What Does the UK Shipping Cost Comparison Calculator Do?
The calculator compares Royal Mail, Evri, DPD and another courier using the current quotes and service details you enter.
Instead of comparing postage price alone, it can also account for packaging, handling, extra courier charges, VAT treatment where relevant, delivery speed, tracking, signature requirements, compensation cover and the amount charged to the buyer for postage.
The result helps you identify the cheapest suitable service, best overall value and complete fulfilment cost before you purchase postage.
Reviewed: October 2026
SellerStack does not use a live courier-price feed for this calculator.
Courier rates, promotions, collection charges, postcode surcharges, parcel limits, delivery aims and compensation terms can change. Enter the current quote and service information shown by the courier when making an important shipping decision.
How to Use the UK Shipping Cost Comparison Calculator
Start with the parcel as it will actually be sent, not the unpackaged product. Then compare services that genuinely meet the requirements of that particular shipment.
1. Enter the Packed Parcel Details
Add the parcel weight, dimensions and item value after the item has been packaged for dispatch.
2. Select the Delivery Requirements
Choose the delivery priority and required speed, then indicate whether tracking, signature, collection or other requirements matter for the order.
3. Add Your Seller Fulfilment Costs
Include packaging and any handling amount you want reflected in the complete cost.
4. Enter Current Courier Quotes
Add the latest suitable service quote from Royal Mail, Evri, DPD and any other courier you want to compare.
5. Add Service Details
Enter delivery aim, compensation cover, extra charges and the VAT treatment shown for the quote, then mark the service features that apply.
6. Compare the Complete Result
Review total shipping cost, buyer-postage recovery, monthly cost and the suitability of each service rather than choosing from headline postage price alone.
Why This Calculator Uses Your Own Courier Quotes
Shipping prices are not permanently fixed.
The amount offered for a parcel can vary according to factors such as:
- Parcel weight
- Packaged dimensions
- Delivery speed
- Destination
- Drop-off or collection method
- Tracking or signature services
- Promotional pricing
- Business-account rates
- Additional service charges
- Postcode or location surcharges where applicable
Current quotes are more useful than an old postage table
A hard-coded courier price can become outdated quickly. SellerStack therefore lets you enter the quote available to you today and compares the services using those figures.
This also makes the calculator useful for sellers with discounted, promotional or business-account pricing.
Calculate the Complete Shipping Cost, Not Just Postage
The price shown on a postage label is not always the complete cost of sending an order.
Complete Shipping Cost
Courier Quote + Applicable VAT + Courier Extras + Packaging + Handling = Complete Shipping Cost
Some of these costs may be zero for a particular order. The purpose is to include the expenses that genuinely apply rather than automatically adding every possible cost.
Suppose a courier quote is £3.50, packaging costs £0.35 and you allocate £0.20 of handling cost.
Your complete shipping cost would be £4.05 before any other applicable courier charge.
Cheapest Courier vs Best Overall Value
The lowest-priced quote is not automatically the best shipping option.
A slightly more expensive service can be a better fit when it provides something the cheaper option does not.
Cheapest Suitable Service
Useful when the service meets all your essential requirements and your main priority is controlling fulfilment cost.
Cost Plus Suitability
Considers the balance between complete cost, delivery speed, tracking, compensation and the shipping priorities you entered.
Which suitable service gives the strongest overall result?
Saving 20p is not necessarily worthwhile if the cheaper service does not provide the protection or delivery features required for that order.
Shipping Costs UK Sellers Should Consider
Courier Quote
The current price for the delivery service you are considering.
Packaging
Boxes, mailing bags, tape, labels, protective fill and other materials used to prepare the shipment.
Handling
An optional amount representing the operational cost you want associated with preparing and dispatching the order.
Collection or Extra Charges
Add courier-specific collection fees or other charges shown for the service where they apply.
VAT Treatment
Use the VAT option according to whether the quote you entered already includes VAT or requires it to be accounted for separately.
Additional Protection
If the included compensation is not sufficient for the item, consider the cost and availability of any additional cover required.
Check Compensation Before Choosing the Cheapest Service
Item value matters because the cheapest available quote may not provide enough included compensation for the product being sent.
The calculator compares the cover entered for each courier against the value of the item so you can spot a potential shortfall before buying postage.
Compensation eligibility can depend on the item, packaging, service, evidence requirements and the courier’s current terms.
A compensation amount shown in the calculator should not be treated as confirmation that every item is covered under every circumstance.
