In many European countries, developers make between 1500 euros and 6000 euros a month. The amount per year additionally depends on how many salaries one gets (12 - 14).
So using the lowest value for salary and months, results in an amount of 18 000 euros a year.
Now one just needs to multiply this value by the amount of developers in the team and how long the software has been in development.
I am disregarding consulting rates, which tend to be higher.
Not to forget the extra costs of non-programmers in the company, taxes, office rental, water, electricity and all the other expenses business related.
