Formula
How this calculator works
This formula converts source operating values into flex percentage for quick review.
Flex % = (1 − ((Change in GOP) ÷ (Change in Revenue))) × 100 when revenue decreases
Context
Why this metric matters
Used when revenue declines to show how much profit is protected through cost flexibility. Sign handling must be consistent.
Hotel insight
Industry context
- Used when revenue declines to show how much profit is protected through cost flexibility. Sign handling must be consistent.
- Small changes in denominator rules can move the result, so keep the same reporting basis when comparing periods.
Operational notes
Before you act on the number
- Revenue fell from $720,000 to $680,000 (−$40,000); GOP fell from $180,000 to $168,000 (−$12,000); Flex = (1 − 12,000/40,000) × 100 = 70.0%
- Confirm whether internal-use, complimentary, adjustment, or excluded activity should be included before comparing periods.
- Use this result as an operating guide and review it with the supporting business context.
