What is the Percentage Difference from 9 to 36?
From 9 to 36 is a 300% increase
Step by step
- Difference: 36 − 9 = 27
- Divide by the starting value: 27 ÷ 9 = 3
- Multiply by 100: 300%
How the answer is worked out
Percentage change measures a difference against the value you started with. The value went from 9 to 36, a difference of 27. Compared with the starting value of 9, that difference is 300%, so this is a 300% increase.
The new value is 4 times the old one: for every 100 at the start there are now 400. The value has more than doubled.
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 $9 to $36 has gone up by 300%.
- Pay: a wage that rises from $9 to $36 an hour is a 300% pay rise.
- Audiences: a channel that grows from 9 to 36 subscribers has grown by 300%.
A quicker way
Find 1% of the starting value: 9 ÷ 100 = 0.09. The difference of 27 is 300 of those steps.
Percentage change is not the same as percentage points. If a rate moves from 9% to 36%, it changes by 27 percentage points, but by 300% relative to where it started.
Check the answer
Work forwards from the start: 9 × (1 + 3) = 9 × 4 = 36. Getting 36 shows the answer is right.
Rounding
Rounded to a whole number the change is 300, to one decimal place 300.0 and to two decimal places 300.00. 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: 2 to 89
- Difference: 89 − 2 = 87
- Divide by the starting value: 87 ÷ 2 = 43.5
- Multiply by 100: 4,350%
Why the change back is different
A 300% rise followed by a 300% fall does not bring you back to 9: it gives -72. The second percentage is taken of 36, not of 9, so to undo this change you need 75% instead.

Doing it in a spreadsheet
In Excel, Google Sheets or Numbers type =(36-9)/9*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%.
