The Estimate of Benefits report, which is the baseline most planners use to project Social Security benefits in retirement, has several important embedded assumptions that can affect what any given worker will actually receive. For example, the amount shown on the report at various retirement dates assumes the worker will continue working at the same covered income from now until that retirement date. Should the worker leave the labor force, or work at a higher or lower wage before collecting benefits, the estimate could be off.
