Cost of Living - Salary Negotiation

Hello,

My fiance and I are looking into moving to Norway. There are many reasons why we are wanting to live in your beautiful country, but I will not get into those here.

TLDR; What would a good salary be for an average or "middle class" lifestyle in Norway? What would be a good Salary to negotiate for in a technical engineering field?

My main question is regarding my job search. I am trying to determine what a comfortable salary would be to help in interviews and negotiations. I currently am employed in the USA working in aerospace as an engineer at an aircraft manufacturer. My field is human engineering with a focus on training and safety. I have a bachelor's of science with 6 years of experience. With all of the state benefits, tax system, and other social systems I understand it is not a simple conversion. I have tried to put conversions below into Norwegian currency and give some description of our lifestyle. I understand salaries in Europe are lower than the USA but there are benefits that offset the lower salary. I would say my girlfriend and I live a middle class (average but able to save for emergencies and retirement, while being able to take 2-3 vacations per year) lifestyle in the US. More financial details below.

Yearly salary: 1,257,989 krone (119,000 USD).

I currently make 614 krone per hour (58 USD) and monthly take home is 97,000 krone ( 9,200 USD) before taxes. I save 10,600 krone (1,000 USD) each month for retirement. I pay 23,000 krone (2,200 USD) each month in taxes. My health insurance provided through my employer costs 317 krone (30 USD) per month, my annual deductible 35,000 krone (3,300 USD) and my max out of pocket per year is 66,000 krone (6,200 USD). We currently rent a 140 sq. meter apartment (1500 ft.) and pay 18,000 krone (1,700 USD) in rent and utilities. We both drive Mazdas 300,000 krone (30,000 USD). We try to eat healthy and buy fresh ingredients so our food budget is 7,400 krone (700 USD) per month. We go out to eat a couple times a week and spend 12,500 krone (1,200 USD) a month at restaurants. We don't spend much money on activities as we enjoy biking and hiking and being outside which is usually cheap or free. We do enjoy the arts and festivals and spend 4,200 kroner (400 USD) a month on event tickets like concerts and cultural festivals. The rest goes into savings for emergencies and vacations and household items.
