# Total Reserves

Reserves are an accounting entry in each aToken contract that represents a portion of historical interest set aside as [cash](https://docs.agilefi.org/atokens/get-cash) which can be withdrawn or transferred through the protocol's governance. A small portion of borrower interest accrues into the protocol, determined by the [reserve factor](https://docs.agilefi.org/atokens/reserve-factor).

**SErc20 / SEther**

```
function totalReserves() returns (uint)
```

* `RETURN`: The total amount of reserves held in the market.
