Calculating Percentage

I need to often be reminded of how to calculate a percentage.  The context here is that I want a progress bar in one of my programs.


To determine what percent a number is of a total number:
copyraw
(Progress So Far / Total Progress Units) * 100 = %
or
(Net Amount / Gross Amount) * 100 = %

eg. (12 steps / 30 steps) * 100 = 40%   ie. 12 steps of 30 is 40% progress
eg. ($8 / $10) * 100 = 80%              ie. $8 of $10 is 80%
  1.  (Progress So Far / Total Progress Units) * 100 = 
  2.  or 
  3.  (Net Amount / Gross Amount) * 100 = 
  4.   
  5.  eg. (12 steps / 30 steps) * 100 = 40%   ie. 12 steps of 30 is 40% progress 
  6.  eg. ($8 / $10) * 100 = 80%              ie. $8 of $10 is 80

To determine the percent (adjustment level) given the RRP and the price you're selling at:
copyraw
((Agreed Price - Usual Price) * 100) / Usual Price = %

eg. ($10 - $8) * 100 / $8 = +25%       ie. selling an $8 product at $10 is an increase of 25%
eg. ($8 - $10) * 100 / $10 = -20%      ie. selling a product at $8 when it usually costs $10 is a discount of 20%
eg. ($7,562.50 - $8,281.80) * 100 / $8,281.80 = -8.69%
  1.  ((Agreed Price - Usual Price) * 100) / Usual Price = 
  2.   
  3.  eg. ($10 - $8) * 100 / $8 = +25%       ie. selling an $8 product at $10 is an increase of 25
  4.  eg. ($8 - $10) * 100 / $10 = -20%      ie. selling a product at $8 when it usually costs $10 is a discount of 20
  5.  eg. ($7,562.50 - $8,281.80) * 100 / $8,281.80 = -8.69

To determine the amount given the percentage and total amount:
copyraw
(Discount / 100) * Usual Price = Discounted Price

eg. (20 / 100) * $80 = $16       ie. 20% of $80 is $16
  1.  (Discount / 100) * Usual Price = Discounted Price 
  2.   
  3.  eg. (20 / 100) * $80 = $16       ie. 20% of $80 is $16 

To determine the percent given two percentages:
copyraw
((Percentage 1 / 100) * (Percentage 2 / 100)) * 100 = %

eg. (50/100) * (40/100) = 0.5 x 0.4 = 0.2 * 100 = +20%       ie. 50% of a 40% sale is 20%
  1.  ((Percentage 1 / 100) * (Percentage 2 / 100)) * 100 = 
  2.   
  3.  eg. (50/100) * (40/100) = 0.5 x 0.4 = 0.2 * 100 = +20%       ie. 50% of a 40% sale is 20

Opportunities won vs opportunities lost:
copyraw
Percentage = Won / (Won + Lost) * 100

eg. 50% = 1 / (1 + 1) * 100
  1.  Percentage = Won / (Won + Lost) * 100 
  2.   
  3.  eg. 50% = 1 / (1 + 1) * 100 

Opportunities won vs total:
copyraw
Total = Won + Lost + Other
Percentage = Won / Total * 100

eg. 33.33% = 1 / (1 + 1 + 1) * 100
  1.  Total = Won + Lost + Other 
  2.  Percentage = Won / Total * 100 
  3.   
  4.  eg. 33.33% = 1 / (1 + 1 + 1) * 100 

Markup Margin Percentage:
copyraw
( Sell - Cost ) / Cost * 100 = Markup Percent

eg. ( 75 - 50 ) / 50 * 100 = 50%
  1.  ( Sell - Cost ) / Cost * 100 = Markup Percent 
  2.   
  3.  eg. ( 75 - 50 ) / 50 * 100 = 50

Gross Margin Percentage:
copyraw
( Sell - Cost ) = Gross Profit
( Sell - Cost ) / Sell * 100 = Gross Margin Percent

eg. ( 75 - 50 ) / 75 * 100 = 33.33%
  1.  ( Sell - Cost ) = Gross Profit 
  2.  ( Sell - Cost ) / Sell * 100 = Gross Margin Percent 
  3.   
  4.  eg. ( 75 - 50 ) / 75 * 100 = 33.33

Margin Percentage With Discount Applied:
copyraw
((( Sell * Quantity ) - Discount ) - ( Cost * Quantity )) / (( Sell * Quantity ) - Discount ) * 100

eg. ( $100 * 1 ) - $20 - ( $50 * 1 )  / ( $100 * 1 ) - $20 * 100 = 37.5%
eg. ( $120 * 2 ) - $40 - ( $50 * 1 )  / ( $120 * 2 ) - $40 * 100 = 50%
  1.  ((( Sell * Quantity ) - Discount ) - ( Cost * Quantity )) / (( Sell * Quantity ) - Discount ) * 100 
  2.   
  3.  eg. ( $100 * 1 ) - $20 - ( $50 * 1 )  / ( $100 * 1 ) - $20 * 100 = 37.5
  4.  eg. ( $120 * 2 ) - $40 - ( $50 * 1 )  / ( $120 * 2 ) - $40 * 100 = 50
