The rent goes out every month — how many customers does it take to cover it?
One of the most commonly overlooked calculations for retail owners is the "minimum daily sales needed to cover rent." Rent and common fees drain out on a fixed schedule regardless of how sales go, yet few owners ever work out exactly how many customers a day it takes to earn that money back. Without knowing this number, you can end up in the trap of "business feels busy, but why is there nothing left over?"
This calculator adds up your rent and other fixed costs, divides by your margin rate to get the monthly revenue needed to break even, then divides by 30 to find the minimum daily revenue. Apply your average ticket size on top of that, and you get a concrete answer for how many customers need to walk in each day to cover rent. For example, a store with $3,000 rent, $2,000 in other fixed costs, and a 30% margin needs about $16,670 in monthly sales to break even — roughly $556 a day.
Once you have that number, you can set a concrete target by comparing it against your store's actual average foot traffic. If actual visitors fall short of the required customer count, consider a combo menu or upsell strategy to raise your average ticket size; if traffic is fine but margin is low, it's time to re-examine your cost structure. Running this calculation before signing a lease also makes comparing candidate locations far more realistic.

Divide the minimum daily revenue by your average ticket size (average payment per customer) to get the number of customers you need each day to break even.
Beyond rent, add in common area fees, minimum payroll, utilities, and insurance — any expense that recurs monthly regardless of revenue — for the most accurate figure.
