Restaurant Reorder Point Calculator

Calculate when to reorder restaurant inventory from average daily usage and lead time — with optional safety stock, current levels, and suggested order quantity.

Reorder point

Formula
Basic: Reorder Point = Average Daily Usage × Lead Time
With safety stock: Reorder Point = (Average Daily Usage × Lead Time) + Safety Stock
Days Until Reorder = (Current Inventory − Reorder Point) ÷ Average Daily Usage
Suggested Order (when max set) = Maximum Inventory − Current Inventory

What it means

Multiply how much you use per day by how long suppliers take to deliver. Safety stock adds a cushion for spikes and late trucks. Optional current stock shows how many days until you should place the next order.

Good to know

  • Daily usage is relatively steady across the lead-time window.
  • Lead time is calendar days from order to receipt.
  • Basic mode sets safety stock to zero even if a value was entered earlier.

Ideal range

  • Does not optimize economic order quantity (EOQ).
  • Does not model multiple suppliers or split deliveries.

Variables

ROPReorder point
On-hand quantity that should trigger a purchase order.
Safety StockBuffer inventory
Extra units beyond lead-time demand to absorb uncertainty.
Lead Time DemandUsage during lead time
Average daily usage × lead time days.

Worked examples

Real numbers through the same formula this tool uses.

  1. 1
    Restaurant scenarioExample 1

    Basic reorder point

    20 units/day × 3-day lead time = reorder at 60 units.

  2. 2
    Restaurant scenarioExample 2

    With safety stock

    20 × 3 + 40 safety = reorder at 100 units.

  3. 3
    Restaurant scenarioExample 3

    Days until reorder

    ROP 100 with 150 on hand at 20/day → 2.5 days until the trigger; order ~50 to reach a max of 200.

How to use this calculator

Turn usage and lead time into a clear reorder trigger — then check today’s stock against it.

  1. Choose basic or safety-stock mode

    Use basic for a simple trigger. Add safety stock when demand or deliveries are unpredictable.

  2. Enter daily usage and lead time

    Use the same unit for usage and stock (cases, kg, portions).

  3. Optionally add current stock, max, and unit cost

    Current stock unlocks days until reorder. Max (or a fixed order qty) suggests how much to buy.

  4. Read the reorder point and recommended action

    Place orders when on-hand hits the trigger — not when the shelf is empty.

What is a reorder point?

A reorder point tells you when to buy — so deliveries arrive before the shelf is empty, without sitting on excess stock.

  • The trigger, not the order size

    ROP is the on-hand level that should launch a purchase order. Order quantity is a separate decision (par, case pack, or EOQ).

  • Why restaurants need reorder points

    Guesswork causes mid-service stockouts or bloated coolers. A usage × lead-time trigger keeps purchasing disciplined.

  • Reorder point vs safety stock

    Lead-time demand covers expected use while you wait. Safety stock is the cushion for surprises. ROP adds them together.

  • Restaurant purchasing best practices

    Count high-spoilage items often, keep one unit system, and review lead times when vendors change.

Best practices

Habits that keep reorder points accurate.

  • Keep units consistent

    Daily usage, safety stock, and on-hand must use the same unit — cases or kilograms, not mixed.

  • Update lead times when vendors change

    A two-day lead that becomes five days silently raises stockout risk if ROP stays fixed.

  • Set safety stock by volatility

    Produce and protein often need more cushion than dry goods or liquor.

  • Pair with days and waste tools

    Inventory Days shows coverage; Food Waste shows the cost of over-ordering past the trigger.

Common mistakes

Errors that create stockouts or excess.

  • Ordering only when the shelf is empty

    By then, lead time guarantees a gap. Reorder when you hit ROP, not zero.

  • Using purchases as daily usage

    Purchases include stock still on the shelf. Prefer true usage from counts or recipe sales.

  • Skipping safety stock on volatile items

    Weekend spikes and late trucks turn a “perfect” ROP into a stockout.

  • Never revisiting max / par levels

    Menu changes and seasonality make yesterday’s max today’s waste.
