Aftermarket Margin Leakage at 50% recoverable leakage share: a worked example

This worked example runs the aftermarket margin leakage numbers for a tougher week than the baseline: 50% recoverable leakage share instead of the typical 70%. Estimate lost aftermarket margin from leaked transactions, margin leakage per transaction, leakage capture share, and fixed recovery cost.

The inputs for this scenario

  • Aftermarket leakage transactions: 310 transactions (held at the documented default)
  • Margin leakage per transaction: 185 $ / transaction (held at the documented default)
  • Recoverable leakage share: 50 % (the input this scenario stresses; the baseline uses 70)
  • Fixed recovery or audit cost: 9,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Recoverable leakage exposure = leakage transactions × margin leakage per transaction × recoverable share.
  • Aftermarket margin leakage works out to 38,175 $ margin leakage at these inputs, and this is the headline figure for the scenario.
  • Margin leakage per transaction works out to 123 $ / transaction at these inputs.
  • Recoverable leakage exposure works out to 28,675 $ margin leakage at these inputs.
  • Fixed recovery or audit cost works out to 9,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where recoverable leakage share sits at 70% and the headline result is 49,645 $ margin leakage, this scenario comes in 23.1% below the baseline at 38,175 $ margin leakage.
  • Use it to scope a margin-recovery or pricing-audit initiative and check whether the recoverable dollars justify the effort. 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.

Results at a glance

  • Aftermarket margin leakage: 38,175 $ margin leakage (headline result)
  • Margin leakage per transaction: 123 $ / transaction
  • Recoverable leakage exposure: 28,675 $ margin leakage
  • Fixed recovery or audit cost: 9,500 $
