Reading the result
Use this as a planning benchmark
The headline score compares six directional signals. It does not weight personal priorities, visa eligibility, household size or individual lifestyle choices.
Costs are monthly estimates, not guaranteed prices.
Higher is better for quality scores and connectivity.
Lower is better for budgets and individual expenses.
