Percentage Change Calculator
Calculate percentage increase or decrease.
How much did it change?
Percentage change is the difference divided by the original value: from 40 to 50 is a 25% increase. This handles both increases and decreases and shows the direction clearly.
It is essential for reading growth honestly: a jump from 2 to 4 is a 100% increase, while 98 to 100 is only about 2%, even though both rose by two.
Base matters
The same absolute change is a bigger percentage off a smaller base, so watch what the original is. Your values are never uploaded.
