Please enjoy the use of this free gas estimator for contract deployment to the Ethereum blockchain.
Your use of this tool acknowledges that it's for estimation purposes only, the actual cost to deploy a contract will depend on the current gas and ether prices.
After you push your contract on Rinkeby (or other Ethereum testnet), go to your contract deployment transaction on https:// rinkeby.etherscan.io get the value of the "Gas Limit & Usage by Txn" field and paste it into the "Gas usage on testnet" field in this form. Then hit calculate.
