# What are bands in CurveUSD?

In CurveUSD protocol, each band represents a price range (calculated by the protocol) at which the amount of collateral in that band can be liquidated if the oracle price reaches it.<br>

The number of bands can go from 4 to 50, and the width of each one is determined by the Amplification parameter - A.<br>

Formula: `1/A * coll_price`\
Example: A = 100, 1 ETH = $2000 -> Band width = $20.

However, band width isn't fixed as each band uses its collateral price in the calculation.

Choosing a bigger number of bands gives you a wider price range for liquidation, but increases the chances of higher loss (**`LINK`**) during soft liquidations (and gas costs).
