Absolute vs. Relative References

When writing formulas in Excel, it's important to understand the difference between absolute and relative references. A relative reference is a reference to a cell based on its position relative to the current cell. For example, if you write a formula in cell B2 that refers to cell A1, the reference will be relative, meaning that if you copy the formula to cell B3, the reference will automatically update to refer to cell A2.

An absolute reference, on the other hand, is a reference to a specific cell that does not change when the formula is copied to another cell. To create an absolute reference, add a dollar sign ($) before the column letter and row number of the cell reference. For example, to create an absolute reference to cell A1, write "$A$1" in the formula.

By using a combination of basic formulas and common functions, and understanding the difference between absolute and relative references, you can perform a wide range of calculations in Excel.

Advanced Column Calculations
