# Calculator
When preparing to mint or execute a conccurential action, it's important to anticipate the gas fees you're ready to pay. Aura offers a feature that allows you to accurately forecast this, taking several parameters into account. This feature can be used with /gas calculator.
### Select your gas settings
This feature uses several parameters to give you an accurate estimate of the fees you will pay. Keep in mind that it works for any type of token, coins and NFTs. The bot has five entries to fill in to provide an answer :
* **Price:** the mint, presale or mint price for a single token.
* **Quantity:** the amount of tokens to buy.
* **Gas limit:** the limit of gas unit limit to use.
* **Max gas fees:** the maximum gas fees to use.
* **Max priority:** the maximum priority fees to use.
### Fees estimation
The bot returns a table with various Autres of your gas expenses, such as the total price range you'll pay, the price range you'll pay per token, and the price at which you'd have to sell each token to break even, including gas fees.
Also, the answer contains a button enabling you to copy the table and retrieve it easily. It's a great way to share your gas setting with your group.
