What is Revenue Churn?

Revenue churn measures how much recurring revenue you lost in a period, as a percentage of what you started with. Where customer churn counts departures equally, revenue churn weights each one by what it was worth - which is why a month can look calm by one measure and alarming by the other.

What Is Revenue Churn?

Revenue churn is the proportion of starting MRR lost to cancellations and downgrades over a period. It comes in two forms, and the difference matters:

• Gross revenue churn counts only what left: churned MRR plus contraction MRR. It cannot go below zero and it never looks flattering.
• Net revenue churn subtracts expansion revenue from those losses. It can go negative, which is the state known as net negative churn.

Quote gross churn when you want to know how leaky the bucket is. Quote net churn when you want to know whether the bucket is filling. Quoting net churn while calling it "churn" is the most common way founders accidentally overstate retention.

How Do You Calculate Revenue Churn?

Gross Revenue Churn = (Churned MRR + Contraction MRR) ÷ Starting MRR × 100

A worked example over one month:

• MRR at the start: $100,000
• Revenue lost to cancellations: $2,500
• Revenue lost to downgrades: $1,000
• Expansion from existing customers: $4,000

Gross revenue churn = ($2,500 + $1,000) ÷ $100,000 × 100 = 3.5%

Net revenue churn = ($3,500 − $4,000) ÷ $100,000 × 100 = −0.5%

Both numbers are true. The first says you lost 3.5% of the base. The second says expansion more than covered it. A business reporting only the second is not lying, but it is not describing the leak either.

Why Does Revenue Churn Matter More Than Customer Churn?

It reflects what you actually lose. Losing one account paying $5,000 a month and losing fifty paying $100 are identical events to customer churn and very different events to the business.

It exposes concentration risk. When revenue churn regularly runs well above customer churn, your revenue is concentrated in a small number of large accounts, and each one leaving is a material event.

It is the input to retention maths. Gross revenue retention is simply 100% minus gross revenue churn, and it is the figure investors ask for when they want to know how the base behaves before expansion flatters it.

What Is a Good Revenue Churn Rate?

Segment	Healthy monthly gross revenue churn
Enterprise B2B	Under 1%
Mid-market B2B	1–2%
SMB-focused SaaS	2–4%
B2C / prosumer	3–6%

Below 1% monthly is excellent by any standard. Above 5% monthly means you are rebuilding the majority of your revenue base annually, and no acquisition engine outruns that indefinitely.

Compare gross revenue churn against customer churn as a pair. If revenue churn runs consistently higher, your larger accounts are leaving. If it runs lower, you are losing your smallest customers - still worth fixing, but far less urgent.

How Do You Reduce Revenue Churn?

Work the largest accounts first. Revenue churn is dominated by a handful of departures. Ranking at-risk customers by MRR rather than by risk score alone concentrates effort where a save is worth the most.

Treat downgrades as early warnings. Contraction usually precedes cancellation. A customer cutting seats is telling you something months before they leave.

Recover failed payments. Involuntary churn shows up in revenue churn identically to a deliberate cancellation, and it is the cheapest category to fix because nobody decided to leave.

Sell annual to the accounts you cannot afford to lose. It does not prevent churn, but it moves the decision point twelve months out and gives you time to fix the relationship.

How Do You Track Revenue Churn?

Chartsy separates churned MRR from contraction MRR in every period and calculates both gross and net revenue churn from your Stripe or Paddle records, so the two are never accidentally conflated. Involuntary churn from failed payments is reported separately, because the fix is operational rather than a product problem.
