A contrarian, by-stage guide to what to measure when you don’t have a board to report to and a smaller dashboard would serve you better.
How to use this page. Find your current MRR. Read only that section. Ignore the rest until you graduate. The wrong metric at the wrong stage is worse than no metric at all. How we research.
If you go on Twitter and read SaaS-metrics threads, you’ll see the same dashboard repeated endlessly: MRR, ARR, NRR, GRR, CAC, LTV, payback period, magic number, Rule of 40, burn multiple. That dashboard is appropriate — for a $10M ARR company with a CFO, a marketing team, and a board.
You are a solo founder. You don’t have a board. You have, at most, two free hours per week to think about metrics, and probably less. The question for you is not “which industry-standard dashboard should I copy?” The question is “which 2–4 numbers, watched weekly, will tell me the right thing to work on next?”
The answer changes with stage. The metrics that matter at $500 MRR are not the metrics that matter at $50,000 MRR. We’re going to walk through three stages and tell you exactly what to track at each, then explain what to ignore.
At this stage, you don’t have churn data because you barely have customers. You don’t have CAC because you’re probably acquiring customers manually through cold outreach or community presence. You don’t have LTV because nobody’s been a customer long enough to compute it.
You have three things, and these are the only three you should be watching:
Signups per week tells you whether anyone is interested. If you’re getting fewer than 5 signups per week at this stage, you have a distribution problem, not a product problem. No amount of product polish fixes a distribution problem. Stop fixing the product and go talk to humans.
Activation rate is the percentage of signups who reach the moment your product is actually useful. You define what “useful” means — for a CRM, it might be “imported contacts.” For an analytics tool, “saw their first chart.” If your activation rate is below 30%, your onboarding is broken. If it’s above 70%, your product is well-onboarded but you might be filtering out interested users earlier than you should.
Paying conversion is the percentage of signups who eventually pay. Below 3%, your offer isn’t resonating with the audience you’re reaching. Above 25%, you’re probably underpriced — review our pricing playbook and consider raising. The sweet spot is 5–15%.
Track these in a spreadsheet. Genuinely. You don’t need a tool. You need 5 cells updated every Friday. Adding more analytics infrastructure at this stage is a procrastination behavior, not a productivity behavior.
Once you cross $1K MRR, you have enough customers that statistical patterns start to show up. This is where most solo founders make their first metric mistake: they jump straight to MRR and call it good. MRR alone hides too much. Here are the three you actually need.
MRR is your total monthly recurring revenue. Net new MRR is new MRR added this month minus MRR lost to churn and downgrades. The reason to track both is that growing MRR can hide an MRR problem. If you added $1,000 in new MRR this month but lost $800 to churn, your business added $200 of value, not $1,000.
If your net new MRR is consistently below 30% of your gross new MRR, your churn is eating your growth. That’s a retention problem disguised as a growth problem.
Monthly churn is the percentage of paying customers who cancel each month. The benchmarks for healthy SaaS that get repeated everywhere — 1–2% monthly churn for B2B, 5–7% for B2C — are roughly correct, but here’s the distinction that matters at indie scale: voluntary churn (customers who actively cancel) is a product/value signal, while involuntary churn (failed payments) is a billing problem.
Most solo founders conflate these and waste time fixing the wrong one. If your involuntary churn is high, the fix is dunning emails and a smarter retry schedule — both Stripe and modern billing platforms handle this if you turn it on. If your voluntary churn is high, the fix is your product. Read your cancellation reasons. Talk to the people who left.
This is the median time from signup to the moment a user does the thing your product is for. For a CRM, the time from signup to importing contacts. For a scheduling tool, the time from signup to booking the first meeting.
Why this matters: time-to-first-value is the single best leading indicator of activation. Customers who reach value fast retain. Customers who don’t, churn. If your time-to-first-value is more than 24 hours for a B2B SaaS or more than 5 minutes for a B2C SaaS, your onboarding is the highest-leverage thing you can fix.
At $10K MRR, you have enough revenue and enough customers that the questions change. You’re no longer asking “is this thing working?” You’re asking “is this thing scalable, and where do I invest my next dollar?”
This is where unit economics become real, and where you should add three new numbers to your dashboard.
NRR is the percentage of last year’s revenue you still have from the same customers this year, including expansion. NRR above 100% means your existing customers grew their spend with you faster than other customers churned out. This is the holy grail of SaaS economics — it means you can grow without acquiring a single new customer.
For solo founders, NRR is harder to engineer than for venture-backed SaaS because you don’t have an account-management team running expansion plays. The simplest way to influence NRR at indie scale is to design your tier structure so that customer success organically pushes them into higher tiers. Per-seat pricing does this. Usage-metered pricing does this. Flat single-tier pricing does not.
