An interactive economic model of a toll-road concession — watch cars and HGVs flow under the toll gantry, see the light-vehicle and heavy-goods revenue split, and run the investment case live.
A toll-road concession owns the tarmac, and charges every vehicle that uses it. The cost base — resurfacing, patrols, insurance — is almost entirely fixed, so once the road is built, every extra vehicle is nearly pure margin. The whole investment case turns on traffic (vehicles per day), the toll tariff, and the heavy-goods mix — HGVs pay roughly 3× a car for the damage they do.
Year-1 financials flow live from the simulation above: revenue £0 and EBITDA £0 p.a. Set your deal terms below — the unlevered IRR (asset return) and levered IRR (return to equity, after debt) recompute instantly.
Illustrative model. Represents a tolled inter-urban motorway concession. Revenue = traffic × toll, where heavy goods vehicles pay a multiple of the car toll, plus modest roadside/services income. Operating costs (pavement resurfacing, routine O&M and patrols, tolling & collection, insurance and a revenue-linked concession fee) are dominated by fixed maintenance, with only the tolling cost and the concession fee scaling with volume — so each extra vehicle is overwhelmingly incremental margin and traffic drives the result. EBITDA = revenue − operating costs; excludes upfront construction/acquisition capex. The investment case is a simplified DCF. For illustration only — not investment advice, and not any specific asset.
