Using Absolute Cell References in Excel

Introduction

• Discussing the use of absolute cell references for calculations in Excel.
• Example scenario: Multiplying data from two columns.

Basic Multiplication in Excel

• Start by selecting a cell to perform multiplication.
  • Example: Multiply cell B5 by C5.
• Use the fill handle (bottom right corner) to extend the formula across the column.

Problem with Relative References

• Introducing a static multiplier in cell E2 (e.g., 30).
• Formula: =B5*E2.
• Issue: Extending the formula does not work properly.
  • Formula changes to B6*E3, B7*E4, etc.
  • Cells E3, E4 are empty, leading to incorrect results.*

Solution: Absolute Cell References

• Convert relative reference to absolute cell reference.
• Method: Place a dollar sign ($) before both the column (E) and row number (2).
  • Formula: =B5*$E$2.*

Benefits of Absolute Cell References

• Locks the reference cell, preventing it from changing when extended.
• Useful for applying consistent operations across multiple cells.

Detailed Explanation

• Show formulas feature: Visualize changes (Formulas > Show Formulas).
• Illustrate cell locking by using dollar signs.
  • $E$2: Absolute reference, locked in both column and row.
  • $E2: Locks the column, allows row changes.
  • E$2: Locks the row, allows column changes.

Practical Applications

• Use absolute references to maintain a consistent reference point.
• Decide locking strategy based on whether the formula is extended across rows or columns.

• Recap of how to use dollar signs for absolute references in Excel.
• Importance of absolute references for extending formulas correctly.
