Developer Tooling ROI 2027 Calculator
Estimate the return on a developer tool such as an AI coding assistant. Enter the number of developers, the tool's price per developer per month, the average fully-loaded cost of a developer, and the productivity gain you expect. Nothing is built in: the price, salary and gain in the boxes are placeholders, and the productivity gain in particular is your own assumption — the result is only as good as that estimate.
How the ROI Is Calculated
Annual tool cost = developers × price per month × 12. Value of time freed = developers × productivity gain × fully-loaded cost per developer. ROI = (value − cost) ÷ cost. Example: 50 developers at $39 a month cost $23,400 a year; a 25% gain on a $220,000 fully-loaded cost is worth $2,750,000, for a net gain of $2,726,600.
The Productivity Gain Is the Whole Question
Because tool prices are small next to salaries, almost any gain produces a large ROI on paper. The break-even line shows how small the gain needs to be to cover the licence. The harder question is whether time saved on coding turns into more shipped work, so measure outcomes such as cycle time or delivered features rather than relying on a headline percentage.
What Is Not Included
Rollout and training time, security review, usage that falls short of full adoption, and any change in code quality or review load are not included. If only part of the team uses the tool, enter that number of developers.
