Hotel year-on-year percentage calculation formula

1. If the operating income of the current period is greater than the operating income to be compared, what percentage has it increased? The calculation is as follows: Year-on-year increase in operating income (%) = (operating income in the current period-operating income in the previous period) ÷ operating income in the previous period × 100%.

2. If the current operating income is less than the operating income to be compared, by what percentage? The calculation method is as follows: year-on-year decrease in operating income (%) = (comparison or previous operating income-current operating income) ÷ comparison operating income × 100%.
