If you put a huge sum of money in the appropriate spot, you can earn the highest interest rate, which will increase the amount of money you have by the end of the year. You have other options besides high-yield savings and checking accounts if you want to earn interest.
Look for checking accounts that provide welcome incentives and additional interest for the first banking year. Savings accounts typically pay a little less interest than money market accounts. You can open a CD if you don't believe you need any of the money in your savings. They provide the highest interest rates, but if you want to take some of the money out, there are significant fees.