Payback period is how many months of revenue from a new customer it takes to cover the cost of acquiring them. The math: customer acquisition cost / monthly revenue per customer. A 6-month payback period is excellent. 12 months is fine. 18+ months means you’re burning cash on growth in a way that doesn’t make sense for a self-funded solo operation.
Most solo founders ignore payback because they’re not running paid ads. But payback applies to organic acquisition too. If you’re writing one blog post per week and that takes 4 hours, those hours are your acquisition cost. Compute it. The answer is sometimes uncomfortable.
Aggregate CAC is misleading because it averages across channels with completely different economics. The CAC of a customer who came through SEO is approximately zero (after the content is published). The CAC of a customer who came through a paid ad is whatever you paid for that ad, plus your time.
By breaking CAC out by channel, you can see which channels are actually working. The trap: solo founders almost always over-invest in the channels that feel productive (Twitter, content) and under-invest in the channels that work but are uncomfortable (cold outreach, paid ads to a tight audience). Numbers help you see past the comfort gradient.
The metrics below feel productive to track but rarely change what you should do next. If you’re tracking them weekly, replace them with the stage-appropriate metrics above.
The test for whether a metric matters: if it changed by 50% next week, would you change what you’re working on? If not, you’re tracking it for reassurance, not decision-making.
Here’s the actual implementation. You can do this in one sitting.
Step 1: Install PostHog on the free tier. Add their JavaScript snippet to your app. PostHog gives you signups, activation events, and funnel tracking without a credit card up to 1 million events per month, which is far more than a solo SaaS needs at any reasonable stage. The full installation is one script tag and a few posthog.capture() calls.
Step 2: Set up one Stripe webhook. Listen for customer.subscription.created, customer.subscription.updated, and customer.subscription.deleted. Push these events to PostHog (or to a simple Google Sheet if you prefer). This gives you MRR, churn, and net new MRR for free. Stripe’s own dashboard also surfaces most of this without writing any code — the webhook is for combining payment data with product analytics in one place.
Step 3: Define your activation event. Pick the one action that defines “this user got value.” Track it in PostHog. Build a funnel from signup to activation. Now you have time-to-first-value and activation rate.
Step 4: Block 30 minutes every Friday for review. Open your dashboard. Look at the 3 numbers for your stage. Write down one observation. Decide one thing to work on next week based on what you saw.
That’s the entire system. It takes 30 minutes once and 30 minutes per week thereafter. It will outperform any 47-metric dashboard you set up because you’ll actually look at it.
Cohort analysis — tracking what happened to all the customers who signed up in March vs. April vs. May — is the highest-value metric most solo founders are not running. It’s also overkill before $10K MRR because you don’t have enough customers per cohort for the data to be meaningful.
Once you cross $10K MRR, run a monthly cohort retention chart. PostHog does this in three clicks. The pattern you’re looking for: each new cohort retains better than the previous one. If that’s happening, your product is improving faster than you’re acquiring customers, and growth is sustainable. If cohorts are getting worse, you’re acquiring lower-quality customers as you scale — which is a problem to address before you spend any more on acquisition.
The actual practice that separates solo founders who use metrics from solo founders who collect them is the weekly review. Block 30 minutes. Same time every week. Phone off.
Look at your numbers. Ask three questions:
Write the answers in a doc. Keep the doc. Reread it monthly. The pattern of what you’ve been paying attention to and what you’ve been doing about it is, over time, the strategy of your business. If you can’t see a pattern when you reread, that’s a signal to focus more.
If you’re self-funded and intend to stay that way, you can ignore most of the metrics that show up in pitch decks. Rule of 40 (growth rate plus profit margin) is a useful concept but mostly relevant for companies optimizing for valuation. Burn multiple is irrelevant if you’re not burning. Magic number is a sales-efficiency metric for companies with a sales team.
If you’re considering raising money or selling the business at some point, then yes, learn the language. But that’s a different exercise from running the business day-to-day. Most solo founders who track every investor metric do so as a way to feel like “a real company.” They are real companies. They just don’t need to act like growth-stage ones.
Pair the metrics in this guide with the rest of the operating playbook — your tech stack, your billing setup, and the kinds of products that work at this scale (see the real micro-SaaS examples we track).
At $0–1K MRR, watch signups per week, activation rate, and paying conversion. At $1K–10K, add MRR with net new MRR, monthly churn, and time-to-first-value. At $10K+, add NRR, payback period, and CAC by channel.
Skip the metrics that don’t change behavior. Run the 30-minute weekly review. Keep the dashboard small enough that you actually look at it. The biggest mistake in solo SaaS metrics is not the wrong metric — it’s having so many metrics you stop checking any of them.
