Actually, the calculation is independent of what amount of electricity or propane you use.
The spreadsheet that I use to determine if I should use propane or electricity for heating etc. shows that the "break even" value at electricity at 18 cents/KWH for propane is about $2.40 per gallon. This assumes 100% efficiency for electric and 50% efficiency for propane. If the electricity is more expensive, run propane if it's $2.40 or cheaper. The 50% efficiency number is a guess, any higher then propane wins at a lower value
