How many customers do you need to hit €10k MRR: the table, and the churn that moves it
Almost every founder picks a revenue number before they pick a price. Ten thousand a month, because it sounds like escape velocity and because somebody on the internet hit it in public. Then they never divide it by anything. The division takes eleven seconds and it changes what you should build, what you should charge, and what you should do tomorrow morning.
Two numbers decide whether €10,000 a month is a plan or a wish. The first is your price, because it sets how many customers the target is made of. The second is your monthly churn rate, because it sets how many of them walk out of the back door while you are letting new ones in the front. Everything else on this page is those two numbers pushed around.
The table everybody actually wants
Read the second column first, then read the fourth one, because the gap between them is the part that goes missing in every "just get 1,000 true fans" post ever written. Column two is the base you have to be holding. Column four is what you have to sign every month, forever, just to still be holding it next month.
| Price a month | Customers to hold €10,000 MRR | Median monthly churn at that price | New customers a month just to stand still | New customers a month to get there in 24 months |
|---|---|---|---|---|
| €5 | 2,000 | 6% | 120 a month | 155 a month |
| €9 | 1,112 | 6% | 67 a month | 86 a month |
| €15 | 667 | 6% | 40 a month | 52 a month |
| €19 | 527 | 6% | 32 a month | 41 a month |
| €29 | 345 | 4% | 14 a month | 22 a month |
| €49 | 205 | 4% | 8 a month | 13 a month |
| €99 | 102 | 3% | 3 a month | 6 a month |
| €199 | 51 | 3% | 1.5 a month | 3 a month |
| €499 | 21 | 3% | 0.6 a month | 1.2 a month |
Look at the €19 row and the €99 row together. Both are ordinary prices for an ordinary tool. One asks you to hold 527 customers and hand over 32 fresh ones every month for the rest of the product's life. The other asks for 102 customers and 3 replacements. Same revenue, and one of those jobs is ten times the other one.
Why 10,000 divided by your price is the wrong number
The naive division treats customers like bricks. Stack 527 of them and the wall is built. Customers are not bricks, they are water in a bucket with a hole in it, and the hole is proportional to how much water is already in there. At 6% monthly churn a base of 100 loses 6 a month and a base of 500 loses 30. The bigger you get, the harder the standing still.
- Customers to hold €10,000 MRR = 10,000 ÷ your monthly price The snapshot. This is the number everybody stops at.
- New customers a month to stand still = that number × your monthly churn The treadmill. Sign fewer than this and the base shrinks.
- The most customers you will ever hold = new customers a month ÷ monthly churn The ceiling. This one decides whether the target is reachable at all.
The third line is the one worth writing on something. If you sign a steady 10 customers a month and lose 6% of your base a month, your base settles at 167 customers and stops. Not slows down. Stops. Month 30 looks like month 60. At €19 that is €3,167 a month, and no amount of persistence at 10 a month moves it, because at 167 customers the 10 you sign and the 10 you lose cancel exactly.
Here is that ceiling as a grid. Every cell is the MRR you settle at, forever, on a €19 product, given a steady acquisition rate down the side and a monthly churn rate across the top. Find your row, find your column, and that is the business you have built unless you change one of the two inputs.
| New customers a month | 2% churn | 4% churn | 6% churn | 8% churn |
|---|---|---|---|---|
| 5 a month | €4,750 | €2,375 | €1,583 | €1,188 |
| 10 a month | €9,500 | €4,750 | €3,167 | €2,375 |
| 20 a month | €19,000 | €9,500 | €6,333 | €4,750 |
| 40 a month | €38,000 | €19,000 | €12,667 | €9,500 |
That last point is the practical one. Founders treat churn as weather and acquisition as work. The grid says they are the same lever pulled from opposite ends. Going from 8% to 4% churn doubles your ceiling, and it is often three onboarding emails and one better first session, which is a smaller job than doubling your output for a year.
The funnel above the customer count
Column five of the first table gives you a monthly number. It is still too abstract to act on, because nobody wakes up and does thirteen customers. What you can do is a volume of something, and the conversion rates between that volume and a customer are where the plan either survives or quietly falls apart.
