A salary calculator is a tool that helps individuals estimate their potential earnings based on various factors. Users typically input information such as their job title, location, years of experience, and education level. The calculator then provides an estimated salary range, helping users understand what they might expect in the job market. These calculators can also factor in additional elements like bonuses, benefits, and taxes. By using a salary calculator, job seekers can make informed decisions about their career paths and negotiate better compensation packages when applying for jobs in their field.
