For the Czech Republic it appears to be around the equivalent of 1.100 CZK per day of stay (for stays less than 30 days). For Slovenia, if you donβt have secured means of subsistence (family, paid accommodation within a tourist package, etc...), the daily means of subsistence is fixed at the equivalent of EUR 70.
You should keep in mind that being able to demonstrate the required figure is not the only aspect - proportionality of expenditure to earnings/savings is important too, as is demonstrating stable financial circumstances.
