This phishing control roi calculator helps security, finance, and operations teams compare avoided expected loss with control costs using transparent assumptions they can adjust. Enter the organization’s own incident frequency, probability, impact, timing, or cost data to see a main estimate and supporting measures. The result is designed for scenario planning, budgeting, and control discussions—not as a prediction or a substitute for a documented risk assessment. Recalculate with conservative and severe assumptions to understand how sensitive the outcome is.
ROI = [(Baseline loss × Reduction × Years) − (Implementation cost + Annual cost × Years)] ÷ Total control cost × 100
Benefit-cost ratio divides avoided expected loss by total control cost. Payback uses implementation cost divided by annual avoided loss minus annual cost.
A positive ROI means modeled avoided loss exceeds control costs during the selected period; it does not guarantee realized savings.
Effectiveness is an assumption. Test conservative and optimistic values, and include operational costs that are genuinely incremental.
With $120,000 baseline loss, 55% reduction, $35,000 annual cost, $20,000 implementation, and 3 years: benefit = $198,000; cost = $125,000; net benefit = $73,000; ROI = 58.4%, benefit-cost ratio = 1.58×, and simple payback = 0.65 years.
Use attempts only if the probability and cost inputs are defined per attempt. Otherwise, filter the count to events matching the scope of the other assumptions.
Use a clearly documented range based on internal observations and expert review, then compare low, central, and high scenarios rather than presenting one value as certain.
Include them only when they can be estimated without duplicating another input. Otherwise, report them separately as unmodeled considerations.
No. A zero result only reflects one or more zero assumptions in this model and may indicate missing data rather than absence of risk.
No. It is a scenario estimate. Actual frequency, loss severity, recovery, and operational effects can differ materially from the inputs.
| Variable | Unit | How it is used |
|---|---|---|
| Baseline loss | USD/year | Expected loss without the proposed control |
| Loss reduction | Percent | Share of baseline loss expected to be avoided |
| Control costs | USD | One-time plus recurring spending |
| Analysis period | Years | Undiscounted evaluation horizon |
