This calculator requires the use of Javascript enabled and capable browsers. This script calculates the sales retail markup from a cost in three different and distinct methods. The first is a flat rate dollar amount added to cost. For instance if you purchase goods at $3.00 per unit in a special buy and wish to make $1.35 on each, it calculates a retail sales price of $4.35 by addition. The second is by points. Your special purchase cost is again $3.00 per unit and you wish to mark them up by 30 points; it calculates $4.29 as the retail. The formula is (cost / (1.00 - .points)) where ".points" is a decimal from 1 to 99. The third is a percentage of cost markup. Your special purchase cost is again $3.00 and you wish to mark each item up by 30%; it calculates to $3.90 as the sales price. The formula is (cost + (cost x percent)).

Enter the item cost and the markup value (no matter if it is percent, flat amount or points). Click the appropriate Calculate button; read the retail sales price and confirm the method of calculation. You may click on Clear Values and do another. (You do NOT enter the decimal for points; use the number of points you wish from 1 to 99. You MAY enter a decimal for a flat rate amount. You MAY enter a decimal for percent in that IF you wish to have 30 and a half percent as the markup value, it would be entered 30.5 in the markup value field.
