How to save money? What's a best way of saving if you don't make good moneyFirst, download a personal finance management app like MoneyStream or Mint. Use it to analyze your spending behavior over the last few months.
Knowing your shopping and spending habits, you'll be able to get the best deal on a checking account. (If you already have an account, even a "free" account, but you're paying fees and charges each month, it's worth shopping around for a better deal. Those fees can add up to $300 per year!) You'll want to shop around a bit, as checking and savings accounts are more expensive (in terms of charges and fees) if you have less money.
If you can find a credit union near you that's partners with Kasasa (an online banking service that offers 4% interest on checking accounts with no monthly minimum, as long as you use the debit card 9 times per month), that's worth looking into. There aren't a lot of checking (or savings, or CDs) accounts that offer that much interest -- I think the national average is something like .17%.
Next, make a budget. Like I mentioned before, a personal finance app will help you do this quickly and smartly. They're designed by experts, and will automatically tell you things like, "You're spending too much on restaurants," or, "Your Visa bill is due next week." They'll make it easy for you to keep close track of your spending -- which is important, because small fees and everyday purchases add up a lot faster than we think.
