What is the Percentage Difference from 48 to 87?

From 48 to 87 is a 81.25% increase

Step by step

  1. Difference: 87 − 48 = 39
  2. Divide by the starting value: 39 ÷ 48 = 0.8125
  3. Multiply by 100: 81.25%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 48 to 87, a difference of 39. Compared with the starting value of 48, that difference is 81.25%, so this is a 81.25% increase.

The new value is 1.8125 times the old one: for every 100 at the start there are now 181.25.

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 $48 to $87 has gone up by 81.25%.
  • Pay: a wage that rises from $48 to $87 an hour is a 81.25% pay rise.
  • Audiences: a channel that grows from 48 to 87 subscribers has grown by 81.25%.

A quicker way

Find 1% of the starting value: 48 ÷ 100 = 0.48. The difference of 39 is 81.25 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 48% to 87%, it changes by 39 percentage points, but by 81.25% relative to where it started.

Check the answer

Work forwards from the start: 48 × (1 + 0.8125) = 48 × 1.8125 = 87. Getting 87 shows the answer is right.

Rounding

Rounded to a whole number the change is 81, to one decimal place 81.3 and to two decimal places 81.25. 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: 10 to 68

  1. Difference: 68 − 10 = 58
  2. Divide by the starting value: 58 ÷ 10 = 5.8
  3. Multiply by 100: 580%

Why the change back is different

A 81.25% rise followed by a 81.25% fall does not bring you back to 48: it gives 16.3125. The second percentage is taken of 87, not of 48, so to undo this change you need 44.8276% instead.
