Next we're going to talk about charting cash flow, and how we put all of this together. So like I said, we're going to start talking about how we chart our cash flow for a project. There's a whole lot of things that can impact our revenues and our capital. Earned value that we have on a project. I believe you've learned about this with Dr. Aday. The retainage held by our client, the billings and the payment cycle. And we're going to walk through these one by one. So first, let's just come up with a sample project. I'll write the information up here, so we don't need to memorize it. So it's eight months, $12,000 contract. We, as the trade contractor, are going to spend $10,000. Meaning that our profit is going to be 20%. So what's our earned value? Our earned value is the value of the work completed to date and you've probably looked at this before, I'm pretty certain you have actually. So we're going to chart this and let's go ahead and create a chart real quick. So we know our total earned value is going to be $12,000 We know our project's going to last eight months. When you talked about earned value previously, I'm going to guess that you talked about the S curve. You'll see we have the months here, so here's time equals zero, and each hash represents the end of the month. So we have time equals eight months completed. Earned value we'd expect right to be about 12,000, the full value. And here, about midway, we'll pass that midway point and we're going to see this S-curve, right. It's an important curve, it's the trajectory we expect our project to take. So, we could trace this curve and find our total earned value at any point along this line. Now we know that our total expenses are about $10,000, right. We're going to see total expenses in the amount of $10,000 and it's going to happen in the same place. In month eight, total expenses should be $10,000. And for our sake, we're going to assume that we follow about the same path. So we're going to, see 20% difference between these two through the life of the project. So we'll just label these, expense, And earned value, just so we don't forget.
