ROI of a technical alarm in agri-food: when it pays for itself

"How long until it pays for itself?" — the question every manager asks when shown an industrial technical alarm. Short answer: it depends on the value of what's inside and the incident frequency in your sector. Useful answer is a five-line calculation.

The simple model

ROI of a technical alarm:

ROI = (Avoided_loss × Annual_probability) / Alarm_annual_cost

Where:

Avoided_loss: what you lose in a typical incident the alarm would catch in time.
Annual_probability: probability of that incident in a year (expected frequency).
Alarm_annual_cost: hardware (amortized over 5 years) + support + IoT SIM.

If ROI is greater than 1, the system pays for itself in under 12 months.

Numerical cases by sector

Poultry farm with 22,000 layers

Avoided_loss from a ventilation failure: ~€18,000
Annual_probability: ~0.5 (one serious incident every 2 years)
Annual_cost: ~€1,200 (hardware €4,000 amortized 5 years + €200 support)
Expected annual loss WITHOUT alarm: €9,000
ROI: 9,000 / 1,200 = 7.5×

Pays itself in 1.6 months if the incident happens.

Cold storage with 18 t fresh meat

Avoided_loss from cold-chain discard: ~€50,000
Annual_probability: ~0.3
Annual_cost: ~€1,400
Expected annual loss WITHOUT alarm: €15,000
ROI: 15,000 / 1,400 = 10.7×

Pig farm, 24 farrowing sows

Avoided_loss from cold-induced piglet mortality: ~€6,000
Annual_probability: ~0.7 (frequent minor incidents in winter)
Annual_cost: ~€1,000
Expected annual loss WITHOUT alarm: €4,200
ROI: 4,200 / 1,000 = 4.2×

Dairy farm, 280 cows

Avoided_loss from tanker discard: ~€9,500
Annual_probability: ~0.4
Annual_cost: ~€1,100
Expected annual loss WITHOUT alarm: €3,800
ROI: 3,800 / 1,100 = 3.5×

What the model does NOT capture

These numbers are conservative and only count direct loss. They do NOT include:

Loss of premium customer after an incident (6-12 months out, often bigger than the direct loss).
Contractual penalties with integrators or co-ops.
Cost of an unplanned health audit.
Human stress and internal reputation.

Actual ROI is typically 2× to 3× the model output.

When it doesn't pay off

Some cases where ROI doesn't justify it:

Very small operation with little product at stake (<€5,000).
Non-critical processes where a 4-6 h failure doesn't generate real loss.
Operations with 24/7 staff that visually catches any deviation.

For everything else — and especially any operation delivering to a professional buyer — ROI is yours in under a year.
