Cumulative benefit crossover

Social Security Break-Even Calculator

Compare the payments received sooner with the larger monthly amount available from waiting, with an optional portfolio-return sensitivity test.

Private by design. Your birth date, earnings, and results stay on this device.

Step 1

Your timeline

Date of birthMM/DD/YYYY

Use the U.S. month/day/year format.

Dollar displayConstant formula dollarsExcludes future COLAs and inflation.Future dollarsApplies the visible 2.4% annual COLA assumption.

Planned stop-work year Optional. Future earnings phases must end by this year; claiming can happen later.

Step 2

Covered earnings

Earnings history — one “year, amount” per lineTreat omitted years as $0. I reviewed my earnings record.

Step 3

Future earnings phases

Model full-time, part-time, or zero-income periods separately. Leave this section empty if you do not want to project future earnings.

Portfolio-adjusted comparison

Include an illustrative portfolio returnModels each benefit dollar as money invested or left in your retirement portfolio.

How the break-even estimate works

For each claiming date, the calculator builds a benefit stream from the selected claiming month. It then finds the first month when the cumulative value of the later stream equals or exceeds the earlier stream.

Why your result can differ from a simple online chart

Your Primary Insurance Amount depends on your own highest 35 years of indexed earnings. Claiming months, zero-earning years, future earnings assumptions, and the selected dollar mode can all change the crossover.

Important limitation

A later break-even age does not mean one choice is universally better. Confirm official amounts with the Social Security Administration and consider qualified advice for a personal decision.

Optional portfolio-return scenario

If early benefits would reduce withdrawals or remain invested, enable the portfolio-adjusted comparison and choose a net annual return from 0% through 10%. It compounds every modeled benefit payment through the comparison age. The illustration assumes smooth returns and excludes taxes, fees, market volatility, and changes in spending behavior.
