What is the Percentage Difference from 39 to 41?

From 39 to 41 is a 5.1282% increase

Step by step

  1. Difference: 41 − 39 = 2
  2. Divide by the starting value: 2 ÷ 39 = 0.051282
  3. Multiply by 100: 5.1282%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 39 to 41, a difference of 2. Compared with the starting value of 39, that difference is 5.1282%, so this is a 5.1282% increase.

The new value is 1.0513 times the old one: for every 100 at the start there are now 105.1282.

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 $41 has gone up by 5.1282%.
  • Pay: a wage that rises from $39 to $41 an hour is a 5.1282% pay rise.
  • Audiences: a channel that grows from 39 to 41 subscribers has grown by 5.1282%.

A quicker way

Find 1% of the starting value: 39 ÷ 100 = 0.39. The difference of 2 is 5.1282 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 39% to 41%, it changes by 2 percentage points, but by 5.1282% relative to where it started.

Check the answer

Work forwards from the start: 39 × (1 + 0.051282) = 39 × 1.051282 = 41. Getting 41 shows the answer is right.

Rounding

Rounded to a whole number the change is 5, to one decimal place 5.1 and to two decimal places 5.13. 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: 8 to 69

  1. Difference: 69 − 8 = 61
  2. Divide by the starting value: 61 ÷ 8 = 7.625
  3. Multiply by 100: 762.5%

Why the change back is different

A 5.1282% rise followed by a 5.1282% fall does not bring you back to 39: it gives 38.8974. The second percentage is taken of 41, not of 39, so to undo this change you need 4.878% 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%.
