Cost per lead calculator for marketing agencies

Most marketing agencies pitch "better leads, lower cost" without ever putting the prospect's own numbers on the table. A cost-per-lead calculator does that in one step: they type in what they're spending and how many leads it brings, and see their current cost per lead before you say a word about your service.

1. Ask for the two numbers that make the cost real

A prospect running ads almost always knows their monthly spend and roughly how many leads it brings in, even if nobody has divided one by the other. That's the whole calculator: monthly ad spend and leads per month in, cost per lead out.

2. Compare "what they pay now" to "what they'd pay with you"

The cost savings calculator template already compares two numbers and shows the gap. Set "current cost" to their current cost per lead (spend divided by leads) and "our price" to the cost per lead your service typically delivers — the saving is the case for switching, in their own currency, per lead.

3. Show the monthly total, not just the per-lead number

A euro or two of saving per lead sounds small; the same saving multiplied by their monthly lead volume usually isn't. Add a line under the result that multiplies the per-lead saving by their current leads-per-month, so the number that sticks is the one that justifies a new agency relationship.

4. The lead is a free lead-cost audit, not a sales call

Once a prospect has seen their own cost per lead, ask for a name, email and company with: "Want a free audit of where your ad spend is leaking?" That's a far warmer ask than "book a call", because they've already seen the problem is real and priced in euros before you spoke to them.

5. Start from the template

Open the cost savings calculator template, relabel the fields to "monthly ad spend" and "leads per month" (or pre-divide them into "current cost per lead" and "cost per lead with us" if you'd rather keep the formula simple), publish, and paste the one-line embed snippet into your site.
