What is the Percentage Difference from 52 to 39?
From 52 to 39 is a 25% decrease
Step by step
- Difference: 39 − 52 = -13
- Divide by the starting value: -13 ÷ 52 = -0.25
- Multiply by 100: -25%
How the answer is worked out
Percentage change measures a difference against the value you started with. The value went from 52 to 39, a difference of 13. Compared with the starting value of 52, that difference is 25%, so this is a 25% decrease.
The new value is 75% of the old one: for every 100 at the start there are now 75, so 25 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 $52 to $39 is a 25% discount.
- Weight: going from 52 to 39 kilograms is a loss of 25% of the starting weight.
- Results: if a team scores 39 points this season after 52 last season, its total has dropped by 25%.
A quicker way
Find 1% of the starting value: 52 ÷ 100 = 0.52. The difference of 13 is 25 of those steps.
Percentage change is not the same as percentage points. If a rate moves from 52% to 39%, it changes by 13 percentage points, but by 25% relative to where it started.
Check the answer
Work forwards from the start: 52 × (1 − 0.25) = 52 × 0.75 = 39. Getting 39 shows the answer is right.
Rounding
Rounded to a whole number the change is -25, to one decimal place -25.0 and to two decimal places -25.00. 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: 10 to 99
- Difference: 99 − 10 = 89
- Divide by the starting value: 89 ÷ 10 = 8.9
- Multiply by 100: 890%
Why the change back is different
A 25% fall followed by a 25% rise does not bring you back to 52: it gives 48.75. The second percentage is taken of 39, not of 52, so to undo this change you need 33.3333% 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%.
