Startup cost: $200 - $2k

Setup costs for online arbitrage range from $200 to $2,000. The bare minimum would cover basic essentials like a computer, internet connection, and initial investment in products. On the high end, additional expenses may include subscription fees for sourcing tools, inventory purchases, advertising budget for product promotions, and professional seller account fees on platforms like Amazon. Essential costs at launch include sourcing tools to find profitable products, inventory for resale, and basic advertising budget. Optional expenses could include advanced software for product research and analysis. People often underestimate recurring fees such as subscription costs for sourcing tools and advertising expenses. Budgeting around $200 to $2,000 would be advisable for someone looking to take online arbitrage seriously and set themselves up for success.
