Be careful with this because it leaves the door open for the company to offer you the lowest salary. To say that your salary is negotiable suggests that you don't know how much you should be paid and are willing to accept anything. If you write “negotiable” on the request, be prepared to say the highest numbers when it comes time to discuss salary with a human being. Indicating your salary on an application is simple.
You can type the word or put a placeholder (for example, it's not too difficult during an interview either). All you have to do is say that you are willing to negotiate the salary when the hiring manager asks you: “What is your salary expectation? Follow up by letting them know that you understand that salary is more than compensation and that the amount in dollars you want may vary depending on the benefits available. On the other hand, offering them a salary that is too low will end your ability to get them to get a larger amount in the job offer phase. When you finally get to the point of asking for a larger sum, they'll wonder why you put such a low number on the request.
You might get them to get a little closer by saying something like: “In the application phase, you and I didn't know each other. Now that we have had time to better understand how well we will work together, I would like to try to increase the salary a little. All you have to do is say, “Is this salary negotiable? This simple four-word sentence opens the door to a conversation about the salary. Often, companies are hesitant to negotiate with job seekers because it's a wasted effort.
The job seeker will continue to say, “No, thank you,” even if the company increases the salary. They might even ask, “If we make you a better offer before the end of the week, will you start on Monday?” In this case, type “negotiable” or a similar phrase.
