# Withdrawal Fees

A user can earn arbitrage profit by performing a swap and withdrawal followed by a reverse swap on a token with liquidity ratio < 1. Thus the withdrawal fees is only charged for tokens where the liquidity ratio < 1.

The arbitrage fee is given by:

$$
\text{Withdrawal fees} = (L-W)(f(r\_2)-f(r\_1))
$$

​Here,

*L = Deposits made by LPs in the stablecoin*

*W = Withdrawal Amount*

*f(r) = Slippage function*

*r\_1 = Liquidity Ratio before deposit*

*r\_2 = New liquidity ratio after deposit*

Withdrawal fees can become significant when liquidity ratio is low and NLR < 1. Thus, users are also allowed to withdraw in other tokens whose liquidity ratio > 1. Withdrawing in other tokens does not incur any fees for the user except a nominal swap fees.
