Getting a great interest rate on your savings can help you grow your nest egg quickly. Finding a high interest rate on a savings account takes a little research, but the financial rewards are well worth the required effort. Here are some tips to help you find a savings account with a high interest rate.Consider A Long Term Savings OptionIf you do not need to be able to access the money you have in savings, consider a long term savings account, such as a CD. When you put your money in a CD, you will not be able to access those funds for a predetermined length of time. The interest rates for these savings accounts are higher than traditional savings account options.Do Research OnlineIf you are just looking for a regular savings account that will allow you to access your money whenever you need it, you should do research online to compare savings account interest rates at different banks. Doing research online is generally faster than calling each bank individually. Make sure you read the fine print on any special offer being advertised by a bank. Some banks promise high interest rates but charge monthly account maintenance fees that offset the interest rate difference.Check Out Local Credit UnionsAnother option is to open a savings account at a local credit union. Credit unions are owned by the people who bank there, so interest rates are usually higher than they are at traditional banks. Some credit unions are not open to the public, but others are. Check out local credit unions to see if you could become a member and get a savings account with a high interest rate.Ask Your Current Bank For A Better RateIndividuals who already have a savings account with their bank but are unhappy with their current interest rate should ask their bank for a rate increase. Although the answer could be no, if you have a long standing relationship with your bank they might increase your rate because they want to retain your business. Ask your bank if they will give you a better savings account rate, and the answer might just be yes.
