Contract Renewal Value at 53% expected renewal probability: a worked example

This worked example runs the contract renewal value numbers for a tougher week than the baseline: 53% expected renewal probability instead of the typical 74%. Estimate service contract renewal value from renewable contracts, average renewal value, renewal probability, and fixed upsell adjustment.

The inputs for this scenario

  • Renewable service contracts: 165 contracts (held at the documented default)
  • Average renewal value: 4,200 $ / contract (held at the documented default)
  • Expected renewal probability: 53 % (the input this scenario stresses; the baseline uses 74)
  • Fixed upsell or discount adjustment: 28,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Probability-weighted renewal value = renewable contracts × average renewal value × expected renewal probability.
  • Contract renewal value works out to 395,290 $ renewal value at these inputs, and this is the headline figure for the scenario.
  • Average renewal value works out to 2,396 $ / contract at these inputs.
  • Probability-weighted renewal value works out to 367,290 $ renewal value at these inputs.
  • Fixed upsell or discount adjustment works out to 28,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected renewal probability sits at 74% and the headline result is 540,820 $ renewal value, this scenario comes in 26.91% below the baseline at 395,290 $ renewal value.
  • Use it when building a service-revenue forecast, setting renewal quotas, or evaluating the revenue impact of a retention or upsell initiative. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
