How much you can borrow depends on your personal situation and is determined by the bank. In general, you cannot borrow more than 33% of your annual income. For this, the bank looks at your income, minus your monthly expenses. What remains is your available budget. If you have other loans outstanding, that may affect the amount you are allowed to borrow.
