Default Cost to get hot water from tankless coil in boiler

I had the tankless coil on the boiler disabled some years ago in order to install an electric water heater. Reason: at that time oil was expensive and electricity was cheap. Now both are expensive.

The 53-gallon electric water heater is now turned off to save electricity. I'd like to calculate the cost to get hot water from the tankless coil and compare this to other ways of getting hot water. How can I calculate this?

My average hot water need: about 5 gallons per day for one shower and washing dishes. About 15 minutes a day.
