Home charger payback
How many months until a wallbox pays for itself versus charging those home miles on public rapid chargers? Uses the same energy defaults as the running-cost calculator.
Energy-only payback. Ignores standing charges, charging losses, convenience, and any grant or tariff signup bonus. Wallbox cost is your figure — the £999 chip is a labelled UK example (Ohme Home Pro / Pod Point Solo 3S “from £999 with standard installation” as reported by UK charger guides in Oct 2026), not a quote for your driveway.

Miles & mix
Payback compares: those home-share miles at the home rate vs the same miles at the public rate. Miles you already charge publicly do not help the wallbox pay back.

Maths: pence/mi = p/kWh ÷ mi/kWh. Monthly saving (£) = (public p/mi − home p/mi) ÷ 100 × (miles × home%). Months = wallbox £ ÷ monthly saving.
