Market Penetration Index (MPI)
The Market Penetration Index (MPI) measures a property's occupancy performance relative to its competitive set. It is calculated by dividing the property's occupancy rate by the average occupancy rate of a defined comp set, then multiplying by 100. An MPI of 100 means the property is capturing its fair share of available demand. An MPI above 100 indicates the property is outperforming its competitive set on occupancy; below 100 signals it is losing share, even if absolute occupancy looks acceptable in isolation.
Problem & Application
An RV park or campground operator may see steady or even growing occupancy year over year and conclude the property is performing well. But if the broader market grew faster during the same period, the property is actually losing competitive ground -- a trend that will eventually manifest as revenue underperformance once market growth normalizes. MPI surfaces that gap early. For operators planning capital improvements or pricing changes, knowing whether the property is gaining or losing share relative to nearby competitors helps prioritize investments with the highest probability of driving market share recovery.
In Short
MPI is a relative performance lens that internal numbers alone cannot provide. Tracking it alongside absolute occupancy gives hospitality operators an early warning system for competitive erosion before it hits the bottom line.
