Lead Value Calculator
What a lead is worth from the close rate, margin and repeat purchases, which is the only defensible ceiling on what a lead may cost.
Close rate 8.5%
Deal value $4,200.00
Gross margin 64%, so $2,688.00 a deal
Purchases a customer 2.40, so $6,451.20 over a lifetime
What a lead is worth
on the first deal $228.4800
over the lifetime $548.3520
after the sales cost $516.0520
sales cost a deal $380.00, which is $32.3000 a lead
What a lead may cost
break even $516.0520
at a 3:1 return $172.0173
at a 5:1 return $103.2104
which one depends on how much of the margin you are willing to spend on growth
Against what you pay now
cost per lead $95.00
value of a lead $516.0520

verdict comfortable: the leads are worth several times what they cost
cost per acquisition $1,117.65, which is the cost per lead over the close rate
With 420 leads
deals expected 35.7
revenue $359,856.00
gross profit $230,307.84
cost of the leads $39,900.00

If the close rate moves
4.25% $258.0260 a lead

12.75% $774.0780 a lead
17% $1,032.1040 a lead
A lead is worth $516.0520 here: the close rate times the gross margin
over the customer lifetime, less the cost of the selling. That is the
ceiling on what one may cost, and it is the number an advertising budget
should be built from rather than a share of revenue.
Lead value scales with the close rate, so it is the input worth
measuring rather than estimating. Halving the close rate halves the
value of every lead and therefore the most you can pay for one, which is
printed above.
Using the lifetime rather than the first deal raises the value from
$228.4800 to $548.3520. That is legitimate and it is a loan against the
future: the cash comes later, so the business has to be able to fund the
gap.
"What counts as a lead" is not an arithmetic question. A form fill, a
trial signup and a conference conversation have very different close
rates, so one blended lead value averages across categories that should
be priced separately, and the blended figure will be wrong for all of
them.
A 3:1 return on lead cost is a common target and it is a convention, not
a rule. It exists to leave room for the sales cost, the overhead and the
leads that were never real, and where those are measured explicitly the
ratio can be lower.
Cost per acquisition is the cost per lead divided by the close rate, so
improving the close rate is the same thing as reducing the cost per
acquisition. Sales and marketing usually own those two numbers
separately, which is why they are rarely optimised together.
Lead scoring changes the arithmetic rather than the conclusion. Scoring
splits the leads into groups with different close rates, each with its
own value and therefore its own affordable cost, which is how a channel
that looks unaffordable on average can be profitable for the top slice.

A lead is worth the close rate times the gross margin. On the figures below that is $516, which is the ceiling on what one may cost, and most advertising budgets are set without ever calculating it.
The refinements that matter are the lifetime rather than the first order, because a customer who buys again is worth more than one deal, and the sales cost, because a lead that needs three calls consumes margin before it produces any.
The part nobody can calculate for you is what counts as a lead. A form fill, a trial signup and a conversation at a conference have wildly different close rates, so a single blended lead value averages across categories that should be priced separately, and it will be wrong for all of them.
How to use
- Put in the close rate. If you do not know it, measuring it comes before any budget decision.
- Put in the deal value, the margin and how many times a customer buys.
- Add what you pay for a lead now to see the return.

Pitfalls
The close rate is the whole calculation. Everything else is arithmetic on it. A borrowed industry figure produces a lead value about somebody else’s business.
The lifetime figure is a loan against the future. Using repeat purchases is legitimate and correct, and the cash arrives later than the advertising invoice. A business that cannot fund the gap should budget on the first order.
Count the sales cost. Commission, demo time and the calls it took all come out of the same margin, and leaving them out overstates what a lead can afford to cost by exactly that amount.
A blended lead value hides the useful distinction. Score or segment the leads, and each group gets its own value and its own affordable cost. That is how a channel that looks unaffordable on average turns out to be profitable for the top slice.
Cost per acquisition is cost per lead over the close rate. So improving the close rate reduces the acquisition cost by the same proportion, and sales and marketing usually own those two numbers separately, which is why they are rarely worked on together.
3:1 is a convention, not a rule. It exists to leave room for the sales cost, the overhead and the leads that were never real. Where those are measured explicitly, a lower ratio is defensible.
A lead that is not contacted has no value at all. Response time dominates close rate in most studies, and a lead value calculated from a pipeline where half the leads were never called is measuring the follow-up, not the source.

Arithmetic in the browser: nothing is uploaded and nothing is stored.
The value is the close rate times the gross margin per deal, multiplied by purchases over a lifetime where that is given, less the sales cost per deal weighted by the close rate. Each step is printed so the figure can be argued with rather than accepted.
The sensitivity table shows the lead value at half, current, 1.5 times and double the close rate, which is the range within which most estimates are actually wrong.
Cost per acquisition is derived as the cost per lead divided by the close rate, which is the identity worth carrying: the two metrics are the same statement about the same funnel.
