What Is an Equivalent Salary Calculator? (And How to Use One)

TL;DR: An equivalent salary calculator tells you the pay you need in a new city to keep your current lifestyle. It turns a cost-of-living index into a real dollar number you can negotiate with.

The core idea

A cost-of-living index tells you a city is "20% more expensive." An equivalent salary calculator answers the question behind it: "So what should I be paid?" It multiplies your current salary by the price difference and adjusts for tax.

How to read the result

• Equivalent salary: the pay needed to stand still.
• Monthly difference: what changes in your recurring budget.
• Largest driver: usually housing — know it before you negotiate.

When to use one

Use it before accepting a relocation offer, comparing remote-worker cities, or negotiating a raise tied to a move. It prevents the classic mistake of taking a "raise" that is really a pay cut in disguise.
