The red-figure audit, one destination at a time
Pick a destination, pick a line, and see which fee bands the estimator’s red price shrinks and what JoyaGoo’s coupon wording says about each of them.
Run the audit on one line
UK-RoyalMail-P · United Kingdom · struck $23.29, red $17.47
On UK-RoyalMail-P to the United Kingdom, about 17.9% of the saving the red figure assumes (about $1.05 of the $5.82 shown as Coupon:Save) falls on fees that the coupon wording leaves out or never names.
How to use the audit tool
Choose a destination from the list. The panel fills with every line JoyaGoo’s estimator returned for that country for a 1,000 g parcel of 30 by 20 by 10 cm, in the order the estimator listed them. Each button shows the red figure, the struck total, the Coupon:Save amount and any Free Insurance or Tax Free tag the line carried.
Click a line. The bar below is the struck total split into its fee bands, and the pale end of each band is the 25% the red figure takes off it. The table gives each band in dollars, the quarter assumed off it, and what the coupon wording says about that kind of charge.
The sentence at the bottom is the point of the exercise: how much of the card’s Coupon:Save amount sits on charges the coupon wording either excludes or never mentions. Switching destination resets the panel to the first line in that country’s list.
What each colour in the bar stands for
Blue is freight, the weight-based charge, and the only band JoyaGoo’s coupon card names: its usage label reads Freight.
Brick red with stripes is the customs and declaration fee of $8.04 per parcel. It appears on 13 of the 28 line names, among them EUB, eEms, EMS-60, CD-AIR, PostNL-Z-T and the DHL air lines, and it is the one charge the default coupon line rules out in words (“does not include customs clearance”).
Amber is the operation fee of $2.51; the estimator’s Detail panel labels it Service Fee. Pale amber is a second fee of $1.67 that the public data calls serviceFee and that has no row in the Detail panel at all; EUB lines do not charge it. Grey is an air surcharge, which only XJ Australia Line-Bags carried in our snapshot. None of these three is named in any coupon wording we found.
The arithmetic behind the closing sentence
The tool adds up every band except freight, divides by the struck total and shows the result as a percentage. Because the red figure takes the same quarter off every band, that percentage is also the share of the Coupon:Save amount that sits outside freight.
The dollar figure next to it is a quarter of those non-freight bands, rounded half up to the cent. It can differ by a cent from what you would get by subtracting, because JoyaGoo rounds the red figure and the Coupon:Save amount separately: EUB to Australia shows $20.60 red and Coupon:Save $6.87, which add up to $27.47, one cent above the struck $27.46.
The tool repeats JoyaGoo’s numbers; it does not recompute them from weights. Weight steps and chargeable weight are outside this audit.
What the audit deliberately leaves out
No coupon values. The tool never estimates what a real JoyaGoo coupon would save on a line, because coupons in the account carry their own minimum spend, maximum discount and expiry that we cannot see.
No combining. Whether a VIP coupon, a shipping discount and a code can be used together is JoyaGoo’s rule to state, and its help pages say different things.
No final bill, and no ranking. The tool does not tell you what you will pay or which line is best. Lines differ in speed, insurance, restrictions and handling of failed deliveries, and the red figure says nothing about any of those. For those, read the estimator’s own cards and line notes, and confirm on the checkout page.
Destinations and lines in this snapshot
The snapshot covers 15 destinations: the United States, United Kingdom, Canada, Australia, Germany, France, the Netherlands, Poland, Spain, Ireland, Italy, New Zealand, Sweden, Belgium and Switzerland. At 1,000 g they returned 99 destination-line pairs between them, built from 28 different line names.
The same line name can carry a different struck total in each country. PostNL-Z-T, for example, came out at $42.26 for Germany and $77.52 for Australia on the same parcel. The tool keeps every pair separate.

Checking the numbers yourself
Open the JoyaGoo estimator, choose a destination, enter 1000 in the weight box and 30, 20 and 10 for the sides, then press Calculate. Each line shows the red figure, the struck total and the Coupon:Save label. Click Detail on a line to see the Charge Standard panel with first and continued weight prices, the customs and declaration fee and the fee labelled Service Fee.
If your numbers differ, first compare the input weight, dimensions, currency, selected line and quote date; pricing may also have changed since 17 October 2026; its estimator notes that third-party lines adjust freight with the market. Tell us at [email protected] and we will re-run the snapshot.
