The Leak
What churn costs you
£45,000
Revenue lost every year · 150 members · 15% of total
Of this year's £300k member revenue
Cutting churn by just 3 points keeps £9,000 in the bucket every year — usually far cheaper than acquiring the same revenue from scratch.
At 15% churn you are holding members better than the 18% a typical membership organisation loses in a year — worth protecting.
Plug the leak — let's chat →Fifteen minutes, and we come to you with a view — not a pitch deck.
Set your numbers once. Every chart further down this page then answers in them: the base you keep, your rate against the sector, a member’s lifetime value and what each point of churn is worth.

02/ before using the tool
Turn member counts into a churn input
The live tool above takes annual churn, member count and annual revenue per member. If you only have opening and closing member counts, establish retention first, then enter its complement as churn. Use the same period and definition of active membership throughout.
Illustrative arithmetic: start with 1,000 members, add 200 new members who are all still active at the end, and finish with 950. Existing members retained = 950 − 200 = 750. Retention = 750 ÷ 1,000 × 100 = 75%; churn = 25%. These are example inputs, not a sector benchmark.
If some joiners also left during the period, subtract only the new members still present at the end. Better still, follow the opening cohort by member ID. Do not count the whole recruitment total as though every joiner survived.
Use an annual period for this tool. A monthly churn percentage entered as an annual rate understates losses. For definitions and the difference between retained members and members due to renew, use the membership retention rate guide.
Our arithmetic; assumes no reactivations or membership-status reclassifications.
03/ the compound effect
Churn compounds.
Most membership organisations underestimate the compound impact of churn.
Every member lost takes their future revenue too.
The membership retention calculator shows how churn compounds. A 15% annual churn doesn’t mean 45% loss over 3 years. It is actually 38.6%, because each year’s loss comes from a shrinking base.
The chart runs your own numbers five years forward with nobody replaced. That is the base you would have left if recruitment stopped tomorrow.
The two readouts under it set the simple sum against the compounded figure, in your churn rate.
Marketing General Inc.’s Tony Rossell draws the other half of the lesson. The median renewal rate has barely moved in nearly a decade, so unless an association is fixing a major flaw, it “cannot renew its way into growth” (MGI 2026, commentary on a US industry survey).
Retention protects the base; recruitment grows it. You need both numbers.
Use our membership retention calculator above to model your retention economics and see what improving retention could mean for your organisation.
It works equally well as a customer retention calculator for subscription businesses and clubs.

Understanding Your Membership Retention Calculator Results
Retention rate benchmarks. Above the 82% median, you’re ahead of the sector.
Below 75% among first-year members signals an onboarding problem.
Sources: Marketing General Inc.’s 2026 report (82%) and its 2024 Membership Marketing Benchmarking Report (75%).
The ring takes your churn from the calculator and shows what you keep, with the 82% median as the grey arc behind it.
Financial impact. Acquiring a new member can cost five to 25 times more than retaining an existing one, according to Harvard Business Review.
Our calculator shows your specific numbers based on your member value and costs.
What moves the number. In a peer-reviewed study of professional associations, core services performance was the only construct found to affect member retention (Gruen, Summers and Acito, 2000).
A survey of 13,229 members of eighteen associations found perceived personal and professional benefits went with stronger intentions to renew (Ki and Wang, 2016).
So the lever is the service itself, not the reminder schedule alone.

Retention counts every loss, so this compares well with a renewal figure.
Retention here is 100 − your churn. Benchmarks: median renewal 82% (MGI 2026) and first-year renewal 75% (MGI 2024). Two editions, named separately; both are US industry surveys of renewal, not all-cause retention.

05/ retention vs renewal
Retention Rate vs Renewal Rate: What’s the Difference?
The two terms get used interchangeably, but they measure different things.
Your renewal rate is the percentage of members who renewed when they were eligible to renew.
Your retention rate accounts for all losses across the year: non-renewals, mid-term cancellations, lapsed payments and resignations.
Renewal rate is usually the higher number, so check which one a benchmark refers to before comparing. The widely cited 82% sector median is a renewal figure.
The calculator above works in churn, so the rate it implies is a retention rate. Read it against a renewal median and you are, if anything, being hard on yourself.
The formula, worked examples and the benchmark tables by organisation type are on membership retention rate.
If your numbers fall short on either measure, our member retention services and specialist membership retention agency team can help you close the gap.

