The S&P Hit Record Highs 23 Times. You Might Have Already Saved Enough.

The S&P 500 crossed 7,600 for the first time on June 2, 2026 — its fifth straight all-time high, and by one count its 23rd record high of the year. Step back and the run is hard to absorb. Five years ago the index sat at 4,200. A year ago, 5,900. If you stayed invested through it, your portfolio may have done something you never noticed: grown past the point where it needs you anymore.

There's a milestone in personal finance almost nobody celebrates, because almost nobody checks for it — the moment your existing investments are large enough to grow into your retirement goal on their own, with not one more dollar from you. It has a name: Coast FIRE. After a five-year run like this, more people have crossed it than realize.

That's not a reason to celebrate blindly. It's a reason to run one number.

The milestone nobody tells you about

Coast FIRE is the point where your current savings, left alone to compound until retirement, reach your target without further contributions. You haven't retired. You haven't even stopped working. You've just stopped needing to invest — your past saving already bought your future its ticket.

The math is simpler than it sounds. Take what you want at retirement, discount it back to today at a reasonable return, and you have your Coast FIRE number. Above it, you've coasted. Below it, you know exactly how far is left.

So have you crossed it? That's a calculation, not a guess, and it takes about a minute. The Coast FIRE Calculator runs it from three inputs: what you have, when you'll retire, and the return you assume.

Try this. Say you're 35 with $200,000 invested, and you want $1.5 million by 65. At a 7% annual return, that $200,000 grows to roughly $1.5 million on its own over 30 years — zero new contributions. If that's you, you hit Coast FIRE with no finish-line banner. Put your own balance, age, and target into the Coast FIRE Calculator and find out whether your past self already did the hard part.

The catch: don't declare victory on a frothy market

Here's the honesty the headline demands. The same run that may have carried you to Coast FIRE has left stocks expensive — by the Shiller CAPE ratio, the only time the market was pricier was 2000, right before the dot-com crash. That doesn't guarantee a crash. It does mean the 7% you just enjoyed is not a law of nature.

Coast FIRE math is only as good as the return you feed it. Assume the boom continues and you'll talk yourself into coasting on a number that needs a calmer decade to actually arrive. So use a conservative return — many planners model around 5% real, not 7% nominal — and keep a margin. Then stress-test the plan in the Retirement Calculator, which shows what a flat or down decade does to a portfolio you've stopped feeding.

If your number holds at a conservative return, it's real. If it only works at 7% forever, you're close, not finished.

The two ways Coast FIRE backfires

Two mistakes bracket this idea. The first is never checking — grinding out extra contributions for years after your portfolio could already coast, trading freedom you've earned for a figure you never calculated. The second is the opposite: declaring Coast FIRE on a record-high market and easing off entirely, then watching a correction reset the math.

Time in the market is what built this milestone in the first place — the people who reached it didn't time the run, they simply stayed in it. The same discipline that got you here is what protects the number now.

Reaching Coast FIRE doesn't mean quit your job — you still need income to live on. It means you've earned the right to stop worrying about retirement contributions and point that money at life now, or at a bigger goal. That's real freedom. Just make sure you've actually reached it, at a return you'd trust in a bad year.

Run your number before the next headline

The record highs are a fact. Whether they carried you across your own finish line is a question only your numbers answer. Don't let a 7,600 print make you feel either rich or behind — check.

Find your Coast FIRE number in the Coast FIRE Calculator, using a return you'd believe in a recession. Then pressure-test it in the Retirement Calculator. You may have already saved enough — you deserve to know it, or to know exactly how close you are.
