Whoever can spend more to attract a customer almost always wins over the long run.
The key point is that they can afford it. Not “burning the budget,” but understanding the numbers and knowing that every marketing hryvnia invested will come back with profit.
Most businesses try, at any cost, to reduce customer acquisition expenses: traffic, marketing, development. They set this as the main goal for specialists in contextual advertising and targeting. As a result, the ads seem cheaper, but at the same time traffic volume drops, and growth stops.
Scaling under such conditions is difficult, and “capturing the market” is practically impossible.
You need a business model in which you can consciously spend more on acquiring customers than your competitors—and still remain in the black. This is exactly the question of unit economics.
LTV, CAC, cash flow, and payback period—plainly explained
The main numbers you should rely on:
LTV (Lifetime Value)
How much money one customer brings you over the entire time they stay with you.
Very simplified:
LTV = average check × number of purchases over the customer’s “lifetime”
Better to calculate not only revenue, but what remains after cost of goods sold—margin. But even a simple calculation makes it clear: a customer — is not one sale, but the sum of all their purchases.
CAC (Customer Acquisition Cost)
How much one new customer actually costs you.
CAC = all marketing and acquisition expenses / number of new customers
This includes:
- advertising (context, targeting, bloggers, banners, etc.),
- production of creatives,
- services of agencies and freelancers,
- the share of salaries of those who handle acquisition.
LTV/CAC ratio
A benchmark that’s convenient to keep in mind:
If LTV/CAC ≈ 3:1, then it’s usually a “healthy” state.
Example:
A customer brings you 90 conventional units in total (LTV). Then:
- it’s reasonable to spend up to 30 conventional units to acquire one customer,
- that’s about the same 33% of LTV that people often talk about.
Not as a strict rule, but as a starting point:
3 parts of customer income:
1 part—for acquiring them,
2 parts—for cost of goods sold, operating expenses, and profit.
Payback period
How long it takes for the money invested in acquiring a customer to come back to you from their purchases.
It’s important not only “how much you earn,” but also when exactly that money returns. The longer the timeframe, the more risks there are and the harder it is to sustain growth with your own funds.
Growth point #1—everything that increases LTV
If we say it very simply:
the more money a customer brings you during the time you work with them, the more you can afford to spend on acquiring them.
Main directions for increasing LTV:
Increase the average check
- bundles, sets, packages;
- tariffs “standard / pro / premium”;
- logical upgrades instead of discounts.
Keep the customer longer
- loyalty programs and bonuses for repeat purchases;
- subscriptions and service plans;
- regular useful touchpoints: newsletters, reminders, personalized offers.
Upsells
- related products and services;
- upsell: “take a little more expensive, but it’s more beneficial in terms of what’s included”;
- cross-sell: “for this product, people usually also buy this.”
Market leaders spend up to 80% of their efforts specifically on increasing LTV, not on trying to make the click a bit cheaper.
Where entrepreneurs most often make mistakes
They treat marketing as an expense, not an investment
At the level of decisions, it looks like this:
- “Profit has dipped → cut advertising” instead of “let’s figure out the customer economics and the funnel.”
- With this approach, the business keeps getting tugged around, but doesn’t grow.
Focus only on lowering CAC
About 80% of entrepreneurs:
- set a goal for marketers: “make the click/lead/sale cheaper”;
- pressure on price and KPIs, completely ignoring what happens next with the customer.
As a result:
- the cost of an application may indeed drop,
- but along with it traffic volumes fall, “fat” segments get cut,
- the business hits a ceiling for growth.
Ignoring the entire funnel as a whole
From bottom to top, the funnel looks like this:
- click → application → sale → upsells → repeat purchases.
Often KPIs are set only for the first steps:
- cost per click,
- cost per application,
- cost of the first sale.
And everything that comes after (upsells, retention, repeat purchases) falls outside the scope.
Then the question arises: why, with “good” ad metrics, the business still earns too little.
How to set KPIs correctly for marketers and targeting specialists
When setting KPIs, you need to account for the entire chain, not only the first sale:
- customer acquisition cost (CAC);
- average check;
- purchase frequency;
- the share of customers who buy again or switch to more expensive products;
- final LTV by segments.
The advertising specialist’s task should not sound like this:
“Make the click/lead/sale cheaper”
but like this:
“Bring us customers with such-and-such cost constraints, so that as a result the LTV economics converges.”
This changes the approach from “squeezing ads to be cheaper” to “finding growth points in the model.”
Other people’s cases ≠ your growth points
Other people’s cases are not a magic button. What worked for someone doesn’t necessarily work for you in the same way.
The reasons are obvious:
- different product and value,
- different audience,
- different pricing and margin,
- different brand and level of trust,
- different customer “lifetime” duration.
You should treat someone else’s case as a reason to form a hypothesis, not a ready-made solution:
- Take the idea.
- Embed it into your numbers: how it will affect LTV and payback.
- Test it with a small budget.
- Leave only what truly improves your unit economics.
Mathematical modeling and strategic planning
Advertising is only one of the marketing tools.
The main growth tool is a simple but honest financial model.
What it should include at minimum:
- how much traffic costs (by channels);
- what conversions happen at each step of the funnel;
- how much the customer brings over time;
- what your margin is;
- how much you can afford to spend on acquisition while staying profitable;
- within what timeframe the investments pay back.
Then any decision—“raise bids in the auction,” “add a new channel,” “launch a new offer”—is checked not based on intuition, but through this model.
A strong product + strong distribution + clear unit economics = the same kind of business that can afford to spend more on customer acquisition than others and thereby win the market.
