Year-Over-Year (YoY) Growth Calculation
Year-over-year growth calculation compares a financial metric in one period to the same period in the prior year, expressed as a percentage change. The formula subtracts the prior-year value from the current-year value, divides that difference by the prior-year value, and multiplies by 100. Comparing matching periods strips out seasonality so the result reflects real underlying change.
Problem & Application
For seasonal businesses like campgrounds, RV parks, and short-term rentals, month-over-month comparisons are misleading because a strong summer always beats a weak winter. Year-over-year comparison fixes this by holding the season constant, so a July compared to last July reveals whether the business is genuinely growing. Owners use YoY figures on revenue, occupancy, and average daily rate to separate true performance trends from normal seasonal swings.
In Short
Year-over-year growth is the cleanest way for a seasonal operator to measure real progress without seasonal distortion. Build it into your monthly reporting and the trendline tells the truth.
