Every restaurant using real tableware loses pieces to breakage. The question worth answering before it happens is how much, and on which items, so replacement ordering doesn’t turn into a surprise. There isn’t a single industry-wide number, but there are reasonable ranges and a method for finding yours.

What breaks first, in our experience

Rim-edge plates and shallow, wide bowls take the most damage in a typical kitchen, since they’re handled constantly and their exposed edges chip easily against other dishware in a sink or bus tray. Deep, narrow pieces like a chawan or a tall yunomi tend to survive longer simply because there’s less exposed edge to catch on something.

Material changes the rate substantially

Porcelain and stoneware used in normal table service typically see lower breakage than lacquerware or anything handled in a high-volume dish pit, and they tend to have a fairly predictable, steady attrition rate once a kitchen settles into its routine. Glassware, where used, almost always breaks faster than ceramics.

Lacquerware is the outlier. If it’s being used outside its recommended care, run through a dishwasher despite instructions, for instance, it can have a much higher and far less predictable loss rate. That’s one more reason to be deliberate about which pieces are lacquerware versus ceramic in the first place.

Service style changes the math too

A sit-down restaurant with table service generally sees less breakage than a high-turnover or buffet-style setup, where pieces get stacked, carried, and washed more frequently and more roughly. Two kitchens using identical tableware can have very different attrition rates purely because of how the room runs.

A simple way to measure your own rate

Rather than guessing, track breakage for one month against your total piece count for your highest-use items, usually your core plate and bowl shapes. If you lose, for example, 5 out of 100 plates in a month, that’s roughly a 5% monthly attrition rate on that item, which you can use to estimate a quarterly reorder quantity, roughly 15% of your stock count, before you actually run short.

For a new account without historical data, plan a modest replacement budget on core items, rice bowls and everyday plates especially, since these see the most daily handling. It’s better to slightly overestimate in year one and adjust down once real data exists. Once a kitchen has six months of reordering behind it, the real breakage rate usually becomes obvious without needing an industry benchmark at all.

Why this matters more than it seems

Running short on a core plate or bowl mid-service is a bigger problem than it sounds, since it can force a kitchen to substitute a mismatched piece for a dish, undercutting exactly the presentation effort that piece was chosen for in the first place. Tracking even roughly avoids that scramble.

A practical ordering rhythm

Once you have a rough attrition rate, a quarterly top-up order for your core shapes, sized to that rate, tends to work better than waiting until stock visibly runs low. It also smooths your spending into smaller, predictable orders rather than large, reactive ones.

What this looks like against our minimum

For most restaurants running a moderate volume of core plates and bowls, a quarterly top-up order lands comfortably above our minimum order threshold on its own, which makes this rhythm easy to fold into a regular ordering schedule rather than treating replacement stock as a separate, occasional purchase.

A couple of related questions

Should I just order extra of everything upfront to avoid this entirely? We’d generally advise against it. Overstocking ties up money in inventory that may not match next season’s needs, where a quarterly rhythm based on actual attrition keeps you closer to what you’ll really use.

Does this apply to retail shelf stock the same way it applies to restaurant use? Less directly. Retail breakage is usually lower since pieces aren’t handled as constantly, but the quarterly review habit is still a reasonable one to apply to slow-moving versus fast-moving SKUs.
