Hey {{first_name}} 👋, hope you had a great week! In the last issue, we discussed why tracking CAC matters, and now we are moving with the next topic from Financial Metrics content.

Let’s talk about ⬇️

Most SaaS founders obsess over acquiring new customers.

New logos. New ARR. New pipeline. It's where the energy goes, where the board meeting starts, and where the growth narrative lives.

But here's the uncomfortable truth: a leaky bucket with great inflow is still a leaky bucket.

The metric that actually tells you whether your business is building something durable — not just growing — is customer lifetime value. And most founders either don't track it, calculate it wrong, or look at it so infrequently it's practically useless by the time they do.

Today I want to change that.

Let's dig in:

1️⃣ How to Calculate LTV Correctly

2️⃣ Why LTV Is One of the Most Important Metrics in Your Business

3️⃣ The LTV/CAC Ratio — and What It's Actually Telling You

4️⃣ Three Levers That Actually Improve LTV

5️⃣ The Real Challenge With LTV

The goal here is to get a number that actually reflects the economic value of your average customer relationship.

The standard SaaS LTV formula is:

Three inputs. Each one matters:

Here's a quick example to make it concrete. Say your ARPU is $120/month, your gross margin is 80%, and your annual churn rate is 5%:

LTV = ($120 × 80%) ÷ 5% = $1,920

That $1,920 represents the average net profit you can expect from each customer over the life of the relationship.

Notice what's not in that formula: revenue alone. Gross margin is in there for a reason. A customer generating $200/month on a 40% margin business is worth significantly less than one generating $150/month on an 80% margin model. LTV without margin is just revenue — and revenue isn't profit.

The goal here is to understand what LTV is actually telling you — and who else in your organization needs to see it.

LTV isn't just a finance metric. When used properly, it's a strategic input that touches almost every function in the business.

The most important context for LTV, though, is alongside CAC. Which brings us to the most important ratio in SaaS unit economics.

The goal here is to understand whether your growth engine is creating value or destroying it.

LTV/CAC is the ROI calculation for customer acquisition. It answers a deceptively simple question: for every dollar you spend to bring in a new customer, how many dollars of lifetime value do you get back?

The benchmark most investors use:

A ratio of 3:1 or higher is the widely-cited benchmark for sustainable SaaS growth. But like all benchmarks, context matters. A company selling high-ACV enterprise deals with 18-month sales cycles operates differently than a PLG motion with 30-day payback. Know your model before you compare your ratio.

The goal here is to give you practical, high-leverage actions — not abstract advice.

There are dozens of ways to theoretically improve LTV. But most of them trace back to three core levers:

Invest in customer success. Retention is the single most powerful driver of LTV. Acquiring a new customer is almost always more expensive than keeping an existing one — often by a factor of 5x or more. Better onboarding, faster support response times, proactive communication around new features — these aren't soft investments. They're LTV optimization.

Raise your prices. The simplest mathematical lever: higher ARPU directly increases LTV, assuming churn holds. If your product is delivering real value and you haven't revisited pricing in 12+ months, there's a good chance you're leaving LTV on the table. The key is to raise prices in proportion to the value you're delivering — not just because you need more revenue.

Build escalation into your contracts. Usage-based pricing, add-on features, and annual escalation clauses naturally increase net revenue retention over time. When customers grow, their contract value grows with them. That expansion revenue flows directly into LTV — often without the acquisition cost attached to a new logo.

Here's what makes LTV genuinely hard to track: the data you need is scattered everywhere.

Contract start dates and terms live in your CRM. Upsells and downgrades are in your billing system. Renewal rates are in a spreadsheet someone built two years ago. Cost of revenue is in your ERP.

Pulling all of that together, normalizing it, segmenting it by cohort and product line, and doing it consistently every month — that's the actual work. And for most SaaS teams, it means hours of manual effort for a number that's already a few weeks stale by the time it's ready.

The companies that solve this problem — by connecting their FP&A infrastructure directly to CRM and billing data — get something valuable: LTV as a living, real-time metric rather than a quarterly exercise.

And when LTV is current, accurate, and segmented by the right dimensions, it stops being a backward-looking report and starts being a forward-looking growth tool.

That's when it actually changes decisions.

Hit reply and tell me: are you currently tracking LTV, and if so, what's your biggest challenge with it — the data, the formula, or getting other teams to actually use it? I read every response.
