Excel is a great tool for automating numerical tasks. It is as basic as arithmetic and as complex as amortisation. The program puts calculating tools to use, embedding math into the spreadsheet so the results of your calculations appear instantaneously. It does this with formulas. A formula or equation is typed right into a cell. The program performs the operation on the data you enter and shows the numerical result in your cell. Once you have the basic formula set, you can even copy that formula anywhere on the spreadsheet. This way, you can repeat the process as you need to, figuring many percentage savings at once.

• Excel is a great tool for automating numerical tasks.
• The program performs the operation on the data you enter and shows the numerical result in your cell.

Enter your data. In cell A2, type the item's name. In cell B2, enter its original price. In cell C2, enter the discounted price. In cell D2, the cost savings appears. In cell E2, the percentage savings appears.

• In cell A2, type the item's name.
• In cell C2, enter the discounted price.

Extend your table for more cost savings calculations. Go to cell D2. Select "Edit" from the top menu. Click "Copy." Click in cell D3 and drag downward in the D column, highlighting as many cells as you need for your data. Select "Edit" from the top menu bar. Click "Paste." This copies the formula into the cells. It does not copy specific data.

• Copy the percentage calculation.
• Select "Edit" from the top menu.
