Imagine this: A Ghent-based founder is in a pivotal fundraising meeting, proudly reporting her startup’s Monthly Recurring Revenue (MRR). She declares an MRR of €100,000 – a number that was meant to impress. But within minutes, the meeting goes off track. The savvy investor starts unpacking the figure and finds that the founder included one-time consultancy fees, forgot to account for hefty discounts given to early customers, and even counted “committed” MRR from a big client that only gave a verbal agreement. The investor’s smile fades. A debate ensues over what the real MRR is, eroding trust in the financials. Needless to say, the funding discussion derailed.
This anecdote (a composite of real stories) highlights how easily confusion around MRR can undermine credibility. So let’s clarify what MRR and its annual counterpart ARR really mean, how to calculate them properly, and why getting them right is crucial – especially for founders gearing up for growth and fundraising.
What are MRR and ARR, really?
Monthly Recurring Revenue (MRR) is the lifeblood of a subscription-based startup. It measures the predictable revenue you generate every month from ongoing subscriptions or contracts. In other words, it’s the sum of all recurring income, normalized to a monthly rate. Crucially, “recurring” means it excludes any one-off or irregular revenue. If you charge a customer €100 per month for your SaaS product, that’s €100 MRR. Ten such customers equal €1,000 MRR. If another upgrades or downgrades their plan, MRR adjusts accordingly. MRR is like your company’s revenue heartbeat – a consistent pulse that tells you if you’re growing, flat, or declining month to month.
Annual Recurring Revenue (ARR) is simply the normalised annual run-rate of your recurring revenue. It’s just MRR multiplied by 12. If your MRR is €10k, your ARR would be €120k. This is a forward-looking projection of what you’ll earn in a year, assuming no changes in your subscriptions. It gives a big-picture view of your revenue scale. Many investors and stakeholders like talking in ARR terms (it sounds bigger and is handy for valuations), but remember: ARR is a result of current MRR, not a guarantee of future revenue. If your MRR drops next month, ARR will drop too.
A quick sanity check: If someone claims €1M ARR, that implies about €83k MRR at that moment. The two metrics are interchangeable in that way (ARR is just a year’s worth of MRR). So avoid double-counting them or treating ARR as something more mystical – it’s not a forecast, just a math conversion.
MRR today, revenue tomorrow
MRR is a snapshot of your recurring revenue today, but it’s also a baseline for the future. If nothing changes – no new sales, no customers leaving or upgrading – your current MRR will repeat next month, and the month after, and so on. In that sense, MRR is forward-looking: it predicts future revenue stability if all else remains equal. For example, if you’re at €50K MRR now, you can expect roughly €50K next month too (assuming no churn or new deals), which would be about €600K over the next 12 months. This is what makes recurring revenue so powerful – it provides visibility into future income.
Of course, in reality things do change: customers churn, some upgrade or downgrade, and hopefully you sign up new ones. But using MRR as a starting point, you can project scenarios. Many SaaS companies even track a metric called Committed Monthly Recurring Revenue (CMRR) or Signed or Booked MRR – basically current MRR plus signed contracts that will start soon (and minus any known cancellations). This gives a forward-looking sense of what next month’s MRR will be. It’s useful for internal planning, but investors treat “committed” revenue with caution. A signed deal that isn’t live yet isn’t money in the bank; the customer could delay or cancel. So, you might mention “we have €5K in committed MRR starting next quarter,” but most VCs will focus on your current MRR and perhaps count committed revenue separately (or heavily discounted) in their assessment.
Counting MRR correctly (no fudge factor)
Calculating MRR is straightforward, but you need to do it consistently and link it to your invoicing. Here are some guidelines:
- Exclude one-time revenues: If you did €10k in professional service fees or a one-off hardware sale this month, that’s great but it’s not recurring revenue. It doesn’t belong in MRR. Investors typically only care about recurring revenue when evaluating MRR/ARR because it indicates sustainable income.
- Use actual prices (after discounts): If your customer is paying €50 per month after a 50% discount on a €100 plan, your MRR from that customer is €50, not €100. Reporting the pre-discount price would inflate MRR and mislead. Always use the invoiced amount.
- Align with invoicing and terms: Suppose a client pays €12,000 upfront for an annual subscription. You should recognize that as €1,000 MRR over 12 months, not €12k all in the month of payment. MRR spreads annual deals into monthly increments so that your revenue tracking stays smooth. Similarly, if a customer commits to start a €2k/month subscription next quarter, that future revenue is committed MRR – you might note it in conversation, but it’s not live MRR until it’s officially begun (and ideally invoiced).
- Stay consistent: Decide on a methodology (most SaaS companies follow the above conventions) and stick to it. This consistency builds trust. If an investor digs into your numbers, they should find that your MRR is simply the sum of all active subscriptions’ monthly values, no more, no less.
