It is very individual and depends on your income and necessary payments you make every month. But let us give you a general percentage of money you can spend on gambling — 5%-15%. So for example, if you earn $3,000 a month, you can take from $150 to $450 for gambling each month. But you need to consider your own financial situation. For example, if you have a loan to pay for your car or your apartment rent is big, and so on, you need to pay them first. And only then you can calculate your spare money for online casino games.
