What is the Percentage Difference from 82 to 76?

From 82 to 76 is a 7.3171% decrease

Step by step

  1. Difference: 76 − 82 = -6
  2. Divide by the starting value: -6 ÷ 82 = -0.073171
  3. Multiply by 100: -7.3171%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 82 to 76, a difference of 6. Compared with the starting value of 82, that difference is 7.3171%, so this is a 7.3171% decrease.

The new value is 92.6829% of the old one: for every 100 at the start there are now 92.6829, so 7.3171 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 $82 to $76 is a 7.3171% discount.
  • Weight: going from 82 to 76 kilograms is a loss of 7.3171% of the starting weight.
  • Results: if a team scores 76 points this season after 82 last season, its total has dropped by 7.3171%.

A quicker way

Find 1% of the starting value: 82 ÷ 100 = 0.82. The difference of 6 is 7.3171 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 82% to 76%, it changes by 6 percentage points, but by 7.3171% relative to where it started.

Check the answer

Work forwards from the start: 82 × (1 − 0.073171) = 82 × 0.926829 = 76. Getting 76 shows the answer is right.

Rounding

Rounded to a whole number the change is -7, to one decimal place -7.3 and to two decimal places -7.32. 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: 17 to 73

  1. Difference: 73 − 17 = 56
  2. Divide by the starting value: 56 ÷ 17 = 3.294118
  3. Multiply by 100: 329.4118%

Why the change back is different

A 7.3171% fall followed by a 7.3171% rise does not bring you back to 82: it gives 81.561. The second percentage is taken of 76, not of 82, so to undo this change you need 7.8947% 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%.
