Churn rate vs. retention rate: Differences + How to calculate

Understanding churn rate versus retention rate is essential for SaaS and subscription businesses. These two metrics reveal who stays, who leaves, and what it means for your growth.

Churn rate vs. retention rate: Key differences

Track both metrics together to see the full picture. Churn shows where you're losing customers. Retention shows what's working.

When analyzed by customer segment or cohort, they reveal which customers succeed with your product and which struggle.

What is churn rate?

Churn rate is the percentage of customers or revenue lost over a specific time period. 

When a customer cancels their subscription, downgrades to a free plan, or simply stops using your product, they've churned. For SaaS businesses, churn directly impacts growth speed and profitability.

There are two primary types of churn that businesses need to track:

• Customer churn counts the number of customers who leave. If you start a month with 1,000 customers and 50 cancel, your customer churn rate is 5%. This metric reveals problems with product fit, customer experience, or competitive positioning.
• Revenue churn measures the monetary value lost from cancellations and downgrades. This comes in two flavors. Gross revenue churn shows total revenue lost. Net revenue churn factors in expansion revenue from existing customers who upgrade or increase usage.

A company can have positive net revenue retention even with customer churn. This happens when expansion revenue from existing customers is greater than the losses from those who leave.

Churn reveals critical truths about your business. High churn signals weak product-market fit, poor onboarding, inadequate support, or pricing that doesn't match value. It's an early warning system. Something fundamental needs fixing before growth becomes impossible.

What is the retention rate?

Retention rate is a metric that measures the percentage of customers, employees, or users who continue with a service, product, or organization over a specific period.

Churn focuses on who leaves. Retention shows who stays and why they stay. If your retention rate is 90%, nine out of 10 customers choose to stick around.

Retention tells you more than churn alone. It shows if your product delivers real value. It reveals how sticky your solution is. And it signals how well you fit into daily workflows. Strong retention means customers see you as essential.

Net retention takes this further. It factors in expansion revenue. When customers upgrade, add seats, or use more, revenue grows. That extra revenue can push net retention past 100%.

So your customer base grows in value, even if some leave. Top SaaS companies hit 120% net retention or higher. Their existing customers become a growth engine.

Retention boosts every other metric, too. It lifts lifetime value, improves unit economics, and takes pressure off sales and marketing. Less scrambling to replace lost customers. More room for steady, efficient growth.

How to calculate churn and retention

You can calculate churn and retention rate by following these steps:

• Customer churn rate formula: Customer Churn Rate = (Customers Lost During Period / Customers at Start of Period) × 100

Example: You start January with 500 customers. By the end of the month, 50 have canceled. Your monthly churn rate is (50 / 500) × 100 = 10%.

• Customer retention rate formula: Customer Retention Rate = ((Customers at End of Period - New Customers Acquired) / Customers at Start of Period) × 100

Example: You start January with 500 customers, acquire 75 new customers, and end with 525 customers. Your retention rate is ((525 - 75) / 500) × 100 = 90%.

Notice that new customers must be excluded from retention calculations. Retention measures how many existing customers stayed. Including new sign-ups inflates the number. It hides your true retention performance.

In our example, you had 10% churn and 90% retention. These add up to 100% when you measure the same group over the same period.

For revenue churn and retention, use the same formulas. Just swap customer counts for dollar amounts. Track monthly recurring revenue (MRR) or annual recurring revenue (ARR). You can do it at the start and end of each period.

Quick formula reference:

• Churn rate = Lost Customers ÷ Starting Customers × 100
• Retention rate = (Ending Customers - New Customers) ÷ Starting Customers × 100
• Revenue churn = Lost MRR ÷ Starting MRR × 100
• Net revenue retention = (Starting MRR + Expansion - Churn) ÷ Starting MRR × 100

Why these metrics matter

These metrics matter because:

Churn drains revenue fast. A SaaS company with $1 million in ARR and 5% monthly churn would lose about $460,000 a year without new sales. That's $38,000 in new revenue each month just to stay flat.

Churn shrinks customer value. If customers leave early, you only get a fraction of their potential revenue. But your cost to acquire them stays the same. Profits drop fast.

Retention compounds growth. When customers stay longer, every dollar you spend to get them keeps paying off. A company with 95% retention carries most of its revenue into the next month. That builds stable growth over time.

Retention signals product health. SaaS companies with a higher retention rate show that customers find real value. Those with net revenue retention above 120% often earn higher valuations from investors.

Together, churn and retention show the full picture of customer health. Tracking both leads to stronger, more stable growth.

Industry benchmarks and what "good" looks like

Benchmarks vary by business model, customer segment, and growth stage. But general guidelines exist:

• B2B SaaS companies should aim for a monthly churn below 2%.
• B2C subscription businesses should stay under 5% monthly churn.
• B2B SaaS companies should target an annual churn under 7%.
• Enterprise SaaS should achieve an annual churn below 5%.
• B2B SaaS monthly retention should stay above 95%.
• B2B SaaS annual retention should exceed 85%.
• Enterprise SaaS should maintain an annual retention between 90% and 95%.
• Median net revenue retention across SaaS companies hovers around 110%.
• Top quartile SaaS companies achieve net revenue retention of 120% or higher.

These benchmarks align with recent SaaS industry research from companies analyzing over 1,000 subscription businesses.

Enterprise B2B SaaS typically sees lower churn than SMB-focused products. Annual contracts show lower monthly churn than month-to-month billing. And mission-critical products retain better than nice-to-have tools.

