Estimate shipping from a real quote
A shipping estimate is only as good as the fields behind it. The destination, the service level, the billing basis and the surcharges decide the number — and each of them can change after you have written it down.
Six fields in every quote
Whenever a carrier page, a platform checkout or a written message gives you a shipping figure, copy these six things before you do anything else with the number:
- Destination. Country, and the postcode area if the quote is postcode-dependent. A quote for "the UK" is not a quote for your address.
- Service level. Economy, tracked, express, signed-for. The same parcel at the same weight can carry three different prices.
- Billing basis. Actual weight, volumetric weight, or a flat rate per parcel or per item.
- Surcharges. Remote-area fees, fuel surcharges, oversized-item fees, signature fees. Note whether each is included or added later.
- What is excluded. Import duties, VAT, customs handling. These are frequently outside the quoted figure and are the most common reason a budget goes wrong.
- Quote date and source. The date you read it, and a link or a saved screenshot so the figure can be re-checked.
The billing basis decides everything
A quote is an instruction about which weight the carrier will charge for. If you recorded "£18.00 for 2 kg" without noting whether that was actual or volumetric weight, you cannot tell whether your parcel qualifies. A bulky coat in a large box can bill far above its physical weight; a dense pair of boots can bill exactly at it.
Record the basis as a word, not an inference. When the quote page does not state it, write "basis not stated" and treat the figure as provisional. The mechanics are set out in comparing actual and volumetric weight.
A quote record template
One row per quote, even for quotes you reject — a rejected quote is evidence about how the price behaves. Figures below are invented for illustration.
| Field | Quote A | Quote B |
|---|---|---|
| Destination | United Kingdom, example postcode | United Kingdom, example postcode |
| Service | Tracked economy | Tracked express |
| Billing basis | Actual weight, 1.8 kg | Volumetric, 3.2 kg |
| Base charge | £18.00 | £29.50 |
| Surcharges | None stated | £3.00 signature |
| Excludes | Duties and VAT | Duties and VAT |
| Quote date | 20 Oct 2026 | 20 Oct 2026 |
Why the figure moves
Quotes are conditional. Change the parcel dimensions and a volumetric calculation changes. Add an item and you may cross a weight band. Choose a signature service and a fee appears. Carrier rate tables are also revised, which is why the quote date is not decoration.
Two habits keep the record honest. First, re-quote whenever the basket changes materially rather than adjusting the old number by feel. Second, keep the superseded figure in a dated column so you can see how much the estimate drifted. If you find yourself re-quoting weekly, the packing choices may be the actual problem, because reducing packed volume can change the billing basis entirely.
Transit time, read honestly
Separate three different claims, because sellers often blend them: the time to dispatch from a warehouse, the transit time with the carrier, and the estimated delivery date at your address. Only the third is a date you can plan around, and even then it is an estimate unless the seller states a guarantee.
Record working days rather than calendar days when that is what the carrier publishes, and note public holidays separately — a bank holiday in the destination country does not appear in a generic "3–5 working days" line. Add a column for "expected arrival window, if stated" and leave it blank when the seller gives none.
Check restricted categories before you rely on any quote — perfume, liquids and items with batteries all need carrier confirmation. Start with checking transport restrictions, then put the final figure into the budget tool on the hipobuy spreadsheet home page.
