What is the Percentage Difference from 23 to 28?

From 23 to 28 is a 21.7391% increase

Step by step

  1. Difference: 28 − 23 = 5
  2. Divide by the starting value: 5 ÷ 23 = 0.217391
  3. Multiply by 100: 21.7391%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 23 to 28, a difference of 5. Compared with the starting value of 23, that difference is 21.7391%, so this is a 21.7391% increase.

The new value is 1.2174 times the old one: for every 100 at the start there are now 121.7391.

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 $23 to $28 has gone up by 21.7391%.
  • Pay: a wage that rises from $23 to $28 an hour is a 21.7391% pay rise.
  • Audiences: a channel that grows from 23 to 28 subscribers has grown by 21.7391%.

A quicker way

Find 1% of the starting value: 23 ÷ 100 = 0.23. The difference of 5 is 21.7391 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 23% to 28%, it changes by 5 percentage points, but by 21.7391% relative to where it started.

Check the answer

Work forwards from the start: 23 × (1 + 0.217391) = 23 × 1.217391 = 28. Getting 28 shows the answer is right.

Rounding

Rounded to a whole number the change is 22, to one decimal place 21.7 and to two decimal places 21.74. 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 52

  1. Difference: 52 − 5 = 47
  2. Divide by the starting value: 47 ÷ 5 = 9.4
  3. Multiply by 100: 940%

Why the change back is different

A 21.7391% rise followed by a 21.7391% fall does not bring you back to 23: it gives 21.913. The second percentage is taken of 28, not of 23, so to undo this change you need 17.8571% instead.

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%.
