Calculation doesnt work

Account balance = 107000. When the user inputs 106500 it will give the else statement. Any ideas how to fix this?

while (menuChoice == 1) {                   

            System.out.println("How much do you want to transfer?");
            transferAmount = console.nextDouble(); // Getting transfer amount
                                                // from user input
            System.out.println("Who do you want to transfer this to?");
            transferName = console.next(); // Getting a transfer name from user input
            accountBalance = (accountBalance - transferAmount); // The calculation for account balance

            if (accountBalance > transferAmount) { // Only allowing transfer if the transfer amount is less than the account balance
                System.out.println(""); // spacing out the output
                System.out.println("Transfer Complete");
                outfile.println("The balance for the port account is £"+ accountBalance + "  You have sent £"+ transferAmount + " to " + transferName+ "  on the following date and time,  " + Date); // Printing line to output file about the transaction details
                outfile.close();
                menuChoice = 0; // Ending the while loop if true



            } else  // Denying a transfer if the transfer amount is more than the account balance
                System.out.println("Warning You will go overdrawn!");
            menuChoice = 0;

        }
