# Total Reserves

Reserves are an accounting entry in each bToken contract that represents a portion of historical interest set aside as [cash](/atokens/get-cash.md) which can be withdrawn or transferred through the protocol's governance.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](/atokens/reserve-factor.md).

**BErc20 / CEther**

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

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

**Solidity**

```
BErc20 bToken = BToken(0x3FDA...);
uint reserves = bToken.totalReserves();
```

**Web3 1.0**

```javascript
const bToken = CEther.at(0x3FDB...);
const reserves = (await bToken.methods.totalReserves().call());
```
