TOOL · COPILOT ROI · 4 MIN
Quantify your GitHub Copilot rollout.
Adjust five inputs to model year-one net economic impact, ROI, and payback period. Designed to be conservative — refine with telemetry from an instrumented 30-day pilot before committing budget.
THE MODEL
Five inputs. One number.
INPUTS
ACCEPTANCE RATE32%
Share of suggestions accepted.TIME SAVED12%
Per-engineer productive time recovered.DEFECT-DENSITY DELTA8%
Reduction in production defects.ASSUMPTIONS
- · 1,600 productive engineering hours per FTE per year
- · Defect-density delta translates to 15% of hourly cost in avoided rework
- · Adoption efficiency = 0.5 + acceptance_rate × 0.5
- · License = $19/seat/mo, enablement = $200/seat one-time, amortized year one
