Here’s a scenario we hear a lot: you glance at the shelf, notice you’re down to your last few bags, and place an order. Sometimes that works out fine. Other times you’re paying rush freight, or you’ve got pallets stacked in a hallway because you ordered more than you had room for.
Guessing by eyeballing what’s left isn’t really a strategy — it’s a habit that happens to work until it doesn’t. The good news is you don’t need fancy inventory software to fix this. You just need a handful of numbers you probably already have.
Start with what you actually use in a normal week
First, figure out your real weekly usage — not a guess, an actual number. How you track it depends on what you do with the salt.
Running a float spa? Log the pounds that go into tank setup, top-offs, and full water changes. Making bath products? Look at how much goes into a batch. Running a barn or equine facility?
Count the bags you open week to week.
Don’t just grab one week and call it done — a single week might be unusually slow or unusually busy, and either one will throw off your number. Pull data from at least four weeks, add it up, and divide by the number of weeks. Used 800 pounds over four weeks? That’s 200 pounds a week, on average.
Now factor in the seasons and the growth you’re planning for
That weekly average is a solid starting point, but it’s not the full picture. Demand doesn’t stay flat all year.
Wellness brands often see a bump heading into the holidays. Float centers tend to get busy right after New Year’s, when everyone’s making resolutions. A manufacturer picking up new wholesale accounts can see production climb fast, sometimes faster than expected.
Look back at last year’s sales, bookings, or production runs. If a particular season historically brings a 20% jump, build that into your estimate now, before you place the order — not after you’ve already sold out. And don’t forget the changes that don’t show up in last year’s numbers at all: a new location, a bigger production run, a marketing push, a new service on the menu.
Any of those can make your historical pattern irrelevant.
Keep a buffer, but keep it practical
No forecast is going to catch every late shipment or every unexpected surge in orders. That’s what a buffer is for — it’s the extra supply sitting on the shelf that keeps you covered when reality doesn’t match the plan.
How much buffer you need really comes down to three things: how much room you have to store it, how much cash you can tie up in inventory sitting on a shelf, and how long your supplier takes to deliver. A week’s worth of extra stock is plenty for some businesses. Others need two weeks or more, especially if running out means stopping production or turning away clients.
The point isn’t to cram every corner of your storage space full of bags. It’s to have just enough cushion that one bad week doesn’t turn into an emergency.
Turn all of that into an actual order number
Once you’ve got your weekly average, your seasonal bump, and your buffer, the math is simple:
Weekly usage × weeks until your next order, plus your buffer = how much to order
Say you use 200 pounds a week and you’re ordering enough to last eight weeks. That’s 1,600 pounds. Add a 400-pound buffer, and you’re ordering 2,000 pounds.
From there, translate that number into whatever units your supplier sells — bags, totes, pallets — and take a second to check your receiving area. Can it handle the delivery? Do you have clean, dry space ready for it before it shows up?
Check your work after every order
Your first estimate won’t be perfect, and that’s fine. What matters is that it gets sharper every cycle.
After each order arrives and gets used, look back: how much was left over, did demand shift from what you expected, did the shipment show up on time? A few small corrections after each cycle, and you’ll land on an ordering rhythm that actually fits how your business runs.
