My house as an example: 1700 gallons x $3.80 = $6460. This winter I burned $2100 in coal (and was warmer ), so I saved $4360.
That's how I do it except my numbers are quite as high. 800 gllons x $3.80= $3040. I burned $900.00 in coal. So I saved $2140.
And another significant factor that must be considered is the comfort level. While saving 2k the house is MUCH warmer.
