To be honest, in the first couple of years there will be no tangible changes in income level. When you are here you'll enjoy the quality of products, roads, environment and much more.
In the very beginning the cost of living is proportional to the increase of income. Yes, in 2-3 years you'll definitely live better, but not earlier.
If you are planning to relocate with a partner who doesn't work, the ideal option would be to live outside Amsterdam. Transportation is very good, so it'll take you the same time to get to work from Leiden or Almere as from some parts of Amsterdam, but life is cheaper there.
