Estimate your social security retirement benefits online

The Talking Books Librarian posted this great resource from the Social Security Administration and I'm reposting it here for your convenience.
Are you interested in estimating your social security retirement benefits? The Retirement Estimator website states:
"The Retirement Estimator produces estimates that are based on your actual Social Security earnings record. Retirement estimates are just that, estimates.They will vary slightly from the actual benefit you may receive in the future because:

• Your Social Security earnings record is constantly being updated;
• Our calculators use different parameters and assumptions (e.g., different stop work ages, future earnings projections, etc.);and Your actual future benefit will be adjusted for inflation.

You can use the Retirement Estimator if:

• You are not currently receiving benefits on your own Social Security record;
• You are not a Medicare beneficiary;
• You have enough Social Security credits at this time to qualify for benefits;
  and You are not eligible for a Pension Based on Work Not Covered By Social Security."
