The costs vary from site to site. Generally speaking, there are two categories of websites—the platforms with premium membership plans and the platforms with credits. Members who buy premium plans on sugar daddy sites spend from $40 to $120 per month, and on the sites with credits, a lot depends on your dating style—how many women you contact, the features you use, etc. The average cost of credit is $0,50, and most SDs spend about $100 a month on average.
