The U.S. Social Security Administration has a several helpful calculators plus explanations on how to figure your Social Security benefit based on when you retire and how much you have earned over the highest 35 years of income subject to Social Security taxes. The following options exist:
* a worksheet you can do on paper
* a quick online calculator that does not require you to log in to your account
* a detailed calculator downloadable to your computer
* If you are willing to set up online access to your own account, an online calculator will do some figuring based on actual income over your working career.
Links to these are in the Additional Resources section.
The government website also gives a simplistic example showing that if you start getting benefits at 62, the amount is reduced by 25 percent. If you wait until 70, the benefit is 32 percent more than at the current full retirement age of 66. If you really want to know the full financial impact on your future income under Social Security, using these calculators is only the beginning.
