Payroll Variance Analysis Between Periods
Spot unusual changes before paying.
The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.
Compare two payroll runs. Totals by employee code for the previous and current period: [PAYROLL_COMPARISON]. Known changes this period: [KNOWN_CHANGES]. Calculate the change for each code in amount and percentage and the change in total. Flag changes beyond [THRESHOLD] percent and those that are not explained by known changes. List possible innocent explanations and the evidence to check. Return a table, the arithmetic for the total, and questions for the payroll preparer. Do not draw conclusions about individuals; use codes only. Add a worked variance example with codes. Employee code 07: previous 2,400, current 2,640, change 240 or 10 percent; known change: pay rise of 10 percent, so explained. Code 12: previous 1,800, current 2,350, change 550 or 30.6 percent; no known change; check overtime. Code 15: previous 2,100, current 0, change minus 2,100 or minus 100 percent; leaver? Total previous 6,300, current 4,990, change minus 1,310, which is minus 20.8 percent. Show how each figure is calculated. Add a rule that large unexplained variances are resolved before payment is released.

Invented codes. Code 07: previous 2,400, current 2,640, change 240 = 10 percent; explained by a pay rise. Code 12: previous 1,800, current 2,350, change 550 = 30.6 percent; no known change; check overtime. Code 15: previous 2,100, current 0, change minus 2,100 = minus 100 percent; leaver? confirm. Totals: previous 6,300; current 4,990; change minus 1,310 = minus 20.8 percent. Resolve codes 12 and 15 before payment. Use codes only. Questions for the preparer: is code 15 a confirmed leaver, and was a final payment due? What overtime explains code 12?
