Cost an engaged lead off payroll and set the learning budget

1. The formula

Total payroll divided by total engaged leads is your cost per engaged lead.

That is the whole calculation. The point it makes is that a lead which cost you nothing in media still cost you something: you paid for it in payroll instead.

Input	What it is
Total payroll	What the team that produces the leads costs you over the period
Total engaged leads	The leads that team produced over the same period
Output	Cost per engaged lead

A variant you may run instead. Divide by qualified leads rather than all engaged leads, or by anything else you want to cost — the structure of the calculation does not change.

The one case where the formula is incomplete. For paid advertising you have to add the media spend to the payroll before you divide. Payroll alone gives a true cost per lead for outbound and for content.

2. The worked chain, and where its arithmetic disagrees with itself

The chain runs: payroll → cost per engaged lead → cost to win a customer → the ratio against the gross profit a customer produces over their lifetime. Worked through with the figures offered:

Step	Figure
Leads a setting team produced	1,000
Payroll behind them	$100,000, in a second reading only
Cost per engaged lead	$100
Engaged leads per customer	10 (one in ten converts)
Cost to win a customer	$1,000
Gross profit per customer, over their lifetime	$40,000; a second reading gives $4,000
Ratio of that lifetime profit to cost	Stated as 4:1

The payroll figure is missing where the example begins. The example says a setting team's payroll produced a thousand leads and that the cost per engaged lead was a hundred dollars, but the payroll number itself is not given there. A hundred dollars across a thousand leads implies a payroll of a hundred thousand dollars for the period. A second reading of the same chain states that payroll outright: a hundred thousand dollars over a thousand leads.

First disagreement — one hundred or two hundred. The cost per engaged lead is stated as one hundred dollars and then, one sentence later, used as two hundred dollars in the multiplication that produces the cost to win a customer. The product given is a thousand dollars. A hundred dollars times ten engaged leads is a thousand; two hundred times ten is two thousand. This page carries one hundred dollars, because it is both the figure stated first and the figure the product agrees with. The second reading of the chain uses a hundred dollars at each step and never two hundred. This page does not settle which reading is right. If two hundred is correct, every figure downstream of it doubles and the cost to win a customer is two thousand, not one thousand.

Second disagreement — four to one or forty to one. Forty thousand dollars of profit over a customer's lifetime, set against a thousand dollars of cost, is forty to one. The ratio stated is four to one. Four to one would require either a lifetime figure of four thousand dollars or a cost to win a customer of ten thousand. The second reading gives the first of those: four thousand dollars of lifetime gross profit against a thousand of cost, which is the four to one stated. On that reading the forty thousand is the figure in error. This page does not settle which reading is right. Taking four to one at face value understates the return in this example by a factor of ten; taking forty to one means the stated ratio is wrong and the figures above it are right.

What is not in dispute is the shape: payroll gives you a cost per lead, a conversion rate gives you a cost per customer, and the lifetime profit divided by that cost gives you the ratio you manage the business against.

3. A second worked figure, and the same problem

A second example is offered from a live operation, and its three numbers do not reconcile either. Every one of them is hedged where it is given — roughly, probably, about, and a warning alongside them that the figures are a little outdated — and every one of them is carried here.

Figure as stated	Value
Cost per engaged lead	roughly 3.33, stated as cents
Media-side payroll	probably $150,000 a month
Leads through the site	about 30,000 a month

A hundred and fifty thousand divided by thirty thousand is five dollars. Three dollars and thirty-three cents would need a payroll nearer a hundred thousand. And a cost of 3.33 cents per engaged lead is three orders of magnitude away from either. A second reading of the same operation gives a content team's payroll of about a hundred thousand dollars a month against about thirty thousand leads a month, and a cost of roughly $3.33 a lead, in dollars; those three agree with one another. This page does not settle which reading is right. What the stated inputs support, divided as §1 says to divide them, is five dollars per engaged lead. Carrying 3.33 instead means one of the inputs is wrong; carrying the divided figure means the stated unit cost is wrong.

The point the example is making survives all three readings intact: this operation ran no paid advertising at all, and its leads still cost real money, because the payroll behind them is real money.

4. What to do with the number once you have it

Benchmark people against the team, not against an absolute. Compare each person's cost per engaged lead against the team's benchmark. The expectation is that a new person raises the benchmark, and that over time the benchmark keeps rising, because everyone should be getting better.

Show everyone the scoreboard. Everybody on the team should know this calculation, because it is how they are being measured, and someone who knows how they are measured can win. Most people want to win, and shown the scoreboard will do what it takes to move it.

If you cannot calculate it, you cannot justify hiring. Without the number, bringing more people on becomes significantly harder to defend, because nothing connects the payroll to the return.

The failure of attention this guards against. An owner will agonize over a two-hundred-dollar monthly bill and hire three people at eighty thousand dollars each without blinking — a commitment of two hundred and forty thousand dollars a year, owed whatever happens, that never gets examined as a return on investment. The habit to replace it with is to think of everything as an allocation of resources and ask where the return is highest.

