What this calculation means
Menu-price rounding moves an already calculated price to a chosen price increment. The selected rule decides whether to use the nearest point, an upward point, or a downward point.
For the nearest rule, an exact positive halfway point rounds upward. A rounded zero price cannot have a defined food-cost percentage.
How to use this calculator
Enter the calculated price and a positive increment. Choose a rounding rule. Optionally enter ingredient food cost to see its percentage at the rounded price.
Formula and variables
Rounded price = Increment × selected rounding(Calculated price ÷ Increment); Food-cost share = Food cost ÷ Rounded price × 100
- Calculated priceUSD
- Price before rounding.
- Price incrementUSD
- Price step, such as 0.50.
- Food cost (optional)USD
- If supplied, the food cost percentage is recalculated after rounding.
- Rounding rule
- Choose how the calculated price moves to the price increment.
The selected rule applies to the entered increment first. The resulting price displays to cents. The optional ingredient ratio uses that rounded-increment price.
Understand your result
The primary answer is the chosen price point. When food cost is supplied, the additional percentage uses that rounded price.
Worked example
Round a $12.4667 selling price to the nearest $0.50. Ingredient cost for the item is $3.74, excluding packaging.
Calculated price: 12.4667 USD
Price increment: 0.5 USD
Food cost (optional): 3.74 USD
Rounding rule: Nearest
- Divide the entered $12.4667 price by the $0.50 increment = 24.9334.
- The nearest whole increment is 25; 25 × $0.50 = $12.50.
- Ingredient food-cost percentage at the rounded price = $3.74 ÷ $12.50 × 100 = 29.92%. Packaging is excluded from the Food cost input in this example.
Example result: $12.50
Frequently asked questions
Does rounding leave the target food-cost percentage unchanged?
Usually not. Holding ingredient cost fixed while changing price changes its percentage of sales. Read the recalculated percentage before choosing a price point.
What happens if Round down produces zero?
The price can be zero. If optional food cost is supplied, the form explicitly states that a percentage cannot be calculated at zero price.
