The following amounts are in Norwegian Krones (NOK), per person and includes everything except flights and insurance which I have added in the conclusion part.

Conclusion:
With flights costing 26 000kr per person and insurance costing 3000 per person, the trip ended up with a total around 80 000 krones/ 10 000 euros for 104 days. That is less than 800kr/100 euro per day including flights and absolutely everything except gifts and souveniers. That might sound like a lot, but it is less than double the amount we spend when staying at home and saving up for trip. So, in conclusion, for less than double the money you spend when working and sitting in your couch at home, you can travel the world and have thousand times the fun.
