9 Membership Growth Metrics to Track (and How to Improve Them)

Wondering how healthy your membership site really is? As a membership owner, you should be! Understanding just a few key metrics can be the difference between steady growth and head-scratching cancellations.

But if you’re not a math whiz or marketing guru, there’s no need to worry. In this article, we’re breaking down the nine most important metrics to help you scale your membership. 

These metrics are the foundation for a healthy, thriving community, so even if you don’t follow them all, it’s worth including at least a few to make more informed decisions about your membership business. 

We’ll break these metrics down into two categories:

1. Member Engagement Metrics: How your members interact with your content and community.
2. Financial Performance Metrics: The money side of things, like revenue, profit, and growth potential.

Member Engagement Metrics

1. Active Members

This tells you how many people regularly log in and interact with your membership. Track active logins by day, week, or month. You can also dig deeper by looking at content views, lesson completions, likes, comments, and community posts.

Why does this matter?

Active members are happy members. When they're engaged and making progress, they're more likely to stick around. That means less cancellations and more money in your pocket. 

Boost active members by:

• Creating a warm, welcoming onboarding flow with clear next steps
• Sending friendly, personalized nudges via DMs or notifications
• Highlighting new or popular content
• Using fun gamification (badges or rewards)
• Hosting regular live sessions or office hours

How to calculate it:

Active Member % = (Active Members ÷ Total Members) × 100%

1. Define your tracking timeframe such as daily, weekly or monthly (recommended)
2. Decide what counts as an “Active Member”
3. Calculate the Active Member Rate

A simple spreadsheet could look something like this:

Active Member Goal:

An active community is the heartbeat of your membership site. 

Typically, seeing 40–60% of your members actively engaging with your content is a good sign that you’re on the right track. This means your members are logging in regularly, interacting with resources, and truly finding value in the community. 

If your active member percentage falls below this range, it might be time to consider fresh strategies to re-engage your audience and boost overall participation. Definitely aim for higher!

2. Content Consumption Metrics

This measures how much your members engage with your content (not just community activity or logins).

This includes the number of videos watched, total watch time, lessons completed, downloads made, or resources accessed. Usually, you measure this as a percentage.

Why does this matter?

High content consumption means your members see the value in your offering. If they’re watching, reading, or downloading, it’s working. Low numbers? It might be time to reassess what they really want.

Boost content consumption by:

• Keeping your content bite-sized and binge-worthy
• Creating clear, personalized learning paths or playlists
• Adding progress bars and visual trackers
• Including quizzes, assignments, or fun challenges
• Celebrating member wins

How to calculate it:

Content Consumption Rate % = (Number of content pieces accessed (or finished) ÷ Total available content pieces) × 100%

Depending on your platform, content consumption can be tracked at different levels of detail, such as views, partial completions, or full completions. Decide how granular you want to get based on your membership goals.

Example:

Total available lessons: 10
Average lessons accessed or completed by members: 6
Content Consumption Rate = (6 ÷ 10) × 100% = 60%

Content Consumption Goal:

There isn’t a universal “one-size-fits-all” target for content consumption. Most membership sites aim for at least a 50–60% consumption rate. 

If you’re consistently seeing rates of 60% or higher, that’s a sign your content is hitting the mark. Ultimately, your benchmark depends on your content type, how frequently it’s updated, and how you define “completion.” 

Watch for trends. If you notice your consumption rate dropping, it’s a good signal to reassess your content strategy.

3. Member Retention Rate

Your Member Retention Rate tells you how many of your members are sticking with you month after month. It highlights the success you're having at keeping existing members engaged, happy, and paying!

Why does this matter?

Retention impacts sustainability and profitability. It’s five times cheaper to keep a current member than it is to find a new one. And members who stick around longer are more likely to refer others, upgrade, and engage.

Quick Tip: If your retention drops, act fast. Send a survey, spark a conversation, or offer a check-in call. Early action can save relationships (and revenue).

Here are a few ways to boost member retention:

• Onboarding that delivers value from day one
• Helping them get a win in the first 30 days
• Gathering member feedback (through surveys, conversations, or community threads) and acting on it
• Building a supportive, friendly community space
• Keeping your content fresh, high-quality, and relevant
• Celebrating loyal, long-time members (shout-outs, rewards, perks)
• Creating personalized learning paths

“People come for the content, but stay for the community” — Stu McLaren

How to calculate it:

Member Retention Rate (%) = ((Members at end of period – New members acquired during period) ÷ Members at start of period) × 100%

Retention calculations can happen monthly, quarterly, or annually, depending on your goals. Consistency is key. Pick a timeframe that aligns best with your membership cycle and stick to it.

Example:

• Members at the start of the month: 150
• New members acquired during the month: 20
• Members at the end of the month: 155

Member Retention Rate = ((155 – 20) ÷ 150) × 100% = (135 ÷ 150) × 100% = 90%

In this example, your Member Retention Rate would be 90%, indicating strong member satisfaction and engagement.

Retention Rate Goal:

A healthy membership site often sees retention rates around 85–90% or higher. High retention signals that members find ongoing value and are less likely to cancel, saving you time and money in the long run. 

Even a small boost in retention rate can have a huge impact on your bottom line.

For example, increasing monthly retention from 90% to 95% in a 50-member, $20/month membership over 12 months can generate an additional $2,300!

