A contingency, permit cost, fee, or other cost item can be added to your estimate in several ways, but the easiest is to use Adds and Cuts. With your estimate open, click on the Summary tab, and then click the Adds and Cuts button. The following window will open:

When the Adds/Cuts window opens, click the drop-down list at the Add button and select to add either an absolute value or a percent value. Enter a name and a value and Sigma makes the calculations.

Adding Absolute values is straight forward. The amounts (value) is simply added to the costs and is reflected in the total. The position of an absolute value in the hierarchy of the Adds/Cuts window has no effect on the final total amount. Its position influences the running total, but not the final total amount.

Adding percentage values is a different story. The position of the percentage value in the hierarchy controls which subtotal the percent acts upon. Additionally, percent values cam be indented or outdented by pressing Control and the left or right arrow. In the screen captures below, we’ve added percent 1 and percent 2, which is indented under percent 1 by default. As you can see in the image below, when percent 2 is indented, it is acting upon the total of the Sales Price and percent 1.

However, if Control / left arrow is used to outdent percent 2, it is acting upon the Sales price just as percent 1 is.

In this example, you can see the difference it makes if percent 1 is above or below absolute 2.
