Your Istanbul travel budget depends on your travel style. If you're a budget traveler, expect to spend $40-60 per day, covering hostels, street food, and public transport. A mid-range budget of $80-150 per day allows for a comfortable hotel, restaurants, and entry to key attractions. For luxury travel, plan for $200+ per day with five-star hotels, fine dining, and private tours. I wasn’t sure how much I’d need, but I found a great guide on Istanbul travel budget that helped me estimate my expenses. It includes price breakdowns for hotels, food, transport, and activities—definitely worth checking out before your trip!
