What is the Percentage Difference from 38 to 26?
From 38 to 26 is a 31.5789% decrease
Step by step
- Difference: 26 − 38 = -12
- Divide by the starting value: -12 ÷ 38 = -0.315789
- Multiply by 100: -31.5789%
How the answer is worked out
Percentage change measures a difference against the value you started with. The value went from 38 to 26, a difference of 12. Compared with the starting value of 38, that difference is 31.5789%, so this is a 31.5789% decrease.
The new value is 68.4211% of the old one: for every 100 at the start there are now 68.4211, so 31.5789 out of every 100 have gone.
Why calculate this?
Percentage change compares a new value with an old one regardless of size: price rises, growth, discounts, score changes.
- Sales: a price cut from $38 to $26 is a 31.5789% discount.
- Weight: going from 38 to 26 kilograms is a loss of 31.5789% of the starting weight.
- Results: if a team scores 26 points this season after 38 last season, its total has dropped by 31.5789%.
A quicker way
Find 1% of the starting value: 38 ÷ 100 = 0.38. The difference of 12 is 31.5789 of those steps.
Percentage change is not the same as percentage points. If a rate moves from 38% to 26%, it changes by 12 percentage points, but by 31.5789% relative to where it started.
Check the answer
Work forwards from the start: 38 × (1 − 0.315789) = 38 × 0.684211 = 26. Getting 26 shows the answer is right.
Rounding
Rounded to a whole number the change is -32, to one decimal place -31.6 and to two decimal places -31.58. 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 96
- Difference: 96 − 8 = 88
- Divide by the starting value: 88 ÷ 8 = 11
- Multiply by 100: 1,100%
Why the change back is different
A 31.5789% fall followed by a 31.5789% rise does not bring you back to 38: it gives 34.2105. The second percentage is taken of 26, not of 38, so to undo this change you need 46.1538% instead.
