Decrease numbers by percentages of their values and calculate the absolute percentage change (difference)

How to calculate the new value of a number by decreasing it by percentage of its value and the absolute percentage change (difference)

  • Percentage decreased number = Initial value - Absolute percentage change (difference)
  • Absolute percentage change (difference) = Percentage decrease % × Initial value
  • Percentage decreased number = Initial value - Percentage decrease % × Initial value = (1 - Percentage decrease %) × Initial value
  • In conclusion:

    Percentage decreased number = (1 - Percentage decrease %) × Initial value

    Initial value = Percentage decreased number / (1 - Percentage decrease %)

    Absolute percentage change (difference) = Percentage decrease % × Initial value = New value - Initial value

Examples of calculations on how to decrease a number by percentage of its value and calculate the absolute percentage change:

  • If Percentage decrease % = 20%, (1 - Percentage decrease %) = 1 - 20% = 100/100 - 20/100 = 80/100 = 0.8 => Percentage decreased number = 0.8 × Initial value, and Initial value = Percentage decreased number / 0.8; Absolute percentage change (difference) = New value - Initial value;
  • If Percentage decrease % = 5%, (1 - Percentage decrease %) = 1 - 5% = 100/100 - 5/100 = 95/100 = 0.95 => Percentage decreased number = 0.95 × Initial value, and Initial value = Percentage decreased number / 0.95; Absolute percentage change (difference) = New value - Initial value;
  • If Percentage decrease % = 120%, (1 - Percentage decrease %) = 1 - 120% = 100/100 - 120/100 = -20/100 = -0.2 => Percentage decreased number = -0.2 × Initial value, and Initial value = Percentage decreased number / -0.2; Absolute percentage change (difference) = New value - Initial value;
  • If Percentage decrease % = -30%, (1 - Percentage decrease %) = 1 - (-30%) = 1 + 30% = 100/100 + 30/100 = 130/100 = 1.3 => Percentage decreased number = 1.3 × Initial value, and Initial value = Percentage decreased number / 1.3; this is in fact a percentage increase of the initial number; Absolute percentage change (difference) = New value - Initial value.
