What is the Percentage Difference from 75 to 57?
From 75 to 57 is a 24% decrease
Step by step
- Difference: 57 − 75 = -18
- Divide by the starting value: -18 ÷ 75 = -0.24
- Multiply by 100: -24%
How the answer is worked out
Percentage change measures a difference against the value you started with. The value went from 75 to 57, a difference of 18. Compared with the starting value of 75, that difference is 24%, so this is a 24% decrease.
The new value is 76% of the old one: for every 100 at the start there are now 76, so 24 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 $75 to $57 is a 24% discount.
- Weight: going from 75 to 57 kilograms is a loss of 24% of the starting weight.
- Results: if a team scores 57 points this season after 75 last season, its total has dropped by 24%.
A quicker way
Find 1% of the starting value: 75 ÷ 100 = 0.75. The difference of 18 is 24 of those steps.
Percentage change is not the same as percentage points. If a rate moves from 75% to 57%, it changes by 18 percentage points, but by 24% relative to where it started.
Check the answer
Work forwards from the start: 75 × (1 − 0.24) = 75 × 0.76 = 57. Getting 57 shows the answer is right.
Rounding
Rounded to a whole number the change is -24, to one decimal place -24.0 and to two decimal places -24.00. 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: 14 to 45
- Difference: 45 − 14 = 31
- Divide by the starting value: 31 ÷ 14 = 2.214286
- Multiply by 100: 221.4286%
Why the change back is different
A 24% fall followed by a 24% rise does not bring you back to 75: it gives 70.68. The second percentage is taken of 57, not of 75, so to undo this change you need 31.5789% 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%.
