Member lifetime value explained

How much is a new member worth to you? Not their first payment, but everything they will pay over the months or years they stay. That figure is called member lifetime value, often shortened to LTV, and it quietly answers some of the biggest questions a membership owner faces: how much you can afford to spend attracting someone, whether a retention project is worth the effort, and which kinds of members are most valuable to your business.

You do not need complex software to work it out. You need your average revenue per member, a sense of how long members stay, and a willingness to treat the answer as an estimate rather than a promise.

The simple calculation

For a monthly membership, lifetime value is the average monthly payment multiplied by the average number of months a member stays.

Lifetime value = average monthly revenue per member × average months a member stays

If you know your monthly churn rate, you can estimate the average length of membership as one divided by churn. If you need a refresher on that figure, start with calculating churn rate.

Take a hypothetical photography community charging $30 a month, with monthly churn of 5%. Average membership length is 1 ÷ 0.05 = 20 months. Lifetime value is $30 × 20 = $600.

If you have several price levels, use the average revenue per member across all of them: total monthly recurring revenue divided by the number of paying members.

Annual memberships and renewal rates

Professional associations, clubs and many other memberships bill yearly. The same logic works with years instead of months.

Say a professional association charges $240 a year in dues and 80% of members renew each year. Annual churn is 20%, so average membership length is 1 ÷ 0.20 = 5 years. Lifetime value is $240 × 5 = $1,200.

If you offer both monthly and annual options, calculate lifetime value for each group separately. Annual members often stay longer, partly because the decision to leave only comes up once a year. Seeing the two figures side by side tells you how hard to promote the annual option; the trade-offs are covered in offering both monthly and annual plans.

Making the estimate more honest

The simple formula is a good starting point, but it has blind spots. Three adjustments make it more realistic.

Use margin, not just revenue

Every member costs something to serve: payment processing fees, a share of hosting and software, perhaps printed materials or a coaching call. If the photography community spends about $5 per member per month on these, the margin per member is $25, and lifetime value on a margin basis is $25 × 20 = $500. That is the figure to use when deciding how much you can spend to win a member.

Cap the time horizon

If your churn is very low, the formula can suggest members stay for a decade or more. Maybe they will, but you cannot plan on it, and your membership may change a great deal in that time. Many owners cap lifetime value at three or five years to keep it grounded.

Be careful with small or new sites

If you launched recently, your churn figure is based on a few months and a small number of members. Early members are often your most enthusiastic, so their churn may be lower than what later members will show. Treat early lifetime value as a rough guess and revisit it every quarter.

Lifetime value by segment

An average across all members is useful. Averages by group are often more useful still. Calculate lifetime value separately for:

• Each membership level, to see whether your premium level earns its extra effort.
• Each acquisition channel, such as search, referrals, partnerships or paid ads. Members who arrive through a friend's recommendation may stay much longer than those who came through a promotion.
• Members who joined with and without a discount, to see whether promotions bring in members who stay or members who leave when the full price begins.

These comparisons often change where you put your energy. A channel that brings fewer members but twice the lifetime value may deserve more attention than the one that fills your sign-up count.

What lifetime value is good for

Setting an acquisition budget

If a member is worth $500 in margin over their lifetime, spending $400 to win each one leaves little room for error, while spending $100 is comfortable. Lifetime value gives you an upper limit on what advertising, affiliate commissions or free trials can cost you per member.

Justifying retention work

Small changes in churn have a large effect on lifetime value. In the photography example, reducing monthly churn from 5% to 4% increases average membership length from 20 to 25 months, and lifetime revenue from $600 to $750. Across 300 new members a year, that is an extra $45,000 in lifetime revenue from the same marketing. That kind of calculation helps you decide whether a better onboarding sequence or a new members-only event is worth building.

Checking your pricing

If lifetime value is low because members leave quickly, raising prices rarely fixes it; you need to fix whatever is making them leave. If members stay a long time and value is still low, your price may simply be too modest for what you deliver. It is worth revisiting pricing from the value you deliver with this number in hand.

Working out your own lifetime value

1. Calculate average monthly revenue per paying member.
2. Calculate average monthly churn over the last three to six months, or the annual renewal rate for yearly members.
3. Divide one by churn to estimate average membership length, and cap it at a sensible limit.
4. Multiply revenue per member by that length, then repeat the calculation using margin rather than revenue.
5. Repeat for each level and each main acquisition channel.
6. Write the figures down and recalculate every quarter, noting what changed and why.
