What is Annual Contract Value (ACV)?

Annual Contract Value (ACV) is the average revenue a single customer contract generates per year. If a customer signs a three-year deal worth $90,000, the ACV is $30,000 — the value spread evenly across each year.

ACV is most useful in B2B and SaaS, where deals are often multi-year. It lets you compare contracts of different lengths on equal footing and understand the typical size of a customer relationship.

ACV vs. TCV

ACV is easy to confuse with Total Contract Value (TCV), the full value of the whole deal. Knowing both gives a complete picture: TCV shows the total commitment, ACV shows the yearly run rate.

• ACV: yearly value of a contract (total value ÷ number of years).
• TCV: the entire value of the contract over its full length.
• ACV helps gauge whether deals justify your sales effort and cost.
• Higher ACV can support a more hands-on, expensive sales motion.

Why ACV matters for validation

ACV shapes what kind of go-to-market you can afford. A high ACV justifies a dedicated sales team and longer cycles; a low ACV demands cheap, self-serve acquisition to stay profitable. Estimating ACV early tells you whether your acquisition costs and sales approach can ever match the size of the deals — a core test of whether a B2B idea is viable.
