Recurring Revenue Stocks: The Gift That Keeps Giving

There is a man in my old neighborhood who ran a dead horse rendering business. No competition. Steady demand. Customers came back whether the economy was good or bad, because dead horses do not wait for favorable interest rates. It was not glamorous, but it was reliable – and reliability made him very wealthy while flashier operators went bust every few years.

That dead horse business taught a principle that every serious investor should tattoo somewhere visible: the most powerful business model is one where customers pay you again and again, automatically, without you having to re-sell them every month. In 2025, we do not render dead horses. We sell software subscriptions. But the underlying economics are exactly the same.

Why Does Recurring Revenue Deserve a Premium Valuation?

Imagine two businesses. Both generate $100 million in annual revenue. Business A sells heavy machinery – large one-time purchases. Every January, the sales team wakes up with essentially zero revenue booked and must go hunt for every dollar. Business B sells cloud-based enterprise software on annual contracts. When January arrives, 90% of last year’s customers automatically renew, so Business B wakes up with $90 million already in the bag before anyone makes a single phone call.

Which business would you rather own? Which one lets you sleep at night?

The answer is obvious, and the market agrees. Recurring revenue businesses consistently trade at higher multiples than one-time revenue businesses, sometimes dramatically higher. A traditional software company selling perpetual licenses might trade at 3-5x revenue. A SaaS company with strong subscription metrics can trade at 10-15x or more. The premium exists because predictability has real economic value.

Here is why it compounds:

• Planning becomes possible. When you know with reasonable certainty how much money is coming in next quarter, you can invest in growth, hire talent, and build infrastructure with confidence. Companies that live deal-to-deal cannot do this. They are always one bad quarter away from cutting costs.
• Customer acquisition cost amortizes over time. If you spend $1,000 to acquire a customer who pays you $200 per month and stays for three years, that acquisition cost looks very different than if the customer buys once and disappears. The longer customers stay, the more profitable each one becomes.
• Revenue compounds naturally. Good subscription businesses do not just retain customers – they expand them. A company starts with 10 seats of Microsoft 365, then grows to 50, then adds premium security features, then enterprise analytics. Same customer, growing revenue. This is called net dollar retention, and the best companies run it above 120%, meaning they grow revenue from existing customers alone without signing a single new deal.
• Downturns hit less hard. When the economy contracts, companies cut discretionary spending first. That new marketing campaign? Postponed. That consulting engagement? Canceled. But the CRM software that runs their entire sales operation? The cloud infrastructure hosting their applications? Those renewals happen because switching costs are enormous and the product is embedded in daily operations.

This is the pragmatic beauty of recurring revenue. It does what works, and it keeps doing it. The fundamental algorithm of wealth is repeat what works, and subscription models literally automate that repetition.

How Do You Measure Recurring Revenue Quality?

Not all recurring revenue is created equal. A gym membership is technically recurring revenue, but people cancel gym memberships the way they cancel New Year’s resolutions – quickly and without guilt. Enterprise software contracts are different. Understanding the difference requires knowing a handful of metrics that separate genuinely durable revenue from the merely hopeful kind.

Annual Recurring Revenue (ARR)

ARR is the foundation. It represents the annualized value of all active subscription contracts. If a company has 1,000 customers each paying $1,000 per month, ARR is $12 million. Simple. What matters is the growth rate and the composition. Is ARR growing because the company is adding new customers, or because existing customers are expanding? The best answer is both, but expansion from existing customers is more valuable because it costs almost nothing.

Churn Rate

Churn is the silent killer of subscription businesses. Monthly churn of 3% sounds small until you calculate that over a year, you lose roughly 30% of your customer base. That means you need to replace nearly a third of your revenue just to stay flat, before any growth happens. The best SaaS companies run gross revenue churn below 5% annually. Companies like Adobe or Salesforce often report churn so low it is almost a rounding error, because their products are deeply embedded in customer workflows.

When evaluating churn, look at it on a dollar basis, not just a logo basis. Losing 100 small customers who each pay $50 per month is very different from losing one enterprise customer paying $500,000 per year. Dollar-weighted churn tells the real story.

Lifetime Value to Customer Acquisition Cost (LTV/CAC)

This ratio tells you whether the business model actually works. LTV is how much total revenue a customer generates over their lifetime. CAC is how much it costs to acquire them. A healthy SaaS business runs LTV/CAC above 3x – meaning every dollar spent on customer acquisition returns at least three dollars over the relationship.

Below 3x, the company is spending too much to acquire customers who do not stay long enough. Above 5x, the company likely has strong product-market fit and significant pricing power. Spotify, for instance, has relatively low CAC because people discover the product organically, and once they build playlists and listening history, switching costs become real – not contractual switching costs, but behavioral ones. Nobody wants to rebuild a decade of curated playlists.

