It starts the same way for almost everyone.
You launch. Your first paying customer signs up. You open a Google Sheet, type in $29, and label the column "MRR." You feel good about this. You have a system.
Three months later, the spreadsheet has 40 rows, half of them wrong. One customer churned and you forgot to remove them. Two annual subscribers are in there at their full price, not divided by 12. There's a #REF! error in row 23 that you've been ignoring since January.
Your MRR figure is somewhere between "roughly right" and "actively misleading."
This is the indie hacker spreadsheet lifecycle. It's not a failure of discipline — it's a failure of the system.
Why spreadsheets break
Spreadsheets require active maintenance from a person who is already stretched thin. Every time something changes — a new subscriber, a cancellation, a plan upgrade — the spreadsheet needs a human to update it.
The problem isn't that you're lazy. The problem is that you have twenty other things to do on the same day someone upgrades their plan, and updating a spreadsheet is at the bottom of the list.
Eventually the spreadsheet drifts from reality. You stop trusting it. You stop looking at it. You revert to "vibes-based MRR" — a number you think is approximately right but couldn't defend if someone asked you to.
The fix: pull from your payment processor
If you're charging customers through Stripe or Lemon Squeezy, the real number already exists. Your payment processor knows every active subscription, every plan interval, every charge.
The simplest upgrade from a broken spreadsheet is to stop maintaining your own copy and start reading from the source:
- Stripe: Revenue → MRR in the dashboard. It handles monthly and annual subscriptions, trials, and cancellations automatically.
- Lemon Squeezy: Analytics tab. MRR, new MRR, churn, at a glance.
This alone gets you 80% of the way there. You have a number. It updates automatically. You can trust it.
The missing piece: accountability
Here's what payment processor dashboards don't give you: a reason to care about the number consistently.
Private dashboards are private. Your Stripe revenue tab is a tab you open, look at, and close. Nobody else sees it. There's no external pressure to keep it accurate or to actually do something when the number goes down.
This is why building in public changes things.
When you put your MRR on a public profile — even a simple one — the number becomes a commitment. Other founders can see it. Your Twitter followers can see it. You can see how you compare to founders who started at the same time or the same MRR level.
That comparison isn't about competition. It's about context. Knowing you're at $800 MRR means something different when you can see that a founder who was at $800 MRR eighteen months ago is now at $12K MRR. It makes the trajectory feel real and achievable, not abstract.
What monthly recurring revenue actually measures
MRR is deceptively simple:
MRR = (active monthly subscribers × monthly price)
+ (active annual subscribers × annual price ÷ 12)
But the number earns its significance from what it implies: predictability. MRR is the revenue you can plan around. It tells you whether your business is growing, stalling, or quietly declining.
Indie hackers who track MRR consistently make better decisions — on pricing, on feature prioritization, on when to raise prices or when to invest in growth. The ones who rely on "vibes-based MRR" tend to be surprised by things that the data would have shown them months earlier.
The simplest system that actually works
- Let your payment processor calculate MRR — don't duplicate it in a spreadsheet
- Check it once a week — same day, same time, put it in your calendar
- Publish your number publicly — even just sharing monthly MRR updates on Twitter or posting to a public profile like mrr.fyi creates the accountability loop that keeps tracking consistent
- React to changes — MRR up? Find out why and do more of it. MRR down? Find the cancellation and understand the reason.
That's the whole system. No complex software, no paid tools, no dashboards with seventeen charts.
From tracking to growing
The founders who grow fastest aren't the ones with the best tracking tools. They're the ones who know their number and act on it consistently.
Public MRR tracking adds one more layer: community. When your monthly recurring revenue is visible to other indie hackers, you get reactions. People comment when you hit a milestone. They ask what's working when you have a big month. They offer suggestions when growth stalls.
That feedback loop — revenue data plus community response — is more valuable than any private analytics dashboard.
Track your MRR. Make it public. See what changes.