By calculating MRR correctly, you avoid unpleasant surprises in due diligence. You’re showing a clear picture of your recurring revenue engine, which is exactly what investors want to see.
A pro tip from SaaS veterans: don’t just look at your topline MRR or ARR in aggregate – break it down by meaningful segments. Segmenting your recurring revenue can uncover insights that average totals mask. For example, you might segment MRR by product line, by customer type (e.g. SMB vs Enterprise clients), or by geography (domestic EU market vs US customers). Seasoned SaaS CFOs and growth experts often do this to get different lenses on the business. By analyzing segment-level MRR, you can answer critical questions: Is our new product module growing faster than our core offering? Are enterprise clients contributing disproportionately to our growth? Is our expansion in the UK outpacing the rest of Europe? Just as public SaaS companies report revenue by product or region to highlight growth drivers, startups too can benefit from this practice. One European SaaS investor notes that tracking the key movements in MRR – new sales, upsells, downgrades, cancellations, reactivations – early on lets you see what’s happening in each customer segment or region and where to focus to grow. In other words, by segmenting MRR, you might discover that Product A is a superstar fueling 70% of new MRR, or that churn is mostly coming from SMB customers in a particular region. These insights allow you to tailor your go-to-market strategy – maybe double down on the promising segment and retool your approach in weaker ones. The result is a more data-informed strategy, ensuring you’re not flying blind on just a headline number.
Breaking down MRR movements (new, expansion, contraction, churn)
Understanding MRR movement means looking at how your monthly recurring revenue changes due to different factors. The key components that drive MRR up or down are new MRR, expansion MRR, contraction MRR, and churn MRR. Below are founder-friendly definitions for each, along with how to calculate them in basic terms:
New MRR: This is the recurring revenue added from brand new customers acquired during the month. To calculate new MRR, sum up all the subscription revenue from newly added accounts in that period. For example, if you onboard 5 new customers each paying €100 per month, that’s €500 in New MRR added for the month.
Expansion MRR: Expansion MRR is additional recurring revenue gained from existing customers when they upgrade or purchase add-ons in a given month. In practice, you calculate it by adding up all the extra monthly revenue from current customers expanding their subscriptions during that month (e.g. moving to a higher-priced plan or adding extra seats/features). For instance, if a customer on a €100 plan upgrades to a €150 plan, the €50 increase is counted as expansion MRR.
Contraction MRR: Contraction MRR represents the recurring revenue lost when existing customers downgrade or reduce their subscriptions (the opposite of expansion). Unlike churn, these customers remain with you but pay less – you haven’t lost the customer, just some of their revenue. To calculate contraction MRR, sum up all the monthly revenue that was subtracted due to downgrades or plan reductions in that period. For example, if a client downgrades from a €100/month plan to a €70/month plan, the €30 decrease would be counted as contraction MRR for that month.
Churn MRR: Churn MRR is the amount of recurring revenue lost due to customers canceling (churning out) their subscriptions in the month. You calculate it by adding together all the MRR from the subscriptions that ended during that period. For example, if two customers paying €200 each per month cancel, that’s €400 of churn MRR in that month (revenue gone due to churn).
Each of these components helps explain why your MRR changed. In essence: new MRR and expansion MRR contribute to growth, while contraction MRR and churn MRR represent revenue declines. By tracking these separately, you can clearly see how much of your MRR increase came from new sales or upsells, and how much of any decrease was due to downgrades or lost customers. This sets the stage for computing Net New MRR (New + Expansion minus Churn + Contraction) and gives you a granular view of your subscription revenue’s health. Remember, the goal is consistent positive MRR growth, so ideally your New and Expansion MRR outweigh any losses from Contraction and Churn in each period.
Benchmarks by stage in Europe: What’s “Good” MRR/ARR?
Founders often ask: How much MRR should we have at pre-seed/seed/Series A? The reality is, it varies widely. Europe’s funding environment has its own norms and they evolve over time. As one VC put it, “MRR isn’t a one-size-fits-all investment metric” – there isn’t a magic number that guarantees a successful raise. A pre-seed startup with no revenue but a waitlist and strong pilot customers might still attract investment if other factors (market, team, growth signals) are strong. Conversely, a startup with €100k MRR could struggle if growth is flat or churn is high. Revenue milestones alone don’t paint the full picture.
That said, here are some rough European benchmarks and expectations to provide context:
- Pre-Seed: Often pre-revenue or just a trickle of MRR. The focus here is proving customer interest, not hitting a revenue target. MRR might be anywhere from €0 into a few thousands. Growth can be lumpy at this stage. Investors are looking more at engagement or pilot feedback than revenue. Monthly growth could be very high percentage-wise (from €500 to €1,000 is 100% jump!) or essentially irrelevant if the product isn’t fully launched. Don’t stress – demonstrate traction in whatever form makes sense.
