Unlocking scalable AI revenue: Challenges and strategies for 2026

Customer attrition is when customers stop doing business with you — and it hugely impacts your growth and profitability. Here's how to calculate your attrition rate and reduce it with smarter pricing, billing, and retention strategies.
Customer attrition is the share of customers who stop doing business with you during a period. You’ll also hear client attrition, customer turnover, or customer defection used for the same idea.
Retail teams often tag customers as churned after a set period of inactivity. Subscription teams see attrition when someone cancels or fails to renew.
Acquisition matters because it can be expensive. Your growth stalls if too many customers leave before you earn back acquisition and onboarding costs. Teams track attrition to spot problems in onboarding, pricing, support, billing, and product-market fit.
Use these common drivers to structure your investigation:
Most attrition drivers like these trace back to a value perception problem, and pricing and packaging strategies can fix them.
Good monetization design aligns what customers pay with the outcomes they achieve, making every dollar feel justified. Flexible packaging options that allow a pause and hybrid pricing models also reduce involuntary churn.
You calculate the attrition by dividing the number of customers lost in the period by the number of customers you had at the start. Then multiply the result by 100. Here’s a quick look at the formula:
Example: You begin January with 500 customers and 25 leave by month-end. Attrition rate = 25 ÷ 500 × 100 = 5%. Track monthly for fast feedback and annually to see trends. Don’t multiply a monthly rate by 12; compounding makes that inaccurate.
Tip: Track attrition alongside revenue churn to understand the value you’re losing, not only the count of accounts.

When tracking customer attrition monthly versus annually, the timeframe you consider will naturally impact the rate. A monthly rate provides a more immediate snapshot of customer loss to quickly spot potential issues.
However, monthly fluctuations can sometimes be volatile. An annual rate offers a broader perspective, smoothing out short-term variations and revealing longer-term trends in customer retention.
It's common for SaaS businesses to monitor both monthly and annual rates to gain a holistic view. Keep in mind that simply multiplying a monthly rate by 12 doesn't always give an accurate annual rate due to compounding effects.
Finally, it's important to consider the impact of upgrades and downgrades on your attrition metrics. While a customer who downgrades their subscription isn't technically leaving your service entirely, it represents a contraction in revenue.
Conversely, an upgrade increases revenue. Traditional attrition rate calculations typically focus on complete customer loss.
Some companies track metrics like net revenue retention (NRR), which factors in upgrades, downgrades, and churn. This metric shows the overall change in recurring revenue from existing customers.
Remember: A customer completely leaving is still considered attrition, but downgrades signal a potential risk or a change in customer needs that's crucial to monitor.
Note: To connect upgrades, downgrades, and churn into a single revenue view, read our guide to net dollar retention.
People use the words interchangeably. In practice, attrition usually means customers lost, while churn can mean customers lost or recurring revenue lost. Many teams track all three: customer attrition, revenue churn, and retention.
Why the distinction helps: You could lose many low-revenue accounts and still see low revenue churn, or lose a few large accounts and see high revenue churn. Use both views when you plan pricing and success motions.

You analyze customer attrition effectively by first understanding not just the what, but also the why and the who behind it. A thorough customer attrition analysis involves both quantitative and qualitative methods.
This involves looking at hard data to identify patterns and trends. Think:
This involves gathering insights directly from customers to understand their reasons for leaving.
Breaking down your customer base into smaller groups can reveal valuable insights into attrition drivers. Consider segmenting by:
Using data to predict and understand churn can help proactively identify and engage at-risk customers.
