Risk & Scoring
How Cost is scored
Evidenced waste as a proportion of your own billed spend, converted to a penalty, with a floor below which the domain is not rated.
The calculation
- Read 30-day spend from your own billing data.
- Price evidenced waste from resources that are demonstrably idle, using that same billing data.
- Compute waste as a proportion of spend.
- Convert the ratio to a penalty against a starting score of 100, bounded at 0 and 100.
The penalty multiplier is published in the scoring configuration and printed in the pack, so the arithmetic can be reproduced.
Priced from your data
Never a hardcoded rate and never a fixed percentage of spend. Each waste item carries the evidence that produced it, so the figure can be defended line by line.
Minimum population
Below 100 US dollars of observed 30-day spend the domain is not rated. Waste cannot be a meaningful proportion of a spend that small.
Not assessed when
No cost evidence was collected, the evidence contained no billable spend, spend was below the minimum, or waste could not be evidenced because every probe failed.
When probes fail, waste is null and the domain is reported as not assessed rather than treated as zero waste, which would score 100.
Kept out of the exposure range
Cloud cost recovery is reported separately and is excluded from the exposure range, so a recoverable operating cost is never presented alongside a governance exposure as though the two were the same kind of number.
What it is not
Not a cost optimisation review. It does not right-size, model reserved capacity, or analyse architecture for efficiency.
