Your blended CAC is $58. To know if this is sustainable, calculate your LTV:CAC ratio. You need an LTV of at least $174 for a healthy 3:1 ratio. Use our LTV Calculator if you need to calculate that first.

Why Per-Channel CAC Matters

Blended CAC hides your best and worst performing channels. If Facebook acquires customers at $40 and Google at $90, your blended $58 looks acceptable but masks an opportunity: shift budget from Google to Facebook. The catch is that channel efficiency changes as you scale, so continuous monitoring matters more than one-time calculation.

CAC and Your Growth Strategy

Your CAC determines how fast you can grow. If your LTV is $340 and CAC is $85, you have a healthy 4:1 ratio and room to increase acquisition spend. But if CAC creeps up as you scale (common with paid channels), your ratio deteriorates. Track CAC monthly and by cohort to spot trends early.

Frequently Asked Questions

What is CAC?

Customer Acquisition Cost (CAC) is the total cost of acquiring a new customer. It's calculated by dividing your total marketing and sales spend by the number of new customers gained in that period.

What is a good CAC?

A good CAC depends on your Customer Lifetime Value (LTV). The general rule is your LTV:CAC ratio should be at least 3:1. For e-commerce, CAC typically ranges from $30-$80 depending on the vertical.

How do I reduce my CAC?

Reduce CAC by improving targeting (reach people more likely to convert), optimizing landing pages (convert more visitors), improving retention (reduce pressure on acquisition), and focusing budget on your most efficient channels.

Should I include organic channels in CAC?

Yes. Include all marketing costs: ad spend, content creation, SEO tools, email platform fees, agency fees, and team salaries. This gives you a true blended CAC.

Does Arktis calculate CAC automatically?

Yes. Connect your ad platforms (Facebook, Google, TikTok) and Arktis calculates CAC per platform, per campaign, and blended - using real conversion data, not platform estimates.