Take €49 a month, so 205 customers and 13 new ones a month to arrive inside two years. Run all four of the Core 4 lanes at the volume one person can genuinely sustain in a morning, and see what a month produces.
| Lane | One month at full daily volume | The rate you can defend | New customers |
|---|---|---|---|
| Warm outreach | Ten asks a morning, 220 in a month | Roughly one ask in ten turns into a customer | 22, once |
| Posting in public | One post a morning, 22 in a month | Nothing traceable before post 30, then about eight inbound conversations a month closing near 20% | 2 a month, from month three |
| Cold outreach | Forty sends a morning, 880 in a month | About 0.6% of sends become a paying customer | 5 a month |
| Paid | €500 of spend a month | About €150 to acquire one customer at this price, once the creative is not terrible | 3 a month |
Add it up honestly. Month one gives you 22 from the warm list. Every month after that gives you about 10, and that is with four lanes running properly rather than the two most founders actually keep up. Against a target of 13 a month you are short, and short compounds against you. Feed 10 a month into a base leaking 4% and the ceiling is 250 customers, so €10,000 at €49 sits at 82% of everything that rate will ever build. You get to 205 customers somewhere around month 40.
Now run the same 10 a month against a €99 price. You need 102 customers, you need 6 a month to be there in eighteen months, and your ceiling at 3% churn is 333 customers. The target is no longer near the asymptote, so the last stretch does not eat two years. Identical effort, identical daily volumes, and the finish line moves from month 40 to month 18 because of one decision made on the pricing page.
Divide 10 a month by the days you will actually work and you get the number that matters on a Tuesday, which is somewhere near one meaningful action a morning and about half a customer a week. That is the whole point of running this arithmetic: a goal you cannot act on becomes a volume you can. The 100 in 100 calculator does the same division against working days rather than calendar days, and the daily marketing routine is what that volume looks like as an actual morning.
Annual billing moves the number the wrong way
Somebody will tell you to push annual plans, and they are usually right, but not for the reason they give. MRR from an annual plan is the annual price divided by twelve, on the day it starts and every month after. Sell a €190 annual plan instead of a €19 monthly one and you took €190 of cash and added €15.83 of MRR. Your cash position improved and your progress towards €10,000 got slower.
| Plan | Cash on signup | MRR it adds | Customers for €10,000 MRR | Effective monthly churn |
|---|---|---|---|---|
| Monthly, €19 | €19 now | €19.00 | 527 | 6% a month |
| Annual, €190 (two months free) | €190 now | €15.83 | 632 | 2.9% a month if 70% renew |
| Annual, €199 | €199 now | €16.58 | 604 | 2.9% a month if 70% renew |
| Annual, €228 (no discount) | €228 now | €19.00 | 527 | 2.9% a month if 70% renew |
Weigh the two effects against each other before you decide. The discounted annual plan needs 105 more customers for the same headline, and it replaces about 18 a month instead of 32. You are buying a much smaller treadmill with a slightly longer track. For a solo founder that trade is usually worth taking, because the treadmill is the thing that kills people and the extra 105 customers is just more of the same work.
Two rules keep the reporting honest. Count annual revenue as the annual price over twelve, always, including in the screenshot you post on launch day. And keep the cash number separately, because an annual plan that pays for eleven months of hosting up front is a real thing that happened to your bank account, and pretending otherwise is its own kind of dishonesty.
The honest read on each price band
Here is where the arithmetic stops being neutral. Some of these price points describe a business one person can build in their mornings. Some describe a business with a sales process and a support rota attached, and some describe a business that needs a media budget before the first customer. The tables above do not tell you which one you are in. This does.
There is a version of this page that ends with encouragement. This is not it, because the most useful thing the arithmetic does is tell some people to stop planning a hundred days of outreach and go and change a number on their pricing page instead. If you are at €9 and you want €10,000, no channel decision in the ranked list of channels gets you there. You are looking at 1,112 customers and 67 replacements a month, and the honest fix is upstream of everything marketing can do.
What to do with the number tomorrow
Four things, in this order, and all four fit in one session. The point of doing them today is that the answer stops being a feeling about whether you are behind and becomes a number you can check on a Friday.
- Do the division out loud. Your price into 10,000, rounded up. Say the number. 527 lands differently than "ten grand a month" does, and it should, because it is the same fact with the flattery removed.
- Measure your actual churn before you assume a benchmark. Cancellations this month divided by customers at the start of the month. If you have fewer than 30 customers the number is noise, so use 6% and re-measure at 50. Everything in the ceiling grid hangs off this one figure, so a guess here makes the whole plan decorative.
