What is the Percentage Difference from 44 to 42?

From 44 to 42 is a 4.5455% decrease

Step by step

  1. Difference: 42 − 44 = -2
  2. Divide by the starting value: -2 ÷ 44 = -0.045455
  3. Multiply by 100: -4.5455%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 44 to 42, a difference of 2. Compared with the starting value of 44, that difference is 4.5455%, so this is a 4.5455% decrease.

The new value is 95.4545% of the old one: for every 100 at the start there are now 95.4545, so 4.5455 out of every 100 have gone.

Why calculate this?

Percentage change compares a new value with an old one regardless of size: price rises, growth, discounts, score changes.

  • Sales: a price cut from $44 to $42 is a 4.5455% discount.
  • Weight: going from 44 to 42 kilograms is a loss of 4.5455% of the starting weight.
  • Results: if a team scores 42 points this season after 44 last season, its total has dropped by 4.5455%.

A quicker way

Find 1% of the starting value: 44 ÷ 100 = 0.44. The difference of 2 is 4.5455 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 44% to 42%, it changes by 2 percentage points, but by 4.5455% relative to where it started.

Check the answer

Work forwards from the start: 44 × (1 − 0.045455) = 44 × 0.954545 = 42. Getting 42 shows the answer is right.

Rounding

Rounded to a whole number the change is -5, to one decimal place -4.5 and to two decimal places -4.55. 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: 9 to 82

  1. Difference: 82 − 9 = 73
  2. Divide by the starting value: 73 ÷ 9 = 8.111111
  3. Multiply by 100: 811.1111%

Why the change back is different

A 4.5455% fall followed by a 4.5455% rise does not bring you back to 44: it gives 43.9091. The second percentage is taken of 42, not of 44, so to undo this change you need 4.7619% instead.
