Leap years only affect your Adjusted Increase and Adjusted New Wages totals.
These values are strictly based on the number of days between your Scenario's Start Date, Effective Date, and End Date. The extra day in a leap year will add about 0.27% to your Adjusted Increase ( (1/365) * 100 ) = 0.27.
Example
An Employee makes $10,000, has a Midpoint of $15,000, and qualifies for a 10% raise. We’ll use a Start Date of 1/1/2020, an Effective Date of 1/1/2020, and an End Date of 12/31/2020 for both a regular year and a leap year.
Current Wages | CR | Increase | New Wages | Adj. New Wages | Adj. Increase | Proj. CR | |
Regular Year | $10,000 | 66.67% | $1,000.00 (10.00%) | $11,000 | $11,000 | $1,000 (10.00%) | 73.33% |
Leap Year | $10,000 | 66.67% | $1,000.00 (10.00%) | $11,000 | $11,030.14 | $1,030.14 (10.30%) | 73.33% |
Adjusted New Wages and Adjusted Increase must account for how much an employee makes on a daily basis in order to reflect the Start Date, Effective Date, and End Date. In the leap year example above, Adjusted New Wages is calculated based on the employee making $11,000 for 366 days (11000/365) * 366 = $11,030.14.
Even if an employee receives a 0% annual increase, on a leap year their adjusted increase will still be around 0.27%.
