How to Keep One Cell Constant in Excel: A Simple GuideUpdated 22 days ago
To keep one cell constant in Excel while copying a formula, use absolute referencing by adding a dollar sign ($) before the column and row in the cell reference. For example, if you want to keep cell A1 constant, write $A$1 in your formula.
Key Highlights: Keep One Cell Constant in Excel
- Absolute References: Use the `$` sign to lock both the column and row of a cell. For example, `=$A$1` ensures that the reference to cell A1 stays constant, even when copied to other cells.
- How to Apply Absolute Reference: Type your formula as usual but add `$` before the column and row (e.g., `=$A$1`). Use the F4 key to quickly toggle between reference types (relative, absolute, mixed).
- Examples: Formula for fixed value: `=$A$1 B1` will keep `A1` constant, even when you drag the formula across other cells.
- Date and Duration Calculation: Use `=$A$1 + B1` to keep the start date fixed while changing durations in the formula.
- Why Use Absolute References: Prevent errors when copying formulas across cells. Simplifies repetitive calculations and ensures consistency for fixed values or parameters.
- Types of References: Absolute Reference (`$A$1`): Locks both column and row. Mixed Reference (`A$1` or `$A1`): Locks either the column or the row.
Mastering absolute references will improve the accuracy and efficiency of your Excel formulas, particularly when working with constant values.
