Convert the offer into usable income
Identify the currency, payment frequency and components included in the advertised amount. Ask how deductions are presented and distinguish fixed salary, conditional bonuses and benefits supplied by the employer. You can then estimate disposable income without directly comparing a foreign gross figure with your present take-home pay or assuming that performance-related payments will necessarily be received.
Price your life in the actual destination city
Collect costs for the neighbourhood, commute and lifestyle you are considering rather than relying on a national average alone. Include housing, utilities, food, insurance and family commitments, then test exchange-rate changes if your spending remains split between currencies. Statistical comparisons provide context; recent local quotations make the assessment more relevant to the life you would actually lead.
