Assumptions

  • This is an estimate. Validate with invoice samples from your top facilities vendors.
  • Leakage rate is applied only to in-scope spend.
  • Category breakdown is for transparency and does not change total savings.
  • Payback is implementation cost divided by monthly savings.

How to use

  1. Enter annual facilities services spend and leakage assumptions using conservative inputs.
  2. Adjust the category shares to match how your facilities services spend is allocated.
  3. Generate the memo and validate the estimate with recent invoice samples.
  4. Revisit inputs quarterly as new controls go live.

What results mean

Estimated annual recoverable savings is the leakage gap on in-scope spend after controls are installed.

Estimated monthly recoverable savings is the annual savings divided by 12 for budgeting and payback.

Payback period compares one-time implementation cost to monthly savings when provided.

Common pitfalls

  • Estimating leakage without checking invoices or dispatch logs.
  • Leaving in-scope spend percent static as controls expand.
  • Not tracking recovered value once disputes are resolved.

Definitions

In-scope spend is the portion of facilities services spend covered by scope, schedule, and approval controls.

Leakage rate is the avoidable or recoverable portion of in-scope spend due to weak scope, approvals, or invoice validation.

Leakage gap is the improvement from current to target leakage rate after controls are in place.
