What is the Percentage Difference from 63 to 84?
From 63 to 84 is a 33.3333% increase
Step by step
- Difference: 84 − 63 = 21
- Divide by the starting value: 21 ÷ 63 = 0.333333
- Multiply by 100: 33.3333%
How the answer is worked out
Percentage change measures a difference against the value you started with. The value went from 63 to 84, a difference of 21. Compared with the starting value of 63, that difference is 33.3333%, so this is a 33.3333% increase.
The new value is 1.3333 times the old one: for every 100 at the start there are now 133.3333.
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 $63 to $84 has gone up by 33.3333%.
- Pay: a wage that rises from $63 to $84 an hour is a 33.3333% pay rise.
- Audiences: a channel that grows from 63 to 84 subscribers has grown by 33.3333%.
A quicker way
Find 1% of the starting value: 63 ÷ 100 = 0.63. The difference of 21 is 33.3333 of those steps.
Percentage change is not the same as percentage points. If a rate moves from 63% to 84%, it changes by 21 percentage points, but by 33.3333% relative to where it started.
Check the answer
Work forwards from the start: 63 × (1 + 0.333333) = 63 × 1.333333 = 84. Getting 84 shows the answer is right.
Rounding
Rounded to a whole number the change is 33, to one decimal place 33.3 and to two decimal places 33.33. 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: 13 to 92
- Difference: 92 − 13 = 79
- Divide by the starting value: 79 ÷ 13 = 6.076923
- Multiply by 100: 607.6923%
Why the change back is different
A 33.3333% rise followed by a 33.3333% fall does not bring you back to 63: it gives 56. The second percentage is taken of 84, not of 63, so to undo this change you need 25% instead.
