Carina Kalkulator is a free Android application developed by VACO Software. It is a finance tool that calculates import duty and taxes for importing products in Croatia, Serbia, and Bosnia and Herzegovina. The application provides approximate values and uses the highest duty rate for some categories where duty rates differ for subcategories of the same products. The VAT is calculated based on the product price, shipping, and forwarding services that depend on the courier service.

The latest version of the application, v2.0.2, was released on 11th January 2017, and it includes the removal of ads, support activity, and developer activity. The previous version, v2.0.1, had a hotfix for interstitial ads, and v2.0 introduced two new countries, Serbia and Bosnia and Herzegovina, a currency menu, four new currencies (EUR, USD, RSD, and BAM), and four new product categories (TVs, knives, drones, and binoculars). The application is not responsible if someone is dissatisfied with the calculation, but the developer assures the users that the calculation is approximately correct.
