This calculator estimates ROI by assuming a red team engagement has a meaningful chance of finding at least one critical, previously-unknown gap (a detection blind spot, a privilege escalation path, an unmonitored admin account) whose remediation prevents an incident of a given estimated cost, weighted by the probability that gap would otherwise have been exploited before your next assessment cycle. It's a probabilistic estimate meant to frame budget conversations, not a guarantee, since the actual value of any single engagement depends heavily on scope, adversary emulation quality, and whether findings are actually remediated afterward.", "formula": "Expected value = P(critical finding found) × P(would've been exploited before next assessment) × avg cost of resulting incident − engagement cost.", "dateModified": "2026-09-30", "run_url": "https://www.revenuelab.fyi/api/public/calc?tool=red-team-exercise-roi", "inputs": [ { "id": "engagementCost", "label": "Red team engagement cost", "kind": "number", "hint": null, "default": 65000, "unit": null, "min": 0, "max": null }, { "id": "probCriticalFinding", "label": "Probability of finding ≥1 exploitable critical gap (%)", "kind": "number", "hint": null, "default": 70, "unit": null, "min": 0, "max": 100 }, { "id": "probWouldBeExploited", "label": "Probability that gap gets exploited before next assessment (%)", "kind": "number", "hint": null, "default": 20, "unit": null, "min": 0, "max": 100 }, { "id": "avgIncidentCost", "label": "Avg cost of resulting incident if exploited", "kind": "number", "hint": null, "default": 500000, "unit": null, "min": 0, "max": null }, { "id": "remediationCost", "label": "Estimated remediation cost for findings", "kind": "number", "hint": null, "default": 15000, "unit": null, "min": 0, "max": null } ], "outputs": [ { "id": "netExpectedValue", "label": "Net expected value of engagement", "format": "currency", "hint": null, "primary": true }, { "id": "expectedAvoidedLoss", "label": "Expected loss avoided", "format": "currency", "hint": null, "primary": false }, { "id": "totalProgramCost", "label": "Total program cost (engagement + remediation)", "format": "currency", "hint": null, "primary": false }, { "id": "roiPct", "label": "Expected ROI", "format": "percent", "hint": null, "primary": false }, { "id": "engagementCost", "label": "Red team engagement cost", "format": "currency", "hint": null, "primary": false } ], "worked_example": { "inputs": [ "Red team engagement cost: 65000", "Probability of finding ≥1 exploitable critical gap (%): 70", "Probability that gap gets exploited before next assessment (%): 20", "Avg cost of resulting incident if exploited: 500000", "Estimated remediation cost for findings: 15000" ], "outputs": [ "Net expected value of engagement: -$10,000", "Expected loss avoided: $70,000", "Total program cost (engagement + remediation): $80,000", "Expected ROI: -13%", "Red team engagement cost: $65,000" ] }, "how_to": { "title": "How to use this", "steps": [ "Enter red team engagement cost.", "Enter probability of finding ≥1 exploitable critical gap (%).", "Enter probability that gap gets exploited before next assessment (%).", "Enter avg cost of resulting incident if exploited.", "Enter estimated remediation cost for findings.", "Read your net expected value of engagement on the right — it updates as you type.", "Hit Share to keep the scenario or send it to someone." ] }, "scenarios": [ { "name": "Conservative", "description": "Lower-end numbers — what if things land soft?", "values": { "engagementCost": 39000, "probCriticalFinding": 40, "probWouldBeExploited": 10, "avgIncidentCost": 300000, "remediationCost": 9000 } }, { "name": "Typical", "description": "Defaults — the most common real-world setup.", "values": { "engagementCost": 65000, "probCriticalFinding": 70, "probWouldBeExploited": 20, "avgIncidentCost": 500000, "remediationCost": 15000 } }, { "name": "Ambitious", "description": "Higher-end numbers — what if things really pop?", "values": { "engagementCost": 104000, "probCriticalFinding": 100, "probWouldBeExploited": 30, "avgIncidentCost": 800000, "remediationCost": 24000 } } ], "limitations": [ "Results are estimates before tax, fees, and inflation unless an input explicitly covers them.", "Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.", "This is educational maths, not financial advice.
