Customer lifetime value (LTV)
Customer lifetime value is the total gross profit you expect from a customer across the whole relationship. It is used mainly as a ratio against customer acquisition cost to decide how much you can afford to spend winning a customer, which means the assumptions behind it matter more than the number itself.
How it is calculated
A common form is average revenue per account, multiplied by gross margin, divided by churn rate. Using revenue rather than gross profit is the most frequent error and inflates the figure by whatever your cost of delivery is.
Why it is fragile
Dividing by churn assumes churn is constant and that customers behave like a single population. Early-stage businesses have too little history for a stable churn figure, so the resulting lifetime value is a projection built on a projection.
How to use it responsibly
Treat it as a segment-level planning tool rather than a per-customer fact, calculate it separately per segment because blended figures hide the mix, and always state the assumptions alongside the number.
What does a worked LTV calculation look like?
Say the average account pays Rs 5,000 a month, gross margin is 80%, and monthly churn is 2.5%. Monthly gross profit per account is Rs 4,000. Dividing by churn gives Rs 4,000 divided by 0.025, which is Rs 1,60,000. That is the lifetime value under the assumption that churn stays at 2.5% forever and every account behaves like the average.
Now halve the churn to 1.25% and the same formula gives Rs 3,20,000. A small change in the churn estimate doubles the answer, which is why LTV built on a few months of churn data should be treated as a range, not a figure. The free CAC and LTV calculator lets you try different assumptions.
Some teams cap the lifetime at a fixed horizon, such as three or five years, instead of dividing by churn. With the same inputs, a three-year cap gives Rs 4,000 times 36 months, or Rs 1,44,000, before any discounting. A capped figure is less sensitive to a churn estimate you do not trust yet, which makes it easier to defend in a planning meeting.
How does LTV connect to what you can spend on acquisition?
Through the LTV to CAC ratio and the payback period. If LTV is Rs 1,60,000 and it costs Rs 40,000 in sales and marketing to win an account, the ratio is 4 to 1. Payback is CAC divided by monthly gross profit: Rs 40,000 divided by Rs 4,000 is 10 months before the account has paid back what it cost to win.
Payback is often the more practical number for a small company, because cash runs out before a lifetime arrives. Customer acquisition cost explained covers how to calculate the CAC side honestly, including salaries and tools.
Why should LTV be calculated per segment?
Because segments differ on every input. Small accounts often pay less and churn faster; larger accounts pay more, churn less and cost more to win. A blended LTV mixes them into a number that describes nobody, and a blended LTV to CAC ratio can look healthy while one segment loses money on every customer.
Split at least by plan or company size, and by acquisition channel if you have enough customers in each. If outbound-sourced accounts show a higher LTV but also a higher CAC, the ratio for each channel is what decides where the next rupee goes.
What part of LTV can a CRM help measure?
The acquisition side. Autocloz reports pipeline, deal value and channel attribution, so you can see which sources produce the deals that close and at what size. Margin and churn data live in billing and finance systems, so LTV itself is calculated there. Sales metrics and KPIs to track lists the related measures.
How Autocloz handles it
Autocloz reports pipeline, deal value and channel attribution so you can see which sources produce the deals that close. Lifetime value itself depends on billing and margin data that lives in your finance system; the free CAC and LTV calculator does the arithmetic.
FAQ
How do you calculate LTV?
A common formula is average revenue per account multiplied by gross margin, divided by churn rate. Use gross profit rather than revenue — using revenue overstates the figure by your entire cost of delivery.
What is a good LTV to CAC ratio?
A ratio of roughly three to one is widely used as a planning benchmark, but it is a rule of thumb rather than a law, and it depends on payback period and how confident you are in the churn figure underneath the lifetime value.
