Methodology - Stress Test Model

Calculates the Sustainability Horizon (τ) based on the economic impact of rising resource costs.

1. Extra Annual Cost (ΔC):
ΔCi(t) = Σ [ui,r × (cr(t) - cr(b))]
2. Projected Profit (P):
Pi(t) = Pi - ΔCi(t)
3. Sustainability Horizon (τ):
τi = min(t - b)
where ΔCi(t) ≥ Pi

The calculation is made for each resource separately. 140+ means the company does not reach zero profit within the available 2026–2100 projections.

The projection sliders set a resource cost growth rate g. On a straight price path the cost at any year scales with g, so the horizon scales with 1/(1+g). That is an extrapolation on top of the table, not a figure from it.
