It is a tricky question. Everything depends on the complexity of your project. The more innovative technologies you want to implement, the higher the price will be. The second factor that influences the cost of data science consulting services is the geographic location of the vendor and its experience. To be more specific, an experienced data science consulting company from North America or Western Europe will set higher rates for the services they deliver than their counterparts from Eastern Eastern Europe. Still, these countries are a good choice if you want to reduce expenses. Though their rates are lower, the quality of services of Eastern European countries remains very high. If you want some specific figures, the U.S. data scientists’ salaries in the US vary from $82,300 to $236,000 per year. When it comes to the United Kingdom, the data salaries there vary from $69,000 to $119,000. Finally, in Germany, these figures will be between $75,000 and €114,000.