Parcel Size and Weight Can Change the Shipping Decision
Measure the parcel after it has been packed.
A product that appears small before packaging can move into a different parcel format once protective materials and the shipping box are added.
Check Your Packed Parcel Size
Use the UK Parcel Size Checker to compare packaged dimensions and weight against common parcel-format limits before you buy postage.
Is the Postage Charged to the Buyer Covering Your Real Cost?
The amount charged to the customer for delivery and the amount it costs you to fulfil the shipment are two different figures.
Postage charged to buyer: £3.95
Complete shipping cost: £4.45
The seller is subsidising the shipment by £0.50 per order.
A £0.50 shipping shortfall across 200 orders would reduce gross profit by £100.
Review buyer postage whenever courier or packaging costs change.
What If You Offer Free Shipping?
Free delivery can be a useful pricing or conversion strategy, but the fulfilment cost has not disappeared.
It needs to be absorbed by the product margin or recovered elsewhere in your pricing.

Small Shipping Differences Can Become Large Monthly Costs
A difference of a few pence may look insignificant when evaluating one parcel.
At higher order volume, the same difference can become meaningful.
| Saving per Parcel | Monthly Parcels | Potential Monthly Saving |
|---|---|---|
| £0.20 | 100 | £20 |
| £0.40 | 250 | £100 |
| £0.75 | 500 | £375 |
| £1.00 | 1,000 | £1,000 |
Enter a realistic monthly parcel volume when comparing services. This turns a small per-shipment difference into a clearer business decision.
Understanding the SellerStack Shipping Verdict
The calculator does not simply rank every courier from cheapest to most expensive.
It compares the services against the shipping requirements entered and can highlight different strengths.
Best Overall Value
The strongest balance of cost and the delivery requirements entered for the shipment.
Lowest Cost
The cheapest complete shipping cost among suitable services in the comparison.
Fastest Option
Highlights the quickest suitable service based on the delivery aims entered.
Best Protection
Helps identify the service offering the strongest entered protection for the value and requirements of the parcel.
A service can look attractive on price while missing a requirement such as tracking, signature, speed or sufficient compensation.
Review any suitability warning before purchasing the shipping label.
Royal Mail vs Evri vs DPD: Which Courier Should You Use?
There is no permanent winner for every shipment.
The best option can change with the parcel, current quote and delivery requirements.
| Factor | What to Compare |
|---|---|
| Price | Current quote plus the extra costs that actually apply. |
| Delivery | Whether the stated delivery aim suits the order. |
| Tracking | Whether tracking is included when you require it. |
| Signature | Whether signature confirmation is available or needed. |
| Compensation | Whether the item value is adequately covered under the current service terms. |
| Handover | Whether collection, drop-off or another handover method fits your operation. |
Avoid assuming Royal Mail, Evri, DPD or another courier will always be cheapest, fastest or best protected.
Compare the actual services available for the parcel you are sending.
Worked Example: Comparing Three UK Courier Quotes
The figures below are deliberately illustrative rather than advertised courier rates.
Parcel Details
- Weight: 1 kg
- Dimensions: 30 × 20 × 10 cm
- Item value: £30
- Tracking required
- Standard delivery speed
- No signature required
Seller Costs
- Packaging: £0.35
- Handling: £0.20
- Buyer postage charged: £4.00
Example Courier Quotes
| Courier | Illustrative Quote | Example Delivery Aim |
|---|---|---|
| Royal Mail | £3.60 | 2 working days |
| Evri | £3.45 | 2–3 working days |
| DPD | £4.25 | Next working day |
If all three services meet the essential requirements, Evri has the lowest example quote.
But if speed is the seller’s highest priority, the higher-priced DPD example may produce the stronger overall result.
The calculator is designed to make that distinction visible rather than assuming the lowest quote must always win.
The courier prices in this example are sample figures used to demonstrate the calculation.

Practical Ways to Control Shipping Costs
1. Measure After Packing
Use the final packaged weight and dimensions rather than the product measurements alone.
2. Compare Suitable Services Regularly
Prices and promotions change, so do not assume the service that was best last month is still best today.
3. Track Packaging Cost
Even inexpensive mailing materials become meaningful when multiplied across hundreds of orders.
4. Review Buyer Postage Charges
Make sure the amount charged for delivery still reflects your current complete fulfilment cost.
5. Match Protection to Item Value
Higher-value orders may justify a different service from inexpensive, easily replaceable products.
