"Wait, You Want Me to Do *Math*?"

I've been a CRO for twenty-five years, and I still remember the call that made me write this answer.

It was a Tuesday. I was on the phone with a healthcare SaaS founder—$6M ARR, great product, terrified of hiring. He had a board meeting in two weeks and needed to know: *"How many reps do I hire to get to $10M?"* His VP of Sales had already hired three people. The founder had no idea if that was right.

I told him the same thing I'm telling you: you don't guess headcount. You back into it from the gap.

The Formula That Saves You From Your Gut

Here's the math that keeps me up at night—but in a good way:

Reps to hire = (net-new ARR you need / new ARR one ramped AE produces per year) + backfills for attrition, adjusted for ramp time.

Sounds like a board deck, right? Let me walk you through it with real numbers.

Say you're at $6M ARR, you want $10M, and you're running 112% NRR. Your existing base carries itself to about $6.7M. That leaves roughly $3.3M of net-new you need your AEs to sell.

Now, a fully ramped healthcare AE—someone who's been through six to nine months of learning clinical workflows and hospital procurement—produces about $550K of new ARR per year at realistic attainment. That's 6 rep-years of capacity.

But here's where it gets painful: that healthcare AE you hire today? They're not productive for the first six to nine months. Long buying committees, compliance reviews, pilot programs. And you'll lose about 20% of your team to attrition annually.

So net it out: you're not hiring six reps. You're hiring 8 to 10 AEs, and you need to start them early enough that they ramp *before* you need the production.

The Tools That Do This Without a Spreadsheet From Hell

I've used every tool on this list. Some saved me. Some... Let's just say I learned what *not* to do.

1. PULSE Recruiting Calculator 🏆 BEST OVERALL

This is the one I wish I'd had fifteen years ago. It's free, it's browser-based, and it runs the entire capacity model in seconds. You type in your current and goal ARR, your NRR (current and goal), your productive capacity per AE, ramp time, training length, attrition, and current headcount—and it spits out how many reps to hire and when they need to start.

No login. No spreadsheet. Just a defensible headcount plan.

Best for: healthcare SaaS founders, CROs, and RevOps leaders who want to stop guessing.

2. Salesforce (with capacity planning)

If you're already on Salesforce (most healthcare SaaS teams are), you can build a capacity model on top of your data. Pricing runs from about $25 per user per month (Starter) to $165-plus (Enterprise). It won't hand you a hire number out of the box, but it has the actuals—attainment, ramp, attrition—that the calculation needs.

3. HubSpot Sales Hub

From about $20 per seat per month up to enterprise tiers. Great for mid-market teams already on HubSpot. Like Salesforce, it gives you the data to build the model, not the model itself.

4. QuotaPath

Ties quota, attainment, and commissions together. Free tier available, paid plans from around $15 per user per month. It grounds your per-rep capacity figure in reality—especially valuable when one big hospital deal can swing a rep's entire year.

5. Pigment

A modern business-planning platform. Typically four to five figures a year. Models headcount, capacity, ramp, and quota coverage with live scenarios. For scaling healthcare SaaS companies past the spreadsheet stage.

6. Cube

Spreadsheet-native FP&A platform, typically from around $1,500 per month. Connects to your CRM and financials. Suits finance-led teams that want to keep the model in Excel or Google Sheets.

The Punchline

That founder I mentioned? He used the PULSE calculator. He hired 9 AEs instead of 3. Eighteen months later, they hit $10M.

The math works. But only if you do it.
