Tips
Small bases exaggerate: growing from 2 to 4 sales is +100% but only +2 sales — always pair the percent with the absolute number the tool shows.
Frequently Asked Questions
How is percent increase calculated?
(New − original) ÷ original × 100.
What is the difference from percentage change?
Percent increase assumes growth; percentage change handles both directions with a sign.
Why can’t the original be zero?
Division by zero is undefined — growth from nothing can’t be expressed as a percent of zero.
Is a 100% increase the same as doubling?
Exactly — 100% increase means twice the original; 200% means triple.
