Board-Ready Summary
Recommended annual cybersecurity budget: $1,329,167 (average of three methods). Industry benchmark for tech: 8.5% of IT spend ($850,000). Security maturity is average — budget aligns with industry peers. No prior incidents — proactive investment recommended to maintain posture.
Justifying a security budget to a board is easier when three independent methods converge on a number. This calculator computes a recommended annual cybersecurity budget as a percentage of IT spend, on a per-employee basis, and as a risk-based share of revenue, then averages them and benchmarks the result against industry norms with a board-ready summary.
Formula
Budget = average(itBudget × pct%, employees × perEmp, revenue × revPct%) × adjustmentFactor
- pct%
- Industry security spend as a share of IT budget (e.g. finance 10%, healthcare 7%, education 4.5%)
- perEmp
- Industry per-employee security spend (e.g. finance $3,500, healthcare $2,800)
- revPct%
- Risk-based revenue share, equal to pct% × 0.15
- adjustmentFactor
- maturityAdj × (1 + 0.05 × compliance) × (1 + 0.10 × priorIncidents)
How it works
- Enter annual revenue, IT budget, employee count, industry, security maturity (1-5), the number of compliance requirements, and prior incidents.
- A single adjustment factor scales every method: maturity below 3 multiplies by 1.3 (above 3 by 0.9), plus 5% per compliance requirement and 10% per prior incident.
- Three methods are computed — industry % of IT budget, per-employee spend, and a risk-based percentage of revenue — then averaged and split into an allocation (40% people, 25% tools, 20% services, 10% training, 5% incident reserve).
Worked example
A healthcare org with $50M revenue, a $5M IT budget, 500 employees, security maturity 3, two compliance requirements, and one prior incident.
- Adjustment factor: 1.0 (maturity 3) × 1.10 (2 × 5%) × 1.10 (1 × 10%) = 1.21.
- Method 1: $5M × 7% × 1.21 = $423,500. Method 2: 500 × $2,800 × 1.21 = $1,694,000. Method 3: $50M × 1.05% × 1.21 = $635,250.
- Average the three: ($423,500 + $1,694,000 + $635,250) ÷ 3 = $917,583.
Recommended annual budget ≈ $917,583, versus the unadjusted industry benchmark of $350,000 (7% of the $5M IT budget).
Frequently asked questions
- Why use three different budgeting methods?
- No single method fits every company. Percentage-of-IT works when IT spend is well defined, per-employee scales with headcount, and risk-based ties to revenue exposure. Averaging them produces a more defensible figure that does not over-rely on one assumption.
- What is a typical security share of the IT budget?
- It varies by sector. This tool uses benchmarks of roughly 10% for finance, 8.5% for tech, 7-7.5% for healthcare and government, and 4.5-5.5% for education, retail, and manufacturing, reflecting differing regulatory and threat pressures.
- How should I allocate the budget across categories?
- The default allocation is 40% to people and staffing, 25% to security tools and software, 20% to managed services and consulting, 10% to training and awareness, and 5% to an incident-response reserve. Adjust based on whether you build or buy capabilities.
- Does the calculator account for security maturity?
- Yes. Organizations below maturity level 3 get a 1.3× uplift to close gaps, while those at level 4 or 5 get a 0.9× factor since they need less catch-up investment. Compliance requirements and prior incidents add further uplift.
