A master’s degree can take you straight into work. It can also take you toward a PhD. Many graduates reach this fork and are not sure which way to go.
A PhD is a research degree. You spend several years studying one topic in depth and produce original work that adds to your field. A master’s is shorter and broader. It teaches you to apply existing knowledge. A doctorate asks you to create new knowledge. That difference shapes how you spend your days and which jobs open up afterward.
People usually pursue a PhD because they want to do research. Some aim to teach at a university. Others want senior research roles in industry, government, or nonprofits. About 2 percent of American adults hold a doctorate, so it is an uncommon credential. Before you apply, think hard about whether you need one. A PhD can raise your earnings in some fields, but plenty of rewarding jobs never require it.
Money matters. Many full-time PhD programs cover tuition and pay a stipend through teaching or research assistantships. Many do not. Work out the full cost before you commit, including living expenses and the income you give up while you study.
The application itself is demanding. You will need transcripts, a statement of purpose that explains your research interests, and letters from people who know your academic work. The most important step is contacting potential supervisors early. A supervisor whose research matches your interests is the single biggest factor in a good doctoral experience. Read their recent papers before you write to them.
You do not have to start right away. Work experience can sharpen your research questions and make your application stronger a year or two later.

Strong mentoring helps at every stage, and these tips for succeeding in online learning apply if you study remotely.
