What is the Percentage Difference from 32 to 8?
From 32 to 8 is a 75% decrease
Step by step
- Difference: 8 − 32 = -24
- Divide by the starting value: -24 ÷ 32 = -0.75
- Multiply by 100: -75%
How the answer is worked out
Percentage change measures a difference against the value you started with. The value went from 32 to 8, a difference of 24. Compared with the starting value of 32, that difference is 75%, so this is a 75% decrease.
The new value is 25% of the old one: for every 100 at the start there are now 25, so 75 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 $32 to $8 is a 75% discount.
- Weight: going from 32 to 8 kilograms is a loss of 75% of the starting weight.
- Results: if a team scores 8 points this season after 32 last season, its total has dropped by 75%.
A quicker way
Find 1% of the starting value: 32 ÷ 100 = 0.32. The difference of 24 is 75 of those steps.
Percentage change is not the same as percentage points. If a rate moves from 32% to 8%, it changes by 24 percentage points, but by 75% relative to where it started.
Check the answer
Work forwards from the start: 32 × (1 − 0.75) = 32 × 0.25 = 8. Getting 8 shows the answer is right.
Rounding
Rounded to a whole number the change is -75, to one decimal place -75.0 and to two decimal places -75.00. 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: 7 to 75
- Difference: 75 − 7 = 68
- Divide by the starting value: 68 ÷ 7 = 9.714286
- Multiply by 100: 971.4286%
Why the change back is different
A 75% fall followed by a 75% rise does not bring you back to 32: it gives 14. The second percentage is taken of 8, not of 32, so to undo this change you need 300% instead.

Doing it in a spreadsheet
In Excel, Google Sheets or Numbers type =(8-32)/32*100 into any cell. Replace the numbers with cell references (for example A1 and B1) to reuse the formula for a whole column.
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%.
