ROI Calculator

The ROI module quantifies the return on investment of quantum computing for your specific workload. Provide your classical benchmark, problem parameters, and target backend — QCOS calculates speedup, cost comparison, break-even point, and generates a PDF Quantum Proof Pack suitable for board-level reporting.

What the ROI Module Calculates

Metric	Description
Quantum speedup	Theoretical and practical speedup vs. best classical algorithm
Cost comparison	Quantum credits vs. cloud/HPC classical cost for same result
Break-even horizon	When quantum surpasses classical given hardware roadmap
Risk-adjusted ROI	Expected value accounting for NISQ noise and error rates
Proof Pack PDF	Executive report with methodology and assumptions

LaTeX source and raw data variants: POST /api/v1/roi/report/latex, POST /api/v1/roi/report/data. The PDF contains:

Executive summary with key metrics
Methodology and algorithm selection rationale
Classical vs. quantum cost breakdown
Speedup projections to 2030 (with hardware roadmap)
Break-even analysis chart
Risk assessment matrix
Generated by the QCOS ROI Engine with timestamp

Compare Multiple Scenarios

POST /api/v1/roi/calculate/scenarios

Takes the same body as /calculate and returns the conservative, base, and aggressive scenarios side by side, together with the pricebook_version used. To compare providers for a given workload volume:

GET /api/v1/roi/compare-providers?evaluations=100&shots_per_eval=1000
