To estimate your living costs while studying abroad, consider factors like accommodation, food, transportation, health insurance, and personal expenses. Research online resources provided by universities or government agencies of your chosen country. They often offer cost of living breakdowns. Reach out to current international students or alumni to get firsthand insights. Use cost of living calculators available online that take into account your destination and lifestyle preferences. Also, factor in exchange rates and potential inflation. Building a budget spreadsheet can help you track expenses and plan effectively. Remember that costs can vary based on location and personal choices.
