The SaaS metrics investors actually ask for in 2026

In 2021, a SaaS pitch could be carried by one chart: ARR going up and to the right. That era is over. Growth still matters, but the questions have changed. Investors want to know how efficiently you grow, and how good the revenue you already have is.

I see this from both sides. I've built SaaS companies as a founder, and I'm an angel investor and board member in SaaS startups, so I read a lot of monthly updates. The founders who get the best conversations aren't the ones with the flashiest numbers. They're the ones whose numbers are consistent, clearly defined, and tell an honest story. Here are the metrics that come up in almost every conversation now.

1. ARR, and where it came from

ARR is still the headline. But a single number hides everything interesting, so show the movements: new, expansion, contraction and churn, every month. Two companies can both add $50k of net new ARR, one from a healthy base that expands and one by signing enough new customers to cover a growing churn number. Investors will ask which one you are. Show them before they ask. (If you need a refresher on the definitions, the academy covers ARR and MRR churn.)

2. NRR and GRR, side by side

Net revenue retention tells an investor whether your existing customers grow. Gross revenue retention tells them how much you keep before any expansion: the floor. High NRR with a weak GRR means a few customers are expanding a lot while many others leave, which is fragile. Show both, and be ready to show them by cohort.

3. The burn multiple

The burn multiple is net burn divided by net new ARR: how many dollars you burn to add one dollar of ARR. David Sacks at Craft Ventures introduced it in 2020, and it has become the efficiency question. It's simple, hard to game, and it connects your growth to your bank account.

4. CAC payback and the magic number

How long does it take to earn back what you spend acquiring a customer? CAC payback answers that in months, ideally on a gross margin basis. The magic number answers a similar question at the company level: how much new ARR each dollar of sales and marketing produces. Expect to be asked for both, and expect follow-up questions about which channels drive them.

5. The Rule of 40

Growth rate plus profit margin should add up to at least 40%. The Rule of 40 matters more as you get bigger. For an early-stage company it's more of a direction than a test, but knowing where you stand shows you understand the trade-off between growth and burn.

6. Customer concentration

If your top ten customers make up half of your revenue, losing one of them is a crisis. Investors will ask, especially at earlier stages where one large customer can dominate. Know your customer concentration and have a story about how it's trending.

7. Gross margin, including AI costs

This one is new. If your product uses AI models, your cost of serving each customer is no longer close to zero. Investors want to know your gross margin with inference costs included, and how it changes as customers use the AI features more. A product that loses margin as usage grows is a very different business from one that doesn't.

8. Runway, based on real cash

Revenue isn't cash. Annual plans, failed payments and invoice terms all make the two diverge. Show runway based on when money actually lands in your account, not on MRR, and know your cashflow well enough to explain the lumpy months.

What they care less about now

Some numbers that used to fill pitch decks get a polite nod at best. Total signups and registered users, without conversion to paid. "ARR run rate" built from one unusually good month, or from one-off services revenue. Growth percentages from a tiny base without absolute numbers next to them. Logos without revenue attached. None of these are wrong to mention, but none of them answer the two questions investors are really asking: is this revenue durable, and how much does it cost to add more of it? If a metric doesn't help answer one of those, it belongs in the appendix.

How to present it

The format matters less than the consistency. A few rules I wish every founder followed:

• Same definitions, every month. If you change how you calculate something, say so. Nothing destroys trust faster than a metric that quietly changes meaning.
• Show the movements, not just the totals. New, expansion, contraction and churn tell the story. The total alone hides it.
• Include the bad news. Investors know every company has a rough month. Hiding one is much worse than explaining it.
• Keep it to one page, with the details a click away for anyone who wants them.

Let the numbers come from one place

The hardest part of investor reporting isn't the presentation. It's getting numbers that are right and consistent every month, without rebuilding a spreadsheet each time. GrowPanel calculates ARR, the MRR movements, NRR, GRR and cohorts directly from your billing data, and the cashflow reports show when money actually lands. Every number is traceable back to the invoices behind it. Founders and CFOs use it to prepare for board meetings, and investors use it to follow their portfolio companies without waiting for the monthly update.
