Compare 1st Class, 2nd Class, Tracked 24 and Tracked 48 for the same item.

Use the final packed weight, not the product weight, because Royal Mail prices by format and weight band.

A letter, large letter or parcel can land in a different band even at a similar weight.

Insurance, compensation upgrades and business discounts are not part of the static retail result.
1st Class is the faster standard service; 2nd Class is the lower-cost option when delivery speed is less important. The exact price depends on format and weight.
Tracked 24 is designed for delivery the next working day, but it is not an unconditional guarantee. Use the service result as a postage estimate and check Royal Mail's current terms before promising a delivery date.
It uses the published rate tables represented in the FeeStrip data. Check the linked official source and your account terms for the treatment of VAT and business-only services.
Enter the final packed weight, including the envelope, box, padding and label. A small change can move the item into the next Royal Mail weight band.
