How to Calculate PAR Levels for Your Restaurant

Restaurant PAR levels are the foundation of smart inventory management. PAR — Periodic Automatic Replenishment — tells you the minimum quantity of each ingredient you need on hand at all times to get through your ordering cycle without running out.

Most restaurants over-order because they don't have PAR levels set. The result: cash tied up in inventory, ingredients that expire before you use them, and a walk-in that looks full but is actually costing you money every day.

What Is a PAR Level?

PAR stands for Periodic Automatic Replenishment. Your PAR level is the minimum quantity of each ingredient you need before you reorder.

Think of it as a trigger point:

• If on-hand quantity drops at or below the PAR level → reorder
• If on-hand quantity is above the PAR level → don't order

The PAR level is not how much you want to have. It's the minimum you need to avoid running out.

The PAR Level Formula

PAR Level = (Average Daily Usage × Lead Time) + Safety Stock

Where:

• Average Daily Usage = how much of the ingredient you use per day on average
• Lead Time = days between placing an order and receiving it (usually 1–3 days)
• Safety Stock = buffer for unexpected demand (typically 20–25% of average usage during lead time)

Example:

• You use 10 lbs of chicken breast per day on average
• Supplier delivers every 2 days (lead time = 2)
• Safety stock = 4 lbs (20% buffer)
• PAR Level = (10 × 2) + 4 = 24 lbs

When chicken breast drops to 24 lbs, you order more. Not before, not after.

How to Calculate Average Daily Usage

Pull your POS data and invoices for the last 4 weeks. For each ingredient:

1. Total quantity used over 4 weeks
2. Divide by 28 days
3. That's your average daily usage

Also calculate by day of week — your usage on Friday is probably 2–3× your Monday usage.

Practical PAR Level Table for Common Items

Item	Avg Daily Use	Lead Time	Safety Stock	PAR Level
Chicken breast	10 lbs	2 days	4 lbs	24 lbs
80/20 ground beef	8 lbs	2 days	3 lbs	19 lbs
Roma tomatoes	15 lbs	2 days	6 lbs	36 lbs
Heavy cream	2 qts	3 days	1 qt	7 qts
Olive oil	1 liter	7 days	2 liters	9 liters
AP flour (baking)	5 lbs	7 days	5 lbs	40 lbs

Maximum PAR: Avoiding Over-Ordering

Your maximum PAR prevents over-ordering:

Max PAR = Average Usage During Order Cycle + Safety Stock

If you order chicken twice a week and use an average of 70 lbs per week, you need about 35 lbs per order cycle plus safety stock. Max PAR ≈ 40–42 lbs. Ordering more ties up cash and risks spoilage.

How to Use PAR Levels in Daily Ordering

Build a daily inventory count sheet listing every key ingredient and its PAR level. Before placing orders:

1. Count on-hand quantities
2. Compare to PAR levels
3. Order enough to reach your maximum PAR for each item at or below minimum PAR

This takes 15–20 minutes per day and eliminates the "what do we need?" guessing that leads to both over-ordering and running out of critical items.

Frequently Asked Questions

How often should I update my PAR levels?

Review PAR levels quarterly, or whenever your sales volume or menu changes significantly. Seasonal menus, increased covers, or adding/removing dishes all affect your average daily usage.

What's the difference between PAR level and reorder point?

They're the same concept. "Reorder point" is the inventory management term; "PAR level" is the restaurant industry term. Both mean the quantity at which you trigger a reorder.

Should I set PAR levels for every ingredient?

Start with your top-cost and highest-usage ingredients — proteins, produce, dairy. A restaurant typically tracks PAR for 30–60 items; not every single dry good needs a formal PAR.

Can my POS or inventory software set PAR levels automatically?

Yes. Most inventory management platforms (MarketMan, BlueCart, Craftable, CostLab) let you set PAR levels per item and will alert you when items fall below PAR during a count.
