What do you pay for 16 kiloWattHours?
16 kWh isn't very expensive. For example, assuming you live in Utah, the cost per kWh is around 4.5 cents, as opposed to elsewhere where the costs run closer to 6.5 cents.
So, 6.5 cents x 16 = $1.04
Multiply 16KWH by $/KWH and you will get your answer. The price per KWH is different all over the country. Where I live it’s $0.11/KWH. So for a full charge 0.11 x 16 = $1.76.
