okay it’s easier for me to analyze if i annualize the numbers. 18k monthly revenue is 216k annual revenue. 15/hr is 30k/year (assuming a 2000 hour FTE year. it’s really 2080 but the math is so much easier at 2000) with four employees that’s 135k/yr. You’ve got 81k left for other expenses like food, cleaning supplies, advertising, legal bullshit and whatnot else that all comes out before you get to the owner’s cut.

the first two years of most businesses are where they fail. usually because they did not have enough cash on hand to cover two years of expenses when they opened, and it takes about that long on average for a business to break even.
