Social Security Break-Even Calculator

Rules from 20 CFR 404 · reviewed September 6, 2026

Finds the age at which waiting to start Social Security pays off, including what the early checks could have earned. About

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. Everything it leaves out.

$

The figure on your Social Security statement for full retirement age. The break-even age does not depend on it, but the dollar amounts do.

Your full retirement age is 67.

Advanced: what the early checks could earn, and cost-of-living increases

What the early checks would earn if you invested them, or what you would keep earning on savings you did not have to spend. At 0% the tool simply adds up the checks.

Applied to both benefits each year. It barely moves the break-even age.

Waiting from 62 to 70 pays off if you live past
80 and 4 months
Claiming at 62 pays $1,750 a month. Waiting until 70 pays $3,100 a month. This counts the checks alone. Give the early checks a return under Advanced and the catch-up age moves later. By age 100 the totals are $799,750 from claiming early and $1,119,100 from waiting, so waiting comes out ahead.

The return you assume decides most of the answer. At zero, the break-even age lands in the early 80s for most pairs of claiming ages. At 4 percent it moves several years later. At 6 percent or more, waiting rarely catches up inside a normal lifetime. How long you live, a spouse's survivor benefit, taxes on benefits, and whether you would really invest the checks each move the answer in ways the slider cannot.

This uses the Social Security rules for early-claiming reductions and delayed-retirement credits, in dollars not adjusted for inflation, with every check earning the return you set from the month it arrives. It leaves out the earnings test, taxes on benefits, and spousal and survivor benefits. Educational, not advice.

This is a simplified model, not your actual tax return or plan. It only knows what you type in, leaves out rules that may apply to you, and cannot weigh the other facts and trade-offs a real decision depends on. Before you act, talk with a professional who knows your whole situation.