- Seed: By seed, having some revenue greatly bolsters the story. Many European seed-stage SaaS startups have somewhere in the low-to-mid five figures of MRR (e.g. €15k, €20k, €50k – wide range) if they’re post-launch. Hitting ~€15k MRR (€180k ARR) or more with solid month-on-month growth (say 10–20% MoM) is a strong signal, but not a hard rule. In fact, investors in seed rounds often care more about growth rate and a repeatable sales process than the absolute MRR. One global survey suggests seed-stage companies might be growing ~15–30% monthly at this phase – evidence that something is clicking with customers. If you’re smaller, you can compensate with a great story on how you’ll scale.
- Series A: Here the bar rises. Series A investors in Europe typically want to see significant traction and growth. It’s not unusual to aim for around €83k+ MRR by Series A, which is roughly €1m ARR. More important than any single number, Series A folks will look at your growth curve – often 10%+ month-over-month growth consistently, or in annual terms, doubling or tripling year-over-year. In recent years, a company growing ~3x annually (which is ~20% MoM sustained) on a few hundred thousand ARR is very attractive. Efficiency also starts to matter here: your revenue relative to burn, and metrics like customer acquisition cost payback. But fundamentally, MRR/ARR and its growth are the headline. Hitting, say, €1M ARR (≈€83k MRR) with strong momentum is a classic Series A story, though some get there earlier and some later.
(Note: These figures are illustrative – there are outliers. Don’t be discouraged if you’re below or think you need much more. Demonstrate a healthy growth trajectory, retention, and a big market, rather than obsessing over a specific MRR threshold)
For later stages (Series B, C, etc.), the expectations scale up (multiple millions in ARR and steady growth, plus other quality metrics).
Using MRR and ARR in strategy and planning
Getting MRR right isn’t just about impressing investors – it’s a daily tool for running your business. Here are a few ways these metrics inform strategy:
- Hiring and Expenses: Your recurring revenue sets the baseline for budgeting. Many founders plan hiring in step with MRR milestones – e.g. “When we hit €20k MRR, we can comfortably hire another developer without overextending.” Because MRR is predictable, it gives confidence in making commitments like new salaries. If MRR dips or growth stalls, that might be a signal to slow down hiring or trim costs.
- Marketing and Growth Investments: A steadily growing ARR can justify increasing your marketing spend. For example, if you see MRR climbing reliably 15% each month, you might reinvest more into customer acquisition, knowing that the recurring income will recoup those costs over time. On the flip side, if MRR growth is sluggish, it might prompt a review of your go-to-market strategy or marketing channels.
- Pricing and Product Decisions: Tracking MRR closely can reveal when it’s time to adjust pricing or packaging. If new MRR additions are low, maybe your pricing isn’t resonating or your product’s value proposition needs a boost. Conversely, strong expansion MRR (customers upgrading) indicates that users are willing to pay more for additional value – a green light to invest further in those areas. MRR is also useful in A/B testing pricing changes – you’ll see the impact in real revenue quickly.
- Churn Analysis: Breaking MRR into components helps identify problems. For instance, if you have €5k new MRR in a month but €4k of churned MRR from cancellations, your net gain is only €1k – a red flag. By monitoring churned MRR as a percent of total, you can catch if customer retention is worsening and react (improve support, target the right customer segment, etc.). Many founders track a waterfall of MRR – starting each month’s MRR, adding new and expansion MRR, subtracting churn – to visualize how revenue is evolving. This informs retention strategies and customer success efforts.
- Timing for Fundraising: Perhaps most strategically, MRR/ARR trends help you decide when to raise money. Plan your funding rounds to show a compelling MRR story. Investors will look at your ARR growth rate – for example, growing from €100k to €400k ARR in a year (4×) is a powerful narrative for a Series A. Use your MRR trajectory to argue that “we’ve found a repeatable model – with more capital, we can scale it.” Also, tracking runway in terms of MRR vs burn tells you how long you have to hit the next inflection point. Smart founders target a fundraise when they’ve hit a strong revenue milestone and still have a few months’ runway, rather than waiting until cash is almost gone.
Example: A chart of monthly MRR growth over a year, broken down by new MRR (green), expansion/up-sell MRR (blue), and churned MRR (red). The orange line shows total MRR. Visualizing MRR in this way can help you understand what’s driving your revenue changes each month (in this hypothetical case, steadily increasing new sales and some periodic upsells far outweigh the small churn).
Wrapping Up
For startup founders new to finance, MRR and ARR may seem like just more acronyms – but they’re fundamental gauges of your company’s health. Nail down their definitions and calculate them rigorously. In doing so, you’ll build credibility with investors and clarity for yourself. Remember the founder from our opening story: by cleaning up how you report MRR, you not only avoid a fundraising fiasco, you also gain a clearer view to steer your startup toward sustainable growth. MRR and ARR, done right, become two of your best allies – guiding decisions, rallying your team around growth goals, and telling a powerful story to those who might fund your journey.