- Find your ceiling. New customers in a normal month, divided by your churn rate, times your price. If that number is below your target, more effort is not the fix and no amount of consistency will make it the fix. Change the price or fix the leak, then come back.
- Convert the monthly number into a daily volume. Not "get 13 customers". Ten warm asks, or forty cold sends, or one post, tomorrow at the same time as today. The gap between a founder at €400 MRR and one at €4,000 is usually not the plan, it is the number of mornings, which is the argument in the Rule of 100.
One caveat before you go and reprice everything. The arithmetic on this page assumes the price is a number you can move, and for a product with 30 customers it usually is. It also assumes the target is worth having in the first place, and €10,000 a month is a nice round number rather than a fact about your life. Divide the number you actually need instead. For a lot of solo founders that is €3,000, which at €49 is 62 customers and four replacements a month, and that is a completely different hundred days.
Then start signing them. The first hundred customers is the playbook for the part that comes after the division, the warm outreach templates cover the twenty-two you can get in month one, and the cold versus content comparison settles which lane fills the months after that. And if the last three attempts stalled around week four rather than around the arithmetic, the quitting problem is a better use of your evening than another spreadsheet.
Questions founders actually ask
- How many customers do I need to reach €10k MRR?
- Divide 10,000 by your monthly price and round up. At €5 that is 2,000 customers, at €9 it is 1,112, at €19 it is 527, at €29 it is 345, at €49 it is 205, at €99 it is 102, at €199 it is 51 and at €499 it is 21. That is the number you have to be holding at once. The number you have to sign is larger, because a share of the base cancels every month and has to be replaced before any of your work counts as growth.
- How many customers do I need at €49 a month to make €10,000 a month?
- 205 customers, and about 8 replacements a month on top of that to hold the line, using the 4% median monthly churn ChartMogul reports for the $25 to $100 ARPA band. To get from zero to 205 inside 24 months you need to sign 13 new customers every month for two years without a gap. To get there inside 40 months you need 10 a month, which is roughly what four distribution lanes run daily produce for one person.
- Why is 10,000 divided by my price the wrong answer?
- Because it is a snapshot of a base that is leaking. At x% monthly churn you lose x% of your customers every month, so holding N customers requires signing N times x every month before you grow by one. The consequence people miss is that a fixed acquisition rate has a hard ceiling: the largest base you will ever hold is your new customers a month divided by your monthly churn rate. Ten new customers a month at 6% churn tops out at 167 customers, no matter how many years you run it.
- How long does it take a solo founder to reach €10k MRR?
- At €99 a month and 3% churn it takes about eighteen months of six new customers a month. At €49 and 4% churn it takes about 40 months at ten new customers a month, because €10,000 sits at 82% of the ceiling that rate implies, and the last stretch of an asymptote is where the years disappear. At €19 and 6% churn, ten new customers a month never gets there at all. The price moves this answer far more than effort does.
- What is a normal monthly churn rate for an early-stage SaaS?
- ChartMogul, working from over 2,500 SaaS businesses, puts median monthly customer churn at 6.5% for companies under $300k ARR and 3.7% for companies between $1m and $3m. Split by price, the median is 6.1% for an ARPA under $25 a month, 4.2% between $25 and $100, 3.1% between $100 and $250, and 1.8% above $1,000. Cheap products churn about three times as fast as expensive ones, which is the fact that decides most of the arithmetic on this page.
- Does annual billing help me reach €10k MRR faster?
- It helps your bank balance and it hurts the headline number. A €190 annual plan sold instead of a €19 monthly plan contributes €15.83 of MRR rather than €19, so the same €10,000 target now needs 632 customers instead of 527. What you buy for those extra 105 customers is a base that only decides once a year instead of twelve times, which at a 70% renewal rate works out at about 2.9% effective monthly churn. You need 20% more customers and you have to replace about half as many of them.
- Is it easier to get 100 customers at €99 or 1,000 customers at €9?
- 100 at €99, and it is not close. The 1,000-customer version needs 60 replacements a month at the 6% churn typical of cheap products, against 3 a month for the 100-customer version. Twenty times the acquisition workload for the same revenue. The €99 version needs a better product and a sharper buyer, and it needs you to say a bigger number out loud on a call, which is the real reason most founders pick the harder column.
