First, find out your area of interest (subject) and country. Find out the average cost of living in that country. Every country has different standard living expenses.
Every country has a schedule for the intake of new students, like fall (September), winter (January), and summer. Keep an eye on admission deadlines.
Many private and public banks offer education loans; while choosing a loan, have a look at modes of repayment (EMIs after course completion) and interest rates. Always prefer fixed interest rates on loans.
To reduce your financial burden, look for academic scholarships. Some organisations like Tata Foundation and Aga Khan Foundation, are helping students who can't afford even the tuition fee because of the financial crisis. Approach them and seek aid.
To meet expenses, look for part-time work opportunities on or off campus, because most countries allow students to work 20 hours per week.
