Why most vendor ROI calculators are worthless
Three structural failures recur:
- Single-point estimates with no sensitivity analysis. The procurement team cannot stress-test the assumptions.
- Inflated safety values — claiming a fall prevention figure based on a 1990s OSHA average rather than real KSA Aramco contractor data.
- No compliance line item — the PDPL audit pack and IKTVA scoring are real cost-and-benefit categories that vendors ignore.
A defensible calculator addresses all three.
The four input categories
A 2026 calculator takes inputs from:
- Operational: production hours, downtime per incident, throughput per hour.
- Safety: incident frequency, severity, lost-time-injury (LTI) cost.
- Security: theft rate, asset value, intrusion-incident cost.
- Compliance: PDPL audit cost, IKTVA scoring uplift, regulatory penalty exposure.
Each category gets a high/mid/low estimate, not a single number.
Operational variables
The operational lever is downtime reduction and throughput uplift. Variables:
| Variable | Typical KSA range |
|---|---|
| Production hours per year | 6,000–8,400 |
| Downtime cost per hour | SAR 8,000–80,000 |
| AI-attributable downtime reduction | 5–15% |
| Throughput uplift from automation | 1–4% |

Safety variables
The safety lever is incident reduction. Variables:
| Variable | Typical KSA range |
|---|---|
| LTI rate per million man-hours | 0.4–1.8 |
| Average LTI cost (medical + lost time) | SAR 60,000–250,000 |
| AI-attributable LTI reduction | 15–35% [VERIFY-SME] |
| Severe-incident cost (one event per 5–10 years) | SAR 1.5M–8M |

Security variables
The security lever is theft reduction and intrusion prevention. Variables:
| Variable | Typical KSA range |
|---|---|
| Tool theft rate per year | 6–9% of inventory value |
| Tool inventory value (1,000-tool site) | SAR 2.5M–6M |
| AI-attributable theft reduction | 60–80% |
| Intrusion-incident cost | SAR 50,000–500,000 |

Compliance variables
The compliance lever is regulatory readiness. Variables:
| Variable | Typical KSA range |
|---|---|
| PDPL audit cost (per cycle) | SAR 80,000–250,000 |
| IKTVA scoring uplift on a SAR 5M contract | 0.5–2% [VERIFY-SME] |
| Aramco contractor scorecard impact | Variable, often binary |
| Regulatory penalty exposure (PDPL Article 35–37) | up to SAR 5M [VERIFY-SME — confirm against current regulation] |

Cost inputs — the realistic 2026 KSA pricing
Defensible cost inputs:
| Item | SAR per year |
|---|---|
| CCTV retrofit per camera | 1,200–3,500 |
| Edge inference per 8-camera cluster | 18,000–32,000 |
| Software licence per camera | 600–1,800 |
| Integration (Year 1, one-off) | 80,000–250,000 |
| Annual operations + tuning | 25,000–60,000 |

Payback maths
A simple payback formula:
Payback (years) = (Year 1 CapEx + Year 1 OpEx) / Annual Net BenefitWhere Annual Net Benefit = (operational + safety + security + compliance benefit) − (recurring cost).
For a 200-camera mid-size plant in 2026, typical ranges:
- Year 1 CapEx + OpEx: SAR 600,000–1,400,000
- Annual Net Benefit (mid case): SAR 800,000–2,500,000
- Payback: 0.6–1.7 years

The sensitivity analysis
A defensible calculator outputs three scenarios:
- Pessimistic: low-end benefits, high-end costs.
- Mid: midpoint of every range.
- Optimistic: high-end benefits, low-end costs.
If the pessimistic scenario does not break even within 3 years, the deployment is fragile. Procurement teams should pause.
Building the calculator — practical steps
- Spreadsheet template — Google Sheets or Excel with named ranges per variable.
- One row per camera cluster so partial deployments can be modelled.
- Three columns per benefit for low/mid/high.
- Sensitivity heatmap showing payback under variable shifts.
- Documentation tab citing the source for each input.
Owners typically maintain this calculator in finance, with HSE and security feeding inputs.
Common calculator mistakes
- Counting deterrence as zero. A theft prevented is not visible in the books, but the calculator must include it.
- Double-counting safety and security. The same incident should not appear in both buckets.
- No discount rate. Multi-year benefits should be NPV-discounted at the corporate rate.
- Ignoring PDPL cost — both the audit cost and the penalty exposure are real numbers.
How to use the calculator in procurement
- Build the calculator before vendor RFPs.
- Ask each vendor for inputs to your calculator, not for their own ROI.
- Run the sensitivity analysis on each vendor’s claimed performance.
- Compare net present value, not Year 1 cost.
