SSEBITDA – A steady-state profit metric for SaaS companies

This is the fourth article in a series on novel ideas for SaaS metrics, which started with The unprofitable SaaS business model trap, COC: a new metric for cancellations, and The mistake of 1/c in LTV.

Its tough for a growing SaaS business to ascertain whether or not it’s truly profitable.  Here’s a way to do it.


First model: EBITDASM

When Rackspace was scaling quickly, they had an interesting metric they called EBITDASM to answer the question: “Are we truly ‘spending to grow,’ or are we just fundamentally unprofitable?”

Here’s the logic:

We (Rackspace) have extremely efficient mechanisms for acquiring customers. When you add up all our costs in Sales and Marketing (SaaS metric: CAC), the result is very small compared to the total revenue we’ll earn from than customer over the next few years (SaaS metric: LTV).

Of course that means we’ll be intentionally unprofitable for now, because the cost to acquire a customer is spent today, but the revenue takes years to trickle in. That should be OK since we’ll be profitable in the long run. But we also know many companies think this way but are not profitable in the long run.

How will we know whether we really have a profitable business underneath this “spend to grow” behavior?

Well, since we know that all our S&M (Sales and Marketing) costs is indeed money well-spent, let’s exempt that cost from our monthly profit calculation, and see whether we’re profitable! If yes, we’ll make that money back. If not, we’re not yet “truly” profitable.

They call the resulting metric EBITDASM (since it’s Earnings not only Before Interest, Taxes, Depreciation, and Amortization — a common way to measure profit – but also before Sales and Marketing).

I like this model, and we’ve used it to-date at WP Engine.

The problem with EBITDASM

Suppose a company has a high CAC compared with LTV, i.e. unlike Rackspace they’re not financially efficient at acquiring customers versus how much gross revenue those customers represent.  Then an assumption above breaks down: it’s not smart for the company to spend as much as possible to acquire new customers.

What ratio of LTV:CAC is “good enough” that the logic about is sound?  Some say 3. Some say 5 is truly healthy. Some day 1 is fine if it’s improving. The real answer will lie somewhere between lowering CAC, increasing customer retention, decreasing variable costs, increasing average revenue, overhead costs, and other metrics related to the definitions of CAC and LTV.

How to resolve this, objectively?

Faithful readers might at this moment have the flash of realization that I had when considering that litany of metrics — they’re the almost same litany that come together neatly in the definition of COC (Cost of Cancellation).  It turns out that COC is the key to this metric of “underlying profitability.”

Framing the Solution: Steady-State profitability: SSEBITDA

Reframing the question leads us to the simple conclusion.

Let’s think of this metric as steady-state profitability, which I’ll abbreviate SSEBITDA.  Meaning: “If we were neither growing nor shrinking — thus in a ‘steady-state’ — what would our profit margin be?”

Having read the previous article on COC, the formula is simple:


Justification: To find steady-state profit, take actual profit, but exclude Sales and Marketing costs (because in steady-state we’re not trying to grow, so we’re not spending to grow), but then include COC (because by definition that’s the replacement cost of cancellations, which we need to incur to prevent revenue from shrinking).

This neatly and objectively answers the questions around “are we truly ‘spending to grow’ or are we using growth as an excuse to in fact just be unprofitable?” Because if we’re profitable in steady-state — even if actual spend takes us into the red — we know that the fundamental financials are profitable.

Corollary: Profitable Growth Rate

Another interesting metric falls directly out of SSEBITDA — “Profitable Growth Rate,” i.e. the rate of revenue growth the company can self-fund while still being profitable.

Where p is the cost of a dollar of revenue (defined in the COC article):

Profitable Growth Rate = SSEBITDA / p

Justification: If we put 100% of the funds from steady-state profitability into growth, we spend p dollars to earn each dollar of new recurring revenue.

Any growth larger than that will require being unprofitable, by a known amount. This is handy, because now we can justify “spend to grow” with precision.

