Let's try .. On average, tickets for visiting museums of historical and other sights cost from 3 to 20 EUR, for example:

• St. Sophia Cathedral - Al Sofia - 10 EUR per person,
• Blue Mosque - 5 EUR per person,
• Dolmabahce Palace - 10 EUR per person,
• Topkapi Palace - 10 EUR per person,
• Archaeological Museum - 10 EUR per person,
• Museum of the Ancient East - 5 EUR per person

Now with regard to food . In Istanbul, a lot of restaurants, cafes and fast food . I'll tell you about the cost of food on the average in the center of the city, in the Fatih district, where all the main attractions are located and Taksim . I advise you to eat mainly in kebabs or kufte salons, as well as in locks (these are traditional Istanbul cafes) . The cost of one dinner will be on average from 2 to 8 EUR . You can go to the restaurants of their as many in the center of Istanbul, I recommend visiting for a week of your stay one time institution with a national cuisine and once with a fish . The cost of lunch will be about 20 to 60 EUR per person, with local strong drink; with import for 5-10 EUR more expensive . Note: in the snack bars are not accepted, in restaurants are accepted, but this is not always and everywhere, therefore, always specify the moment for payment .

Now mathematics)))) ) Take the approximate prices that I indicated to you, count on one person per week based on how many excursions you want to visit, then add two meals a week, add two of these amounts, you get the cost per person, and then multiply by the number of travelers human. So you will get the amount that is needed for a week.

I also highly recommend taking a small amount of about 100 EUR per person, you do not need to spend it, but it will be "NZ" for every "fireman" "The case. Or, take a bank card with you.
