Principle of operation of the calculator: enter character nickname, load stats, enter the number of Free stats changes, in column "new" enter future stats and you will see how much money you need, how many more stats are needed(parameter “Free stats” is negative) or how many stats would be left over(parameter “Free stats” is positive).

If you have entered the number of free changes, suggestion on the best way to spend it, would appear. This kind of inscription "??->Intelligency" in suggestion means that the number of free changes exceeds the number of stats to be chaged. At request character level and current stats could be entered manually, but with the change in the “Current” column, following parameter in “New” column would be changed to the same value automatically.
