Set your sheet up with your monthly schedule on Sheet 1, zip code/region code
table on Sheet 2, and region code/summer & winter rates table on Sheet 3. I
am assuming that both tables have a title row.

Sheet 1 zip code entry cell is B1

Enter the following formula in Cell B3: =VLOOKUP(Sheet1!B1,Sheet2!A2:B50,2)
Adjust the A2:B50 range in the formula to match the range of your zip code
table.

Set up month labels in Column A starting with January starting in row 6.

Enter monthly usage in Column B corresponding to the labels.

Enter the following formula in Column C for winter months:
=VLOOKUP($B$3,Sheet3!A2:C50,3)

Enter the following formula in Column C for summer months:
=VLOOKUP($B$3,Sheet3!A2:C50,2)

Adjust the A2:C50 range to match the range of your region/rates table.

You can then multiply the two columns to calculate monthly cost.

Hope this helps...

I am trying to calculate the cost of electricity for a given customer by
entering the zip code they live in and the amount of electricty used. This
requires using information from the Utilities website, a zip code baseline
Territory chart and a Territory Rate chart. I have no problem downloading
each chart and storing locally if this makes it easier.

Information is organized so that all zip codes are in row A and each
teritory code in corisponding row B

The Territory Rate Chart has the Territory Code in row A then row B has the
coresponding Baseline quanity for summer and row C has the value for winter.

What kind of if statement do I need to write so that when a zip code is
entered and a month by month electricty usage is given it returns baseline
values so that i can compute cost of electricty?
