What is the Percentage Difference from 5 to 50?

From 5 to 50 is a 900% increase

Step by step

  1. Difference: 50 − 5 = 45
  2. Divide by the starting value: 45 ÷ 5 = 9
  3. Multiply by 100: 900%

How the answer is worked out

Percentage change measures a difference against the value you started with. The value went from 5 to 50, a difference of 45. Compared with the starting value of 5, that difference is 900%, so this is a 900% increase.

The new value is 10 times the old one: for every 100 at the start there are now 1,000. 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 $5 to $50 has gone up by 900%.
  • Pay: a wage that rises from $5 to $50 an hour is a 900% pay rise.
  • Audiences: a channel that grows from 5 to 50 subscribers has grown by 900%.

A quicker way

Find 1% of the starting value: 5 ÷ 100 = 0.05. The difference of 45 is 900 of those steps.

Percentage change is not the same as percentage points. If a rate moves from 5% to 50%, it changes by 45 percentage points, but by 900% relative to where it started.

Check the answer

Work forwards from the start: 5 × (1 + 9) = 5 × 10 = 50. Getting 50 shows the answer is right.

Rounding

Rounded to a whole number the change is 900, to one decimal place 900.0 and to two decimal places 900.00. 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 21

  1. Difference: 21 − 2 = 19
  2. Divide by the starting value: 19 ÷ 2 = 9.5
  3. Multiply by 100: 950%

Why the change back is different

A 900% rise followed by a 900% fall does not bring you back to 5: it gives -400. The second percentage is taken of 50, not of 5, so to undo this change you need 90% instead.

Other ways to ask this

The same calculation is often asked in other words. All of these have the answer above:

  • Percentage increase from 5 to 50
  • What percent more is 50 than 5?
  • 5 to 50 as a percent change
  • How much did 5 grow going to 50, in percent?
  • Relative change between 5 and 50

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 =(50-5)/5*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%.
