=IF(A2=0, "N/A", (B2-A2)/ABS(A2))This formula calculates the percentage change in revenue from the previous year to the current year, accounting for zero or negative prior year values.
Step-by-Step Breakdown
- Step 1: Check if the prior year revenue (A2) is zero.
- Step 2: If A2 is zero, return 'N/A' to indicate no growth can be calculated.
- Step 3: If A2 is not zero, calculate the difference between current year revenue (B2) and prior year revenue (A2).
- Step 4: Divide the difference by the absolute value of the prior year revenue (A2) to get the percentage change.
