❓ Frequently Asked Questions

"X% of Y" (e.g., 20% of 150 = 30), "X is what % of Y" (e.g., 30 is 20% of 150), and "% change from X to Y" (e.g., 80→96 = +20%).
Use Mode 1: Enter the discount percentage and the original price. Example: 25% of $80 = $20 saved, final price = $60.
Yes — use Mode 3 (percentage change). If the new value is lower than the original, the result will be negative (e.g., 100→80 = -20%).
A percentage point is the absolute difference between two percentages. If a rate goes from 3% to 4%, that's 1 percentage point increase — but a 33.3% relative increase.
