Publishing in low-cost journals is a good option, especially if you’re working with limited resources. However, it's essential to ensure the journal is reputable, indexed, and recognized in your field. Here's how you can identify low-cost yet legitimate journals: 

The ABCD Index, or Academic Business Current Data Index, is indexing platform that categorizes journals across various academic fields. Journals indexed by ABCD are divided into four categories—A, B, C, and D—based on factors such as review quality, research impact, and relevance. "A" category journals are typically high-impact and well-regarded, while "D" category journals are generally less prestigious and may lack rigorous peer review standards.  

Here's a categorized list of journals across various disciplines:

• International Journal of Scientific Research and Engineering Trends (IJSRET): This is a peer-reviewed open-access journal that publishes research in engineering, science, and technology.
• International Journal for Research Trends in Social Science and Humanities (IJRTSSH): This journal has and focuses on research in social sciences and humanities.  
• International Journal of Science, Engineering and Technology (IJSET): This journal is indexed by several platforms, including ABCD-Index, Crossref, Academia, CiteFactor, Google Scholar, and Publons. 
• The International Journal for Novel Research in Economics, Finance, and Management (IJNREFM) is an online, open-access platform dedicated to publishing scholarly work in the fields of finance, economics, accounting, business, marketing, and management
