adding 40 amp 100 amp service

hi,
i'm adding a double oven to my kitchen that calls for a 40 amp breaker
be added to my 100 amp service

right now i have

6 20 amp breakers (kitchen, laundry, lights
4 15 amp breakers ( lights
1 50 amp (A/C

want to add (40 amp oven

the house is 1500 sq feet with gas cooktop, water heater, furnace and dryer

i did a load demand calculation and came up with 26,000va or
about 109 amps.. does this sound about right for the above

do i need to upgrade to 200 amp service

thanks in advance.. mooch

If your demand load is over 100 then yes, you should seriously consider an upgrade.
Don't bother with 150 amps. The cost difference between it and 200 amps is negligible.

Does this mean that your cooktop, furnace, water heater, and dryer are all gas? If so, I doubt that your demand is 109 Amps, unless I am missing something. If you want to have your service upgraded, more power to you (pun intended). It will eventually need to be done at some point I am sure, and will add value to your house. But if money is tight right now, I don't think it is absolutely necessary, even if you are adding an oven.
