How to Estimate Proceeds From Selling a Taxed Token

To estimate what a taxed token sale will return, start with the swap quote, then account for the token’s sell fee, price movement and network cost. The fee is set by the token issuer, Uniswap Labs says, and can apply when you sell or transfer the token.

A quote shows the route’s expected output, but the amount credited can differ if the contract deducts a fee during the sale. For how Blackhole Swap routes trades through pools, see the article on its routing and pool liquidity.

How do you estimate the amount after tax?

First check whether the stated sell fee applies to the tokens sent or to the output. If a contract charges a 5% fee on the token amount sold, for example, 100 tokens would leave 95 tokens for the swap before the pool’s price calculation; that is an illustration, not a quote for any specific token. The contract’s fee rules determine the actual basis and rate.

Then use the swap screen’s expected output as the starting point. Uniswap Labs says its interface displays swap details, network cost, route and minimum output; compare those fields before signing. If the fee is already included in the displayed estimate, do not subtract it again.

What can make the final proceeds lower?

The sale fee is only one deduction. Uniswap Labs describes slippage as the difference between expected output and the amount available when the transaction executes; price impact can also reduce a quote when the trade is large relative to pool liquidity. Network cost is separate from the token fee and is paid for processing the transaction.

• Sell fee: Check the token’s current sell-fee rate and whether it can change. Uniswap Labs notes that variable fees may require a higher slippage setting.
• Minimum output: Read the minimum received shown in the swap details. This is the lower bound accepted by the transaction under its slippage setting.
• Network cost: Include the displayed transaction cost when estimating the overall value you keep.

How should you choose a slippage setting?

Set it high enough to cover the token’s fee and plausible price movement, but avoid raising it blindly. Uniswap Labs warns that a fee increase can make a transaction fail if the slippage limit is too low; a larger limit also permits a worse execution price. If the fee is unclear or the estimate changes sharply, review the contract’s fee information and refresh the quote before signing.
