To do this I had to make up values for products the amount they would sell for and the amount they would cost to buy.

Conclusion

You will need to follow the same routine for typing in the information in the bought, buy cost and sell price fields. It should be noted that buy cost is worked out on a individual basis. Most products you sell will not be bought individually so you will need to divide the amount you get buy the cost to get an individual price. With things like coffee witch contain various separately bought items a price will have to be estimated for one. After that you will need to copy the formulas to the appropriate boxes. All the boxes that contained 0's are formulas. The first product in the list already has all its formulas in the right place. Only the first box in each formula column will contain a formula. You need to select it and right click to copy it. Then in the column bellow it highlight the empty cells right click and select paste special. Repeat this for all the formula columns. some formulas will need to be edited for the cells bellow your product fields. Highlight the cell bellow the total profit header, in the box near the top the formula =SUM will appear. You need to tell the sheet what is wants to add up. Look at the first and the last cells in the sales profit column. By looking at the sides you can find the grid references for those cells. ...read more.
