What is the difference between TCV and ARR?
TCV is the total value of a single signed contract across its full term, including recurring subscription, one-time services, and implementation. ARR is the annualized recurring subscription value of the entire active book across every customer, with services excluded. TCV is per-contract and total. ARR is book-wide and annualized. The two numbers answer different questions and should never be reported interchangeably.
What is the difference between ACV and ARR?
ACV is TCV divided by the number of years in the contract, giving the average annual value of one deal, including services smoothed across the term. ARR is the annualized recurring subscription value of the entire book, with services excluded. On a deal with meaningful implementation fees, ACV is higher than the ARR contribution from that same deal, because services are in ACV but not in ARR.
How do you calculate TCV?
TCV equals the sum of every committed line item on a signed contract across the full term. For a three-year subscription at a flat annual price, TCV is three times the annual price, plus any implementation, services, training, or committed usage minimums. If the subscription steps up by year, TCV adds each year at its own contracted price. The number is set the day the contract is signed and does not move unless the contract is amended.
How do you calculate ACV?
ACV equals TCV divided by the number of years in the contract term. A three-year deal with a six-unit TCV has a two-unit ACV. Most teams use the simple average across the term. If pricing steps up by year, some policies also report year-one ACV separately for forecast and compensation clarity. ACV is a per-deal number, not a company-wide metric.
Should sales commissions be paid on TCV, ACV, or ARR?
There is no single right answer, but the most common pattern pays on TCV with accelerators tied to multi-year commitment, because the rep closed the full commitment. Some plans pay on year-one ARR to align sales incentives with the metric the board underwrites. The important rule is that whichever number the plan uses, finance reports it the same way, so the plan payouts and the growth reports reconcile without argument.
Why does mixing TCV, ACV, and ARR break the forecast?
If pipeline is logged in TCV but the target is set in ARR, every multi-year deal in pipeline overstates coverage. A three-year deal looks like three units of target when it contributes only one unit of new ARR. The forecast reads healthy and the end-of-quarter report lands short. The fix is to carry all three numbers on every opportunity and route each one to the audience that owns it.
Do multi-year contracts count as new ARR for all three years?
No. New ARR counts the annualized recurring value in effect today, once. A three-year deal contributes one unit of new ARR when the deal closes, not three. The remaining two years of commitment live in TCV. If pricing steps up in later years, the step-up is recognized as expansion ARR on the anniversary, not as new ARR up front.
What should a CRM track for contract value and ARR?
A CRM should hold TCV, ACV, and ARR as three separate derived fields on every opportunity, computed from the same contract line items. The deal record should also capture contract term in years, each line item as a typed row, and the recurring versus one-time flag. Services and implementation should be in their own line items so ARR can exclude them while TCV and ACV include them. One source of truth, three audience-specific rollups.
