Price development: contributions and surcharges on domestic parcel services
Rising energy and fuel prices are leading to much higher costs for Swiss Post’s logistics, especially when it comes to parcel processing. For business customers with individually agreed prices (known as "unit prices"), Swiss Post is therefore charging a variable energy surcharge on domestic parcel services since 2023.

Contribution to service costs for domestic parcel services
The parcel market is a growth market and the backbone of Swiss online retail. At the same time, it is highly competitive and both labour- and cost-intensive. The high demands on quality and infrastructure are increasing the economic pressure in the Swiss parcel market. Reasonable prices are essential to ensure that Swiss Post can continue to offer you a reliable, high-quality service in the future, develop its range of services in a targeted manner and attract and retain qualified staff in the long term. For business customers with individually agreed prices, a percentage contribution to service costs will therefore apply to domestic parcel services from 1 January 2027.

Details on the energy surcharge
The energy surcharge is variable. Swiss Post applies the energy cost index to calculate the surcharge each month. This index is based on the average prices of diesel, petrol and electricity for the previous month according to the official National Consumer Price Index (NCPI) and Swiss Post’s current energy mix for vehicle operations for parcel and letter delivery in the Logistics Services unit. This means the index calculation is transparent, traceable, and it directly reflects the development of fuel costs.
The energy cost index is updated monthly by the third working day of the month (taking data availability into consideration). The index is based on the previous month’s prices of the energy sources described above. The energy cost index determines the surcharge for all parcels to be invoiced in the respective month. Invoices are issued the following month.
The illustration below shows the method for calculating the energy surcharge.
Calculation basis
1 ↑ Electricity consumption information: the actual proportion of parcels delivered by electric vehicles stood at around 52% at the end of 2025.
