Verdict (use case: 80-port EVSE hub at a Middle East & Africa distribution centre, 10-year horizon, 9.00% discount rate, evidence date 2026-09-22). The hub is finance-positive on a discounted-cash basis. computed figures from the scenario model: NPV = USD 692,295.05; IRR = 22.06%; simple payback = 3.86 years; discounted payback = 4.97 years; PV of costs = USD 2,002,222.72; PV of benefits = USD 2,694,517.76; TCO per km — EV = USD 0.1093; TCO per km — ICE = USD 0.3340; savings per km = USD 0.2247; savings over horizon = USD 6,291,800.00. Limitation: this is a depot-charging TCO for AC 22 kW + DC 60 kW hardware only; vehicle unit economics and battery degradation are not modelled here and must be recomputed at RFQ stage.

Discounted payback of 4.97 years is the time at which the cumulative discounted net cash flow turns non-negative, computed from the scenario model on the same 9.00% basis as PV of costs and PV of benefits above.
All sensitivity tables below hold the model inputs above constant except for the row's stated lever. Both cost and benefit legs are discounted at 9.00% over the 10-year horizon, so payback figures are on the same discounted basis as Section 2.
