# 🔥 Gas and Banchmarks
2+
3+
This section will list the gas costs for every operation based on it's inputs.
4+
The way we decided how much gas will each and every operation consume was by checking how much time each operation takes in a QUERY. We decided to set the gas cost of `FHE.div` of `euint32` to be around 1 million gas units and set the price of other operations accordingly
5+
6+
:::tip
7+
The current gas limit for a tranasaction is set to be 50 million
