We can keep a **formula constant** with the **F4 key**. In this tutorial, we will learn the easy way of keeping the **value of a cell** constant.

*Figure 1 – How to keep value constant in formula*

**How to Keep a Cell Constant**

- We will use
**figure 2**to illustrate how we can keep a formula**constant**regardless of where we copy the formula.

*Figure 2 – How to keep a reference constant*

- When we press enter for the formula in figure 2, we will get the result. If we copy down the formula in
**Cell C9**, the cell reference changes to sum**Cell C5**and**Cell D5**

*Figure 3 – How to keep a value constant*

**How to Keep Cell Value Constant**** with the F4 key**

**Assuming we intend to sum the values in Column C while keeping the “value” in Column D as D4 in the formula, we will add the dollar sign before copying down the formula as shown in Figure 4. We can also press the F4 Key when we take our cursor to the positions before the Column Letter (D) and the Column Number (4).**

**Formula =SUM(C4,$D4)**

*Figure 4 – How to keep value constant formula*

**Note –** If we have a formula like **=SUM($C$4,$D$4)**, that will tell Excel to maintain the same cell reference (the formula), no matter the cell it is copied to.