06/ methodology
How the Membership Retention Calculator Works
Our membership retention calculator uses industry-standard formulas. The tabs list each one.
The calculator assumes a stable membership base for projections, though in reality, acquisition efforts would partially offset churn.
This makes our calculations conservative. The actual impact of poor retention is often worse.
The lifetime value line is the one most worth knowing. Average tenure is one divided by churn, so 20% churn means five years, the worked example Tony Rossell uses to make the case for recruitment budgets.
The tiles and chart beside this run that sum in your numbers, against the median and against your own target.
Core Calculations
- Annual Revenue Loss: Members Lost × Average Member Value
- 3-Year Compound Loss: Year 1 + (Year 1 × (1 - Churn)) + (Year 1 × (1 - Churn)²)
- Retention Improvement Value: (Current Churn - Improved Churn) × Members × Member Value
- Lifetime Value Impact: Member Value × (1 / Churn Rate)
Churn Rate Formula
Churn Rate = (Lost Members / Starting Members) × 100
- If you start the year with 1,000 members and lose 150, your churn rate is 15%.
- Your retention rate is the inverse: 85%.

Marketing General Inc.’s benchmarking reports give the sector’s reference figures: a median renewal rate across membership organisations of 82% (2026 report) and a median first-year renewal rate of 75% (2024 Membership Marketing Benchmarking Report).
New members churn markedly faster than established ones.
Use these benchmarks to compare your results from the membership retention calculator. Remember they are renewal figures, so your all-cause retention rate will typically be a little lower.
One simplification to keep in mind: the calculator applies a single churn rate to every member.
In practice retention climbs as a cohort ages, because the members most likely to go are the first to leave (Fader and Hardie, 2007, peer-reviewed subscription data).
That is one more reason to benchmark first-year renewal on its own.

Set the target churn improvement in the calculator and the bar for your target moves with it.
Target by response, not only by risk. Field experiments found the customers at highest risk of leaving are not necessarily the best targets for a retention offer (Ascarza, 2018).
Test who responds before you spend.
Auto-renewal is getting rules. The Digital Markets, Competition and Consumers Act 2024 brings reminder notices, easy online exit and a 14-day renewal cooling-off period to consumer subscriptions, expected in 2027.
The government says it will exclude certain charitable cultural and heritage memberships (GOV.UK, April 2026). Check whether yours is in scope before redesigning renewal.
Renewal mechanics live on membership renewals.

09/ before you model
Bring numbers you can reconcile
Before moving a slider, choose one membership period and one counting unit. Use people for individual membership or organisations for corporate membership. A corporate account with several portal users is still one paying account if that is the unit in your register. Write that choice beside the result.
Take a dated export rather than a current dashboard total that changes while you work. Keep the starting membership list, the end list and the additions during the period together. Use persistent member IDs to find which starters remained. Document how your organisation treats grace periods, resignations and reinstatements, then apply that treatment consistently.
Do not put total income into the revenue-per-member field. Decide whether you are modelling dues alone or dues plus attributable ancillary income, and use the same basis in every scenario. The calculation is a revenue model: it does not deduct servicing costs or the cost of the intervention.
The TUC Digital Lab describes different retention figures reported for the same union (sector body workshop guidance). The practical audit here is our way to make your inputs repeatable; it is not a new benchmark.

10/ from model to decision
Record the scenario before you spend
Run your current position first, then a modest improvement and an ambitious improvement. Keep member count and annual revenue per member fixed while changing churn. Otherwise a larger membership base can make an intervention appear more valuable without showing whether retention improved.
For a fictional organisation with 1,000 members and £300 annual revenue per member, reducing churn from 15% to 12% keeps an additional 30 members in the first year. At the same revenue basis that is £9,000 in annual revenue. This is arithmetic, not a forecast or an outcome delivered by Membership Quest.
Write down the proposed action next to the scenario: what it costs, which members it reaches, who owns it and when you will review the result. If the programme costs more than the modelled first-year revenue protected, the business case needs other explicitly stated benefits or a longer horizon. Avoid calling protected revenue profit.
Take the calculation to a planning conversation with its assumptions attached. The membership retention plan is where the action and review cadence belong; the retention-rate guide is where you choose the comparable measure.
Fictional worked example; 30 × £300. Revenue only, before programme and service costs.
