There is no single answer to the question of how much money to bring to Georgia. For a student, one amount will be sufficient, while a family vacation in Tbilisi is a different story, and for those accustomed to luxury, the budget will be completely different.
Accommodation. If it's a modest hostel, expect to pay around 6-12 USD per day. If you are traveling to Tbilisi as a couple and plan to stay in a budget hotel, you will have to pay at least 42 USD per room per day. Multiply these numbers by the estimated number of days to get an approximate total amount.
Food. Both hostels and hotels usually include breakfast in the accommodation cost. However, you will need to take care of lunch and dinner yourself. You can get by with buying khachapuri or regularly dining in local cafes. In any case, budget at least 15-30 GEL per person per day.
Transportation. If you plan to not only explore Tbilisi but also visit different interesting places in Georgia, it makes sense to rent a car (especially if you are traveling in a group). Otherwise, public transportation will suffice: a single metro or bus ride costs 0.5 GEL, while a marshrutka (minibus) ride costs 0.8 GEL (if you plan to take multiple trips, it's better to buy a transportation card).
Tours, entertainment, shopping. To bring back some memories from your vacation in Tbilisi, check the prices for wine tours and souvenirs. It might be worth investing in a group tour of the city or its surroundings. In total, this could amount to an additional 100-200 GEL.
