Pro Tip – Calculate Sales Conversion Rate & Lead Value

We often find oursellves explaining to prospects and clients about how “web design” (when done right) is actually more about “marketing” than design.

The problem is that many small business owners don’t know where to begin when it comes marketing their business and tracking their efforts. They shoot from the hip, trying different things, not ever knowing what the return on investment actually is.

As a business owner, you don’t also have to be a marketer, but understanding a few important metrics about your sales funnel can help you direct your efforts sensibly, without throwing your money away on advertising that doesn’t bring a return.

What is a Lead?

In marketing terms, a lead is any person or entity (as in a business) that is potentially interested in purchasing your product or service. Some leads are going to be better than others.

A “hot lead” might be more qualified (more ready to buy) than say a “cold lead” that needs more convincing before pulling the trigger. For this reason, a hot or warm lead would be understandably more valuable to you than a cold lead… But how valuable?

We’ll explore the value of a lead more in-depth in a bit, but first let’s talk about conversions.

What is a Conversion?

A conversion is any action that you define. It could be a purchase, an old fashioned phone call, contact form submission, newsletter signup, social share, a specified length of time a visitor spends on a web page, playing a video, a download, etc.

Many of the small businesses that I meet only have a gut-sense of where their new business comes from because they haven’t been tracking conversions.

Knowing your conversion rate(s) is a first step in understanding how your sales funnel is performing and what marketing avenues are giving the greatest return on investment (ROI).

Conversion Rate and How to Calculate It

Once you have defined what conversions you want to track, you can calculate the conversion rate. For the purposes of the following example, let’s call a conversion a sale.

Even if you’re still in the dark ages without a viable website, as long as you are tracking the number of leads you get and the number of resulting sales (conversions), you can calculate your conversion rate like so…

Conversion Rate = Total Number of Sales / Number of Leads * 100

Example: Let’s say you made 20 sales last year and you had 100 inquiries/ leads. Your sales to lead conversion rate would be 20%.

If you’re tracking conversions from website leads, your formula looks like so:

Conversion Rate = Total Number of Sales / Number of Unique Visitors * 100

Example: If you made 20 sales in a month and you had 2,000 unique visitors to your site, your conversion rate would be 1%.

What is The Value of a Lead?

The value of something is what it’s worth to you. If you sell lawn irrigation systems at an average price of $2,000 installed and you turn a lead into a sale, then that lead is worth $2,000 to you.

However, we know that not every lead you get will end in a sale. In reality you might only turn two out of 10 inquiries into a sale. That would make your conversion rate 20% (2/10 * 100 = 20).

That means you can expect to generate about $4,000 from your 10 leads (2 sales @ $2,000 ea). That’s because we know on average you are closing 2 out of 10 sales, a 20% conversion rate. This means that the value of one lead is actually $400 (4,000/10).

Here’s the formula:

Lead Value = Value of Sale / Number of Leads

The previous example is a bit simplistic and you can get much deeper with this stuff. As we discussed earlier, some leads will be more qualified than others and we will also want to look at what the actual profit is – not just the revenue. More on that in a minute.

Why The Value of a Lead Becomes Useful

When you know what the value of a lead is, you can determine how many leads you need each month to sustain your business and how much you should pay for advertising. This is true whether you are using pay-per-click (PPC) or any offline advertising, like mailers or print ads.

Conversions Needed = Desired Revenue / Lead Value

Example: Let’s say you need to generate $15,000 per month to float your irrigation business. Based on your conversion rate of 20% (2 sales / 10 leads x 100 = 20) from the previous example, you already know that each lead is worth about $400 (4,000/10).

This means, you would need about 37-38 leads per month (15,000 / 400 = 37.5) to make about 7-8 sales ($2,000 ea) and generate $15,000 in revenue.

(Note: This is a very simplistic example using revenue generated. A more accurate option would be to use the profit generated by sales and not just the revenue, but many businesses have difficulty defining this number so we use revenue as a guide.)

Example: If each sale of $2,000 actually costs you $1,000 to deliver, the profit on each sale is really $1,000. To get a return on your advertising spend, you’ll actually need to generate 75 leads to reach your $15,000 monthly goal.

The math:

1 sale = $1,000 profit

Conversion rate = 20% (2/10 * 100 = 20%)

Average lead Value = $200 ($2,000 /10 = $200)

Leads needed = 75 ($15,000 / $200 = 75)

Even if you use revenue instead of actual profit, as long as you are constantly tracking these metrics, you will be able to make much more informed decisions.

Understanding your sales funnel, can help you determine the number of leads you need to get each month, how much you can safely spend on advertising and what you can expect in return.

How to Leverage Lead Value to Your Advantage

In the business world things aren’t always so simple. Not all sales are going to be equal. Some sales will be a homerun and others won’t.

Also, the conversion rates are going to be different depending on the traffic source. You may find that leads generated by paid search convert better because you’ve been hyper-focused on your advertising, using keywords with extremely high commercial intent and/or targeting customers that are very local to you.

So with an average order value of $2,000 you might see something like this:


This shows that the value of a lead may be different depending on the lead source.

From this, you can see that a lead generated from your paid search campaign is worth more to you than a lead generated from organic search.

If you have Google analytics installed on your site (and you should) you can determine the average lead value and enter this into your analytics goal, then Google Analytics will do most of the hard work for you.

If you just stuff the average revenue value into the goal value, you’ll see highly inflated numbers that won’t make sense, as not every lead generated from the website will actually result in a sale.

Using a realistic lead value as your goal value will give you a clearer insight into how your website is performing.
