The dog park bar model layers three revenue streams: recurring memberships for park access, day passes for drop-ins, and high-margin bar and food sales while guests are on site. Memberships and day passes carry almost no cost of goods, so they fall close to pure margin, while bar and food revenue is reduced by its cost of goods (the COGS input).

Monthly profit is total revenue minus bar and food cost of goods minus your fixed monthly costs (rent, staff, utilities, insurance). Break-even members shows how many memberships you would need for profit to reach zero, holding your day pass and bar assumptions constant. Because bar sales and day passes often cover most of the fixed costs, the break-even membership count is usually lower than owners expect, which is exactly why the recurring membership base is where the profit compounds.
