Mercer’s Cost of Living calculator supplies insights for over 530 locations. Our surveys are conducted by professional researchers in each location.

Our unique international basket of goods and services reflects realistic spending habits established through years of extensive international assignees research and updated at least biannually.
The benefit of two approaches: Choose the methodology that best adapts to your unique mobility program needs and allows you to determine competitive purchasing power for all your employees, wherever they’re moving from.
Using a blended international spending pattern, this approach assumes similar spending habits among international employees from various nationalities. By comparing prices of similar brands from comparable retail outlets in both home and host cities, you gain access to data that provides a consistent and accurate assessment of living costs across locations.
This approach tailors indices and differentials to reflect the unique spending patterns of employees based on their home locations. By applying distinct weights for each country, your international employees can maintain their familiar expenditure habits in their host cities, comparing local prices from their home country with those in their new environment.
