What is the Percentage Difference from 39 to 61?

From 39 to 61 is a 56.4103% increase

Step by step

  1. Difference: 61 − 39 = 22
  2. Divide by the starting value: 22 ÷ 39 = 0.564103
  3. Multiply by 100: 56.4103%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 39 to 61, a difference of 22. Compared with the starting value of 39, that difference is 56.4103%, so this is a 56.4103% increase.

The new value is 1.5641 times the old one: for every 100 at the start there are now 156.4103.

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 $39 to $61 has gone up by 56.4103%.
  • Pay: a wage that rises from $39 to $61 an hour is a 56.4103% pay rise.
  • Audiences: a channel that grows from 39 to 61 subscribers has grown by 56.4103%.

A quicker way

Find 1% of the starting value: 39 ÷ 100 = 0.39. The difference of 22 is 56.4103 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 39% to 61%, it changes by 22 percentage points, but by 56.4103% relative to where it started.

Check the answer

Work forwards from the start: 39 × (1 + 0.564103) = 39 × 1.564103 = 61. Getting 61 shows the answer is right.

Rounding

Rounded to a whole number the change is 56, to one decimal place 56.4 and to two decimal places 56.41. 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: 8 to 99

  1. Difference: 99 − 8 = 91
  2. Divide by the starting value: 91 ÷ 8 = 11.375
  3. Multiply by 100: 1,137.5%

Why the change back is different

A 56.4103% rise followed by a 56.4103% fall does not bring you back to 39: it gives 26.5897. The second percentage is taken of 61, not of 39, so to undo this change you need 36.0656% 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%.
