Coast FIRE Number at 35: How Much to Have Invested
At 35, an example saver needs about $231,377 invested to coast to retirement with no new contributions - and across real market history that plan held up about 82% of the time.
That's roughly what an example saver - $40,000/yr spending, a 5% real return, retiring by 65 - would need invested at 35 to stop contributing and still reach a $1,000,000 target through growth alone. These figures are computed at build time from Coastward's real-history engine, not hand-picked.
What coasting at 35 actually means
35 is the hinge. Thirty years is still ample runway, but the coast number climbs noticeably versus your twenties: every year you wait, compounding has less time to work and the figure you need invested today rises. It's still very achievable, and still early enough that a rough first decade after you stop saving usually has time to recover.
The honest part most calculators skip: $231,377 is the straight-line answer. When we replay that exact plan across thousands of real market sequences - crashes in their true order - it reached retirement intact in about 82% of histories. A coast number isn't a guarantee, it's a probability. See how that's computed →
How 35 compares with other ages
Wait until 40 and the same example saver needs $295,303 invested, about 28% more, because growth has 5 fewer years to work. Start earlier, at 30, and the number drops to $181,290, roughly 22% less.

Same example saver at every age - $40,000/yr spending, a 5% real return, retiring by 65. Only the starting age changes, so the rising coast number is purely the cost of having fewer years for growth to work.

Is 35 too late to Coast FIRE?
Not at all: 35 leaves about 30 years of growth, enough that coasting is squarely realistic. The coast number is higher than in your twenties because there's less time for compounding, but there's still real margin for a bad market stretch, which the success rate on this page quantifies.
