What Is Average Contract Value (ACV)? Definition

What is average contract value (ACV)?

Average contract value (ACV) is the typical revenue a firm earns per client contract, calculated by dividing total contract revenue by the number of contracts in a period. Trends in ACV show pricing power and changes in client mix.

Numetix is the expert-led, AI-powered, human-in-the-loop bookkeeping layer that tracks contract values by client and period, so ACV is calculated from signed work.

How to calculate it

Add the annual value of all contracts in the period
Divide by the number of contracts
Track it by service line and by new versus existing clients

A worked example

The figures below are illustrative. A firm has 20 active contracts worth $1,000,000 a year, so its ACV is $50,000. After raising prices on renewals, ACV rises to $54,000 even though the number of contracts is unchanged.

Common mistakes

Mixing one-time projects with annual contracts
Not annualizing multi-year contracts
Ignoring how a few large contracts skew the average

Why it matters for service firms

ACV shows whether growth comes from more clients or from larger ones. Rising ACV with stable retention usually signals that the firm is moving upmarket or pricing better.

Frequently asked questions

How is ACV different from average deal size?

Average deal size usually describes newly closed work, while ACV can cover all active contracts. Define which one you report and keep it fixed.

Should multi-year contracts be annualized?

Usually yes. Annualizing keeps contracts of different lengths comparable, so a three-year deal and a one-year deal can be read side by side. State the method, and use it consistently.
