# How the Hours Cost Calculation Works

### Overview

The **Hours** cost calculation is a mix between the **Lump Sum** and the **Hours/Unit** calculation. This is great for when you want to charge a customer for a certain number of hours, regardless of the quantity / size of the project.

Like Lump Sum, *Hours* will ignore the quantity of the part itself. For this calculation, you will simply enter the total hours you want to charge, and the labor rate to use. Clear Estimates will calculate the cost of the part using the labor hours and labor rate!

*(Hours * Labor Rate) = Labor Cost*

### Where You Can Use It

The hours calculation option is available for your Labor costs only! That means you can set 3 Hours of labor at $50/hr, and the labor cost will be $150 regardless of if the part is 10 square feet or 500!

#### What costs can be hours?

### Examples

**Charge Hours for Labor**

Charging your customer a certain number of hours for labor is easy!

Just open the part using the blue "Edit" button. Then, make sure the "Labor Cost Calculation" is checked for your part.

Next, select the "**Hours**" calculation type for labor costs.

Last, simply enter the hours (how long it will take) and the labor rate!
