Is Your Tech Company Profitable? Understanding CAC and LTV

As a founder or marketer, you’re building the engine of your tech company. But are you building it with a clear plan? Many marketing teams focus on leads and conversions without fully understanding their core economic drivers—Customer Acquisition Cost (CAC) and Lifetime Value (LTV).

These two metrics are more than just numbers; they’re the foundation for sustainable growth, scalability, and profitability. This guide will explain how to calculate and interpret your CAC and LTV, giving you a clear picture of your business's financial health.

You’ll learn:

• The difference between Marketing CAC and Fully Loaded CAC.
• How to set realistic LTV targets based on your marketing spend.
• The impact of sales labor on profitability.
• What strong CAC:LTV ratios look like and why they matter.

Step 1: Break Down Marketing CAC

Customer Acquisition Cost (CAC) is the total amount you spend to gain one new customer. Marketing CAC, a common starting point, only includes marketing expenses like ads, content, and events.

For example, let’s say your Marketing CAC is $12,500. That’s how much it costs to acquire one customer through marketing activities alone.

Now, to assess if this is a good investment, compare it to the value a customer brings over their lifetime—the LTV:CAC ratio. For Marketing CAC, target ratios are higher because sales labor isn’t included yet:

• Healthy Ratio: 5:1 LTV to Marketing CAC
• Strong Ratio: 8:1 LTV to Marketing CAC

Using these benchmarks:

• Minimum LTV Target: $12,500 × 5 = $62,500
• Strong LTV Target: $12,500 × 8 = $100,000

If your Marketing CAC is $12,500, your LTV should be at least $62,500 for a sustainable business, and $100,000 for strong, scalable growth. Falling short may indicate a problem with your marketing efficiency or customer retention.

Step 2: Understand Fully Loaded CAC

Marketing CAC is helpful, but it doesn’t tell the full story. Fully Loaded CAC includes marketing costs plus the sales labor required to close a deal. This provides a more complete picture of your acquisition cost.

Fully Loaded CAC = Marketing CAC + Sales Labor per Customer

The ideal LTV:CAC ratios for Fully Loaded CAC are:

• Minimum Healthy: 3:1
• Ideal: 3.75:1
• Strong/Elite: 5:1

Let’s see how sales labor changes the equation using $12,500 as your Marketing CAC.

Scenario 1: Low Sales Labor

• Sales Labor per Customer: $3,000
• Fully Loaded CAC: $12,500 + $3,000 = $15,500
• Minimum LTV Target (3:1): $46,500
• Strong LTV Target (5:1): $77,500

Scenario 2: Moderate Sales Labor

• Sales Labor per Customer: $5,000
• Fully Loaded CAC: $12,500 + $5,000 = $17,500
• Minimum LTV Target (3:1): $52,500
• Strong LTV Target (5:1): $87,500

Scenario 3: High Sales Labor

• Sales Labor per Customer: $10,000
• Fully Loaded CAC: $12,500 + $10,000 = $22,500
• Minimum LTV Target (3:1): $67,500
• Strong LTV Target (5:1): $112,500

Sales labor has a significant impact on your profitability. Companies with efficient, low-touch sales processes can achieve profitability at lower LTVs compared to those with high-touch enterprise sales teams.

Bringing It Together: The Importance of a Healthy LTV:CAC Ratio

Let’s apply these numbers to a real-world example. Say your average LTV is $90,000.

• With high sales labor ($10,000 per customer), your Fully Loaded CAC is $22,500. This results in a 4:1 LTV:CAC ratio, which is highly profitable.
• With lower sales labor ($5,000 per customer), your Fully Loaded CAC is $17,500. This gives a ~5:1 LTV:CAC ratio, placing you in the top tier of tech companies.

Achieving these ratios provides stability and flexibility. You can confidently scale your marketing spend, expand your sales team, and invest in growth, knowing your business fundamentals are sound.

SaaS Companies: Different Metrics, Different Expectations

For SaaS companies, especially those offering lower-cost subscriptions, the economics differ significantly. A $59/month SaaS product will not achieve the same LTV as a high-ticket enterprise product, and that’s okay. The key for SaaS is managing churn and keeping CAC low.

Realistic SaaS LTV and CAC Targets

At $59/month, churn rates heavily influence LTV:

• 10% churn: ~10 months lifespan → $590 LTV
• 7% churn: ~14 months lifespan → $826 LTV
• 5% churn: ~20 months lifespan → $1,180 LTV

Target CAC for SaaS companies typically falls between 20–35% of LTV, with payback periods of 1–4 months. For an LTV of $600–$1,200, the acceptable CAC range is $120–$400.

How SaaS Companies Can Scale

A well-run acquisition program for low-cost SaaS might generate:

• 5–15 customers/month on a $5,000–$10,000 ad budget
• CAC between $150–$300
• Retargeting contributing 20–40% of conversions

With optimization, companies can grow to:

• 20–30 new customers/month
• CAC dropping to $100–$200
• Improved retention and LTV as churn decreases

The key is to focus on efficiency and churn reduction, rather than chasing unrealistic LTV benchmarks.

Your Next Steps Toward Growth

Whether you're running a SaaS company or a high-ticket enterprise, understanding CAC and LTV is essential for profitable growth. Here’s how to get started:

1. Calculate Marketing CAC: Determine your current cost to acquire a customer through marketing campaigns.
2. Set LTV Targets: Use benchmarks to define the LTV needed for a healthy business.
3. Calculate Fully Loaded CAC: Include both marketing and sales labor costs to get a complete view of acquisition expenses.
4. Evaluate LTV:CAC Ratios: Assess whether these ratios meet industry standards for sustainability and scalability.

By mastering these metrics, you can make smarter decisions, optimize your processes, and build a business positioned for long-term success.
