I run a SaaS company based on a free open source CMS that we developed internally: LocomotiveCMS. For a while, everything was free and open source. 18 months ago we decided to turn it into a profitable company so we launched our first offer: LocomotiveHosting that provides hosting for your LocomotiveCMS websites, as well as free upgrades, daily backup and priority support for $19/month/website. I understand the importance of being able to understand my key metrics such as CAC but I just don't know how to calculate CAC accurately. We don't spend money on Adwords or on SEO which are often the examples that you'll see in blog articles talking about CAC for SaaS. And yet, it would be ridiculous to say that our CAC is $0. We do however have a full time employee working on content marketing. So among the following tasks (which are the ones that take most of our time), what should go into our CAC ? - development of the open source product, LocomotiveCMS - development of LocomotiveHosting, our paid offer - support to LocomotiveCMS users - support to LocomotiveHosting users - writing documentation and tutorials for LocomotiveCMS users. - writing guides, blog posts, sending newsletters to both LocomotiveCMS users and LocomotiveHosting customers - copywriting for our website - improving on-boarding: videos, demo websites, setting up autoresponders with vero or customer.io.... Obvioulsy, if many of the tasks mentioned above go into CAC, our CAC will soar to hundreds of dollars. Thanks a lot for your help
At WP Engine, everything in marketing and sales is included in CAC. Salaries, commissions, coupons, direct advert spend (which you're saying you don't yet have), fees, travel and other costs associated with conferences, etc..
My advice is to err on the side of putting too much in CAC, because that helps you honestly understand the costs. Ignoring some costs just because they don't scale with company size or marginal new customers doesn't make sense to me, it simply means that certain components of your CAC you expect to get more efficient over time. Indeed, they had better! So measure it, instead of ignoring it.
You also might find that some of those direct-spend channels are not as inefficient as they seem compared to things like SEO efforts. Or the reverse! All good things to explore of course.
I'll also note that at $19/mo in the crowded space of CMS offerings you will find that very few channels will be efficient compared to the revenue you're generating. It sounds like you know that, and are dealing with it with "scalable" efforts like content marketing, however again you should be ruthless in understanding how those costs are really translating into orders and whether that's a financially sensible total strategy.
Here's the breakout I would use:
Acquisition: Any work or activity focused on acquiring visitors to the site should be equated as an expense towards CAC. This includes work done by your marketing person + product development focused on your funnel and conversion points.
$40,000/year broken into small timeframes that even if performing at a loss in early months scale to profitability over time. This ties performance goals directly to the role of the employee.
Activation: Once on site, work done to activate these visitors is core product development.
Revenue: If you have a sales guy emailing leads and following up to explain benefits + convert to PU's this should contribute to CAC. The idea here is to use a direct email drip from a person and automate aspects of your drip as your acquisition funnel grows and becomes too cumbersome to manage all the individual parts.
Retention: Email triggers on auto renews, direct reach-out and support on existing customers is a direct overhead expense (cost of doing business) not CAC.
Referrals: Implementing some sort of viral hook for existing customers to refer their colleagues/friends/family is in my mind core product development and should be a value add to your acquisition strategy that grows over time.
The two answers above are great. I would just add that in order for CAC to be useful you also need a reasonably accurate Lifetime Value (LTV) number. It's very important to know if your costs are being amortized over 3 months of revenue or 18 months. I realize you are early in the process of growing this product but its important to make your best guess here, put a stake in the ground with a number and then optimize over time.
Having a LTV number also helps you to decide when to focus on your acquisition costs vs retention costs. Often its not realistic to work on optimizing both at the same time. Good luck!
The CAC can be calculated by simply dividing all the costs spent on acquiring more customers (marketing expenses) by the number of customers acquired in the period the money was spent. For example, if a company spent $100 on marketing in a year and acquired 100 customers in the same year, their CAC is $1.00.
I will be happy to help if you need more information. Feel free to setup a call.
