A microwave oven putting out 900 watts consumes around 1500 watts. One unit of electricity is 1 kilowatt-hour, so a 1500 watt appliance will use 1.5 kWh or 1.5 units. Electricity is about 7p per unit, so it will cost around 11p to run it continuously for 1 hour.

When you use the microwave you are using 900 watts. You have to know electric utility bill rate is for your location. For this example I will use 10 cents per kilowatt/hour.
(1) kilowatt is 1000 watts, 900 watts = 0.9 kw
(1) minute = 1/60 hour = 0.01667 hour
0.9kw x 0.01667 hour x 0.10 $/kw/hr = $0.0015 or 0.15 cents.
P.S. if you use your microwave during peak hours there could be a demand charge on each kw used.

Most people who own Ferrari's can afford the maintenance. Plus they generally do not drive them much. I would say your source was false.
