      Enter Your Data

    Start by entering the original number and the percentage you want to add.

    Place them in separate cells for easier calculations.

    • Enter the original number in one cell
    • Enter the percentage in another cell
    • Format the percentage cell as a percentage if needed

    1. Use a Simple Formula

    To add a percentage to a number, multiply the number by one plus the percentage.

    This increases the original value by the specified percentage.

    • Use the formula: =A1*(1+B1)
    • A1 contains the original number
    • B1 contains the percentage

    1. Calculate the Increased Amount

    Press Enter after typing the formula.

    Excel will automatically calculate the new value.

    • Check that the formula is correct
    • Press Enter to display the result
    • Verify the calculation if necessary

    1. Apply the Formula to Multiple Cells

    If you have a list of numbers, you can copy the formula down a column.

    This allows Excel to calculate multiple values quickly.

    • Select the formula cell
    • Drag the fill handle downward
    • Apply the calculation to other rows

    1. Format the Results

    You can format the result as a number, currency, or other format depending on your needs.

    This makes the worksheet easier to read.

    • Select the result cells
    • Choose the desired number format
    • Adjust decimal places if needed

    Example

    If cell A1 contains 100 and cell B1 contains 10%, use:

    =A1*(1+B1)

    The result will be 110.
