MIZAN · Free energy comparison

Petrol, electric or plug-in hybrid?

Compare energy costs using your own driving, consumption and prices. Free, without an account or live price feeds.

Your driving and prices

Energy cost only — not total ownership cost.

Purchase price, depreciation, finance, insurance, maintenance, charger installation and fixed fees are not included. Annual cost assumes the same monthly driving and prices for 12 months.

Runaki, household tiers or generator charging?

Use the actual extra cost of charging, not an assumed national price or an average household rate. This tool does not apply a Runaki tariff automatically.

For a tiered bill, compare the bill with charging and without charging over the same billing period. Divide the difference by the extra kWh drawn by charging in that period. If energy sources differ, use a representative extra rate for your charging mix.

Extra IQD/kWh = (bill with charging − bill without charging) ÷ charging kWh

External website; check the billing period and tariff there.

Charging loss is the percentage of energy drawn from the charger that does not reach the battery. At 10% loss, 18 kWh at the battery requires 20 kWh from the charger.

Start with your own numbers.

Your comparison will show energy cost per 100 km, per month and per year. Nothing is calculated from an assumed national price.
