What is the Percentage Difference from 75 to 73?

From 75 to 73 is a 2.6667% decrease

Step by step

  1. Difference: 73 − 75 = -2
  2. Divide by the starting value: -2 ÷ 75 = -0.026667
  3. Multiply by 100: -2.6667%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 75 to 73, a difference of 2. Compared with the starting value of 75, that difference is 2.6667%, so this is a 2.6667% decrease.

The new value is 97.3333% of the old one: for every 100 at the start there are now 97.3333, so 2.6667 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 $75 to $73 is a 2.6667% discount.
  • Weight: going from 75 to 73 kilograms is a loss of 2.6667% of the starting weight.
  • Results: if a team scores 73 points this season after 75 last season, its total has dropped by 2.6667%.

A quicker way

Find 1% of the starting value: 75 ÷ 100 = 0.75. The difference of 2 is 2.6667 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 75% to 73%, it changes by 2 percentage points, but by 2.6667% relative to where it started.

Check the answer

Work forwards from the start: 75 × (1 − 0.026667) = 75 × 0.973333 = 73. Getting 73 shows the answer is right.

Rounding

Rounded to a whole number the change is -3, to one decimal place -2.7 and to two decimal places -2.67. 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: 15 to 21

  1. Difference: 21 − 15 = 6
  2. Divide by the starting value: 6 ÷ 15 = 0.4
  3. Multiply by 100: 40%

Why the change back is different

A 2.6667% fall followed by a 2.6667% rise does not bring you back to 75: it gives 74.9467. The second percentage is taken of 73, not of 75, so to undo this change you need 2.7397% instead.
