What is the Percentage Difference from 64 to 62?

From 64 to 62 is a 3.125% decrease

Step by step

  1. Difference: 62 − 64 = -2
  2. Divide by the starting value: -2 ÷ 64 = -0.03125
  3. Multiply by 100: -3.125%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 64 to 62, a difference of 2. Compared with the starting value of 64, that difference is 3.125%, so this is a 3.125% decrease.

The new value is 96.875% of the old one: for every 100 at the start there are now 96.875, so 3.125 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 $64 to $62 is a 3.125% discount.
  • Weight: going from 64 to 62 kilograms is a loss of 3.125% of the starting weight.
  • Results: if a team scores 62 points this season after 64 last season, its total has dropped by 3.125%.

A quicker way

Find 1% of the starting value: 64 ÷ 100 = 0.64. The difference of 2 is 3.125 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 64% to 62%, it changes by 2 percentage points, but by 3.125% relative to where it started.

Check the answer

Work forwards from the start: 64 × (1 − 0.03125) = 64 × 0.96875 = 62. Getting 62 shows the answer is right.

Rounding

Rounded to a whole number the change is -3, to one decimal place -3.1 and to two decimal places -3.13. 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: 12 to 78

  1. Difference: 78 − 12 = 66
  2. Divide by the starting value: 66 ÷ 12 = 5.5
  3. Multiply by 100: 550%

Why the change back is different

A 3.125% fall followed by a 3.125% rise does not bring you back to 64: it gives 63.9375. The second percentage is taken of 62, not of 64, so to undo this change you need 3.2258% instead.

  • Increase: a positive change: the new value is bigger.
  • Percentage point: the plain difference between two rates, not a relative change.

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%.
