Gross MRR churn
DEFINITION
Gross MRR churn is the share of monthly recurring revenue a business loses over a period from cancellations and downgrades, before any offsetting gains from existing customers are counted.
TABLE OF CONTENTS
RELATED TERMS
Gross MRR churn is the share of monthly recurring revenue a business loses over a period from cancellations and downgrades, before any offsetting gains from existing customers are counted. It measures revenue lost from the current customer base and never nets that loss against expansion, so it shows the full weight of what is leaving. Because it ignores expansion, gross MRR churn is the cleaner read on how well a business retains the revenue it already has. Net MRR churn can look flat or even negative when upgrades mask heavy cancellations, but gross MRR churn keeps the losses visible on their own.
A subscription platform such as Recurly tracks the underlying movements that feed this figure, including cancellations, downgrades, and expansion, and reports them as separate categories so a business can build the gross view it needs from the components available.
Why gross MRR churn matters for subscription businesses
Gross MRR churn is a retention health check that cannot be masked by expansion growth. A company can post strong top-line growth while quietly losing a large slice of its base each month, and only a gross measure exposes that. Watching it over time shows whether the product keeps customers paying at the level they signed up for. It matters for a few concrete reasons:
It isolates the losses, so a retention problem is not masked by upsell.
It feeds growth planning, because revenue lost to churn is revenue new sales must replace before the business grows at all.
It signals product and pricing fit, since rising downgrades often point to customers who find the plan too expensive for the value they get.
How to calculate gross MRR churn
Gross MRR churn is usually expressed as a rate over a chosen period, most often a month. Gross MRR churn rate = (Churned MRR + Downgrade MRR) / MRR at start of period x 100 Where:
Churned MRR is recurring revenue lost from customers who cancel outright.
Downgrade MRR is recurring revenue lost from customers who move to a cheaper plan or reduce quantity.
MRR at start of period is the recurring revenue on the books at the beginning of the period.
To calculate it:
Take total MRR at the start of the period.
Add up MRR lost to cancellations during the period.
Add up MRR lost to downgrades during the period.
Sum the cancellation and downgrade losses.
Divide that sum by the starting MRR and multiply by 100.
Illustrative example (hypothetical figures):
MRR at start of month: $100,000
MRR lost to cancellations: $6,000
MRR lost to downgrades: $2,000
Gross MRR churn rate = (6,000 + 2,000) / 100,000 x 100
= 8,000 / 100,000 x 100
= 8%
In this example the business loses 8 percent of its starting recurring revenue over the month, regardless of any new sales or upgrades in the same period.
How to use gross MRR churn
Track gross MRR churn on a consistent period and cohort so the number is comparable month to month. Read it next to net MRR churn: the gap between the two tells you how much expansion is offsetting losses, and a wide gap can be a warning that growth depends on a few accounts upgrading rather than on broad retention. Useful ways to put it to work:
Segment by plan, cohort, or acquisition channel to find where losses concentrate.
Split the cancellation and downgrade components, since they usually call for different fixes.
Watch for involuntary churn inside the cancellation figure, because failed payments inflate gross churn without reflecting a real decision to leave.
Benefits and examples
Measuring gross MRR churn gives a business an honest floor for its retention. Because the metric refuses to net out expansion, it prevents a healthy-looking net number from hiding a leaky base, and it makes the cost of churn explicit when planning how much new revenue is needed to grow. For example, a company with $100,000 in starting MRR and 8 percent gross MRR churn loses $8,000 of recurring revenue that month before it books a single new sale. If leadership only watched a net figure that expansion pushed down to 2 percent, they might assume retention was strong and under-invest in fixing cancellations. The gross view shows that new and expansion revenue has to cover an $8,000 hole every month just to stay level.
Frequently asked questions
What is the difference between gross and net MRR churn? Gross MRR churn counts only revenue lost to cancellations and downgrades. Net MRR churn subtracts expansion revenue from existing customers, so it can be lower than gross churn and can even be negative when expansion outweighs losses.
Should gross MRR churn include involuntary churn? Yes. Revenue lost to failed payments still leaves the base, so it belongs in gross MRR churn. It is worth tracking separately, though, because failed payments can often be recovered rather than treated as a lost customer.
What is a good gross MRR churn rate? Lower is better, and the acceptable range varies by segment and contract length.
Is gross MRR churn measured monthly or annually? It can be either, but it is most often reported monthly because it is built on monthly recurring revenue. Annual figures should be calculated carefully rather than by simply multiplying a monthly rate by twelve.
