Subtraction Formula
- Excel does not have a dedicated subtraction function, but subtraction is performed using the minus sign (-).
- The basic formula for subtraction is:
=A1-B1, where A1 is the minuend and B1 is the subtrahend. - It is a fundamental operation used in financial calculations, data analysis, and reports.
How to Subtract in Excel
To perform subtraction in Excel, follow these steps:
- Select the cell where you want the result.
- Enter the formula using the minus (-) operator. Example:
=A2-B2. - Press Enter to see the result.
- Drag the fill handle down if you want to apply the formula to multiple rows.

Subtract Cells
- To subtract one cell from another:
=A1-B1 - To subtract multiple cells:
=A1-B1-C1 - Using parentheses ensures proper order of operations:
=(A1-B1)-C1
Subtract Multiple Cells
- If you need to subtract multiple numbers from a value, you can use:
=A1-SUM(B1:B3) - This method ensures that all values in the selected range are subtracted from A1.
Subtract Two Columns
| A (Value 1) | B (Value 2) | Subtraction Formula |
|---|---|---|
| 100 | 50 | =A2-B2 |
| 200 | 80 | =A3-B3 |
| 500 | 300 | =A4-B4 |
Subtract Percentages
- To subtract a percentage from a value:
=A1*(1-B1/100) - Example: If A1 is 500 and B1 is 20%, the formula
=500*(1-20/100)results in 400.
Subtract Dates
- To find the difference between two dates:
=B1-A1 - This returns the number of days between the two dates.
Subtract Times
- To subtract time values:
=B1-A1 - Excel stores time as fractions of a day, so the result may need formatting.
Subtract Matrices
- Excel supports matrix subtraction using array formulas.
- Example:
=A1:A3 - B1:B3(Ctrl+Shift+Enter for array formulas in older Excel versions).
Subtract Text Strings
- To remove specific text:
=SUBSTITUTE(A1, "unwanted text", "") - This is useful in data cleaning for text manipulation.
