Before opening a cafe, convenience store, or similar shop, enter your monthly fixed costs and your average sale price with cost ratio (or variable cost per sale) to find the break-even revenue and sales count where you neither profit nor lose money. Add a target monthly profit to also see the revenue you'd need to reach it.
Add anything else you pay every month regardless of sales — loan interest, insurance, franchise royalties, etc.
The actual number of days you're open, excluding closed days. Defaults to 30 but is fully editable.
If entered, also calculates the revenue and sales count needed to reach this profit.
Enter the details above to calculate the result.
Break-even revenue = monthly fixed costs ÷ contribution margin ratio (1 − cost ratio). Break-even sales count = break-even revenue ÷ average sale price. This calculator uses only the fixed costs, price, and cost ratio you enter — it doesn't rely on any year-specific statistics or rates, so it stays valid no matter when you use it. When actually opening a business, also factor in upfront costs like interior work and key money, seasonal sales swings, and taxes — and consider a market analysis and professional consultation for an accurate feasibility assessment.
The break-even point is the sales level at which a business's revenue exactly covers its costs — below it you're operating at a loss, above it you're profitable. This tool calculates the break-even sales amount and transaction count for a small business like a cafe or convenience store, based on your fixed monthly costs and per-sale economics, plus the sales level needed to hit a specific profit target.
The core concept is contribution margin ratio (1 − variable cost ratio), which represents the portion of each sales won that's left over after variable costs to help cover fixed costs. Break-even sales = fixed costs ÷ contribution margin ratio, and break-even transaction count divides that by your average transaction value; if you enter a target profit, the calculator adds that profit figure to fixed costs before dividing, treating your desired profit as an additional cost that also needs to be covered by sales.
