How to Calculate Inventory Par Levels for Your Restaurant

Restaurant par levels are a critical component of effective inventory management and cost control. Maintaining accurate and effective par levels is a balancing act. Operators must maintain adequate inventory levels to meet customer demand, including a little extra in case they get surprised with large orders, and yet keep supplies low enough that they’re not running up against expiration dates and must throw out food or tie up too much cash in unused inventory. Inventory management is one of the biggest challenges of restaurant management. 

Why Inventory Par Levels Are Important

Accurate and regular inventory counts are key to maintaining effective restaurant par levels as this will ensure an operation always has the stock they need, when they need it. Determining appropriate par levels requires a little bit of work, but the payoff and benefits are worth it.

How to Calculate Restaurant Par Levels

Calculating restaurant par levels requires several pieces of data:

  • Inventory turnover rates for each item.
  • Delivery schedules for each item.
  • Customer demand for each item.
  • Average inventory on hand for each item.

Inventory Par Level Calculation

Wondering how to calculate par levels? Inventory par levels can be calculated using this formula:

Weekly Inventory Use + Safety Stock/Deliveries Per Week = Recommended Par Level

As an example: 

  • 15 cases of chicken are used each week.
  • 3 cases (20%) are kept on hand as safety stock.
  • You receive 2 deliveries each week.

Using the formula, 15+3 = 18. Divide 18 by 2 deliveries to arrive at 9. The restaurant par level for chicken is 9 cases.

Remember that your par level may change over time based on seasonal demand or other factors, which is why it is so important to be doing regular inventory counts and following your sales and turnover rates every week. Armed with regular inventory par level calculation data, you’ll be able to make adjustments as soon as you notice sales are deviating from the norm, ensuring your stock is aligned with demand.
