Average Contract Value (ACV)
The annualised value of a contract, averaged across a set of deals. The standard unit for comparing new business.
What it normalises
Average contract value is the annualised value of a contract: total contract value divided by its length in years. Its purpose is comparability — it lets a one-year deal and a three-year deal be compared on the same basis, which total contract value does not.
ACV = total contract value ÷ contract term in years. Where contracts include one-off services, those are conventionally excluded, because including them makes ACV move with delivery work rather than with the recurring base.
ACV, TCV and ARR are three different numbers
How to use it
Decide whether services are in or out and document it. Out is the more useful convention because it keeps ACV comparable to recurring revenue.
Report average ACV alongside the distribution. A mean pulled by two large contracts describes none of your deals.
Track new-business ACV separately from blended. New-business ACV is the leading indicator of whether you are moving up-market; blended lags by the length of your contracts.
Compare ACV against CAC rather than TCV against CAC. Payback calculated on total contract value assumes the whole contract is collected and retained, which is the assumption most likely to be wrong.
Check ACV against ARPA. Material divergence means expansion is happening after the initial sale, which is worth knowing and is invisible in either figure alone.
Where it misleads
It assumes even value across the term. Contracts with ramped pricing — cheaper in year one — have an ACV that describes no actual year.
Excluding services understates the revenue from a delivery-heavy contract; including them overstates the recurring base. Neither convention is wrong, but the choice must be consistent.
A rising ACV can reflect longer contracts rather than larger ones if the calculation is done carelessly on TCV without dividing by term.
Averages hide a bimodal customer base. Many businesses have a small-deal motion and an enterprise motion, and the mean sits in a gap where no customers are.

Average Deal Size
The mean value of closed-won opportunities over a period. An input to pipeline velocity and capacity planning.
Bookings
The total value of contracts signed in a period, regardless of when revenue is recognised or cash collected.
Total Contract Value (TCV)
The full value of a contract across its entire term, including non-recurring elements.
COMMON QUESTIONS
- What is average contract value?
- The annualised value of a contract — total contract value divided by its length in years. It exists to make deals of different lengths comparable, which total contract value cannot do. Services revenue is conventionally excluded so that ACV stays comparable to recurring revenue.
- What is the difference between ACV and TCV?
- TCV is the whole value of the contract across its full term; ACV is that figure annualised. A three-year $300k contract is $300k TCV and $100k ACV. Both are legitimate, but they answer different questions and reporting whichever is larger without saying which is the most common presentational error in SaaS reporting.
- Is ACV the same as ARR?
- Closely related but not identical. ACV describes the annualised value of an individual contract; ARR describes the annualised recurring revenue of the whole book at a point in time. A contract's ACV contributes to ARR, but ARR also reflects expansion, contraction and churn across the base, which a contract-level figure cannot.
- Should ACV include professional services?
- Usually not. Including one-off implementation and services revenue makes ACV move with delivery work rather than with the recurring base, which defeats the purpose of having a normalised figure. Whichever convention you choose, document it — the inconsistency causes more confusion than either choice does on its own.
