What is the Percentage Difference from 63 to 90?

From 63 to 90 is a 42.8571% increase

Step by step

  1. Difference: 90 − 63 = 27
  2. Divide by the starting value: 27 ÷ 63 = 0.428571
  3. Multiply by 100: 42.8571%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 63 to 90, a difference of 27. Compared with the starting value of 63, that difference is 42.8571%, so this is a 42.8571% increase.

The new value is 1.4286 times the old one: for every 100 at the start there are now 142.8571.

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 $90 has gone up by 42.8571%.
  • Pay: a wage that rises from $63 to $90 an hour is a 42.8571% pay rise.
  • Audiences: a channel that grows from 63 to 90 subscribers has grown by 42.8571%.

A quicker way

Find 1% of the starting value: 63 ÷ 100 = 0.63. The difference of 27 is 42.8571 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 63% to 90%, it changes by 27 percentage points, but by 42.8571% relative to where it started.

Check the answer

Work forwards from the start: 63 × (1 + 0.428571) = 63 × 1.428571 = 90. Getting 90 shows the answer is right.

Rounding

Rounded to a whole number the change is 43, to one decimal place 42.9 and to two decimal places 42.86. 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 82

  1. Difference: 82 − 13 = 69
  2. Divide by the starting value: 69 ÷ 13 = 5.307692
  3. Multiply by 100: 530.7692%

Why the change back is different

A 42.8571% rise followed by a 42.8571% fall does not bring you back to 63: it gives 51.4286. The second percentage is taken of 90, not of 63, so to undo this change you need 30% instead.

Common mistakes

Always divide by the starting value, not the new one. A rise from 40 to 50 is +25%, but the fall from 50 back to 40 is −20%.
