The amount that, left alone, grows into a full retirement corpus by itself. Reaching it means you can stop saving for retirement entirely and still retire on time, which is a milestone worth knowing about.

$261,165.20 today would grow to $1,500,000.00 by 60 with nothing further added. You have 150,000, so you are not yet coasting.
An estimate, not an offer or a guarantee. Projected returns assume the rate you entered holds for the whole term, which no market does.
This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for United States change on a published schedule; the effective date is shown on every rule-based tool.
Take the retirement target and discount it back to today at the real return. Anything at or above that figure will compound into the target without another dollar saved, so further saving buys an earlier retirement or a richer one rather than retirement itself. Because it is a discounting exercise, the number falls sharply the younger you are: thirty years of compounding does most of the work.
coast number = the retirement target discounted back at the real returnEach of these is asserted on every build. If a change to the engine ever moved one of these answers, the build would fail before the page could print it.
Coast number$261,165.20
60,000 / 4% = 1,500,000 at retirement, discounted at 6% for 30 years: 1.06^30 = 5.74349117, so 1,500,000 / 5.74349117 = 261,165.20. Worked separately in Python.
