I seem to remember that toll.no have their own import calculator too. I have been using it a few times when I was living in Norway. Overall, I remember that the fees were quite significant, probably manageable with the median salary in Norway, but tougher for someone with only a French salary. Anyway, the amounts depending on product types are all well explained on the website. Also, multiple times, I noticed that web stores did not offer to buy at the price excl. the EU VAT when shipping to Norway, which is wrong. And the Norwegian fees were added on top of that. I had to contact the web stores after delivery to ask for a partial refund, which they sometimes agreed to do, but was still losing a bit because the Norwegian fees I paid were calculated on the full price including VAT.
