RestaurantMargin is a free restaurant profit margin calculator and menu-profit workspace. Enter each dish's ingredient cost, selling price and weekly sales to see food-cost percentage, contribution margin, weekly contribution, pricing targets and menu-engineering position before editing the menu. Contribution is not net profit; fixed costs, tax and other period expenses still need review.
The real menu
A busy restaurant can sell all night and still miss the item that is quietly taking margin off every plate.

One $2 move.
One real week.
If a dish sells 80 times a week, a small pricing or portion decision stops being small. The workspace makes that impact visible before you change the menu.
Run the numbersThe workspace
Enter the numbers once. See weekly contribution, food-cost drift, pricing targets and the menu-engineering position of every dish.

“We run five virtual brands, and the spreadsheet had become hard to trust. Now I can check the contribution margin for a dish without tracing formulas.”

“I use it before putting a special on the board. If the portion or price is off, I can see it while there is still time to change the dish.”

“I bring the export to our owner meeting now. Last month we removed two slow dishes and gave a better position to the ones people reorder.”

“I started with five tacos and then added the combos. Seeing the ingredient cost beside the selling price made the weaker combo obvious.”

“All three locations now use the same ingredient and labor fields. The weekly comparison no longer depends on whose spreadsheet I received.”
