Monthly recurring revenue is the normalised, predictable subscription revenue a business earns in a month. It excludes one-off fees and it is not the same figure as statutory revenue in the accounts.
What MRR stands for
MRR is monthly recurring revenue. It counts the contracted, repeatable revenue a business expects each month from its active subscriptions, normalised to a monthly amount so that annual and quarterly plans can sit in the same total. Implementation fees, professional services and one-off charges are excluded, because the point of the metric is predictability rather than size.
How MRR is calculated
The simplest version is the sum of every active subscription normalised to a month. The shorthand most teams use is active customers multiplied by average revenue per user per month, which gets you to the same place when your plans are reasonably uniform and drifts when they are not.
Movement is where the useful detail lives. New MRR from new customers, expansion MRR from upgrades, contraction MRR from downgrades, and churned MRR from cancellations net out to the change in the month. A total that is flat can be hiding heavy churn offset by heavy expansion, and only the movement view shows it.
| What it is | What it tells you | |
|---|---|---|
| New MRR | Recurring revenue added by customers who joined this month. | Whether acquisition is actually working, separate from how the existing base is behaving. |
| Expansion MRR | Additional recurring revenue from existing customers. | Whether the product earns more from a customer over time. This is the line investors look for first. |
| Contraction MRR | Revenue lost to downgrades, without the customer leaving. | An early warning that reads as softness before it ever reads as churn. |
| Churned MRR | Recurring revenue lost to cancellations and non-renewals. | What the base loses if nothing changes, which is the floor your forecast has to clear. |
MRR is not the revenue line in your accounts
This trips up more founders than any other part of the metric. MRR is an operating measure of the subscription base at a point in time. Statutory revenue is governed by the recognition rules in the AASB accounting standards, which decide when revenue is earned rather than when it is contracted or billed. The two figures rarely match and are not supposed to.
Pricing structure is what widens the gap. Pricing in a subscriptions-based business is very different from pricing in a product-based business.[1] Usage tiers, annual prepayments, discounts and mid-term upgrades all need a stated treatment, and once someone has written that treatment down the number stops moving for reasons nobody can explain.
The same discipline decides whether your model holds up. Here is what founders get wrong in the financial models they take to investors.
Who should own the MRR number
In the early days it lives in the billing system and the founder reads it off a dashboard. That works until it does not. Founder-led finance does not scale at all, and eventually it runs its course, showing up as a scrambled financial model and cash conversations that are more of a guess than a position.[2] An MRR figure that changes depending on who pulled it is an early symptom of the same thing.
Which hire fixes it depends on what you need from the number. The biggest difference between a financial controller and a Head of Finance is that a controller focuses on financial controls, compliance and reporting, while a Head of Finance is broader and covers forward-looking work like financial modelling, FP&A, budgeting and forecasting.[3] If MRR is being reported inconsistently, a controller solves it. If MRR needs to drive a hiring plan and a fundraise, it needs the broader hire.
Either way, the change a founder feels is the same. The right finance hire starts buying back a founder's attention by taking ambiguity and making it clear, and by absorbing recurring finance decisions so they stop landing on the founder's desk.[4] The MRR definition is one of those decisions, and it should only be made once.
The other half of the movement view is what churn means and who should own it.
Common questions
What does MRR mean?
MRR stands for monthly recurring revenue. It is the predictable subscription revenue a business expects to earn in a month, normalised so that annual and quarterly plans can be added into one monthly figure. One-off charges such as implementation fees and professional services are excluded, because the metric exists to measure predictability rather than total billings.
How is MRR calculated?
Sum every active subscription normalised to a monthly value. The common shorthand is active customers multiplied by average revenue per user per month, which is accurate enough when plans are uniform and drifts once pricing gets varied. The more useful view breaks the month into new, expansion, contraction and churned MRR, because a flat total can hide heavy churn cancelling out heavy expansion.
What is the difference between MRR and revenue?
MRR is an operating measure of the subscription base at a point in time. Statutory revenue in your accounts is governed by accounting recognition rules, which decide when revenue is earned rather than when it is contracted or billed. Annual prepayments, mid-term upgrades and usage tiers all widen the gap. The two numbers are both correct and are not meant to agree.
Who should own MRR reporting in a startup?
Finance should own the definition, so the figure means the same thing every month regardless of who pulled it. Which finance hire depends on the job you need done. A financial controller will make the reporting consistent and controlled. A Head of Finance or CFO is the broader hire, covering modelling, budgeting and forecasting, and is what you need when MRR has to drive a hiring plan or a raise.
