What is ACV?
ACV — Annual Contract Value — is the average annualized value of a single customer contract. Here's exactly what it means, how it's calculated, and why it matters if you work in customer success.
What does ACV mean?
ACV stands for Annual Contract Value. It's the average value of a single customer contract, normalized to a 12-month period — a way of expressing "how much is this deal worth per year," regardless of the contract's total length.
ACV is most often used to describe deal size — in sales pipelines, forecasting, and account management — and is a common way to compare contracts of different lengths on an apples-to-apples basis.
Simple definition: ACV = Total Contract Value ÷ Contract Length (in years)
ACV is closely related to ARR, and the two terms are sometimes used interchangeably — but they're not always identical. See the ACV vs. other metrics section below, or our dedicated ACV vs ARR comparison, for the distinction.
How is ACV calculated?
The formula is straightforward:
Example
If a customer signs a 3-year contract worth $90,000 total, the ACV is $30,000 ($90,000 ÷ 3). If instead they sign a 1-year contract worth $30,000, the ACV is also $30,000 — even though the total contract value (TCV) is very different.
| Contract | Total value (TCV) | Length | ACV |
|---|---|---|---|
| 3-year deal | $90,000 | 3 years | $30,000 |
| 1-year deal | $30,000 | 1 year | $30,000 |
| 2-year deal | $50,000 | 2 years | $25,000 |
Does ACV include one-time fees?
It depends on the company. Some organizations define ACV strictly around recurring subscription value (in which case it behaves just like ARR at the account level). Others include one-time fees — like implementation or onboarding — averaged into the first year. Always check how your company defines it, since it changes how deal size and quota get measured.
Why ACV matters for customer success managers
ACV shows up in a few places that directly affect a CSM's day-to-day work:
Account segmentation
Just like ARR, ACV is commonly used to bucket accounts into segments — SMB, mid-market, enterprise — which determines how many accounts a CSM owns and how "high-touch" the relationship needs to be.
Renewal and expansion targets
A CSM's renewal or expansion quota is often expressed as a percentage of the ACV they're responsible for retaining or growing — e.g., "maintain 95%+ net revenue retention across your book" where the book is measured in ACV.
Deal size context in sales handoffs
When a deal transitions from sales to CS, ACV is usually the number that travels with it — it tells the incoming CSM roughly how much this account is worth per year and how much time/attention it likely warrants.
Worth knowing: Because our salary database tracks average annual recurring revenue per client rather than a distinct "ACV" field, we don't have ACV-specific compensation data on this page yet — but the same book-of-business dynamics apply. See real CSM pay by book size on our What is ARR? page.
ACV vs. other contract metrics
ACV vs. ARR
ARR (Annual Recurring Revenue) strictly measures recurring subscription revenue, annualized. ACV is the average annualized value of a contract and, depending on definition, may include non-recurring fees that ARR excludes. For a simple recurring-only annual subscription, ACV and ARR are usually the same number. See our full ACV vs ARR comparison.
ACV vs. TCV
TCV (Total Contract Value) is the full value of a contract across its entire length — not annualized. A 3-year, $90,000 contract has a TCV of $90,000 but an ACV of $30,000. TCV tells you the size of the whole deal; ACV tells you the size of one year of it.
ACV vs. MRR
MRR (Monthly Recurring Revenue) is a monthly figure rather than an annual one. ACV ÷ 12 roughly approximates the monthly value of a contract, assuming it's purely recurring revenue.
