Your SaaS Costs Are Growing Faster Than Your Revenue

The Gap That's Eating Your Margins

Here's a number your SaaS vendors don't want you to think about: 11.4%. That's how fast SaaS pricing increased year-over-year in 2025. Not the headline CPI number. Not some cherry-picked outlier. The broad, industry-wide rate of SaaS price inflation.

Now here's your number: 5-8%. That's the revenue growth rate for most mid-market companies. Good, steady growth. Nothing wrong with it.

Except when your costs grow at 11.4% and your revenue grows at 5-8%, the math has a very predictable ending.

Key Takeaways

The 5-Year Projection

Let's make this concrete. Take a mid-market company with $10M in revenue and $500K in annual SaaS spend (conservative — many spend far more). Apply the actual growth rates.

SaaS spend as a percentage of revenue increases from 5.0% to 6.4% over five years. That doesn't sound dramatic until you calculate what it means in dollars.

Cumulative SaaS spend over those 5 years: $3,496,500. If SaaS costs had grown at the same rate as revenue (6%), the cumulative spend would be $2,818,500. The inflation gap costs you $678,000 over five years — and that's with a modest starting budget.

For companies with $1M+ in SaaS spend (common at 200+ employees), the gap exceeds $1.3 million.

Why SaaS Prices Keep Rising

This isn't random. Three structural forces are driving SaaS inflation above revenue growth, and none of them are going away.

1. Private Equity Is Extracting Value

PE firms have discovered SaaS as a cash extraction vehicle. The playbook: acquire a SaaS company, cut R&D and support costs, raise prices. Customers are locked in by switching costs, so they pay. Some PE-backed vendors have implemented increases as high as 900% post-acquisition.

If your vendor has been acquired by PE in the last 3 years, budget for 15-25% annual increases. That's not pessimism. That's the data.

2. AI Surcharges Are the New Normal

Every SaaS vendor is bolting on AI features and charging a premium. ServiceNow's AI add-on costs 30-45% on top of existing license fees. Microsoft's Copilot adds $30/user/month across the entire Office 365 base. Salesforce's Einstein AI costs $75/user/month on top of already-premium pricing.

The question nobody asks: are you using these AI features? For most companies, the answer is no. But you're paying for them anyway because they're bundled into the tier you need for other reasons.

3. Per-Seat Models Scale Against You

Per-seat pricing was designed when teams were small. It becomes punitive at scale. Every new hire increases your SaaS bill across 15-30 tools simultaneously. A single new employee can trigger $5,000-$15,000 in incremental annual SaaS costs — before they've written a line of code or closed a deal.

Your SaaS costs scale linearly with headcount. Your revenue per employee does not.

The Waste Multiplier

Here's where the CFO math gets really ugly. You're not just overpaying at inflating prices. You're overpaying for software people don't use, at inflating prices.

30-53% of SaaS licenses go unused in any given month. The average mid-market company wastes $915,000 per year on unused subscriptions. And that waste inflates right along with everything else.

If 35% of your $500K SaaS budget is waste ($175,000), that waste grows to $195,000 next year, $217,000 the year after, and $299,000 by year five. You're paying an 11.4% annual increase on software nobody opens.

Five-year cost of inflating waste alone: $1,224,000.

What Negotiation Actually Gets You

The standard advice is to negotiate harder at renewal time. Push back on the increase. Threaten to leave. Get a "discount."

Here's what actually happens: your vendor offers a 3-year lock at 8% annual increases instead of 12%. You feel like you won. But 8% compounding annually still means your costs grow 26% over three years while your revenue grows 19%. You didn't close the gap. You slowed the bleeding.

SaaS optimization platforms (Zylo, Vendr, Vertice) are useful for eliminating pure waste — killing unused licenses, consolidating duplicate tools. That's table stakes. Every CFO should do it. But optimization doesn't change the structural problem: per-seat, annually-inflating pricing models are fundamentally misaligned with your business economics.

The Structural Fix

The companies pulling ahead aren't negotiating better deals. They're eliminating the recurring cost entirely.

A custom-built tool has no per-seat fee. No annual increase. No AI surcharge. No vendor deciding to raise prices because their PE owners need to hit a number.

The cost structure of custom vs. SaaS over 5 years:

That's one tool. Most companies have 3-5 tools that score as strong replacement candidates. The compounding savings across your stack are substantial.

How to Present This to Your Board

If you're a CFO building the case for SaaS replacement, here's the framing that works:

The board doesn't need to be convinced that SaaS is bad. They need to see that the alternative is cheaper, lower-risk, and available now.

The Window Is Closing

AI-assisted development has compressed custom build timelines by 30-55%. A custom CRM that used to cost $150K now costs $30K-$60K. Every quarter that SaaS prices increase, the ROI on custom replacement improves.

But here's the thing about compounding costs: every year you wait, the cumulative gap grows. The $678K gap over 5 years becomes a $1.5M gap over 7 years. Delay is expensive.
