Can I retire early and still get Social Security?

Yes. Retiring before your Social Security claiming age just means you live off other assets (taxable, 401(k)/IRA, Roth) until benefits begin. The FIRE Calculator models exactly this: you tell it when to start Social Security (62, 67, 70, or any age in between) and the projection draws down savings until benefits kick in.

Should I claim Social Security at 62, 67, or 70?

Claiming at 62 locks in roughly 70 % of your Full Retirement Age (FRA) benefit. Waiting to FRA (~67 for most current retirees) gives 100 %. Delaying to 70 gives ~124 %. The break-even age is typically late 70s — claim early if you need the cash flow or doubt your longevity; delay if you expect to live into your 80s and have other resources to bridge the gap.

How does Social Security affect my FIRE number?

It lowers it. Every dollar of expected Social Security is a dollar your portfolio doesn't need to fund. A retiree expecting $30k/year in Social Security from age 67 can run a portfolio simulation with ~$30k less in modelled annual withdrawal after that age. The Wealth Plan Builder shows this year-by-year.

What if Social Security gets cut?

The OASI trust fund is currently projected to be unable to pay full benefits some time in the 2030s; under current law, benefits would automatically reduce by ~17 – 23 %. Conservative planners model 75 – 80 % of scheduled benefits as a stress test. RetireCrunch lets you set the benefit amount manually so you can run this scenario.

Does Social Security count for the 4 % rule?

Indirectly. The 4 % rule applies to your portfolio. Social Security is a separate income stream that REDUCES the amount your portfolio needs to produce. If you spend $60k/year and get $30k from Social Security, your portfolio only needs to fund $30k — which can support a much smaller nest egg than $60k would imply.

How does this compare to claiming-strategy tools like OpenSocialSecurity?

Tools like OpenSocialSecurity optimize Social Security claiming itself — when to claim for max lifetime benefit. RetireCrunch is a broader retirement projection that integrates Social Security as one of many inputs (alongside 401(k), IRA, taxes, healthcare, etc.). Use both: pick a claiming age with OpenSocialSecurity, then test the full plan in RetireCrunch.

The early-retirement bridge problem

If you retire at 50 and claim Social Security at 67, you have a 17-year bridge to fund entirely from savings. Those years also have to cover pre-Medicare healthcare (until 65) and the Roth-conversion window where strategic tax planning can save tens of thousands.

RetireCrunch's FIRE Calculator (US mode) and Wealth Plan Builder both model this bridge explicitly: separate accumulation and decumulation phases, configurable Social Security claim age, ACA-era healthcare cost ranges, and federal + state tax brackets. The year-by-year projection shows exactly when the bridge ends.

Three claiming-age strategies

Claim at 62 — Locks in ~70 % of your Full Retirement Age (FRA) benefit. Right if you need the cash flow, doubt your longevity, or want to preserve other assets.
Claim at 67 (FRA) — 100 % of your scheduled benefit. The default for most planners. Pairs well with a 17-year bridge from age 50.
Claim at 70 — ~124 % of FRA benefit. Right if you expect to live into your 80s and have non-Social-Security resources to bridge ages 67 – 70.
