U got to be sure that all travel expense can be covered during your stay in the Schengen countries. Neverthless, there is no exact amount u have to pay for each country, u still should have approximately 50 GBP for everyday. Thus it depends on how many days would u stay in those countries. Some countries might be more expensive, e,g, Italy, Spain,Greece. My friend just has around 1000GBP to apply for the visa, but she got it successfully, Therefore, the most practical thing is to have an medical insurance, and the travel plan. Actually the officers in consulates only glance at your bankstatement for one min, don't worry about that. Hope u have a lovely journey then... Bonne chance...
没有一定的限制,但是钱当然是越多越好。
