What is the Percentage Difference from 79 to 84?

From 79 to 84 is a 6.3291% increase

Step by step

  1. Difference: 84 − 79 = 5
  2. Divide by the starting value: 5 ÷ 79 = 0.063291
  3. Multiply by 100: 6.3291%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 79 to 84, a difference of 5. Compared with the starting value of 79, that difference is 6.3291%, so this is a 6.3291% increase.

The new value is 1.0633 times the old one: for every 100 at the start there are now 106.3291.

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 $79 to $84 has gone up by 6.3291%.
  • Pay: a wage that rises from $79 to $84 an hour is a 6.3291% pay rise.
  • Audiences: a channel that grows from 79 to 84 subscribers has grown by 6.3291%.

A quicker way

Find 1% of the starting value: 79 ÷ 100 = 0.79. The difference of 5 is 6.3291 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 79% to 84%, it changes by 5 percentage points, but by 6.3291% relative to where it started.

Check the answer

Work forwards from the start: 79 × (1 + 0.063291) = 79 × 1.063291 = 84. Getting 84 shows the answer is right.

Rounding

Rounded to a whole number the change is 6, to one decimal place 6.3 and to two decimal places 6.33. 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 85

  1. Difference: 85 − 15 = 70
  2. Divide by the starting value: 70 ÷ 15 = 4.666667
  3. Multiply by 100: 466.6667%

Why the change back is different

A 6.3291% rise followed by a 6.3291% fall does not bring you back to 79: it gives 78.6835. The second percentage is taken of 84, not of 79, so to undo this change you need 5.9524% instead.
