There’s really no income cap with dropshipping. I’ve seen stores that make a few hundred dollars a month, and I’ve also seen stores doing $200k-$500k a month in revenue. It all comes down to how many sales you’re getting and how much profit you make per sale.
Some people sell high ticket products, so they earn more on each order. Others sell more normal products and might make around $20 profit per sale after costs.
So it mostly depends on your product, your margins, and your sales volume. On average, a lot of regular dropshippers end up somewhere around $1,000 to $5,000 a month.
