To a large extent, the cost of development depends on the location of the programmer: in countries like the US or the EU, the hourly rate is much higher than in China or India due to market saturation. The leading region in terms of price/quality ratio is Eastern Europe. There, you can hire a coder for an average hourly rate of $40. Also, the cost depends on the skills and previous experience of the programmer – the more experience, the higher the hourly rate. At the same time, it is obvious that seniors earn more than middle developers.
