Retail Store Break-Even Calculator

Thinking about opening a storefront? This free retail store break-even calculator shows whether the numbers work before you sign a lease. Plug in your square footage and rent, your monthly fixed costs, and your revenue mix — vendor booth fees, commission on vendor sales, merchandise margin, workshops, and events — and watch the profitability dashboard, break-even math, and charts update live as you type. Stress-test the plan with what-if sliders (including “what if rent increases?”) and flip between Conservative, Expected, and Aggressive scenarios.

How the break-even calculator works

Enter your lease terms and the calculator converts annual rent per square foot into a monthly figure, adds your fixed expenses, and compares the total against four revenue streams: vendor booth memberships, commission on vendor sales, your own merchandise gross profit, and other income like workshops, events, and café sales. It then estimates the vendors needed to break even (each one brings a booth fee plus commission), the sales you’d need if commission were your only revenue, and your occupancy cost ratio — with a warning when rent starts eating an unhealthy share of revenue. Share links carry every value, and you can export your assumptions as CSV or JSON.

Frequently asked questions

What is a break-even point for a retail store?

Your break-even point is the amount of monthly revenue at which the store covers all of its fixed costs — rent, utilities, insurance, payroll, and everything else you pay whether or not a customer walks in. Below it you lose money every month; above it you profit.

How many vendors do I need to cover my costs?

In a shared retail or vendor-booth model, each vendor contributes a monthly booth fee plus a commission on their sales. The calculator counts both when it estimates how many vendors you need to break even, and shows how much of your expenses booth memberships alone would cover.

What is a healthy occupancy cost ratio?

Occupancy cost — rent plus NNN/CAM charges — should generally stay under 12% of total revenue for a healthy retail store. Between 12% and 15% deserves caution, and above 15% is a red flag: negotiate the lease, shrink the footprint, or grow revenue before committing.

Can I share my scenario with a partner or lender?

Yes. The Copy Share Link button produces a URL that carries every number you entered, so anyone who opens it sees exactly your scenario. You can also print the page, save it as a PDF, or download your numbers as a CSV for Excel.