6. Review the Monthly Effect
Judge small per-order differences against your actual shipping volume before dismissing them as insignificant.
Shipping Supplies for Regular Online Sellers
Keep suitable mailing bags, cardboard boxes, packing tape and protective materials on hand so parcels can be packed securely without adding unnecessary size or fulfilment cost.
Common Shipping Cost Comparison Mistakes
1. Comparing Postage Price Only
Packaging, handling and courier extras can change which service is cheapest overall.
2. Choosing the Cheapest Service Automatically
A cheaper option can be unsuitable if it misses an important delivery, tracking or protection requirement.
3. Measuring the Product Instead of the Packed Parcel
Packaging can increase both dimensions and weight.
4. Forgetting Packaging Cost
Boxes, mailing bags, tape and protective materials belong in the complete fulfilment cost.
5. Ignoring Buyer-Postage Shortfalls
Under-recovering shipping by a small amount on every order can materially reduce monthly profit.
6. Using Old Courier Prices
Recheck quotes rather than relying permanently on an old label, spreadsheet or screenshot.
7. Ignoring Compensation Limits
The cheapest service may not provide suitable protection for a higher-value item.
8. Forgetting Extra Courier Charges
Collection and other additional charges should be included when they apply to the service.

What does the UK Shipping Cost Comparison Calculator compare?
It compares Royal Mail, Evri, DPD and an additional courier using the quotes and service details you enter. It can consider complete fulfilment cost, delivery speed, tracking, signature, compensation cover and your selected shipping priorities.
Does SellerStack show live courier prices?
No. You enter the current quote available to you. This avoids relying on fixed courier prices that may become outdated or may not reflect your parcel, account or current promotion.
Which UK courier is cheapest?
There is no permanent cheapest courier for every shipment. Price can vary with parcel size, weight, destination, service, handover method, account pricing and current promotions.
Should I always choose the cheapest courier?
No. The cheapest suitable service may be a good choice, but a slightly more expensive option can offer better value when you require faster delivery, tracking, signature or stronger compensation.
Does the calculator include packaging costs?
Yes. Enter packaging separately so boxes, mailing bags, tape, labels and other materials can be included in the complete shipping cost.
Can I include handling costs?
Yes. The calculator provides a handling-cost field if you want to include an operational cost for preparing and dispatching the order.
Why does the calculator ask how much postage the buyer paid?
This lets the calculator compare buyer-paid postage with your complete shipping cost and show whether you are recovering the expense, creating a surplus or subsidising delivery.
Can I compare a courier other than Royal Mail, Evri or DPD?
Yes. The calculator includes an additional courier option where you can enter another service and its current quote.
Does the calculator include VAT?
You can specify the VAT treatment of each courier quote so the comparison can reflect whether VAT is already included or needs to be considered separately.
Why does item value matter?
Item value helps you compare the compensation entered for each service against the value of the parcel and identify a potential protection shortfall.
Can the calculator compare monthly shipping costs?
Yes. Enter your approximate monthly parcel volume and the calculator can show how the per-order shipping cost scales across your expected volume.
Can I use the calculator for eBay, Amazon, Etsy or Shopify orders?
Yes. The calculator is marketplace-independent and can be used for parcels from marketplaces or your own online store, provided you enter the relevant shipping information.
Are SellerStack shipping calculator results exact?
No. Results are planning estimates based on the information you enter. Final courier price, eligibility, delivery terms, compensation and parcel acceptance remain subject to the courier’s current rules.
Is the UK Shipping Cost Comparison Calculator free?
Yes. The calculator and SellerStack’s other reseller tools are free to use.
Compare the Complete Fulfilment Cost, Not Just the Label Price
Shipping decisions affect both profit and the customer experience.
The cheapest headline quote can stop being the cheapest once packaging, handling and extra charges are included, while the lowest-cost service may not meet the delivery or protection needs of every order.
Enter current quotes, compare suitable services and judge the result using the complete cost before purchasing postage.
Use the Calculator as a Shipping Planning Tool
The SellerStack UK Shipping Cost Comparison Calculator is provided for general planning and comparison purposes.
It does not provide a live courier-price feed. Results depend on the quote, parcel information, costs and service details you enter.
Courier rates, parcel limits, delivery aims, compensation terms, prohibited and restricted items, collection charges, postcode surcharges and service availability can change.
Before purchasing postage, confirm the final price, parcel eligibility and current terms directly with the courier.
