What is the Percentage Difference from 22 to 40?

From 22 to 40 is a 81.8182% increase

Step by step

  1. Difference: 40 − 22 = 18
  2. Divide by the starting value: 18 ÷ 22 = 0.818182
  3. Multiply by 100: 81.8182%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 22 to 40, a difference of 18. Compared with the starting value of 22, that difference is 81.8182%, so this is a 81.8182% increase.

The new value is 1.8182 times the old one: for every 100 at the start there are now 181.8182.

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 $22 to $40 has gone up by 81.8182%.
  • Pay: a wage that rises from $22 to $40 an hour is a 81.8182% pay rise.
  • Audiences: a channel that grows from 22 to 40 subscribers has grown by 81.8182%.

A quicker way

Find 1% of the starting value: 22 ÷ 100 = 0.22. The difference of 18 is 81.8182 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 22% to 40%, it changes by 18 percentage points, but by 81.8182% relative to where it started.

Check the answer

Work forwards from the start: 22 × (1 + 0.818182) = 22 × 1.818182 = 40. Getting 40 shows the answer is right.

Rounding

Rounded to a whole number the change is 82, to one decimal place 81.8 and to two decimal places 81.82. 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: 5 to 38

  1. Difference: 38 − 5 = 33
  2. Divide by the starting value: 33 ÷ 5 = 6.6
  3. Multiply by 100: 660%

Why the change back is different

A 81.8182% rise followed by a 81.8182% fall does not bring you back to 22: it gives 7.2727. The second percentage is taken of 40, not of 22, so to undo this change you need 45% instead.
