Cost per lead hides the real cost
A $30 lead sounds cheap until a fifth of them qualify and you close one in four of those. That is a $600 customer, and it is the only figure worth comparing against what a customer is worth to you.
Free tool
Work out what hitting your customer target really costs.
Most lead reporting stops at cost per lead. This carries it through qualification and close to the number that matters: what a customer costs, and whether that is less than they are worth.
-
What it is
A calculator that works backwards from the customers you want to the leads, visitors and spend it takes to get them.
-
What it tells you
Monthly spend to hit the target, cost per qualified lead, cost per customer, the profit ratio, and the most you can pay per lead.
-
What you need
Customers wanted per month, qualification rate, close rate, cost per lead, profit per customer and visitor to lead rate.
-
What to do next
If the ratio is thin, fix the qualification rate before buying more leads. If it is comfortable, send us the account and we will check the lead cost holds at volume.
What it takes
Monthly spend to hit that target $0
Qualified leads needed 0
Total leads needed 0
Visitors needed 0
Cost per qualified lead $0
Cost per customer $0
Profit for every $1 spent winning a customer 0:1
Monthly gross profit after that spend $0
Most you can pay per lead and break even $0
How this is calculated
Working backwards from the target. Qualified leads equals customers divided by close rate. Total leads equals qualified leads divided by qualification rate. Visitors equals leads divided by the visitor to lead rate. Spend equals leads times cost per lead.
The most you can pay per lead is gross profit per customer multiplied by the close rate and the qualification rate. Past that, every customer costs more than they bring in.
What the result means
Start from the target, not the budget.
It turns a goal into a traffic number
Ten customers a month becomes a count of qualified leads, then total leads, then visitors. When you can see the visitor figure, you can tell in seconds whether your market is big enough to supply it.
It gives you a bidding ceiling
The last row is the most you can pay for a lead and still break even. Take that number into any conversation about buying leads and the negotiation is already over.
How realistic is the result?
This is an estimate. It assumes cost per lead holds as volume rises, which it rarely does perfectly, and that your close rate is a real twelve-month average.
What moves the real number
- Lead quality and qualification rate
- Sales follow-up speed
- Close rate
- Cost per lead in your market
- Offer and pricing
- Visitor to lead rate on the site
Where the sum flatters itself
- A qualify rate nobody measures. If leads are not scored anywhere, this input is a guess, and it is the one the answer moves on most.
- Cost per lead held flat as volume rises. The cheapest leads come first. Doubling the target rarely doubles the spend, it does worse.
- Sales capacity left out. Leads you do not call within the hour convert far below the rate you entered, and the model assumes every one gets worked.
- Revenue in the profit box. Gross profit per customer is the honest input, after delivery and after refunds.
- One blended conversion rate across every source. Referral traffic and cold traffic behave nothing alike, and averaging them hides the weak half.
Reading the result
Four things to do with the number.
Look at the visitors line first
It is the reality check. If the plan needs more monthly visitors than your whole category searches for, the target is not a budget problem and no channel will fix it. Lower the target or widen the offer.
Check the ratio, not the spend
Profit against what you spend to win a customer is the row that decides whether this is a business or a treadmill. Under two to one, a bad month hurts. Under one to one, growth is costing you money on every sale.
Improve the qualify rate before the lead price
Raising the share of leads that qualify costs nothing but better targeting and a harder form. It moves the spend figure further than a discount on the cost per lead ever will.
Take the ceiling into the negotiation
You now know the most you can pay for a lead. Anyone selling above that number is selling you a loss, however good the pitch is, and you can say so with a figure rather than a feeling.

Questions
What people ask before and after using it.
01 What is the lead generation calculator for?
Working out what it takes to hit a customer target. You enter the customers you want each month, the share of leads that qualify and the share of qualified leads you close. You add your cost per lead, your gross profit per customer and your visitor to lead rate. It works backwards to the qualified leads, total leads, visitors and spend required. It also shows what a customer costs and the most you can pay per lead before you lose money.
02 Why does it ask for a qualification rate?
Because raw leads and leads worth calling are different numbers, and the gap between them is where many lead generation budgets quietly disappear. An agency reporting cost per lead while half of those leads never qualify is reporting a number that flatters everyone and helps nobody. The calculator carries the cost through qualification and close, so what you see is the cost of a customer.
03 What counts as a qualified lead?
Whatever you and your sales team agree it means, written down before you measure it. A useful definition covers three things: the work is something you would take, the budget is plausible, and the person can make or influence the decision. Without that definition, lead quality is an argument rather than a metric, and the qualification rate you type in is a guess.
04 My close rate changes month to month, so what do I enter?
Use a twelve month average rather than last month. Monthly close rate on low volume swings wildly for reasons that have nothing to do with marketing. Building a plan on one good month is how budgets get set too high, and building it on one bad month is how a working channel gets cut. If you have less than a year of data, use what you have and say so.
05 Where do I find my cost per lead?
Divide what you spent on a channel in a month by the leads it produced in the same month. Your ads account reports cost per conversion, which is the same thing if conversions are set up to count leads. If you buy leads from a vendor, use the price per lead they charge. Do not include agency fees here unless you want them inside the answer, and then include them every time.
06 What is a good cost per customer?
There is no universal figure, and anyone quoting one is guessing. The only meaningful test is the ratio between what a customer costs to win and what they are worth over the relationship. The calculator shows that ratio as profit for every dollar spent. The verdict on the page treats three to one as the point where the sum becomes comfortable, and below that a rise in click cost can tip it into loss.
07 What moves the real number most?
The qualification rate, because it multiplies through everything below it. Then the close rate, which lives in your sales process rather than your marketing. Cost per lead depends on your industry and how competitive the auction is. The visitor to lead rate depends on your offer and your landing page. Speed matters too, because leads that are not called quickly convert well below the rate you entered.
08 Why does it show visitors needed?
Because it is the reality check on the target. Ten customers a month becomes a count of qualified leads, then total leads, then the visitors it takes to produce them. If that visitor figure is larger than your whole category searches for, the target is out of reach for any channel and no budget fixes it. Lower the target or widen the offer before you spend anything.
09 What should I do with the result?
Look at the visitors line first. Then look at the ratio rather than the spend, because the ratio decides whether this is a business or a treadmill. Work on the qualification rate before you negotiate the lead price, because better targeting and a harder form cost nothing. Take the most you can pay per lead into any conversation about buying leads. Anyone selling above it is selling you a loss.
10 Does this replace the free review?
No. The calculator works on the numbers you believe. The review looks at your real numbers in your accounts and tells you which of the inputs is the one holding you back. That is a different question and it needs a person to look. If the ratio here is thin, the review is where you find out whether the fix is the form, the targeting or the sales follow up.
11 Is what I type kept anywhere?
No. The calculator runs in your browser and nothing is sent to a server or saved. No contact record is created by using it, and closing the tab clears the numbers. The only form on this page that keeps anything is the review request, and only if you fill it in and send it.
12 What are the common mistakes with this calculator?
A qualification rate nobody measures, so the input the answer moves on most is a guess. Cost per lead held flat as volume rises, when the cheapest leads come first and doubling the target does worse than double the spend. Sales capacity left out, so every lead is assumed to get worked. Revenue in the profit box. And one blended conversion rate across referral and cold traffic, which hides the weak half.