Consumer subscriptions like streaming or fitness apps often see 5% to 10% monthly churn. Lower prices and discretionary spending make these easier to cancel.

Common mistakes and misconceptions 

Here are the most common errors to avoid:

• Including new customers in retention calculations: This makes your numbers look better than they are. Retention measures how many existing customers stayed. Always subtract new customers first.
• Tracking only one metric: Churn and retention together tell the full story. Track both to see the whole picture.
• Ignoring revenue churn: Customer churn counts cancellations but misses downgrades. A customer who drops from $500/month to $50/month is still a customer. But you've lost 90% of their revenue.
• Looking only at total churn: This hides key patterns. Enterprise customers might have 2% churn. SMB customers might show 8%. Break it down by customer type to spot problems.
• Mixing monthly and annual rates: A 5% monthly churn rate equals about 46% annual churn, not 60%. Pick one time frame and stick to it.
• Celebrating low churn without checking expansion: Low churn is good. But if no one is upgrading or using more, you're missing growth. Track net retention, too.
• Comparing to the wrong companies: Don't compare your monthly churn to companies with annual contracts. Find businesses like yours to benchmark against.

Strategies to improve retention and reduce churn

The first strategy to improve retention and reduce churn is to know your numbers. Improving them takes action across the customer lifecycle. More strategies include:

• Improve onboarding and time-to-value: Most churn happens in the first 90 days. Customers leave before they see value. Invest in onboarding that gets users to their "aha moment" fast. Set activation milestones and track how many new customers reach them.
• Analyze churn drivers through cohort analysis and feedback: Don't guess why customers leave. Segment churned customers by traits, behavior, and timing. Survey those who cancel. Common reasons include missing features, poor integrations, or pricing concerns.
• Strengthen engagement through feature adoption: Customers who use core features regularly rarely churn. Find which features correlate with retention. Then drive adoption through in-app messages, emails, and customer success outreach.
• Build proactive customer success programs: Don't wait for customers to reach out with problems. Track usage patterns and engagement scores. When engagement drops or key features go unused, have your team reach out early.
• Build win-back and expansion programs: Not all churn is permanent. Create win-back campaigns after you've fixed the issues that caused customers to leave. For retained customers, offer upgrades or new products as their needs grow.
• Track both customer and revenue churn regularly: Make these metrics visible across the company. Use dashboards and regular reports. Track trends monthly and dig into any sudden changes. Break down churn by segment, channel, and product tier to spot problem areas.
• Align pricing with value delivery: Pricing that doesn't match perceived value creates churn. Usage-based pricing can help by letting customers pay for what they use. Flexible pricing that grows with customer success aligns incentives and reduces sticker shock.

When to focus on each metric

Different business stages call for different priorities, though both metrics always matter.

• Early-stage companies: Focus on retention first. It proves product-market fit better than any other signal. If customers stay and expand, you've built something valuable. Get this right before scaling. A churn of 3% to 5% monthly is acceptable as you refine your customer profile.
• Growth-stage companies: Watch churn closely. A 5% monthly churn rate feels manageable at 100 customers. At 10,000, it's devastating. Track cohort retention to make sure new customers retain as well as early adopters. This phase requires investment in customer success infrastructure.
• Mature companies: Track both metrics closely. Aim for net revenue retention above 100%. Turn your existing customers into a growth engine. Focus on expansion, reducing downgrades, and keeping retention high. Executive dashboards should highlight both customer retention and net revenue retention.
• During product changes or market shifts: Measure more often. New feature launches, pricing changes, or competitive threats impact these metrics fast. Move from monthly to weekly or daily tracking during critical periods.

Conclusion

Churn rate versus retention rate answers the same question: Do customers want to keep using your product? Churn tells you when things break. Retention shows what's working. Together, they reveal the full picture of customer health.

Calculate both metrics the same way each time. Track trends over time. Use cohort analysis to learn which customers succeed. Then invest in retention programs that matter.

Winning subscription companies aren't just good at acquiring customers. They're great at keeping them, growing relationships, and turning happy customers into advocates. It starts with measurement. It continues with analysis. And it succeeds through a relentless focus on customer value.

Don't just know your numbers. Act on them. Every point of improvement in retention compounds over time. It can add up to millions in extra revenue and a much higher company value.

FAQs

What is a good churn rate for SaaS companies?

A good churn rate for SaaS companies depends on your business model and customer segment. For B2B SaaS firms, aim for monthly churn below 2% and annual churn under 7%, according to the Vitally research we mentioned earlier. 

Enterprise-focused SaaS should target annual churn below 5%. B2C subscriptions typically see a higher acceptable churn of 5% to 10% monthly.

Context matters here. Annual contracts, enterprise customers, and mission-critical products generally achieve lower churn. Month-to-month SMB services achieve higher churn.

How is retention different from customer loyalty?

Retention is different from customer loyalty because retention is a measurable metric. It shows whether customers renewed or not. Loyalty is an emotional state reflecting how they feel about your brand.

High retention often signals loyalty, but not always. Customers might stay due to switching costs, contracts, or a lack of options rather than genuine preference. True loyalty drives more than retention. It fuels advocacy, expansion, and word-of-mouth growth.

Can a business have a low churn rate but poor retention?

No, a business cannot have low churn but poor retention when measuring customer counts, since retention is the inverse of churn. But you can have low customer churn and poor revenue retention if customers are downgrading a lot.

You can also have solid overall retention that hides churn in high-value segments. Always check both customer and revenue metrics across different cohorts.
