RevOps Diagnostic &
Capacity Calculator

The computational core of the 12-question RevOps audit — team ratios, funnel math, headcount gaps, CAC, and Magic Number. Plug in your numbers, see where you stand against benchmark. No signup, nothing stored.

Built from the RevOps Diagnostic Guide & Account Capacity benchmarks — colinspecter.com

What this calculator does: a RevOps capacity planning calculator turns the questions a sales leader needs to answer before a board meeting — how many reps to hire, whether your team ratios are healthy, what your funnel actually produces, and how efficiently sales and marketing dollars convert into revenue — into a live tool. Enter your team, funnel, and spend numbers below and it returns benchmarked ratios, a headcount gap, and unit economics including CAC and Magic Number.

It's free, it's not gated, and nothing you enter is stored or sent anywhere. If you'd rather talk through your specific numbers before you present them, book time with Colin directly.

Team ratios & capacity

Steps 8–10 of the diagnostic: what's the right mix of sellers to SEs, SDRs to sellers, and ABM to AEs? Enter your current team and see how your ratios sit against typical ranges.

Funnel math

Step 12 of the diagnostic: how many discovery meetings do you need, what converts to pilot, what closes — and what happens if you move conversion by a couple points?

From CRO Fundamentals: for every sales & marketing dollar spent, how much new ARR does it generate — and how fast do you recoup what it costs to acquire a customer?

Why these numbers matter before your board meeting

Boards ask the same handful of questions every quarter: is the team sized right, is spend converting into revenue efficiently, and what does it take to hit next year's number. This calculator answers those with your own inputs instead of gut-feel:

Frequently asked questions

What is a RevOps capacity planning calculator?

A RevOps capacity planning calculator turns the questions a sales leader needs to answer before a board meeting — how many reps to hire, whether team ratios are healthy, what the funnel produces, and how efficiently sales and marketing dollars convert into revenue — into a live tool. You enter your team, funnel, and spend numbers, and it returns benchmarked ratios, a headcount gap, and unit economics like CAC and Magic Number.

How do I calculate CAC payback period?

CAC payback period is the number of months it takes to recoup what you spent to acquire a customer, using gross-margin-adjusted revenue rather than raw revenue, since margin is what actually pays the cost back. Divide your Customer Acquisition Cost by (average annual revenue per customer times gross margin, divided by 12). A payback period of 24 months or less is a healthy benchmark for most SaaS businesses.

What is a good SaaS Magic Number?

The Magic Number measures how much new ARR you generate for every dollar of sales and marketing spend. A Magic Number of $0.80 or higher per dollar invested is the minimum healthy benchmark; above $1.00 is considered excellent efficiency.

What is a healthy AE to SDR ratio?

Early-stage sales orgs typically run close to a 1:1 AE to SDR ratio, since pipeline generation needs more hands-on support. As the motion matures and inbound or expansion pipeline grows, that ratio typically shifts toward 1 SDR supporting up to 3 AEs.

How many AEs can one ABM rep support?

One account-based marketing rep can typically support 12 to 15 AEs with coordinated, account-specific campaigns. Fewer AEs per ABM rep allows for deeper account customization; more than 15 usually stretches the ABM function too thin to run truly targeted programs.

Is this RevOps calculator free to use?

Yes. The calculator is free, requires no signup, and nothing you enter is stored. If you'd rather walk through your numbers live before presenting them to a board, you can book time directly with Colin Specter at calendly.com/colin.
