# Gas Costs

The gas usage of the protocol functions may fluctuate by market and user. External calls, such as to underlying ERC-20 tokens, may use an arbitrary amount of gas. Any calculations that involve checking [account liquidity](/comptroller/get-account-liquidity.md), have gas costs that increase with the number of [entered markets](/comptroller/enter-markets.md). Thus, while it can be difficult to provide any guarantees about costs, we provide the table below for guidance:

| Function         | Typical Gas Cost                     |
| ---------------- | ------------------------------------ |
| Mint             | < 150K, aUSDC < 300k                 |
| Redeem, Transfer | < 250K if borrowing, otherwise < 90K |
| Borrow           | < 300K                               |
| Repay Borrow     | < 90K                                |
| Liquidate Borrow | < 400K                               |
