How to Use Cost of Living Data in Salary Negotiations
Using cost of living data in negotiations means framing your request in terms of real purchasing power rather than raw numbers. If your city's rents rose 15%, you need at least a 15% nominal raise just to stand still.

Know your income percentile first
Before negotiating, know where your current salary sits nationally. Use the Cushy Index income percentile calculator. If you are below the median, you have a strong anchor point.
Frame around net and purchasing power
A 5% gross raise in Spain at €60,000 adds roughly €1,800 net — €150/month. Frame this against documented rent increases in your city.

How much should I ask for in a salary negotiation?
A reasonable benchmark: CPI inflation plus documented increases in local housing costs, plus a performance premium if applicable. Anchoring to your income percentile position strengthens the case.
