On the Profit/Loss main screen, below the graph, your Money out total is displayed - which is included in the calculation for your profit or loss total.
Here's how
Your Money out total is the sum of your local currency withdrawals plus the local currency value of your crypto sends (as calculated when sent) - for all time.
Your local currency withdrawals are all the funds you’ve withdrawn from your local currency wallet to your linked bank account
Your crypto sends include all the crypto you’ve sent from external wallet addresses (which could have included a dynamic send fee, depending on network traffic), as well as any sends to a Luno wallet address (which includes zero fees)
