significantly — when some deals are much more likely to close than others
You need better forecast accuracy — when your leadership team needs realistic revenue projections, not best-case scenarios
You're managing multiple customer segments — when different types of customers have different values or close rates
Early-stage companies with a handful of deals may not need Weighted ACV yet. But as you scale and your pipeline grows, it becomes essential for accurate planning and resource allocation.
Related metrics
Understanding Weighted ACV is easier when you also track:
Annual Contract Value — the baseline metric before weighting
Net Revenue Retention Rate — how much revenue you're keeping and growing from existing customers
Sales cycle length — how long deals take to close, which affects deal probability
