How to Subtract in Excel

1. Introduction to Subtraction in Excel

Subtraction is one of the most essential calculations in Excel, used for everything from budgeting to data analysis. Unlike addition, Excel doesn’t have a dedicated “SUBTRACT” function—but that’s no problem. You can perform subtraction using simple operators, cell references, or combined functions, depending on your needs.

Whether you’re subtracting two numbers, entire columns, dates, or percentages, Excel offers flexible methods to get accurate results. This guide covers beginner-friendly steps to advanced techniques, ensuring you can handle any subtraction task in Excel—no prior expertise required.

2. Basic Methods to Subtract in Excel

2.1 Subtract Two Numbers Directly

The simplest way to subtract in Excel is using the minus sign (-) operator. This works for hardcoded numbers or quick calculations.

  • Step 1: Click the cell where you want the result to appear.
  • Step 2: Type = (equals sign) to start the formula.
  • Step 3: Enter the minuend (number to subtract from), followed by -, then the subtrahend (number to subtract).
  • Example: =150 - 75 returns 75. Press Enter to see the result.

2.2 Subtract One Cell from Another

Using cell references (e.g., A1, B2) instead of hardcoded numbers makes your formulas dynamic—they update automatically if the cell values change.

  • Step 1: Let’s say cell A2 contains 200 (minuend) and cell B2 contains 80 (subtrahend).
  • Step 2: In cell C2, type =A2 - B2.
  • Step 3: Press Enter—cell C2 will display 120, the difference between A2 and B2.

2.3 Subtract Multiple Cells in Excel

To subtract more than two cells, extend the basic formula with additional minus signs and cell references.

  • Example: If you want to subtract B2, C2, and D2 from A2, use =A2 - B2 - C2 - D2.
  • For efficiency with large datasets, combine the SUM function with negative values: =A2 - SUM(B2:D2). This sums the subtrahends first, then subtracts the total from A2.

3. Advanced Subtraction Techniques in Excel

3.1 Subtract Entire Columns or Rows

Subtracting columns or rows saves time when working with large datasets. Here’s how to do it:

  • Subtract Columns: In the first cell of the result column (e.g., C2), enter =A2 - B2. Hover over the cell’s bottom-right corner until the cursor becomes a black cross (fill handle), then drag down to apply the formula to all rows.
  • Subtract Rows: For horizontal subtraction, enter =B1 - A1 in cell C1. Drag the fill handle to the right to subtract corresponding values across rows.

3.2 Subtract a Fixed Number from a Column

To subtract the same number from every cell in a column, use absolute cell references (denoted with $) to lock the fixed number’s cell.

  • Example: If you want to subtract the value in cell D1 (e.g., 50) from all cells in column A:
    • In cell B2, type =A2 - $D$1.
    • Drag the fill handle down—all cells in column B will subtract the fixed value in D1.

3.3 Subtract Dates in Excel

Subtracting dates helps calculate durations (e.g., days between two events) or adjust timelines.

  • Basic Date Subtraction: Enter two dates in cells (e.g., A2 = 01/01/2025, B2 = 01/15/2025). In cell C2, type =B2 - A2 to get the number of days between them (14 days).
  • Calculate Years/Months Between Dates: Use the DATEDIF function for specific units:
    • Days: =DATEDIF(A2, B2, "d")
    • Months: =DATEDIF(A2, B2, "m")
    • Years: =DATEDIF(A2, B2, "y")
  • Adjust Dates by Days/Months: Subtract days directly (e.g., =A2 - 10 for 10 days earlier) or use EDATE for months: =EDATE(A2, -3) subtracts 3 months from the date in A2.

3.4 Subtract Percentages in Excel

Subtracting percentages is useful for discounts, tax deductions, or rate changes.

  • Example: To subtract 15% from the value in cell A2 (e.g., 500):
    • Formula: =A2 - (A2 * 15%) or simplified =A2 * (1 - 0.15)
    • Result: 425 (500 minus 15% of 500)

4. Common Errors When Subtracting in Excel (and How to Fix Them)

4.1 #VALUE! Error

This error occurs if you try to subtract text from a number or use an incorrect list separator.

