Scenario
Adjusting the remaining percentages in a dataset to add up to exactly 100% after removing a specific share.
Observed behavior
The current percentages sum to less than 100% due to the removed share, requiring a proportional formula recalculation to scale them up correctly.
Before you start

Ensure that the remaining original percentages are organized in a continuous column or row without blank cells to easily apply the absolute SUM formula.

Solution 1Recommended

Use Proportional Division to Recalculate Percentages

Divide each remaining owner's original percentage by the sum of all remaining percentages to get the adjusted proportional share.

By dividing the individual value by the total of the remaining pool, you can quickly distribute the missing percentage proportionally. Using absolute references ensures the total sum denominator does not change when dragging the formula.

1
Organize the remaining percentages

List the original percentages of the remaining owners in a single column, for example in cells A2, A3, and A4.

2
Apply the proportional formula

In cell B2, enter the formula =A2/SUM($A$2:$A$4). This calculates the new weight of the first remaining owner relative to the new total.

3
Fill down the formula

Click and drag the fill handle from cell B2 down to cell B4. The percentages in column B will now total exactly 100%.

4
Calculate the payment distribution

In an adjacent cell (e.g., C2), multiply the newly adjusted percentage by the payout amount using the formula =B2*1000. Drag this down to calculate everyone's exact share.

5
Format decimal precision

Select the newly calculated cells, right-click, and choose 'Format Cells'. Increase the decimal places displayed to view exact values and avoid rounding discrepancies.

Avoid Precision Errors: Do not enable 'Set precision as displayed' in your workbook options, as this permanently alters underlying data based on formatting and can cause your totals to drift away from exactly 100%.

Frequently Asked Questions

Why do my recalculated percentages total 99.9% instead of exactly 100%?

This is almost always a display issue caused by cell rounding. Increase the decimal places in the cell formatting to at least two places to verify the math, and ensure 'Set precision as displayed' is turned off in your spreadsheet settings.

How do I lock the SUM range so it doesn't shift when I drag the formula?

You must use absolute cell references for the total sum range. Highlight the range A2:A4 in your formula bar and press the F4 key on your keyboard. This adds dollar signs ($A$2:$A$4), locking the range in place.

Does this formula work if my data is arranged horizontally?

Yes. If your original percentages are in row 2 from column B to D, simply adjust the formula to =B2/SUM($B$2:$D$2) and drag the fill handle horizontally.
