How much does the total sum grow during customs clearance?

Loppusumma kasvaa noin 30 %

A rule of thumb is that the customs clearance adds about 30 % to the price of your purchase. 

This price includes the purchase price of the product, the transport costs as well as VAT and any customs duty. Please note that for example alcohol, alcoholic beverages, tobacco products, perfumes and eau de toilette products are always taxable.

You can also use the Customs duty calculator for the assessment.