Net Dollar Retention (NDR)

This is perhaps the single most important metric for evaluating recurring revenue quality. NDR measures whether your existing customer base is generating more or less revenue than the prior year, accounting for churn, downgrades, and expansion.

NDR above 100% means the company grows even if it never signs another new customer. The elite SaaS companies – Snowflake, Datadog, CrowdStrike – have historically reported NDR in the 120-140% range. This means their existing customers spend 20-40% more each year. Think about what that means for compounding. Even without any new customer acquisition, revenue grows 20-40% annually from the installed base alone. Add new customers on top, and growth rates become extraordinary.

NDR below 100% is a warning sign. It means customers are leaving or spending less faster than remaining customers are expanding. The company is on a treadmill, running harder just to maintain its position.

What Makes a Recurring Revenue Stock Worth Buying at Today’s Prices?

Knowing that recurring revenue is valuable is not the same as knowing when to buy it. The market is not stupid. It prices in the predictability premium, which means subscription businesses often look expensive on traditional valuation metrics. The question is whether they are expensive or just appropriately priced for their economics.

Here is the framework I use:

Start with the Rule of 40. Add the company’s revenue growth rate to its free cash flow margin. If the sum exceeds 40, the business is in healthy territory. A company growing at 30% with 15% FCF margins scores 45 – good. A company growing at 10% with 5% margins scores 15 – concerning. The Rule of 40 forces you to evaluate growth and profitability together, because hypergrowth without any path to profitability is just burning cash with better marketing.

Examine the gross margin. Software businesses should run gross margins above 70%, ideally above 80%. Adobe runs north of 88%. Microsoft’s intelligent cloud segment runs above 70%. High gross margins mean that each incremental dollar of revenue drops significantly to the bottom line as the company scales. Low gross margins in a subscription business suggest the company is really a services business disguised as a software company.

Check management’s capital allocation. A subscription business with strong cash generation should be intelligently deploying that capital – into R&D that deepens the product moat, into acquisitions that expand the platform, or into buybacks when the stock is undervalued. What you do not want to see is management spending lavishly on sales and marketing with deteriorating unit economics, or overpaying for acquisitions to artificially inflate the growth rate. The integrity of management matters enormously. When leadership chases growth metrics at the expense of sustainable economics, the subscription model that should protect you instead becomes a vehicle for value destruction.

Beware the “everyone is doing it” trap. When an entire category gets hot – as SaaS did in 2020-2021 – valuations detach from reality. Companies with mediocre metrics trade at 30-40x revenue because investors extrapolate pandemic-era growth rates forever. That is how you end up buying Zoom at $500 or Peloton at $170. The subscription model was real; the valuations were fiction. Situational ethics apply to investing too. Just because every portfolio manager owns a stock does not mean the price makes sense.

The best time to buy recurring revenue stocks is when the market temporarily misprices them – during broad selloffs, sector rotations, or when a single bad quarter causes panic selling in a company whose long-term economics remain excellent. A SaaS company that misses its growth target by 2% and drops 25% in a day is often a gift, because the subscription base is still there, the customers are still paying, and next quarter’s revenue is already largely booked.

Key Takeaways

• Recurring revenue is the most valuable type of revenue. Predictability reduces risk, enables planning, and justifies premium valuations. A business where customers automatically pay you every month is fundamentally superior to one that must re-earn every dollar.
• Not all subscriptions are equal. Evaluate the quality of recurring revenue through ARR growth, churn rate, LTV/CAC ratio, and net dollar retention. NDR above 120% signals an exceptional business. Churn above 10% annually signals a leaky bucket.
• The Rule of 40 keeps you honest. Growth without profitability is a story, not a business. Demand that subscription companies deliver both revenue growth and a credible path to strong free cash flow margins.
• Gross margins reveal the true nature of the business. Above 80% means genuine software economics with powerful operating leverage. Below 60% means something else is going on, and the “recurring revenue” label may be misleading.
• Buy quality during temporary dislocations. The market regularly overreacts to short-term misses in companies with deeply embedded, high-retention subscription models. These moments are your entry points.
• Management integrity matters. Even the best business model can be destroyed by leadership that prioritizes growth metrics over sustainable economics. Watch capital allocation decisions carefully.

The subscription economy is not a trend. It is a structural shift in how businesses generate and retain revenue. Companies that master the model – deep product integration, low churn, expanding customer relationships – create compounding machines that get more valuable every year without dramatic reinvention. Find them, verify the metrics are real, buy them at reasonable prices, and do what works. Then keep doing it.
