What is the Percentage Difference from 50 to 68?
From 50 to 68 is a 36% increase
Step by step
- Difference: 68 − 50 = 18
- Divide by the starting value: 18 ÷ 50 = 0.36
- Multiply by 100: 36%
How the answer is worked out
Percentage change measures a difference against the value you started with. The value went from 50 to 68, a difference of 18. Compared with the starting value of 50, that difference is 36%, so this is a 36% increase.
The new value is 1.36 times the old one: for every 100 at the start there are now 136.
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 $50 to $68 has gone up by 36%.
- Pay: a wage that rises from $50 to $68 an hour is a 36% pay rise.
- Audiences: a channel that grows from 50 to 68 subscribers has grown by 36%.
A quicker way
Find 1% of the starting value: 50 ÷ 100 = 0.5. The difference of 18 is 36 of those steps.
Percentage change is not the same as percentage points. If a rate moves from 50% to 68%, it changes by 18 percentage points, but by 36% relative to where it started.
Check the answer
Work forwards from the start: 50 × (1 + 0.36) = 50 × 1.36 = 68. Getting 68 shows the answer is right.
Rounding
Rounded to a whole number the change is 36, to one decimal place 36.0 and to two decimal places 36.00. 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 48
- Difference: 48 − 10 = 38
- Divide by the starting value: 38 ÷ 10 = 3.8
- Multiply by 100: 380%
Why the change back is different
A 36% rise followed by a 36% fall does not bring you back to 50: it gives 43.52. The second percentage is taken of 68, not of 50, so to undo this change you need 26.4706% instead.

In Excel, Google Sheets or Numbers type =(68-50)/50*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%.
