Churn Rate: Formula, Benchmarks and How to Reduce It
Churn rate explained: customer and revenue churn formulas, worked examples, benchmarks, voluntary vs involuntary churn and practical ways to reduce churn in 2026.
Churn rate is the percentage of customers (or revenue) you lose over a period. The basic formula is customers lost during the period / customers at the start of the period x 100. If you start a month with 200 clients and 6 cancel, your monthly churn rate is 3%. Reducing it usually comes down to three things: onboarding new customers well, fixing failed payments, and catching unhappy customers before they cancel.
Churn matters to any business with repeat or recurring revenue: subscriptions and SaaS, but also cleaning contracts, bookkeeping retainers, maintenance plans, memberships and agencies on monthly fees. A small change in churn has a big effect on growth, because every customer you keep is one you do not have to replace.
Churn rate formulas
| Metric | Formula | Use it to... |
|---|---|---|
| Customer churn rate | Customers lost / customers at start of period | Track how many accounts leave |
| Gross revenue churn | (Lost MRR from cancellations + downgrades) / MRR at start | Track how much recurring revenue leaves |
| Net revenue churn | (Lost MRR - expansion MRR) / MRR at start | Show whether upgrades offset losses |
| Retention rate | 1 - churn rate (for a cohort with no new customers) | Report the positive side |
| Net revenue retention (NRR) | (Start MRR + expansion - contraction - churned MRR) / start MRR | Investor-friendly view of the base |
MRR here means monthly recurring revenue. Customer churn and revenue churn can tell different stories: losing ten small clients may matter less than losing one large one.
Worked example: customer and revenue churn
An illustrative example. A bookkeeping firm bills clients on monthly retainers.
| Item | Clients | MRR |
|---|---|---|
| Start of October | 80 | $32,000 |
| Cancelled during October | 4 | -$1,200 |
| Downgraded to a smaller package | 2 | -$300 |
| Upgraded (added payroll service) | 3 | +$900 |
| New clients in October | 5 | +$2,000 |
- Customer churn: 4 / 80 = 5.0% (new clients are excluded).
- Gross revenue churn: ($1,200 + $300) / $32,000 = 4.7%.
- Net revenue churn: ($1,500 - $900) / $32,000 = 1.9%.
- Net revenue retention: ($32,000 + $900 - $300 - $1,200) / $32,000 = 98.1%.
The firm loses 5% of clients but only 1.9% of net recurring revenue, because upgrades cover most of the gap. Note that the four cancelled clients were mostly small accounts.
Monthly vs annual churn
Churn compounds. Annual churn = 1 - (1 - monthly churn)12. A 5% monthly rate equals about 46% a year, not 60%. Always label which period you mean.
What is a good churn rate? Benchmarks
Benchmarks vary widely by price point, contract length and customer type. Recurly, a subscription billing platform, publishes benchmarks from its network data. Its churn rate benchmark page (July 2026 data, presented as median annual rates) shows:
| Segment | Total churn | Voluntary | Involuntary |
|---|---|---|---|
| All industries | 3.60% | 2.34% | 1.25% |
| SaaS | 3.22% | 2.16% | 1.06% |
| Business and professional services | 3.44% | 2.27% | 1.18% |
| Ecommerce subscriptions | 4.25% | 2.87% | 1.38% |
Two lessons stand out. First, roughly a third of churn in these figures is involuntary, meaning customers lost to failed payments rather than a decision to leave. Second, your own numbers may look very different: small businesses on month-to-month terms with low prices often see much higher churn than a billing platform's median. Use benchmarks for context and your own trend as the real target.
Voluntary vs involuntary churn
| Type | Common causes | Main fixes |
|---|---|---|
| Voluntary | Poor onboarding, not seeing value, price, service problems, switching to a competitor, business closing | Better onboarding, regular check-ins, NPS follow-up, flexible plans, pause options |
| Involuntary | Expired cards, insufficient funds, bank declines, outdated billing contact | Card updater services, smart retries, reminder emails before expiry, ACH or direct debit options |
How to reduce churn: 10 practical steps
- Onboard properly. Most cancellations trace back to the first 60-90 days. Use a client onboarding checklist so every new customer gets a quick early win.
- Set expectations in writing. Clear scope and terms prevent "this is not what I expected" cancellations.
- Measure satisfaction. Run a Net Promoter Score survey and call every detractor.
- Watch for warning signs. Reduced usage, late payments, missed meetings and a new decision-maker are early signals.
- Fix failed payments. Retry failed charges, send card-expiry reminders, and offer bank payment options. Our guide to recurring payments for small business covers setup.
- Offer a pause or downgrade. A smaller plan keeps revenue and the relationship.
- Show value regularly. Monthly reports of what you did and the results.
- Ask why people leave. A one-question exit survey reveals patterns.
- Price for commitment. Annual plans with a modest discount reduce churn opportunities.
- Handle price increases carefully. Give notice and explain added value; see how to raise prices without losing customers.
How churn connects to lifetime value and acquisition cost
A simple estimate of average customer lifetime is 1 / churn rate. At 4% monthly churn, the average customer stays about 25 months; at 2%, about 50 months. Multiply by average monthly gross profit per customer to get customer lifetime value. Compare that with what it costs you to win each new customer; if churn rises, the amount you can afford to spend winning each customer falls. These links are the core of unit economics for any recurring business.
