The full-retirement-age benefit, the birth year, two claiming ages, and the return the early checks earn; out: the break-even age with and without that return, and the two accumulated values crossing. In a frame it carries no cookies, no tracking, and a visible link back to the methodology. Your site has to allow frames; most do. The link that opens it in a small window is on the professionals page.

In plain words.
Start Social Security early and you collect smaller checks for more years; wait and you collect larger checks for fewer. The break-even age is where the totals cross. Most calculators stop there. This one also lets you assume the early checks were invested, which pushes the crossing later, because money in hand can grow.
Why it matters.
The plain break-even age flatters waiting. Adding a return on the early checks gives a fairer answer, and shows how sensitive the decision is to what your money earns.
An example.
Comparing a start at 62 with a start at 70, with the early checks earning nothing, the totals cross at about 80 and 4 months. Give the early checks a four percent return and the crossing moves several years later.
Where it stops.
It uses today's dollars, one person, and whole-year claiming ages. It ignores the earnings test if you keep working, tax, and benefits for a spouse or survivor.
