The amount of money that laundromat owners make per year per laundromat is around $30,000.00 to $100,000.00 per year depending on the size of the laundromat and how busy the laundromat is.
If the laundromat is in a less busy location then you might only earn $20,000.00 to $30,000.00 per year after all the expenses are taken into account.
If the laundromat is in a very busy location and you own more than one really busy laundromat then you could earn $200,000.00 to $500,000.00 and sometimes more.
The average laundromat owner earns around $30,000.00 to $50,000.00 per year which is on par with an average minimum wage salary job in some places.
Owning a laundromat is a pretty good passive income source though because laundromats will always be in demand as long as people wear clothes and need to wash them.
