About Social Security Estimate Calculator

The benefit starts from a progressive formula on average indexed monthly earnings: 90% of the first bend point, 32% of the next band and 15% above it. Claiming before full retirement age reduces it permanently, while delaying adds roughly 8% a year.

Formula

Benefit formula

PIA = 90%×first band + 32%×second band + 15%×remainder, then adjust for claiming age

Frequently Asked Questions

Why is the formula progressive?

It deliberately replaces a larger share of income for lower earners.

Is delaying worth it?

Delaying raises the monthly amount for life, so it pays off if you live beyond roughly your early eighties.