The arithmetic in that example holds: three people at eighty thousand each is two hundred and forty thousand. A figure of two hundred and fifty thousand is also given for it and corrected at once to two hundred and forty thousand; two hundred and forty thousand is the figure carried here.

5. The rule of thumb on a cost that is too high, and the band that contradicts itself

If your cost to win a customer runs more than three times your industry average, you likely have either a sales problem or an advertising problem. You find the industry average by looking it up for your category, at the level of "a fitness customer", "a software subscriber", "a small-business sale".

The band around the threshold is stated more than once, and the statements disagree.

Reading	What it says about being inside the 3× band
First	You might not have a problem at all
Second	You have a business model issue
Third	Good enough on cost; the work turns to raising what a customer is worth over their lifetime

Above the band, one statement of the third reading names a sales or an advertising problem; another sends the work to the advertising.

This page does not settle which reading is right. Reading it the first way, a cost inside the band needs no action and you go and do something else; reading it the second way, a cost inside the band means the model itself is wrong and the work is much larger than a sales or advertising fix.

Where the diagnosis goes when the cost is above the band — sorting an advertising problem from a sales problem — is SOP 196.

One thing the rule of thumb is explicitly for. So that you do not blame the people on the team for a problem in the business model that you built yourself.

6. The learning budget

A learning budget is money you decide in advance to spend on ideas you have given yourself complete permission to fail at. The reason to name it and ring-fence it is that without the permission you do not spend it, and without spending it you do not learn.

Both ways to set it are given.

Method	The figure
As a share of spend	Might be 5 percent or 10 percent of what you spend on advertising per month
As an absolute amount	A fixed sum per month you are willing to lose

In one example the absolute method was chosen over the percentage, and the sum chosen was ten thousand dollars a month. The condition that governs that number: it was set by an operation already making a great deal of money every month, by an owner whose spending habits, on the owner's own plain account, had not caught up with the size of the business. It is not a starting figure for a small operation. Set yours against your own spend.

What you should expect to get. Most times the ideas do nothing. Every once in a while one takes off. That is the whole distribution, stated plainly, and it is why the budget is defined as money you are willing to lose rather than money you expect to return.

Flag: how much of the spend goes to testing. This section puts the share at what might be 5 or 10 percent of monthly advertising spend, for ideas expected to fail. A second practice, from a paid-ads team: the split changes, and most recently about 70 percent of its ad budget goes to what already performs and 30 percent to fresh versions of proven ads or to brand-new ones. Its 30 percent includes variations of proven ads. How hook effort splits is on SOP 122. This page does not settle which reading is right.

6.1 The same idea outside paid advertising

The budget is not only for media spend. The same ten-percent-ish share is applied to other work:

• Content. Around a tenth of what you publish is given over to ideas that are simply strange. One operation runs this as dedicated days — one day a month, or two days a month, with no meetings, where everyone is required to put together one or two pieces built on an odd idea. Some of the best ideas come out of those days.
• Outreach. Change the script or the offer for one person's work, one day a week or one day every two weeks, just to see.

A note on the share. The outreach version runs one day a week or one day every two weeks, and both are then called roughly ten percent. Against a five-day week, one day every two weeks is ten percent and one day a week is twenty. A second reading gives a range: 10 to 20 percent of effort on new, untried tools, where trying a new tool on one day of a five-day calling week is the example. This page does not settle which reading is right. The ten percent figure fits the every-two-weeks version only.

Why the balance is worth keeping, and it is given as two reasons. You stay ahead, because you keep innovating. And you do not burn out, because sometimes repetitive work you already know works gets boring.

6.2 The growth attributed to it

The operation that adopted a learning budget reports its monthly revenue climbing afterwards: modest steps for several months, then faster ones, then a final figure many times the first. Carry it with its conditions or not at all — the final figure is a later and larger company than the one at the start of the series; and the whole sequence is offered as a story about permission to fail, not as a forecast. This page gives no figure for the return a learning budget produces.

7. What this page does not decide for you

These are gaps in the procedure, not omissions from this page.

• Over what period to run the division. Monthly, quarterly or annual payroll — no period is specified.
• Whose payroll counts. Whether managers, part-timers or shared staff belong in the numerator is not stated.
• What a good cost per engaged lead is. Only the three-times-industry-average rule of thumb on the customer cost is given.
• How far above the benchmark a new person has to land, and by when.
• What to do when the ratio is below the level you want. Improving a ratio is on SOP 47 for affiliates and SOP 196 for the general case.
• Which way of setting a learning budget to prefer, other than by example.

9. What this page does not cover

Sorting a too-high cost into an advertising problem or a sales problem is SOP 196. Training the people whose payroll this page divides is SOP 43, and deciding whether to hire them or buy them ready-made is SOP 44. The ratio calculation for affiliates, which uses the same shape with different inputs, is SOP 47. The daily volume that produces the leads in the denominator is SOP 52.

Salary bands and compensation design are not covered on this page.
