Well, to be fair, these numbers seem meaningless without any context. I'll give extreme examples. In DC, the median house price is near half million dollars, the mortgage on that can be around $3,000 month, and if you add in all the other costs, you could easily be spending $5K a month to maintain a household with all the modcons.
 
So if you offer to add an SB to your household, what counts towards the expectation? The total cost of the household, $5K? Perhaps just the marginal cost, which is to say, how much extra you will be paying to add one person to the household, for arguments' sake, let say $500?
 
Either way, this is a very different number than writing a $5.5K a month check to a SB.
 
So to me the universe of what SDs have to offer and what SBs wish to have would contain an almost infinite number of combinations, since it's all very subjective.

Check yourself, lady. There are sugar daddies in all social classes.

For my "Arrangement", my young friend is getting to live for free in one of the best neighborhoods in New York City. If he were sharing an apartment here with a room mate it would cost him at minimum $1,500 a month for his half of the rent on a one bedroom apartment and one of them would be sleeping in the Living Room not in his own bedroom. He is dining with us every night. ( helping to prepare meals three to four times a week). Food costs of at least $ 100 per week is another $ 400 of value he is getting. Plus we dine out a few times a week and invite him along. So the value he is getting here is a minimum $ 2000 a month. I have also handed over the credit card for reasonable shopping trips to H&M and Zara and helped fill a gap in College Tuition. I find all these costs perfectly comfortable in return for a valued friendship that I hope will last long past his exit from my home. There ARE some real people in real need on the site....but like everything you have to spend time and filter out the riff-raff.
