When planning a B-to-B lead generation program, you need to deliver leads to your sales team at an affordable price. A neat way to determine in advance how much you can spend on a lead is to calculate the allowable cost per lead for your campaign. This number can then be used as a benchmark for evaluating campaign investments, and deciding which ones are likely to work. If a campaign is looking like it’s not affordable, then you’ll want to make some tweaks, like find a stronger offer, or narrow your targeting.
Begin by calculating your cost per inquiry. Assemble the total direct campaign costs, including all fixed and variable costs that can be directly attributed to the campaign. Include creative and pre-production work, cost of developing and producing content, and the normal variable costs of campaign development and execution. Divide this amount by the number of expected campaign responses, and voila! There’s your cost per inquiry.
Then, estimate the costs associated with qualifying a lead. Don’t try to determine this number on a per campaign basis — it’s too hard. Instead, calculate an average qualification cost for inquiries over a set period, such as a year. Gather up all your inquiry-handling costs, including the direct headcount involved in inquiry capture, fulfillment, qualification, and nurturing. If your back-end processes are outsourced, gathering the data is as simple as adding up the bills. After you have a number for the year, divide it by the number of inquiries handled in the year. This number will serve as your average cost to qualify an inquiry.
Finally, go talk to your counterparts in finance and sales to gather several data points. You need the average order size, namely, the total revenue divided by the total number of orders. (If this number swings wildly, do the calculation by product category.) You need the margin (or its opposite, the cost of goods sold) and the direct sales expense per order, calculated by the total sales expense divided by the total number of orders.
