How Total Contract Value is Calculated?
Total Contract Value (TCV) is the sum of a contract's Total Contract Line Values (TCLV). The TCLV for each line is calculated by multiplying the Sales Price by the Number of Terms. Using a custom trigger with a custom field for the TCLV calculation may lead to inaccuracies. This is because other fields, such as Billing Type and Discount, also affect the calculation.
