After you assign a name to a cell or cell range in your Excel 2013 worksheet, you can then choose the range name from the Use in Formula button’s drop-down menu on the Ribbon’s Formulas tab to paste it into the formulas that you build (Alt+MS).
For example, in the sample Sales Price table shown, after assigning the discount rate of 15% to the range name, discount_rate, you can create the formulas that calculate the amount of the sale discount. To do this, you multiply the retail price of each item by the discount_rate constant using the Use in Formula command button by following these steps:
- Make cell D3 active. 
- Type = (equal sign) to start the formula. 
- Click cell C3 to select the retail price for the first item and then type * (asterisk). - The formula on the Formula bar now reads, =C3*. 
- Click the Use in Formula button on the FORMULAS tab or press Alt+MS. - This action opens the drop-down menu on the Use in Formula button on which you can select the discount_rate range name. 
- Choose the name discount_rate from the Use in Formula button’s drop-down menu. - The formula now reads =C3*discount_rate on the Formula bar. 
- Click the Enter button on the Formula bar to input the formula in cell D3. - Now, all that remains is to copy the original formula down column D. 
- Drag the Fill handle in cell D3 down to cell D7 and release the mouse button to copy the formula and calculate the discount for the entire table.
