Frequently Asked Questions
What is the difference between percentage and percentage points?
Percentage is a relative change. Percentage points are an absolute difference between two percentages. If interest rates go from 5% to 7%, it increased by 2 percentage points (but 40% in relative terms).
How to calculate percentage increase?
(New minus Original) over Original times 100ใ
How do I calculate compound percentage changes?
When multiple percentage changes apply sequentially, multiply the factors rather than adding percentages. For example, a 20% increase followed by a 10% decrease: 1.20 ร 0.90 = 1.08, which is an 8% net increase (not 20% - 10% = 10%). Formula: New = Original ร (1 + p1/100) ร (1 + p2/100) ร ... This is important for sequential price changes, investment returns, and inflation adjustments.
