If I use the Wi-Fi for my ipad i have at home for my iphone does it cost extra?

It shouldnt, i don't think

No it does not cost anything extra other than what you are paying for that Wi-Fi signal. Your phone using the Wi-Fi signal does not add any extra cost. I have friends that use their home Wi-Fi connection to cut down on their data being used through their cellular network. Surf as much as you want through your Wi-Fi network. No worries.
