Are fees decductible from gains? Are capital gains from api integrations with fees?

I connected my coinbase account here and imported my transaction history and it reports a gains number. I don’t understand if that number factors in fees I’ve paid to the platform for those trades, and if it doesn’t if I should go calculate that to reduce my capital gains amount.

Any help appreciated.

I have the same question. @Chandan please reply ! Are fees paid included in the cost basis?

@Chandan I am also seeing that exchange fees are not being deducted from gains, is that correct? It looks like this problem has existed for at least two years, do you guys have a timeline to account for exchange fees in your reporting?