4. Churn Rate

This is the flip side of retention—tracking how many members you're losing (vs. keeping). It measures the percentage of your members who cancel their membership during a specific time period, usually monthly or annually.

Why does this matter?

Churn gives you insight into the health and perceived value of your membership. High churn is a red flag. Even a slight reduction in churn can significantly boost your membership site's revenue.

Reduce churn by:

• Conducting quick exit surveys or interviews
• Offering a "pause" option instead of full cancellations
• Sending re-engagement emails to inactive members
• Targeting at-risk members (e.g., members who haven’t logged in or are nearing renewal)
• Fixing common churn triggers (like payment fails or confusing UX)
• Checking in with members who seem disengaged

How to calculate it:

Churn Rate (%) = (Number of memberships cancelled during period ÷ Total members at start of period) × 100%

Quick Tip: Churn rate is most commonly calculated on a monthly basis, which allows you to spot trends and intervene quickly.

Example:

Total members at the start of the month: 150
Memberships canceled during the month: 15
Churn Rate = (15 ÷ 150) × 100% = 10%

In this example, your Churn Rate is 10%. Lower churn percentages reflect a healthier, more sustainable membership site.

Financial Performance Metrics

5. Monthly Recurring Revenue

This is your predictable, consistent income from active subscriptions each month. It's one of the best indicators of your membership site's financial stability and growth potential.

Why does this matter?

It’s your financial foundation. Stable Monthly Recurring Revenue (MRR) means you can plan, hire, reinvest, and sleep a little easier at night.

You can boost MRR by:

• Offering tiered pricing to serve more audiences
• Encouraging annual plans with small discounts
• Selling add-ons (coaching, templates, resources)

How to calculate it:

MRR = Total Paying Members × Average Revenue per Member

Example:

Total Paying Members: 100
Average Revenue per Member: $50/month
MRR = 100 × $50 = $5,000/month

In this example, your Monthly Recurring Revenue would be $5,000 per month.

6. Customer Lifetime Value

This measures how much a single member is worth over their full membership journey.

Why does this matter?

The higher your Customer Lifetime Value (LTV), the more sustainable (and profitable) your membership becomes.

Here’s how to boost LTV:

• Improving retention through consistent, high-value content
• Offering premium or upsell content
• Introducing loyalty programs or exclusive tiers

How to calculate it:

LTV = Average Revenue per Member × Average Membership Duration

Example:

Average Revenue per Member: $50/month
Average Membership Duration: 12 months
LTV = $50 × 12 = $600 per member

In this example, your Customer Lifetime Value would be $600 per member.

7. Customer Acquisition Cost (CAC)

This is the average amount of money you spend to gain one new member. It helps you determine if your marketing and sales efforts are working.

Why does this matter?

A lower CAC means efficient growth. This can increase your profits and ensure long-term financial health. If it’s too high, it’s time to optimize your funnel. 

Quick Tip: Aim for a CAC that's lower than your Customer Lifetime Value (CLV). The larger the gap, the healthier your membership becomes.

Lower CAC by:

• Creating content that attracts (blogs, reels, SEO)
• Encouraging referrals from satisfied members
• Optimizing your marketing funnel to boost conversions
• Running retargeting campaigns for warm leads
• Partnering with related brands or creators
• Encouraging current members to share testimonials or create content about your memberships
• Optimizing your landing pages and checkout

“Stories are your most powerful marketing asset.” — Stu McLaren

How to calculate it:

CAC = Total Marketing Spend ÷ Number of New Members

Example:

Total Marketing Spend: $2,000
New Members Acquired: 40
CAC = $2,000 ÷ 40 = $50 per new member

In this example, your Customer Acquisition Cost is $50 per member.

8. Average Revenue Per User (ARPU)

This is your average monthly income per member.

Why does this matter?

Increasing ARPU means more revenue without needing more members.

You can boost ARPU by:

• Introducing premium membership tiers with added value
• Offering personalized upgrades or add-ons tailored to member interests
• Selling complementary products or resources that enhance the member experience
• Increasing your price (even small adjustments can have a huge impact on your ARPU)

How to calculate it:

ARPU = Total Monthly Revenue ÷ Total Members

Example:

Total Monthly Revenue: $5,000
Total Members: 100
ARPU = $5,000 ÷ 100 = $50 per member/month

In this example, your Average Revenue Per User is $50 per month.

9. LTV to CAC Ratio

The LTV to CAC Ratio measures the relationship between the lifetime value of a customer (LTV) and the cost to acquire that customer (CAC). 

This shows how profitable your member acquisition strategy is.

Why does this matter?

It’s the ROI on your growth efforts. A ratio of 3:1 or higher means you’re doing great, and you’re earning at least 3x more from a member than it costs to bring them in.

Quick Tip: Monitor and compare your LTV:CAC ratio month-over-month.

Improve your LTV:CAC ratio by:

• Increasing retention through exceptional member experiences and content
• Optimizing your marketing strategies to reduce acquisition costs
• Creating strategic upsells or higher-value membership tiers to raise LTV
• Leveraging referrals and organic marketing to lower CAC

How to calculate it:

LTV:CAC Ratio = Customer Lifetime Value (LTV) ÷ Customer Acquisition Cost (CAC)

Example:

Customer Lifetime Value (LTV): $600
Customer Acquisition Cost (CAC): $50
LTV:CAC Ratio = $600 ÷ $50 = 12:1

In this example, your LTV to CAC Ratio would be 12:1, showing very healthy profitability and growth.
