Cost per lead calculator

Ad spend is what the campaign cost over the period, in one currency.

Leads is the count of whatever your business has agreed a lead is. That definition is the most consequential input on this page and the calculator cannot check it: a submitted form, a booked call, a downloaded guide and an address typed into a chat widget are different commitments, and a campaign that quietly starts counting a lighter one reports a cost per lead that fell while nothing improved.

Qualified leads is optional and is the count that survived whatever check the business applies — answered the phone, met the criteria, held the meeting, passed the scoring rule. Use the earliest checkpoint that is recorded reliably rather than the most rigorous one that is recorded late.

A cost per lead can be lowered by making leads easier to produce, and making leads easier to produce usually makes them worse.

Removing fields from a form raises volume and lowers cost, and it removes exactly the information that qualification depends on. Offering something everybody wants — a voucher, a free guide, a prize — raises volume and attracts people interested in the thing rather than the business. Widening the audience raises volume by including people who were never going to buy. Every one of those improves the headline figure and can raise the cost of a customer.

That is the trap the second output exists for. At 9,000 of spend and 300 leads the cost per lead is 30. If 90 of them qualify, the business is actually paying 100 for each lead it can use. A campaign at 45 a lead with a seventy per cent qualification rate is paying about 64, and on the headline it looks a third more expensive.

Ranking campaigns on the headline figure therefore moves budget toward whichever one produces the most easily generated leads. The effect is gradual, it is invisible in the metric being optimised, and it is one of the most reliable ways for a lead-generation account to get worse while its dashboard improves.

The rate between the two costs says where the problem is, and it separates three causes that look identical from the media side.

A rate that is low across every campaign and every source usually means the offer is attracting the wrong people. What was promised in exchange for the details is drawing an audience with no purchasing intent.

A rate that varies sharply by campaign or audience is a targeting result, and it is the most directly actionable version: the campaigns with poor rates are reaching people the business cannot serve, and excluding them raises the average without raising the bid.

A rate that fell suddenly with no change in the media is usually a form change, a tracking change or a new source being counted — a plumbing event rather than a performance one.

The rate is also the cheapest thing on this page to improve, because most of its levers are free. A single qualifying question on the form, a follow-up that reaches somebody within the hour rather than the week, and an offer written for buyers rather than browsers each move it without buying anything, and each one lowers the cost of a usable lead by exactly the proportion it raises the rate.

This page says what leads cost. It says nothing about what they are worth, and the second question is the one that decides whether any of these numbers are acceptable.

A lead is worth the gross profit of a deal multiplied by the share of leads that become one. A business closing one lead in five on a deal leaving 1,000 of gross profit can pay up to 200 a lead before it stops making money; a business closing one in fifty on a deal leaving 300 can pay 6. Both look at the same auction and neither has anything to learn from the other's benchmark.

That ceiling is the number to bid against, and it is the reason this page refuses to offer a target figure. Any published cost per lead describes a business whose close rate and deal size you do not know.

Work the rate before the cost. A campaign that doubles its qualification rate halves its cost per qualified lead without buying a single additional lead, and the levers are usually outside the ad account: a form that asks one qualifying question, an offer that speaks to buyers rather than browsers, a landing page that states the price range, a follow-up that reaches people while they still remember filling in the form.

Then exclude. Placements, audiences, keywords and regions that have produced leads and no qualified ones are carrying spend that is worse than wasted, because unqualified leads also consume the sales team's time.

Then the media. Better creative and a better-matched audience lower both costs at once, and bidding harder lowers neither — it buys the same leads at a higher price and reports the increase as a performance problem.