  • Fix 1: Ensure all referenced cells contain numbers (not text or blank spaces).
  • Fix 2: Check your region settings—if the list separator is set to -, change it to a comma or semicolon in your computer’s region control panel.

4.2 Incorrect Date Results

Dates in Excel are stored as serial numbers, so results might appear as numbers instead of dates.

  • Fix: Select the result cell, right-click, choose “Format Cells,” and select a date format (e.g., MM/DD/YYYY).

4.3 Formula Not Updating

If your formula doesn’t change when cell values are updated, you might be using hardcoded numbers instead of cell references.

  • Fix: Replace hardcoded numbers with cell references (e.g., use =A2 - B2 instead of =200 - 80).

5. Frequently Asked Questions (FAQ)

Q1: Does Excel have a SUBTRACT function?

A1: No, Excel doesn’t include a dedicated SUBTRACT function. Use the minus sign (-) operator or combine the SUM function with negative values for multiple subtractions.

Q2: How do I subtract multiple cells from one cell in Excel?

A2: Use the formula =MinuendCell - SUM(SubtrahendRange). For example, =A1 - SUM(B1:D1) subtracts the total of B1, C1, and D1 from A1.

Q3: Can I subtract entire columns in Excel without typing formulas for each row?

A3: Yes! Enter the formula for the first row (e.g., =A2 - B2), then drag the fill handle (black cross) down the column to apply the formula to all rows automatically.

Q4: How do I subtract dates in Excel to get days between them?

A4: Subtract the earlier date from the later date using cell references: =EndDateCell - StartDateCell. For example, =B2 - A2 where A2 is 03/01/2025 and B2 is 03/10/2025 returns 9 days.

Q5: How to subtract a percentage from a number in Excel?

A5: Use the formula =OriginalValue * (1 - Percentage). For example, =200 * (1 - 0.2) subtracts 20% from 200, resulting in 160.

Q6: Why am I getting a #VALUE! error when subtracting in Excel?

A6: This error typically happens if you’re referencing cells with text (instead of numbers) or if your region’s list separator is set to the minus sign. Ensure all cells contain numeric values and adjust your list separator to a comma or semicolon.

Q7: How do I subtract a fixed number from an entire column in Excel?

A7: Use an absolute cell reference for the fixed number. For example, =A2 - $C$1 subtracts the value in C1 (fixed) from every cell in column A. The $ locks the cell reference so it doesn’t shift when copying the formula.

Q8: Can I subtract rows in Excel horizontally?

A8: Yes! Enter the formula in the first cell (e.g., =B1 - A1), then drag the fill handle to the right to subtract corresponding values across the row.

Q9: How to subtract text from text in Excel?

A9: Use the SUBSTITUTE and TRIM functions. For example, to remove the first name (in B2) from a full name (in A2), use =TRIM(SUBSTITUTE(A2, B2, "")).

Q10: How do I subtract months from a date in Excel?

A10: Use the EDATE function: =EDATE(StartDate, -Months). For example, =EDATE(A2, -4) subtracts 4 months from the date in A2.

Q11: What’s the difference between =A1 - B1 and =SUM(A1, -B1) in Excel?

A11: Both return the same result—they subtract B1 from A1. SUM(A1, -B1) is useful for combining subtraction with addition in complex formulas.

Q12: How to subtract blank cells without getting errors?

A12: Use the IFERROR function to handle blanks: =IFERROR(A2 - B2, 0). This returns 0 if either A2 or B2 is blank, instead of an error.

Q13: Can I subtract time in Excel?

A13: Yes! Enter time values in cells (e.g., A2 = 9:00 AM, B2 = 2:30 PM), then use =B2 - A2 to get the duration (5.5 hours). Format the result cell as “Time” to display it correctly.

Q14: How do I subtract two columns and get absolute values in Excel?

A14: Wrap your subtraction formula in the ABS function: =ABS(A2 - B2). This returns the positive difference, even if the result is negative.

Q15: How to subtract using array formulas in Excel?

A15: For large datasets, use an array formula to subtract entire ranges at once. Select the result range (e.g., C1:C10), enter =A1:A10 - B1:B10, then press Ctrl+Shift+Enter (Excel adds curly braces around the formula).

