How much money does it take to run a baby store for one year?

There are too many variables to get a definitive answer to that kind of question. For instance, how large will the store be? This will determine how much you'll pay for lease/rent. Also, what items will you be selling in the store? How many people will you be hiring? Will you be advertising? What will you need to equip the store itself (shelves, racks, tables, etc.), or will you be operating in a place that was already a store and has some or all of that? There are also taxes, insurance and I'm sure a few things I might have overlooked. All these would be part of what it costs to run the store.
