How to work out a percentage raise

Here is the method for working out what the result is from raising an amount by a set percentage. A is the initial value and B is the number of percent you want to increase A by:

  1. Work out what 1% of the original amount (A) is - we'll call this value C, to do this just divide it by 100: C (1%) = A / 100
  2. Multiplying this by the number of percent you want to increase it by (B): C × B = Amount to raise
  3. This gives you the value of the rise.
  4. Add the increase to the original amount to show the new value.

With the figures above you would do the following:
575 ÷ 100 = 5.75 (1% of the initial amount) So: 5.75 × 16 = 92 Then: 575 + 92 = 667. In other words, raising 575 by 16% is 667.