Churn for service businesses without subscriptions
Not every business has a clean "cancel" button. A cleaning company, accountant or dog groomer loses customers quietly: they just stop booking. To measure churn in that case, define an inactivity rule that fits your normal buying cycle.
| Business | Normal cycle | Reasonable "churned" rule |
|---|---|---|
| Hair salon | Every 6-8 weeks | No visit in 4 months |
| Residential cleaning | Weekly or fortnightly | No booking in 6 weeks |
| Tax preparer | Once a year | Did not return for this year's filing |
| Freelance designer | Several projects a year | No new project in 12 months |
| HVAC maintenance | Twice a year | Missed two scheduled services |
Then calculate churn exactly as before: customers who became inactive during the period divided by active customers at the start. Your invoicing records are the easiest data source. Export a list of clients and their last invoice date, and anyone past your inactivity window is a churned customer. That same list is your win-back campaign: a personal note or a short offer to clients who have drifted away often brings a few back.
Running a churn review: step by step
- Pull a list of every customer lost in the last quarter, with their start date, plan or spend, and last invoice.
- Record the reason for each, from exit surveys, emails or your own notes. Use a short list of categories: price, value, service issue, business closed, moved to competitor, payment failed, unknown.
- Count by reason and by customer age. If most losses happen in the first three months, onboarding is the problem. If they cluster after a price increase, pricing or communication is.
- Pick the single biggest fixable reason and assign one change, for example a 30-day check-in call for every new client.
- Repeat next quarter and compare.
Failed payments deserve their own line in this review. If customers are leaving because a card expired and nobody noticed, the fix is administrative: payment reminders before a card expires, a polite notice when a payment fails, and an easy way to update payment details. Our payment reminder email templates can be adapted for failed-payment notices.
Common churn calculation mistakes
- Counting new customers in the denominator. This understates churn in fast-growing months.
- Mixing periods. Comparing a monthly figure with an annual benchmark.
- Ignoring revenue. Customer churn alone hides the loss of a big account.
- Treating failed payments as voluntary. You miss the easiest fixes.
- Annual contracts. Customers on annual terms can only churn at renewal, so measure renewal rate for that group separately.
What to do when a customer asks to cancel
A cancellation request is not always final. Handle it respectfully and quickly:
- Acknowledge and confirm the request promptly. Never make cancelling difficult; hidden or obstructive cancellation processes damage trust and can breach consumer protection rules in some places.
- Ask one question: "Can I ask what prompted this?" Record the answer.
- Offer one relevant alternative if it genuinely fits: a pause, a smaller plan or a fix to the problem they named. Do not pressure.
- Close cleanly. Send a final invoice or confirmation showing the last billing period and any prorated credit, and thank them.
- Leave the door open. Former customers who left on good terms come back more often than you might expect, and they count as reactivations rather than new acquisitions.
Keep a simple log of every cancellation conversation: date, plan, tenure, stated reason and what you offered. After a few months, that log is more useful than any benchmark, because it shows exactly why your own customers leave and which offers, if any, actually kept them. Share the patterns with anyone who handles onboarding or billing so the fixes reach the start of the customer relationship, not just the end.
Billing clarity reduces churn
Confusing invoices, surprise charges and failed payments drive a surprising share of cancellations. Clear, consistent recurring invoices that show the period covered, the plan and any proration help clients see what they pay for; our SaaS subscription invoice template and recurring invoices guide show how. For one-off or monthly billing, you can create a clean invoice with our free invoice generator, with no sign-up required, and download it as a PDF.
Frequently asked questions
How do you calculate churn rate?
Customer churn rate equals customers lost during a period divided by customers at the start of that period, multiplied by 100. If you start the month with 200 customers and 6 cancel, churn is 6 / 200 = 3%. Do not include customers who joined during the month in the denominator or the lost count, or you will distort the result. Use the same period length every time so results are comparable.
What is a good churn rate?
It depends on your business model, price point and whether you measure monthly or annually. Recurly's subscription benchmarks for July 2026 put median churn around 3% to 4% for SaaS and business services, reported on the page as annual medians. Small businesses selling low-priced monthly services typically see higher churn than those with annual contracts. Your own trend over time is the most useful benchmark.
What is the difference between voluntary and involuntary churn?
Voluntary churn is when a customer actively decides to cancel, for example because of price, poor fit or switching to a competitor. Involuntary churn happens when a customer is lost because a payment fails, such as an expired card or insufficient funds, even though they did not intend to leave. Involuntary churn is often a significant share of total churn and is usually the easiest to reduce with better billing processes.
What is negative churn?
Negative churn, or net negative revenue churn, happens when expansion revenue from existing customers, such as upgrades, extra seats or add-ons, exceeds the revenue you lose from cancellations and downgrades. Your revenue from the existing customer base grows even without new customers. It is a sign of strong product value and pricing that scales with customer usage, and it shows up as net revenue retention above 100%.
How do I convert monthly churn to annual churn?
Do not multiply by 12. Use compounding: annual churn equals 1 minus (1 minus monthly churn) to the power of 12. A 3% monthly churn rate gives 1 minus 0.97 to the 12th power, which is about 30.6% a year, not 36%. Always state whether a churn figure is monthly or annual, because the difference is large and comparing the two leads to wrong conclusions.
How does churn affect customer lifetime value?
Churn and customer lifetime are directly linked. A simple estimate of average customer lifetime is 1 divided by the churn rate for the period: 4% monthly churn implies an average lifetime of about 25 months. Multiply that by average monthly gross profit per customer to estimate lifetime value. Cutting churn from 4% to 3% raises the average lifetime to about 33 months, which is a large gain in value.
