Is AI coding actually worth it?
The seat price of an AI coding assistant is tiny next to a developer's salary, so on paper the ROI looks enormous — a few percent of time saved covers the cost many times over. That is exactly why the simple calculation above almost always looks great, and exactly why it can be misleading.
Where the estimate breaks down
Time saved at the keyboard is not the same as faster delivery. AI-generated code can take longer to review, can increase rework when it's subtly wrong, and can raise duplication and tech debt that slows the team later. If coding gets faster but review queues, meetings, and rework absorb the gain, cycle time doesn't move — and the ROI never shows up in what customers actually receive.
How to measure real AI impact
The credible approach is to compare AI-assisted work against the rest of your delivery on both speed and quality — ideally with a difference-in-differences design that controls for everything else changing at the same time. That means detecting AI co-authorship automatically, then tracking cycle time, PR health, change failure rate, and maintainability for adopting versus non-adopting teams. That's the difference between “we think AI helps” and evidence you can put in front of a board.
Frequently asked questions
How do you calculate AI coding ROI?
A simple model compares annual tool spend (developers × seat price × 12) against the value of time saved (developer cost × share of time spent coding × percentage of coding time saved). The result is an estimated net return and ROI multiple.
Is GitHub Copilot worth it?
For most teams the seat cost is small relative to developer salaries, so even a few percent of genuine time savings pays it back. The real question is whether the time saved converts to faster delivery without raising rework or tech debt — which requires measuring AI-assisted work against the rest, not just trusting self-reported savings.
Why is the calculator only an estimate?
It assumes reported time savings translate directly into value. In practice, faster coding can be absorbed by review queues, meetings, or increased rework. Measuring actual delivery and quality outcomes for AI-assisted code is the only way to know your true return.
Measure your real AI impact
DXSignal auto-detects AI-assisted work and measures it against the rest — speed and code quality together — so you know whether your AI investment is actually paying off.