Q16: Why does Excel show a serial number instead of a date when subtracting dates?

A16: Excel stores dates as serial numbers. Format the result cell: Right-click > Format Cells > Category > Date, then select your preferred date format.

Q17: How to subtract in Excel Online?

Q19: How to subtract a range of cells from a single cell in Excel?

A19: Use =SingleCell - SUM(Range). For example, =A1 - SUM(B1:B5) subtracts the total of cells B1 to B5 from A1.

Q20: How do I fix subtraction formulas that aren’t updating?

A20: Check if Excel is in “Manual Calculation” mode. Go to File > Options > Formulas > Calculation options > Select “Automatic.” This ensures formulas update when cell values change.

Q21: How to subtract percentages between two numbers in Excel?

A21: Use the formula =((NewValue - OldValue)/OldValue)*100 to find the percentage difference. For example, =((150 - 200)/200)*100 returns -25%, meaning a 25% decrease.

Q22: Can I subtract in Excel using a shortcut?

A22: There’s no dedicated subtraction shortcut, but you can quickly enter formulas by clicking cells instead of typing references. For example, type =, click A2, type -, click B2, then press Enter.

Q23: How to subtract years from a date in Excel?

A23: Use the DATE function: =DATE(YEAR(A2) - Years, MONTH(A2), DAY(A2)). For example, =DATE(YEAR(A2) - 3, MONTH(A2), DAY(A2)) subtracts 3 years from the date in A2.

Q24: How do I subtract in Excel for Mac?

A24: The methods are identical to Windows—use the minus sign, cell references, and functions like SUM or DATEDIF. The fill handle and keyboard shortcuts (e.g., Ctrl+Enter for array formulas) work the same way.

Q25: Why is my Excel subtraction formula returning zero?

A25: This happens if the minuend and subtrahend are equal, or if the cells you’re referencing contain zero values. Double-check the cell values to ensure they’re correct.

Q26: How to subtract multiple ranges in Excel?

A26: Combine the SUM function for each range: =SUM(Range1) - SUM(Range2). For example, =SUM(A1:A5) - SUM(B1:B3) subtracts the total of B1-B3 from A1-A5.

Q27: How to subtract in Excel using Power Query?

A27: In Power Query, add a custom column with the formula [MinuendColumn] - [SubtrahendColumn]. This is useful for large datasets or automated data workflows.

Q28: Can I subtract negative numbers in Excel?

A28: Yes! Subtracting a negative number is the same as adding a positive number. For example, =10 - (-5) returns 15, and =A2 - (-B2) is equivalent to =A2 + B2.

Q29: How to subtract and round the result in Excel?

A29: Wrap your subtraction formula in the ROUND function: =ROUND(A2 - B2, 2) rounds the result to 2 decimal places. Adjust the second number for more or fewer decimals.

Q30: How do I subtract time across midnight in Excel?

A30: Use the formula =IF(B2 < A2, B2 + 1 - A2, B2 - A2). This accounts for times that cross midnight (e.g., A2 = 11:00 PM, B2 = 2:00 AM) and returns the correct duration (3 hours).

A31: The same techniques apply—use the minus sign for basic subtraction, cell references, and functions like DATEDIF or EDATE. Google Sheets supports all Excel subtraction methods.

Q32: How to subtract a cell value from all cells in a row?

A32: Use an absolute reference: =B1 - $A$1 (locks A1 as the subtrahend). Drag the fill handle to the right to apply the formula to the entire row.

Q33: How to subtract and count cells in Excel?

A33: Use =COUNTIFS(Range, ">"&Value) to count cells greater than a subtracted value. For example, =COUNTIFS(A1:A10, ">"&(B1 - 50)) counts cells in A1-A10 greater than B1 minus 50.

Q34: How to fix decimal subtraction errors in Excel?

A34: Use the ROUND function to avoid floating-point errors. For example, =ROUND(A2 - B2, 2) ensures the result has 2 decimal places, preventing unexpected values like 2.99999 instead of 3.00.

Q35: How to subtract in Excel using VBA?

A35: Use a simple VBA code: Range("C2").Value = Range("A2").Value - Range("B2").Value. For entire columns, loop through rows with a For-Next statement.
