I've been trying to implement a DApp to the mainnet of ethereum and I keep running into this problem :

We have loaded over a $1000 eth in the deploying contract. Is there any way I could calculate the gas needed because it's becoming quite expensive?

Any help would be appreciated.

Thanks and regards
