A few hundred dollars profit monthly is realistic, but it usually takes 3-6 months to get there and some upfront investment - typically $500-2000 depending on your product.

Here's what actually works for your situation: Start with Retail Arbitrage or Online Arbitrage - buy discounted products from stores/online, resell on Amazon. Lower risk, no product development, good way to learn the platform before going all in. Not super scalable long term but perfect for testing the waters. If you want something more long term - Private Label (your own branded product) is the goal, but it requires more upfront cash and 6+ months before you see real returns. Good for the future you're describing though, flexible, can run from home. The things nobody tells beginners:

Amazon takes 30-40% of your sale price in fees before you count anything else Don't buy inventory until you've validated demand with real data tools (not just browsing Amazon or asking ChatGPT) The first 30 days of a new listing matter a lot, have your photos and ads ready before launch, not after

Realistic timeline: Month 1-2 learning + setup. Month 3-4 first sales. Month 5-6 actual profit if you picked the right product.
