First, know or choose which Tech Stack you will use for development. This will have a big impact on the number of developers you need. For example, if you use JavaScript, you will probably need fewer developers than Ruby or some other complex tech stack. Learn why not to use Ruby as a Tech Stack here!

Don't forget that the most important thing in all this is to make your budget work, you can find out the values of devs in JavaScript on sites like Glassdoor.com.

2nd: The phase of the project affects the number of developers you need: You may need a few developers to build a prototype or Minimum Viable Product (MVP); this also depends on the maturity leaps of your product. Here is a visual guide to this roadmap.

3rd: Also, how long will it take you to complete it? If this time is due to a deadline for your product or customer, you should estimate it.

Finally, use the above variables to calculate the number of developers you need:

If you have a total budget of 100,000 USD; the average salary of a developer in your region is 50,000 USD; and you plan to work 40 hours per week:

DevsNumber = ($100,000 / $50,000) / 40 = You would need 2 Devs

But is this realistically achievable? To make it more accurate, add the Features and Maturity Jumps amount, the Sprint X-ray (How will you distribute the load according to your dev's role & seniority?), and the confirmed current Glassdoor Tech Stack Dev's Salary ranges in your region...
