How long will $1.5 million last in retirement?
$1.5 million clears the classic bar for a self-funded retirement: the 4% guideline alone produces $5,000/month, and Social Security stacks on top of it. The calculator below stress-tests your actual spending against this balance; the strategy notes cover the part most people at this level skip — the tax sequencing that quietly determines how much of the $1.5 million you actually keep.

Get the full picture →The numbers behind $1.5 million
- The 4% guideline puts $1.5 million's sustainable draw at $60,000/year — about $5,000/month before Social Security or pensions.
- At $3,750/month of net spending (5% real return), $1.5 million lasts 70+ (effectively indefinite) years; at $7,500/month it lasts 35.9; at $12,500/month, 13.9.
- Social Security changes the math more than returns do: a typical $2,000/month benefit reduces the draw on the portfolio dollar-for-dollar — spending $7,500/month with that benefit only pulls $5,500/month from savings.
- These figures are in today's dollars with returns treated as real (after inflation) — so "lasts 25 years" means 25 years of constant purchasing power, not nominal dollars.
- Sequence-of-returns risk is the wildcard a single average hides: the same average return with a crash in years 1–5 depletes a portfolio years earlier than the identical crash in years 15–20.
Strategy notes for a $1.5 million retirement
A portfolio in this range supports a genuinely comfortable retirement under the classic guidelines — the 4% rule alone generates more than the median American household's working income when you add Social Security. The planning problems shift from "will it last?" to efficiency: which accounts to draw first (taxable → traditional → Roth as a default ordering, with exceptions), how much to Roth-convert in the low-bracket years before required minimum distributions begin at 75, and how to manage realized income for ACA subsidies if you retire before Medicare at 65. Tax sequencing done well is worth six figures over a 30-year retirement at this asset level — it is the highest-paid hour of work you can do. The risk worth respecting is lifestyle creep at the start: the first years of retirement are when spending discipline is loosest and sequence risk is highest, an unfortunate combination. For $1.5 million specifically, the bracketing numbers worth memorizing: $3,750/month lasts 70+ (effectively indefinite) years on portfolio alone, and $7,500/month lasts 35.9 — your real plan lives between those lines once income is layered in.
Frequently asked questions
What monthly income does $1.5 million generate in retirement?
Using the 4% guideline, $1.5 million supports about $60,000 per year — $5,000/month — with historically high odds of lasting 30 years. A more conservative 3.5% rate, often recommended for retirements longer than 30 years, puts it at $4,375/month. Social Security and any pension add on top of that.
How long will $1.5 million last with Social Security included?
Much longer than the headline number, because the benefit reduces your portfolio draw dollar-for-dollar. Spending $7,500/month with a typical $2,000/month benefit only withdraws $5,500/month from savings, versus $7,500 without it. Use the "other monthly income" field in the calculator above to model your actual benefit estimate from ssa.gov.
Can $1.5 million run out in under 10 years?
Yes — overspending does it at any portfolio size. $1.5 million depletes inside a decade if net spending exceeds roughly $15,000/month sustained, or faster if a market crash lands in the first few years while withdrawals continue at full pace. That sequence-of-returns combination, not average returns, is what breaks retirements; a cash buffer covering 1–2 years of spending is the standard defense.
Is $1.5 million enough to retire on at all?
It depends on spending and what else exists: Social Security, a pension, a paid-off house. At $3,750/month of portfolio spending, $1.5 million lasts 70+ (effectively indefinite) years before any benefit is counted — and most households add $1,500–4,000/month of Social Security on top. The honest test isn't the balance, it's whether your real monthly budget minus guaranteed income stays under what the balance sustainably yields ($5,000/month by the 4% rule).
