Comparable cost basis

Every displayed period is rebuilt from the same daily EV and petrol assumptions so the daily, monthly, annual, and savings figures reconcile.

Calculate to see the selected market tariff and fuel-price basis.

EV consumption17 kWh/100km
Petrol consumption8 litres/100km
Monthly period30 driving days
Annual period365 driving days

Charging-price scope: charging type changes modeled time only. Every type keeps the selected market's residential tariff; public fast-charger fees, time-of-use rates, charger installation, and battery degradation are excluded. Full-charge cost includes the protected model's 10% energy buffer.

How the EV and petrol cost comparison is reconciled

The ledger applies the selected market's dated residential electricity tariff and petrol-price default to 17 kWh/100km for the EV and 8 litres/100km for the petrol vehicle. It calculates each daily cost first, then uses exactly 30 driving days for the monthly view and 365 driving days for the annual view.

Planning boundary: defaults come from the AfroTools country-energy dataset dated March 2026 and are not live quotes. Actual costs vary by vehicle efficiency, charging loss, public-charger fee, time-of-use plan, fuel price, traffic, weather, payload, and driving style.

Dated estimate

Dataset 2026-03. Not live pricing.

Check the assumptions

  • Confirm your tariff class, public charger fee, charger losses, and actual vehicle efficiency.
  • Compare with current petrol prices and your real daily distance.
  • Copy or download the result before choosing a vehicle or charger.

Limits

  • It does not include financing, battery degradation, maintenance, tolls, insurance, or charger installation.
  • COβ‚‚ estimates use a fixed grid factor and depend on actual grid mix and driving conditions.
  • No vehicle or trip data is uploaded by AfroTools.

Planning estimate only. Confirm live electricity and fuel prices before buying, quoting, or budgeting.
