What is the Percentage Difference from 19 to 20?

From 19 to 20 is a 5.2632% increase

Step by step

  1. Difference: 20 − 19 = 1
  2. Divide by the starting value: 1 ÷ 19 = 0.052632
  3. Multiply by 100: 5.2632%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 19 to 20, a difference of 1. Compared with the starting value of 19, that difference is 5.2632%, so this is a 5.2632% increase.

The new value is 1.0526 times the old one: for every 100 at the start there are now 105.2632.

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 $19 to $20 has gone up by 5.2632%.
  • Pay: a wage that rises from $19 to $20 an hour is a 5.2632% pay rise.
  • Audiences: a channel that grows from 19 to 20 subscribers has grown by 5.2632%.

A quicker way

Find 1% of the starting value: 19 ÷ 100 = 0.19. The difference of 1 is 5.2632 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 19% to 20%, it changes by 1 percentage points, but by 5.2632% relative to where it started.

Check the answer

Work forwards from the start: 19 × (1 + 0.052632) = 19 × 1.052632 = 20. Getting 20 shows the answer is right.

Rounding

Rounded to a whole number the change is 5, to one decimal place 5.3 and to two decimal places 5.26. 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: 4 to 59

  1. Difference: 59 − 4 = 55
  2. Divide by the starting value: 55 ÷ 4 = 13.75
  3. Multiply by 100: 1,375%

Why the change back is different

A 5.2632% rise followed by a 5.2632% fall does not bring you back to 19: it gives 18.9474. The second percentage is taken of 20, not of 19, so to undo this change you need 5% 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%.
