What is the Social Security Calculator doing with my numbers?

In plain language: The calculator estimates full retirement age from birth year, then applies early claiming reductions before full retirement age or delayed retirement credits after full retirement age through age 70. If the result seems too high or too low, first check whether each field expects a monthly amount, annual amount, dollar value, or percent.

What does this estimate leave out?

This does not access SSA records, earnings history, spousal benefits, survivor benefits, disability benefits, taxation, COLA changes, or official benefit estimates. Real finance decisions can also depend on fees, timing, local rules, credit details, and provider-specific terms.
