What Does Your Tech Stack Actually Cost?

Tech stack cost per engineer varies significantly by company stage. Startups typically spend $150 to $400 per engineer per month on tools and infrastructure. Series A and B companies range from $400 to $2,500 per month. Growth-stage companies spend $2,000 to $4,000, while enterprises can reach $3,000 to $8,000 per engineer monthly. These figures include cloud infrastructure, developer tooling, SaaS licenses, data platform costs, and security tooling, but exclude salaries and benefits.

In Zylo's 2026 SaaS Management Index, the median company spends about $9,455 per employee per year on SaaS, roughly double the prior year ($4,830 in the 2025 index) as AI-native application adoption surged. Overall AI-native SaaS spend rose 108% year over year, and ChatGPT is now the most-expensed application. Spend still varies widely by industry and company size, and the same report finds organizations leave about 36% of their SaaS licenses unused. These figures cover SaaS subscriptions only and exclude cloud infrastructure, developer tooling, and salaries.

The average company runs approximately 305 SaaS applications (Zylo 2026), up from roughly 275 a year earlier. Most of this spend is decentralized: business units control about 81% of SaaS spend while IT directly manages only around 15%, so a large share of subscriptions are purchased outside central procurement (shadow IT). Large enterprises add roughly 21 new applications every month, which is why portfolios keep growing even as teams try to consolidate. Companies with over 1,000 employees commonly manage 400 or more distinct tools.

Zylo's 2026 SaaS Management Index finds organizations leave about 36% of their SaaS licenses unused. The waste comes from three primary sources: unused licenses (employees who have seats but rarely or never log in), duplicate tools (multiple teams paying for competing products that serve the same function), and auto-renewed contracts for tools that are no longer actively used. A structured SaaS audit can typically reclaim 25% to 40% of this wasted spend.

The average across all industries is approximately 3.28% of revenue spent on IT. However, this varies dramatically by sector. Financial services companies spend 7% to 8% of revenue on technology. Technology companies invest 5% to 8%. Healthcare averages 4% to 6%. Manufacturing and retail companies typically spend 1.5% to 3%. These percentages have been increasing year-over-year as every industry becomes more technology-dependent.

At seed stage (1 to 5 engineers), a lean stack typically runs $800 to $2,000 per month, roughly $150 to $400 per engineer, by leaning on free tiers (GitHub, Linear, Sentry) and keeping hosting under $500 per month. Series A companies (5 to 20 engineers) usually spend $3,000 to $12,000 per month as they start paying for tools that save engineering time. The biggest affordability wins for small teams are avoiding enterprise-tier pricing before you need it, not signing annual contracts too early, and resisting tool sprawl while the team is still small.

Fragmentation shows up as duplicate tools, unused seats, and shadow IT. The average company now runs about 305 SaaS applications and leaves roughly 36% of its licenses unused (Zylo 2026), and business units control around 81% of SaaS spend, so much of it is purchased outside central procurement. The direct financial cost is the 25% to 40% of SaaS spend a structured audit can typically reclaim once duplicate and disconnected tools are consolidated. The hidden cost is the engineering time lost switching between and integrating tools that do not talk to each other.

The most effective cost reduction strategies start with visibility. Conduct a full stack audit to identify unused licenses, duplicate tools, and underutilized services. Right-size cloud resources, which typically saves 20% to 35% immediately. Negotiate vendor contracts during renewal windows with competitive quotes in hand. Consolidate overlapping tools where possible. Commit to reserved instances for predictable workloads to save 30% to 60%. Finally, implement ongoing governance with monthly cost reviews and approval workflows for new tool purchases.
