Calculate Member LTV in Seconds
This free membership value calculator helps you calculate member LTV in seconds: see what an average member is really worth across their whole lifetime — subscription plus ancillary spend — and whether your acquisition costs stack up. Adjust the sliders to model your own organisation.

The Result

£1,320
Gross lifetime value per member
Strong
Above 5:1 — you can likely afford to acquire faster and still profit.
Cumulative revenue per member over 6 years
Of each member’s £220 annual value, 18% comes from ancillary spend — revenue you only capture if members stay engaged.
At 8.8:1 you are at or above the 3:1 ratio most membership bodies aim for.

How to Calculate Member LTV
Membership lifetime value (LTV) is the single most useful number for any membership organisation — the clearest measure of true membership value.
To calculate member LTV you multiply what an average member is worth each year by how long they stay; this membership value calculator does that maths for you.
It tells you how much revenue an average member generates across the entire time they stay — and it reframes every marketing decision.
Once you know a member is worth, say, £1,800 over their lifetime, spending £150 to recruit one stops looking like a cost and starts looking like an investment.
The formula to calculate member LTV is deliberately simple.
Take the annual subscription fee, add the average ancillary spend a member makes each year — event tickets, training, certifications, merchandise — and multiply by the average number of years a member stays.
Step 01
Annual value
Annual subscription + annual ancillary spend.
Step 02
× Average tenure
Years a member stays — 1 ÷ churn rate.
Step 03
− Acquisition cost
Gross lifetime value becomes net lifetime value.
Step 04
÷ Acquisition cost
Gross LTV over acquisition cost: the LTV:CAC health check.
03/ tenure and the ratio
Tenure is the inverse of churn.
That average tenure is the inverse of your churn rate, so a 12.5% annual churn rate implies an average membership length of eight years; the 2026 Membership Marketing Benchmarking Report puts the sector median renewal rate at 82%.
Subtract the cost to acquire a member and you have net lifetime value.
Divide gross lifetime value by acquisition cost and you get the LTV-to-acquisition ratio, a quick health check that membership specialists put at a minimum of 3:1 — GlueUp’s published guidance rather than a research finding.
Below that, acquisition is eating too much of each member’s value; comfortably above it, you can usually afford to grow faster.
Needs work

04/ ancillary spend
The figure most organisations underestimate.
The figure most organisations underestimate is ancillary spend.
For professional bodies and trade associations especially, what members pay for courses, accreditation and events over a decade often rivals the subscription itself — and all of it depends on members staying engaged.
That is why lifetime value is really a retention and engagement story as much as an acquisition one.

05/ a worked example
These are not abstract figures.
These are not abstract figures.
The membership sector’s most-cited worked example, from Marketing General’s Tony Rossell, takes an average member paying roughly $175 in dues at an 80% renewal rate — a five-year tenure — plus about $50 a year in non-dues spend, for a lifetime value near $1,125 against an average acquisition cost of just $24.
That same study found per-member ancillary spend sits at roughly a fifth of total member value, which is why we set this tool’s ancillary default conservatively rather than at the much larger organisation-level non-dues share of 40–60%.
You can pressure-test the other side of the equation with our churn cost calculator and acquisition vs retention comparator.

06/ what the formula leaves out
What the simple formula leaves out.
The calculator is deliberately simple. Four refinements matter once the number drives a budget.
Discounting. The research definition is stricter: Gupta, Lehmann and Stuart define a customer’s value as “the expected sum of discounted future earnings”, and Gupta et al. (2006) review the models built on it. HM Treasury’s Green Book discounts at 3.5% a year in real terms — a public-sector rate, under review, not your cost of capital, but a fair illustration.
Retention rises with tenure. One ÷ churn assumes every member is equally likely to leave each year. They are not: the likeliest leavers go first, so a cohort’s retention climbs as it ages (Fader and Hardie). Benchmark first-year and established members separately.
Prices move. The fee is held flat, so the result is in today’s pounds. UK CPI rose 3.1% in the 12 months to August 2026 (ONS); real growth is only what your dues rise beyond it.
VAT. Enter revenue net of VAT: most clubs’ and associations’ membership supplies are standard-rated, while some subscriptions to non-profit public-interest bodies — professional associations, learned societies, trade unions — may qualify for exemption (HMRC VAT Notice 701/5). Fee setting itself lives on membership pricing.

07/ how we calculate this
How we calculate this.
Average tenure is the inverse of churn (1 ÷ churn rate). We treat an LTV:CAC ratio of 3:1 as the minimum healthy benchmark, in line with membership-sector guidance — not just generic SaaS rules of thumb.
The formula
- Lifetime value = (annual subscription + annual ancillary spend) × average tenure − acquisition cost
- LTV:CAC ratio = gross LTV ÷ acquisition cost
