Successive Percentage Changes
Calculate the net effect of two successive percentage changes.
Net Change% = A + B + (A × B / 100)
Formula Explanation
Use signed percentages: increases are positive and decreases are negative.
Variables Explained
A = first percentage change; B = second percentage change.
Solved Example
A value increases by 20% and then decreases by 10%. Find the net change.
Net Change = 20 + (-10) + (20 × -10 / 100) = 8% increase.
