Gauge bench
Nine calculators that run entirely in your browser. Nothing is submitted, nothing is stored, and every one of them opens with usable defaults so you can see the shape of an answer before typing anything. Where a rate or a divisor can change, it is an input rather than a hidden constant.
Two of these exist nowhere else on the sites covering this workflow: a bench that compares what a warehouse slip claims against what you measured, and a protocol that works out which entries on this desk apply to your order right now.
| # | Gauge | What it settles | Rung | Params checked |
|---|---|---|---|---|
| 01 | Landed-cost ladderoriginal | The same order costs a different amount depending on how many shipments you pay for, and almost nobody prices the three shapes before choosing one. | Rung 2 | 2026-09-11 |
| 02 | Border cost bench | Most people price an order to the penny and then discover that duty is assessed on goods plus postage, not on goods alone. | Rung 2 | 2026-09-18 |
| 03 | Parcel weight bench | A light parcel can be billed as a heavy one. Until you divide the packed volume by the line’s divisor you cannot tell which figure the quote used. | Rung 2 | 2026-09-12 |
| 04 | Slip cross-check benchoriginal | Warehouse weights and dimensions are the basis of every quote, and nobody checks them against the parcel that actually arrives. Drift that repeats is money that repeats. | Rung 2 | 2026-09-12 |
| 05 | Transit window bench | Transit estimates get quoted as single numbers. A window with 200 arrivals behind it and a window with 29 are not the same claim. | Rung 2 | 2026-09-20 |
| 06 | Line picker | Choosing a line is usually done by asking which one is fastest, which ignores that the fastest lane on a light parcel can be the worst value on a heavy one. | Rung 2 | 2026-09-20 |
| 07 | Packing and declaration bench | People ask warehouses to pack carefully, which changes nothing measurable, and forget to ask for the one thing that changes the chargeable weight. | Rung 2 | 2026-03-24 |
| 08 | Return path bench | Return decisions are made by comparing the item price against the return postage, which ignores that the handling window is closing and that a local resale may beat both. | Rung 3 | 2026-04-14 |
| 09 | Applicability protocoloriginal | A desk with dozens of entries is only useful if a reader can tell which ones apply. Reading an edge-case remedy for a low-value order wastes time and can cost money. | Rung 1 | 2026-06-12 |
Parameters carry a check date. If a quote you receive uses a different divisor or a different rounding step, change it in the gauge rather than trusting the default.
What makes these different from a spreadsheet formula
- Every gauge states its basis on the page — the divisor set, the rate band, the tolerance rule or the scoring weights. You can reproduce the output by hand.
- Where a figure is a range rather than a point, the gauge shows the range and says why it is wide, instead of collapsing it into a single confident number.
- Inputs that people get wrong are the ones that are explicit: the divisor, the rounding step, the local tax rate, the order value band.
- Nothing is hidden behind an account. There is no sign-up, no saved history and no request to a server.
The two originals, and why they were built
Landed-cost ladder
The same order costs a different amount depending on how many shipments you pay for, and almost nobody prices the three shapes before choosing one.
Three ways to move the same parcel, priced side by side.
Slip cross-check bench
Warehouse weights and dimensions are the basis of every quote, and nobody checks them against the parcel that actually arrives. Drift that repeats is money that repeats.
Compare what the slip claims against what you measured.
Applicability protocol
A desk with dozens of entries is only useful if a reader can tell which ones apply. Reading an edge-case remedy for a low-value order wastes time and can cost money.
Work out which entries apply to your order right now.
