What is the Percentage Difference from 64 to 69?

From 64 to 69 is a 7.8125% increase

Step by step

  1. Difference: 69 − 64 = 5
  2. Divide by the starting value: 5 ÷ 64 = 0.078125
  3. Multiply by 100: 7.8125%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 64 to 69, a difference of 5. Compared with the starting value of 64, that difference is 7.8125%, so this is a 7.8125% increase.

The new value is 1.0781 times the old one: for every 100 at the start there are now 107.8125.

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 $64 to $69 has gone up by 7.8125%.
  • Pay: a wage that rises from $64 to $69 an hour is a 7.8125% pay rise.
  • Audiences: a channel that grows from 64 to 69 subscribers has grown by 7.8125%.

A quicker way

Find 1% of the starting value: 64 ÷ 100 = 0.64. The difference of 5 is 7.8125 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 64% to 69%, it changes by 5 percentage points, but by 7.8125% relative to where it started.

Check the answer

Work forwards from the start: 64 × (1 + 0.078125) = 64 × 1.078125 = 69. Getting 69 shows the answer is right.

Rounding

Rounded to a whole number the change is 8, to one decimal place 7.8 and to two decimal places 7.81. 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: 13 to 34

  1. Difference: 34 − 13 = 21
  2. Divide by the starting value: 21 ÷ 13 = 1.615385
  3. Multiply by 100: 161.5385%

Why the change back is different

A 7.8125% rise followed by a 7.8125% fall does not bring you back to 64: it gives 63.6094. The second percentage is taken of 69, not of 64, so to undo this change you need 7.2464% 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%.
