Hey {{first_name}} 👋, hope you had a great week! In the last issue, we discussed why tracking Cash inflows and outflows matter, and now we are moving with the next topic from Financial Metrics content.

Let’s talk about ⬇️

Most SaaS founders think they know how much runway they have.

They look at the bank balance, do some quick mental math, and move on.

But here's what that back-of-napkin calculation almost always misses: your burn rate today is not your burn rate tomorrow. Headcount is growing. Software contracts are renewing. A bonus payout is coming that your P&L has been quietly accruing for months.

By the time the spreadsheet catches up, the runway is already shorter than you thought.

So today, I want to walk you through 4 reasons cash runway visibility is non-negotiable for SaaS founders — and exactly how to track it with confidence.

Let's dig in:

1️⃣ It Tells You How Much Time You Actually Have

2️⃣ It Exposes Inefficiencies Before They Become Emergencies

3️⃣ It Builds Investor Confidence — Even Between Rounds

4️⃣ It Tells You When to Invest More Aggressively

The goal here is simple: know the clock before it runs out.

Cash runway measures how many months your current cash balance will last at your current burn rate. The formula is straightforward — total cash divided by average monthly net burn.

Here's a quick example: a company with $20M in the bank and a $750K average monthly net burn has roughly 26 months of runway.

But the benchmark matters too. A few years ago, 15–18 months post-fundraise was considered acceptable. Today, in a tighter market, investors view 25+ months as best-in-class. If you're sitting below that, fundraising conversations need to start earlier than you think.

Runway doesn't just tell you how long you have — it tells you how much time you have to hit the milestones that make your next raise possible. That's a very different, and much more useful, question.

The goal here is to catch problems while you still have options.

If your net burn is accelerating month over month, something is off. Maybe headcount is growing faster than revenue. Maybe a one-time expense got recurring treatment in the budget. Maybe sales and marketing spend ramped without a corresponding pipeline improvement.

Tracking runway regularly forces you to look at the underlying spend patterns — not just the headline number. And the earlier you spot an inefficiency, the more room you have to course-correct without making painful cuts.

A company that reviews runway monthly can trim strategically. A company that ignores it until the number is alarming is forced to make reactive, high-stakes decisions under pressure.

The goal here is to show investors you're in control of your capital, not just spending it.

Runway is one of the first things a sophisticated investor looks at. A longer runway signals that you have time to iterate, test, and grow without desperation driving your decisions.

More importantly, it signals that your finance function is sharp. Founders who can speak fluently about their burn rate, their runway trend, and how they're managing cash are far more fundable than those who have to go look it up.

In a market where investors are scrutinizing fundamentals more than ever, runway visibility isn't just a finance exercise — it's a fundraising strategy.

The goal here is to help you distinguish between burning with purpose and burning carelessly.

If your runway is sitting at 35–40 months, you're above best-in-class range. That's not necessarily a badge of honor — it might actually mean you're being too conservative. There could be deliberate investments you're not making in hiring, product development, or customer acquisition that would accelerate growth.

Runway visibility cuts both ways. Yes, it warns you when things are getting tight. But it also gives you the confidence to lean in when the numbers support it.

The rule of thumb: every meaningful cash outflow should be tied to a measurable growth outcome. If you can draw a straight line from the investment to ARR impact, the burn is working. If you can't, it probably isn't.

Most companies calculate runway using historical averages. Last month's burn, last quarter's spend — static data fed into a static model.

The problem is that your business isn't static.

You might be planning a new hire. A major software contract is up for renewal. A customer in your pipeline is close to signing, but collections won't hit for another 45 days. None of that shows up in a backward-looking spreadsheet — and all of it affects your true runway.

What actually works: dynamic, forward-looking forecasts that integrate your ERP, payroll platform, and CRM data in real time. Modern FP&A tools can model what-if scenarios — what does runway look like if we hire two engineers next quarter? What if that enterprise deal closes in 30 days vs. 90? — so decisions are grounded in current reality, not last month's assumptions.

In fast-moving environments, runway is constantly shifting. The founders who stay ahead of it aren't just tracking spend. They're anticipating what's next.

That's the framework. Hope it gives you a clearer picture of where your runway actually stands — and what to do about it.

Hit reply and tell me: are you calculating runway off historical burn or forward-looking projections? I read every response, and I'd love to know how your team is approaching it.
