Warehouse KPIs: The 10 Metrics Every Supervisor Should Track Monthly

The 10 warehouse KPIs every supervisor should track each month are order accuracy, on-time shipping, inventory accuracy, inventory turnover, pick rate, labor cost per unit, order cycle time, dock-to-stock time, shrinkage rate, and fill rate. Together they tell you whether orders go out right and on time, whether your stock numbers can be trusted, and whether your labor is getting more or less efficient. You can track all ten in one spreadsheet you update once a week, no warehouse software required.

What are warehouse KPIs (and how many should you track)

A warehouse KPI (key performance indicator) is a single number that shows whether part of your operation is healthy or slipping. The trap is tracking forty of them and acting on none. Keep your monthly scorecard to five to ten that map to what you actually get measured on: accuracy, speed, and cost.

We spent 20-plus years on the warehouse floor pulling these exact numbers for the monthly review. The ten below are the ones that consistently moved the needle, with the benchmarks worth aiming for. Targets shift by industry, so treat them as starting points and compare against your own trend month over month.

Warehouse KPI benchmarks at a glance

Here is the quick-reference scorecard. Benchmarks vary by industry and product type, so use them as starting targets.

KPI	How to calculate it	Benchmark to aim for
Order accuracy rate	Error-free orders / total orders	99% or higher
On-time shipping rate	Orders shipped on time / total orders	98% or higher
Inventory accuracy	Counted units matching system / units counted	97% or higher
Inventory turnover	Cost of goods sold / average inventory value	4 to 6 turns a year (varies)
Pick rate	Units picked / labor hours	Trend up vs your baseline
Labor cost per unit	Total labor cost / units shipped	Trend down vs your baseline
Order cycle time	Time from order received to shipped	Shorter is better
Dock-to-stock time	Time from receiving to put away and sellable	Under 24 hours
Shrinkage rate	Value of lost stock / total inventory value	Under 1% to 2%
Fill rate	Order lines shipped complete / total order lines	98% or higher

1. Order accuracy rate

Order accuracy is the share of orders that ship with the right items, quantities, and address, calculated as error-free orders divided by total orders. Aim for 99% or higher. It is the KPI customers feel first: every wrong order means a return, a refund, and a dent in trust. Track the reason codes behind errors (wrong pick, wrong count, wrong label) so you fix the cause, not just the symptom.

2. On-time shipping rate

On-time shipping is the percentage of orders that leave by their promised cutoff: orders shipped on time divided by total orders, with 98% or higher a strong target. A slipping number here usually points upstream to picking delays or a receiving backlog, so read it alongside cycle time and dock-to-stock.

3. Inventory accuracy

Inventory accuracy measures how well your system count matches the shelf, found by dividing the units that match by the units counted during a cycle count. Aim for 97% or higher. When this number is low, every downstream promise is built on sand: you oversell, you scramble, and you lose orders you thought you could fill. Cycle counting a slice of locations each week keeps it honest without a full annual shutdown.

4. Inventory turnover

Inventory turnover shows how many times you sell and replace your average stock in a year: cost of goods sold divided by average inventory value. For many operations 4 to 6 turns is healthy, though grocery and fast-moving goods run far higher and slow, seasonal items run lower. Too low ties up cash in stock that sits; too high risks stockouts. Read it against your own history and your industry, not a single universal number.

5. Pick rate (units per labor hour)

Pick rate is your core productivity number: units picked divided by labor hours. There is no universal target, so the move is to set your baseline and watch the trend. A rising pick rate means your layout, slotting, and process are working. A falling one is an early warning before it shows up in late shipments.

6. Labor cost per unit

Labor is usually the biggest controllable cost in the building, so track labor cost per unit: total labor cost divided by units shipped. The goal is a flat or falling number as volume grows. If it creeps up while volume is steady, you are paying for overtime, rework, or idle time, and that is your cue to look at scheduling and pick paths.

7. Order cycle time

Order cycle time is the clock from the moment an order lands to the moment it ships. Shorter is better, and the trend matters more than the absolute number. Watching it monthly catches creeping delays while they are still a process tweak and not a customer complaint.

8. Dock-to-stock time

Dock-to-stock measures how long it takes received goods to be put away and sellable. Aim for under 24 hours. Stock stuck on the receiving dock is invisible to your system, so it cannot be picked or sold, which quietly drags down both fill rate and on-time shipping.

9. Shrinkage rate

Shrinkage is inventory lost to theft, damage, or error, calculated as the value of lost stock divided by total inventory value. Keep it under 1% to 2%. It rarely announces itself, so the only way to manage it is to measure it. A rising rate is a signal to look at receiving checks, security, and how damage is logged.

10. Fill rate

Fill rate is the share of order lines you ship complete the first time: lines shipped complete divided by total lines, with 98% or higher a strong target. A low fill rate sends customers elsewhere and often traces straight back to inventory accuracy and dock-to-stock. Track it monthly and it becomes an early read on the whole flow.

Frequently asked questions

What is the most important warehouse KPI?

Order accuracy is the most important warehouse KPI for most operations, because it is what the customer feels first and it drives returns, refunds, and trust. Aim for 99% or higher. If you only watch a handful of numbers, pair order accuracy with on-time shipping and inventory accuracy.

What is a good inventory accuracy percentage?

A good inventory accuracy rate is 97% or higher, measured by how often a cycle count matches your system. Below that, you start overselling and missing orders you thought you could fill. Regular cycle counting, counting a slice of locations each week, is the most reliable way to hold accuracy high without a full shutdown.

How many KPIs should a warehouse track?

Track five to ten warehouse KPIs, not forty. A scorecard nobody updates is worse than none. Start with accuracy, on-time shipping, and labor cost per unit, then add the rest as the habit sticks. The goal is a number you review every month and act on.

Can I track warehouse KPIs without a WMS?

Yes. Every KPI here can be tracked in a spreadsheet by entering your daily counts and letting formulas calculate the rates and trends. A done-for-you template in Google Sheets or Excel gives you the structure of a warehouse management system report without the software cost, which is why many small and mid-size operations start there.
