What is the Percentage Difference from 30 to 46?

From 30 to 46 is a 53.3333% increase

Step by step

  1. Difference: 46 − 30 = 16
  2. Divide by the starting value: 16 ÷ 30 = 0.533333
  3. Multiply by 100: 53.3333%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 30 to 46, a difference of 16. Compared with the starting value of 30, that difference is 53.3333%, so this is a 53.3333% increase.

The new value is 1.5333 times the old one: for every 100 at the start there are now 153.3333.

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 $30 to $46 has gone up by 53.3333%.
  • Pay: a wage that rises from $30 to $46 an hour is a 53.3333% pay rise.
  • Audiences: a channel that grows from 30 to 46 subscribers has grown by 53.3333%.

A quicker way

Find 1% of the starting value: 30 ÷ 100 = 0.3. The difference of 16 is 53.3333 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 30% to 46%, it changes by 16 percentage points, but by 53.3333% relative to where it started.

Check the answer

Work forwards from the start: 30 × (1 + 0.533333) = 30 × 1.533333 = 46. Getting 46 shows the answer is right.

Rounding

Rounded to a whole number the change is 53, to one decimal place 53.3 and to two decimal places 53.33. 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: 6 to 38

  1. Difference: 38 − 6 = 32
  2. Divide by the starting value: 32 ÷ 6 = 5.333333
  3. Multiply by 100: 533.3333%

Why the change back is different

A 53.3333% rise followed by a 53.3333% fall does not bring you back to 30: it gives 21.4667. The second percentage is taken of 46, not of 30, so to undo this change you need 34.7826% 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%.
