What This Social Security Calculator Shows

Income Gap

Social Security Calculator Example
Suppose your estimated monthly benefit at full retirement age is $2,200 and your full retirement age is 67.
If you claim earlier or later, the calculator estimates your adjusted monthly benefit, annual benefit, lifetime benefit, total retirement income, and monthly income gap or surplus.
Why Claiming Age Matters
Claiming age can affect monthly Social Security retirement benefits. Claiming before full retirement age may reduce monthly benefits, while delaying benefits may increase the monthly estimate.
The best claiming age can depend on health, work plans, income needs, taxes, spouse benefits, and overall retirement strategy.

Social Security may be one part of a retirement income plan. Many people also use pensions, 401K savings, IRA accounts, investments, annuities, or other income sources.
Comparing Social Security with desired monthly income can help identify whether additional savings or income may be needed.
