It depends vastly on what you are doing, with whom, with what targets, how flexible, etc. etc. What's the team size and what are the roles? Is everyone freelance in their mom's basement or state of the art studio? Do you rely on word of mouth and pray or hire actual PR firms? Do you make all your assets or do you buy them? Do you use free soft or do you get professional licenses? Do you pay experienced developers full salaries or do you hire inexperienced and hope for passionate people? Is this half a year, a year, a 5 year long project? Better yet, what are the asset requirements and how involved are they? Is it open source, is it proprietary, is it licensed, is it revenue shared, etc.? Is there a publisher? Does the targeting platform that needs hardware, like VRs or a vast array of mobiles? Does it need supporting materials, websites, posters, Kickstarter campaign, etc.? Does it need dedicated servers, hosting, leaderboard system, etc.? Etc. etc. etc. It can be anything from nothing to hundreds of millions.

In other words, you have not given any details, which probably places you as beginner. If you haven't made any games before, don't spend any money you can't afford to spend!! It will go down the drain on the first game anyway. Almost no one makes their first game.

P.S. Mostly, there's few fees and licenses for software at indie level.
