Unit economics

Unit economics calculation: CAC, LTV, margin, payback period, break-even point and maximum affordable cost per lead. Find out whether your model works before you invest in traffic.

Overview

Find out whether your model can scale

Revenue growth doesn't always mean profit growth. If acquisition cost, margin and payback period aren't linked in one model, a bigger budget can just make you lose money faster. We define the decision boundaries: how much you can pay per customer, what sales volume you need and what to change before scaling.

In plain words

What it is and why it matters

What it is
We calculate what it costs to acquire one customer, how much they bring in and when the investment pays back. This shows whether you can increase your acquisition budget without growing losses.
Who it is for
An IT company that already has paying customers and revenue data and plans to increase its budget or compare products, segments and channels.
What you get
A model with documented data sources, customer cost and value, payback period, break-even point, three scenarios and the maximum affordable cost per customer and per lead (inquiry).
Where to start
Tell us which products or channels you need to compare and what revenue and cost data you already have. After an initial data review we confirm the scope and timeline.

Solution architecture

How we calculate unit economics using the 5D methodology

We start with the quality of the source data and finish with the conditions under which growth doesn't destroy profit and cash flow.

01

Discover

Check the data

We analyze revenue, direct and variable costs, acquisition channels, repeat purchases and retention.

02

Design

Build the model

We define the unit of calculation and link acquisition cost, customer value, margin and payback period.

03

Deploy

Run the scenarios

We build base, target and stress scenarios and test sensitivity to price, conversion and retention.

04

Drive

Set the thresholds

We set the maximum affordable cost per customer and per lead, the required sales volume and the payback period.

05

Dominate

Choose the action

We show what can be scaled, what to improve first and which data to collect regularly.

Unit economics and ROI

Where the calculation pays off

Unit economics keeps your budget from scaling a loss-making model. The team sees not just total revenue, but customer cost, margin and payback time by product and channel.

The effect comes when budget shifts to sustainable channels, price and margin are adjusted before growth, and decisions rely on acceptable thresholds rather than business-wide averages.

Comparison of approaches

Calculation or growth by gut feeling

The same revenue can hide either sustainable growth or mounting losses.

Limitations and risks

When the calculation is premature

Unit economics is useful once you have real sales data. Without it, precise formulas create false confidence.

The product is only at the idea stage

Without proven demand, you first need to test the value and willingness to pay.

Sales are few and far between

With so little data, you can't tell a pattern from a random result.

Revenue and costs are mixed together

If metrics can't be split by product or channel, you first need to set up proper accounting.

A good fit

When this service is a good fit

  • You have paying customers and revenue data
  • Acquisition costs are known or can be reconstructed
  • The team plans to increase the budget
  • You need to compare products, segments or channels

Not a fit

When to choose another approach

  • The product is at the idea stage
  • Sales are still few and far between
  • Revenue and costs can't be separated
  • Economics are already tracked regularly and the goal is to grow sales

Terms in plain words

Customer acquisition cost (CAC)
how much a company spends to win one customer
Customer lifetime value (LTV)
how much gross profit a customer brings over their entire lifetime
Margin
the share of revenue left after direct costs
Payback period
the time it takes to recover acquisition costs
Break-even point
the sales volume at which the product stops making a loss
Churn
The share of customers who stop paying within a period. Higher churn means each customer brings less and acquisition takes longer to pay back.
Stress scenario
A calculation under unfavorable conditions: lower prices, weaker conversion, faster churn. Shows whether the model survives a difficult period.
Cohort
A group of customers who joined in the same period. Cohort retention shows how many are still paying after one, three and six months.

Frequently asked questions

Unit economics: FAQ

Is there a universal LTV to CAC benchmark?

No. The ratio has to be assessed together with gross margin, payback period, churn and the cash cycle.

What if we don't have much data?

We use the verified part, record the assumptions explicitly and show which metrics you need to start collecting. If there aren't enough facts, we say so directly in the conclusions.

How is this different from a financial model and RevOps?

Unit economics looks at a single customer, order or product. A financial model shows the business as a whole. RevOps turns revenue and pipeline metrics into an ongoing management process.

What does the team get at the end?

A calculation model, a list of sources and assumptions, scenarios, decision thresholds and recommendations for further data collection.

How much does a unit economics calculation cost?

The cost depends on the number of products, segments and channels to compare and on the quality of the source data. We fix it after an initial data review, once it is clear how many metrics will have to be reconstructed manually.

How do you calculate unit economics for a subscription SaaS?

In a subscription model the unit is usually a customer or an account. We connect acquisition cost, monthly revenue, gross margin, churn and payback period. This shows how many months it takes a customer to pay back the investment and at what churn level the model stops working.

How long does a unit economics calculation take?

It depends on the number of products and channels and on how ready the data is. If revenue and costs have to be pulled from different systems, most of the time goes into verifying the source numbers. We give a realistic timeline after an initial data review.

What data do you need to calculate unit economics?

Revenue by customer or order, direct and variable costs, marketing and sales spend by channel, and data on repeat purchases, renewals and churn. For SaaS and apps, exports from billing, the CRM and product analytics are especially useful.

Can you calculate unit economics for a mobile app?

Yes. For an app we calculate the cost per install and per paying user, conversion to payment, cohort retention and revenue per user after app store fees. This shows which acquisition channels can be scaled and which are losing money.
