Custom Software Development Statistics 2026

Most "software development statistics" pages recycle the same numbers year after year, often from surveys that have since been replaced. This page collects the 2026 figures that matter to someone budgeting for custom software, each taken from the original source and linked so you can check it. Where two sources disagree, we show both and explain why.

The key numbers at a glance

Market size: how big is custom software development?

Market research firms do not agree on the size of the custom software market, because each one draws the boundary differently. Some count only bespoke development services; others include enterprise software customization or mobile apps. Treat any single figure as an estimate, not a measurement.

• Global Market Insights estimates the custom software development market at $44.2 billion in 2025, growing from $50.6 billion in 2026 to $213.4 billion by 2035, a compound annual growth rate of 17.3%. It puts North America at $16.6 billion in 2025, with the US alone at $15.5 billion, and cloud deployment at 67% of the market.
• Grand View Research forecasts the market to reach $146.18 billion by 2030, growing at 22.6% a year from 2025 to 2030. It reports that enterprise software held over 60% of revenue and cloud deployment 57% in its base year.

The two forecasts differ by tens of billions of dollars because they measure different things. Both agree on the direction: double-digit annual growth, driven mostly by large enterprises and cloud-hosted systems.

The bigger picture: total software spending

Custom development is a small slice of what businesses spend on software. Gartner's April 2026 forecast puts worldwide spending at:

Gartner attributes much of the software growth to generative AI, with spending on GenAI model development forecast to more than double year over year. Data center spending, driven by AI infrastructure, is the fastest-growing segment by far.

What custom software projects cost

Clutch's pricing data, based on verified client reviews and last updated in September 2026, gives the most widely cited cost benchmarks:

• Average project cost: $132,480
• Average project length: about 13 months
• Average monthly cost: about $10,209
• Most common provider hourly rate: $25–$49

Clutch's typical hourly rates by country:

These are marketplace figures: they count every firm listed on Clutch, from freelancer-led shops to large agencies. That is why they run lower than the rates experienced, project-managed teams usually quote. For a breakdown by project type and seniority, and a worked example you can redo with your own numbers, see our custom software development cost guide.

Developer pay and job outlook

The US Bureau of Labor Statistics publishes the most reliable pay and employment data for the US, and it is the benchmark most agency rates are ultimately built on.

BLS expects about 106,100 openings a year across the combined group over the decade, most of them from people changing occupations or retiring rather than from new roles.

One correction worth knowing: many statistics pages still quote a 17% growth projection for 2023–2033. That projection has been replaced. The current BLS outlook is 10% for 2025–2035.

UK developer pay

For UK readers, IT Jobs Watch tracks advertised pay. In the six months to October 2026:

• Permanent software developers (England): median salary £65,000, with £40,000 at the 10th percentile and £100,000 at the 90th. The London median was £73,663.
• Contract software engineers (UK): median day rate £550, with £363 at the 10th percentile and £750 at the 90th. The London median was £625; outside London, £525.

We cover what those rates mean for a UK project budget in bespoke software development cost in the UK.

AI in software development

The Stack Overflow Developer Survey 2025 is the largest annual survey of working developers. Its AI findings:

• 84% of respondents use or plan to use AI tools in their development process, up from 76% the year before.
• 47.1% use AI tools every day; among professional developers the figure is about 51%.
• Only 32.7% trust the accuracy of AI output (3.1% highly, 29.6% somewhat), while 45.7% distrust it.
• The most common frustration, cited by 66%, is "AI solutions that are almost right, but not quite."
• About 31% use AI agents at work at least occasionally; 37.9% have no plans to.

The gap between use and trust matters for buyers. AI tools make development faster, but the time saved is partly spent reviewing and correcting output. It is also why so many apps built quickly with AI tools need engineering work before they can serve real customers, which we cover in vibe-coded app to production: what breaks.

SaaS spending: the cost custom software is often measured against

Many custom software projects exist to replace or connect subscription tools, so SaaS spending is part of the picture. Zylo's 2026 SaaS Management Index, based on more than 40 million licenses and $75 billion in spend, reports:

• Median SaaS spend per employee: $9,455
• Unused licenses: organizations leave an average of 36% of their SaaS licenses unused, measured against recommended utilization levels
• Who controls the budget: business units control 81% of SaaS spend; IT directly manages 15%
• AI-native apps: spend up 108% year over year overall, and 393% in organizations with more than 10,000 employees
• Budget surprises: 78% of IT leaders surveyed reported unexpected charges tied to consumption-based or AI pricing in the past year, and 61% had to cut projects because of unplanned SaaS cost increases

When it makes sense to replace subscriptions with your own software, and when it doesn't, is the subject of replacing SaaS with custom software.

What these numbers mean if you are budgeting

1. The average project is bigger than most first budgets. Clutch's $132,000 average over 13 months is a better anchor than the low figures some vendors advertise. Plan for roughly $10,000 a month of delivery over a year for a typical build.
2. Rates follow salaries. A US developer's median pay works out to about $64 an hour before benefits, overheads, and project management. Agency rates of two to four times that are normal, not a sign of overcharging.
3. Location is still the largest price lever. The same project can cost two to four times more depending on where the team sits. Our hourly rates by region post breaks this down.
4. AI lowers some costs and raises others. Coding goes faster, but review, testing, and security matter more, not less.
