BFMT: Best Free Subscriber Acquisition Cost Calculator

Ever wonder how much it really costs you to get one new subscriber? If you own a SaaS business, a subscription box, or even an online course — this number matters. It helps you know where your money is going and whether or not your marketing efforts are paying off.

That’s where our free (SAC) Subscriber Acquisition Cost Calculator comes in. We just need a few inputs and it’ll tell you exactly what you’re paying per subscriber. No spreadsheets. No uncertainty. Just quick, simple answers.

What is Subscriber Acquisition Cost (SAC)?

In simple words, SAC tells you how much you are spending to get one new subscriber. It adds up the amount you spend — e.g., your sales, tools, and marketing — and then divides this by the number of new subscribers you got.

So yeah, if you’re paying more to get a subscriber than you’re taking in from them, that’s a red flag.

Why Should You Care About SAC?

Knowing your SAC can seriously change how you run your business. Here’s why:

• You’ll see which marketing campaigns are actually worth the money.
  
• You can stop wasting budget on stuff that doesn’t work.
  
• You’ll know if it’s the right time to scale.
  
• You’ll start focusing on subscribers who bring real value.
  

When you understand SAC, you get the power to cut down costs without hurting your growth. That’s a win-win.

Here’s How SAC is Calculated

No need to overthink it. The formula is super easy:

SAC = (Marketing Costs + Sales Costs + Tech Costs) / New Subscribers

Let’s say you spent:

• $10K on marketing
  
• $5K on your sales team
  
• $2K on software/tools
  
• And got 1K new subscribers
  

Your SAC would be:

($10,000 + $5,000 + $2,000) / 1,000 = $17 per subscriber

That’s it! That’s the real cost of gaining one new subscriber.

Don’t Look at SAC Alone

SAC gives you great insight, but it’s even better when combined with other metrics. Here’s how:

• Customer Lifetime Value (CLV): If you’re spending $17 to get someone who brings in $300, you’re golden.
  
• Churn Rate: If subscribers are leaving fast, you may need to rethink your SAC.
  
• ROI: Look at how much you earn vs. how much you spend. Combine this with SAC for the full picture.
  

All these numbers help you see what’s working and where to improve.
