What is the NGO SRM ROI Calculator?

The NGO SRM ROI Calculator enables organizations to:
  • Quantify Security Risk: Calculate Expected Annual Loss (EAL) from historical incident data
  • Evaluate Investments: Assess the financial return of security risk management programs
  • Support Decision-Making: Provide evidence-based justification for security budgets
  • Enhance Transparency: Document assumptions and methodologies for auditability

Key Features

Built on ISO 31000 risk management principles with Expected Annual Loss (EAL) quantification consistent with FAIR, NIST, and other enterprise risk frameworks.
Supports multiple incident types including physical security, cybersecurity, health emergencies, and operational disruptions.
Delivers the Qualitative Impact Assessment workflow with checklist-based scoring and short evidence notes.
Calculates Net Present Value (NPV) and Return on Investment (ROI) over configurable time horizons (1-10 years).

Target Audience

This documentation serves multiple stakeholders:
  • NGO Security Managers: Primary users implementing security risk management programs
  • Finance Staff: Supporting budget justification and donor reporting
  • Field Operations Coordinators: Providing incident data and operational context
  • Auditors and Evaluators: Validating calculation methodologies and assumptions
  • Donors and Funders: Understanding the business case for security investments

Standards Compliance

The calculator methodology is grounded in established frameworks:

Prerequisites

Before you begin, ensure you have:
  • Historical incident data (≥12 months of security incident records)
  • Cost data (security-related budgets and procurement records)
  • Multi-stakeholder team (security, finance, operations representatives)
  • 2-3 hours for data preparation and analysis
Minimum Data Requirements: You need at least 3 incident types OR $5,000 total Expected Annual Loss (EAL) to produce credible results.

Step 1: Understand Key Concepts

The calculator uses four main metrics:

Expected Annual Loss (EAL)

Average annual financial impact of security incidents without intervention

Net Present Value (NPV)

Present value of multi-year security investment costs

Return on Investment (ROI)

Financial return as percentage of investment cost

Payback Period

Time required for benefits to recover costs (may be N/A)

Step 2: Gather Your Data

Incident Data

Collect historical security incidents with:
  • Incident Type: Specific category (e.g., “Vehicle Theft”, “Data Breach”)
  • ARO (Annualized Rate of Occurrence): Expected number of times per year (≥ 0; values above 1 indicate multiple occurrences annually)
  • SLE (Single Loss Expectancy): Cost per incident in USD
  • Notes: Context and data sources
ARO Calculation: Number of incidents ÷ Number of years observed Example: 3 vehicle thefts over 10 years = ARO of 0.30

Cost Data

Identify security-related costs by period:
  • Year 1: Initial investment (training, equipment, assessments)
  • Year 2-3: Ongoing costs (personnel, maintenance, renewals)
  • CAPEX vs OPEX: Capital expenditures vs. operating expenses

Assumptions

Define key parameters:
  • Discount Rate: Fixed at 0% in the calculator to maintain transparency; note any alternate rates separately if stakeholders request them.
  • Time Horizon: 3-5 years (match asset lifespan or planning cycle)
  • Qualitative Settings: Default weights (0.25 each), regression checkboxes, and improvement checklists; adjust weights only when priorities shift and record the rationale

Step 3: Use Data Templates

Download and populate the CSV templates:

Step 4: Import and Validate

  1. Upload CSV files to the calculator
  2. Address validation errors (common issues below)
  3. Enter assumptions manually
  4. Run calculation
  • ARO must be between 0 and 1: Convert percentages to decimals (30% → 0.30)
  • Period exceeds time horizon: Ensure cost periods ≤ time horizon years
  • Category is required: Provide descriptive names for all cost items
  • Weights must sum to 1: Adjust qualitative weights to total 1.0
  • Checklist incomplete: Either tick the regression box (score 0) or select improvement statements so the calculator can assign a score

Complete the Qualitative Checklists

  • Open each dimension (Access, Continuity, Acceptance, Wellbeing) in the Qualitative step.
  • Regression first: Tick the regression checkbox only when the situation deteriorated; it sets the score to 0 and disables the checklist.
  • Then tick improvements: Select every statement that happened in the past 12 months. Zero statements keeps the score at 1; each additional statement adds +1 up to 5.
  • Add a short note citing the log, observation, or data source that backs the selection.
  • Keep default weights (0.25 each) unless stakeholders explicitly agree to prioritise one dimension.

Step 5: Interpret Results

Understanding Your ROI

1

Review EAL

Your Expected Annual Loss shows the baseline risk without intervention. Higher EAL indicates greater potential for risk reduction.
2

Check NPV

Net Present Value of costs accounts for the time value of money. This is your total investment in present-day terms.
3

Analyze ROI

Positive ROI means benefits exceed costs. 100% ROI = benefits are 2× costs; 500% ROI = benefits are 6× costs.
4

Consider Payback

Payback period may be N/A if annual benefits don’t recover costs within the time horizon. This is normal for qualitative-heavy scenarios.

Example Results Interpretation

Sample Results

The results view begins with a narrative summary of qualitative impact and quantitative ROI. Expand the detail accordions for metric tables and qualitative notes.EAL: 49,250(annualriskwithoutintervention)NPV:49,250 (annual risk without intervention) **NPV**: 166,000 (present value of 3-year investment)
QII: 3.00 / 5.0
Financial ROI: −11.0% (discounted EAL benefits vs. costs)
Payback: N/A (financial benefits alone do not recover costs inside 3 years)
Interpretation: Quantified risk reduction alone does not recover the investment within three years. However, the Qualitative Impact Index shows strong improvements in access, continuity, acceptance, and wellbeing. Organisations should capture short evidence notes so improvements remain transparent even when quantitative ROI is negative.

Next Steps

Export Your Report

Generate PDF or Excel reports for stakeholder presentations and donor reporting.

Refine Your Analysis

Adjust assumptions (discount rate, time horizon, qualitative weights) and test sensitivity to key parameters.

Plan Implementation

Use results to justify security budgets and plan multi-year security programs.

Share with Team

Present findings to executive team and integrate into strategic planning.

Common Questions

High ROI typically indicates substantial benefits (risk reduction + qualitative improvements) relative to costs. Verify that incident costs include both direct and indirect elements, and that qualitative scores and weights match the evidence discussed.
Use industry benchmarks (GISF, INSO regional data) or expert judgment to estimate ARO/SLE for anticipated incidents. Document your assumptions clearly in the notes field.
Yes, include insurance premiums (e.g., K&R insurance) as OPEX costs in the relevant periods. This represents the cost of risk transfer.
The calculator fixes discounting at 0% to avoid devaluing future humanitarian outcomes. If stakeholders insist on an alternate rate, rerun the analysis externally and compare against the 0% baseline.
