## Total Contract Value (TCV)

The Total Contract Value (TCV) is the total value of a subscription over the entire initial contract term. The TCV is an important indicator for the value of a subscription and is often used to evaluate subscriptions.

The TCV is calculated by summing the recurring revenue of a subscription over the entire initial contract term. One-time payments and discounts are also taken into account.

Example:

A subscription has a monthly price of 100 EUR and a contract term of 12 months. The TCV is therefore 1,200 EUR.
If the subscription receives a 10% discount on the first 3 months, the TCV is 1,080 EUR.
If a one-time payment of 100 EUR is added within the 1st contract term (e.g., for consulting), the TCV is 1,180 EUR.

If an upgrade to a higher-value subscription is then performed within the 1st contract term, the TCV is adjusted accordingly.

<Info>
  If a subscription contains multiple currencies, the TCV is calculated in the tenant's default currency according to the currently valid ECB exchange rate.
