What is the Percentage Difference from 36 to 90?

From 36 to 90 is a 150% increase

Step by step

  1. Difference: 90 − 36 = 54
  2. Divide by the starting value: 54 ÷ 36 = 1.5
  3. Multiply by 100: 150%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 36 to 90, a difference of 54. Compared with the starting value of 36, that difference is 150%, so this is a 150% increase.

The new value is 2.5 times the old one: for every 100 at the start there are now 250. 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 $36 to $90 has gone up by 150%.
  • Pay: a wage that rises from $36 to $90 an hour is a 150% pay rise.
  • Audiences: a channel that grows from 36 to 90 subscribers has grown by 150%.

A quicker way

Find 1% of the starting value: 36 ÷ 100 = 0.36. The difference of 54 is 150 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 36% to 90%, it changes by 54 percentage points, but by 150% relative to where it started.

Check the answer

Work forwards from the start: 36 × (1 + 1.5) = 36 × 2.5 = 90. Getting 90 shows the answer is right.

Rounding

Rounded to a whole number the change is 150, to one decimal place 150.0 and to two decimal places 150.00. 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: 8 to 99

  1. Difference: 99 − 8 = 91
  2. Divide by the starting value: 91 ÷ 8 = 11.375
  3. Multiply by 100: 1,137.5%

Why the change back is different

A 150% rise followed by a 150% fall does not bring you back to 36: it gives -45. The second percentage is taken of 90, not of 36, so to undo this change you need 60% instead.

Other ways to ask this

Terms used on this page

  • Old value: the starting amount, used as the base of the percentage.
  • New value: the amount after the change.
  • Increase: a positive change: the new value is bigger.
  • Percentage point: the plain difference between two rates, not a relative change.

In Excel, Google Sheets or Numbers type =(90-36)/36*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%.