For example, if SSEBITDA is 12% and p is 4, the company can grow at 3%/mo using its own money.  Supposing the company is willing and able to spend more to grow at 8%/mo, it will be unprofitable by 20% (5% growth over profitability, multiplied by spending 4 dollars to earn ever 1 dollar of revenue).  A company in exactly this situation I think you can say with confidence is indeed “spending to grow” in a responsible manner, and will result a profitable business once the dust settles.

More thoughts on SSEBITDA

A negative SSEBITDA still isn’t necessarily a bad thing.  It depends on the context and goals of the company.

For example, an earlier-stage high-tech SaaS company will be spending much more in R&D as a percentage of revenue than a later-stage company. Or a mid-stage company (like WP Engine) might have higher G&A spend (office space, finance, legal, HR) as a percentage of revenue, until it grows into those services. Those are expenses that eat into EBITDA and thus SSEBITDA, but that doesn’t mean the company won’t be profitable with larger scale.

Here’s a few thoughts around how I interpret the metric:

  1. Understand the pieces.  If you’re negative because GPM is low or COC is high, that’s an unprofitable model, and you need to address the root causes. If you have intentionally high R&D costs because you’re investing in product, and a bump in G&A because you just moved into a new office space, you know those will right themselves over time.  You might even calculate an “expected SSEBITDA after scale” where e.g R&D plus G&A costs total 30% of revenue and see how you’re doing.
  2. Watch it directionally.  At WP Engine we watch it move month over month from negative to positive and then continue to grow. While you see a positive trend, not just in the overall metric but in the pieces underneath, and when you have a roadmap for years to come about how you’re going to continue improving those metrics, that’s healthy regardless of the absolute value of the metric today.
  3. Once positive, growing as a percentage of revenue could be less important.  Consider that if SSEBITDA is steady 10% of revenue, and the company is growing, then in absolute dollars SSEBITDA is growing.  Of course it’s always great to see improvement in this metric as a percentage, but certainly it’s logical for a company to turn some percentage points back into investment in the business for de-risking and further growth rather than maniacally increasing this metric.

What do you think?

Let’s continue thinking out loud in the comments.

    Great article – even though I have been tracking most of these metrics for some time, it took me a while to figure out how to calculate this for us. Maybe you could expand the post with a detailed example?
    Anyway, I will post my rough calculation, wonder if I got it right.
    Our COC I estimate at 4.5% (Net churn is 0.5%, Payback period is 9 months based on average MRR of $60 and CAC of $450)
    We currently run at break-even point so I figure our EBITDA is 0%
    The marketing cost to our revenues is 23% ( I divided our monthly marketing cost to our current MRR) – is that how you calculate SM??
    SSEBITDA = 0% + 23% – 4.5% = 18.5%
    Divided by p, this gives 2% monthly growth based on our own funds – which is actually exactly our monthly growth for the last ~18 month. So it seems to be checking out.
    Would appreciate comments on my calculation!

      Yup that’s right! Although I get p=7.5=450/60 rather than 9.

      Nice to hear the math all worked out to what you’re observing — that’s a good reality-check.

      I would say a good next-challenge for you would be to figure out how to increase MRR (best) or decrease CAC on average. You should be able to either be more profitable or increase your growth rate.

        yeah, my bad, was doing math in my head and confused $540 with $450 :-)
        Thanks Jason!

    I mostly like it, except for those businesses where customers’ LTV values are “lumpy”. I’m thinking of B2B design wins where 1) you have big upfront R&D, and 2) a few customers’ LTV will be 100X that of the crowd, 3) design win to revenue time lag has big-time variance. Yeesh.

    • Jason Cohen

      I agree — but the case you described really isn’t a product-based business, but rather a customer-solution business. One of the primary advantages of SaaS is a single platform with specific (i.e. limited) customization such that the company can scale (i.e. backend, support, R&D).

      If that’s not the case, and a sale requires massive and special R&D, that’s not a repeatable business, that’s high-dollar consulting which happens to have a repeating revenue model behind it for continuing services.

      That’s perfectly fine of course, but not the business model that you can apply this sort of logic to.

      Indeed, I don’t think the concept of “LTV” is meaningful anyway with that kind of model. You should be looking at it as per-project, like a consulting company would.

    i wonder how this translates across listed companies
