What is the Percentage Difference from 56 to 87?
From 56 to 87 is a 55.3571% increase
Step by step
- Difference: 87 − 56 = 31
- Divide by the starting value: 31 ÷ 56 = 0.553571
- Multiply by 100: 55.3571%
How the answer is worked out
Percentage change measures a difference against the value you started with. The value went from 56 to 87, a difference of 31. Compared with the starting value of 56, that difference is 55.3571%, so this is a 55.3571% increase.
The new value is 1.5536 times the old one: for every 100 at the start there are now 155.3571.
Why calculate this?
Percentage change compares a new value with an old one regardless of size: price rises, growth, discounts, score changes.
- Prices: an item whose price rises from $56 to $87 has gone up by 55.3571%.
- Pay: a wage that rises from $56 to $87 an hour is a 55.3571% pay rise.
- Audiences: a channel that grows from 56 to 87 subscribers has grown by 55.3571%.
A quicker way
Find 1% of the starting value: 56 ÷ 100 = 0.56. The difference of 31 is 55.3571 of those steps.
Percentage change is not the same as percentage points. If a rate moves from 56% to 87%, it changes by 31 percentage points, but by 55.3571% relative to where it started.
Check the answer
Work forwards from the start: 56 × (1 + 0.553571) = 56 × 1.553571 = 87. Getting 87 shows the answer is right.
Rounding
Rounded to a whole number the change is 55, to one decimal place 55.4 and to two decimal places 55.36. Round only at the end: rounding halfway through a calculation can change the last digit.
The formula explained
percentage change = (new value − old value) ÷ old value × 100. A positive result is an increase and a negative result is a decrease. The old value is always the base, which is why the change from A to B and from B to A are different percentages.
Another worked example: 12 to 28
- Difference: 28 − 12 = 16
- Divide by the starting value: 16 ÷ 12 = 1.333333
- Multiply by 100: 133.3333%
Why the change back is different
A 55.3571% rise followed by a 55.3571% fall does not bring you back to 56: it gives 38.8393. The second percentage is taken of 87, not of 56, so to undo this change you need 35.6322% instead.
