1. Start with take-home pay, not the sticker salary
Base pay headlines almost every job offer, yet it says nothing about the money you will actually keep. Run the role’s headline salary through the relevant city calculator to quantify income tax, social contributions, and local deductions. Convert to monthly or biweekly numbers so you can track real spending power. If the role offers variable compensation (bonus, RSUs, overtime), model best- and worst-case scenarios to establish your negotiation guardrails.
Compare the resulting net pay with your current destination or alternative offers. Focus on what changes in your pocket after tax, not just what is added before it. International candidates often discover that a 10 % headline increase in Country A can result in lower take-home pay than staying in Country B once social insurance or pension contributions are applied.
