What we checked before giving you a number
The retirement savings question is one of the most studied problems in personal finance, and it's also one of the most distorted by financial industry incentives — many products benefit from people believing their number is higher than it actually is. We cross-referenced the peer-reviewed research behind the 4% rule with updates from independent retirement researchers, actual Social Security Administration data, and Bureau of Labor Statistics spending surveys of real retirees, rather than relying on any single brokerage's calculator or marketing material.

The Trinity Study and its updates reviewed The original 1998 research from Trinity University — and its multiple peer-reviewed updates through 2025 — continues to support a 4% initial withdrawal rate as sustainable over 30-year horizons for balanced portfolios in the overwhelming majority of historical scenarios.
-
Morningstar's 2024 safe withdrawal rate analysis consulted Morningstar's independent research suggests a slightly more conservative starting rate of 3.7% for new retirees given current valuations and lower projected bond returns — a meaningful difference for early retirees, less so for those with flexible spending.
-
BLS Consumer Expenditure Survey data for retirees examined Actual Bureau of Labor Statistics data consistently shows that households aged 65–74 spend roughly 75–80% of what they spent in their late working years, and spending typically declines further after 75 — contradicting the common industry assumption of 100% income replacement.
-
Social Security Administration benefit data verified The SSA's own data shows the average 2026 retirement benefit is approximately $1,978 per month — nearly $24,000 per year — which meaningfully reduces the savings burden for most middle-income households when properly factored in.
The right approach depends on your timeline and flexibility
There isn't one universal retirement number — but there are clear frameworks for different situations. Here's how to choose the right one for where you are.
Common approaches that lead people astray
A few deeply embedded pieces of conventional retirement wisdom turn out to be either wrong, outdated, or structured to benefit someone other than you.
-
Using "replace 80% of your pre-retirement income" as a target — This rule is industry shorthand that ignores what you actually spend. High earners who save aggressively may only need to replace 50–60% of their income; others may need 90%. Basing your number on income rather than spending can leave you either oversaving unnecessarily or dangerously undershooting.
-
Ignoring Social Security when calculating your number — Many retirement calculators and articles default to ignoring Social Security "because it might not be there," which dramatically inflates the savings target they present. Social Security is highly likely to remain solvent at meaningful benefit levels through your lifetime — the SSA's own trustees project it can pay roughly 83% of scheduled benefits even under the worst-case scenario without any Congressional action. Factor it in.
-
Planning for your retirement spending to stay flat (or rise) throughout retirement — Detailed research from the Employee Benefit Research Institute and David Blanchett at PGIM shows that real retiree spending typically follows a "smile" pattern — declining gradually in the middle years and rising again only in late retirement due to healthcare. Planning as if expenses stay constant tends to overestimate how much you need in your 60s and 70s.
-
Treating your home equity as a retirement backstop without a plan for it — Many people mentally count home equity as a retirement safety net but have no concrete plan to access it. Reverse mortgages are expensive and misunderstood; downsizing involves real costs and timing risks. Home equity can absolutely play a role in retirement, but it requires an actual strategy — not just a mental note.

I'd been using the "80% of income" rule for years and had a vague target of $2.2 million that felt impossibly out of reach. When I actually sat down and listed what we'd spend in retirement — no mortgage, no college costs, no work wardrobe — it was $58,000 a year. Our combined Social Security is going to be about $34,000. That means we need our portfolio to generate $24,000 a year. 25 times that is $600,000. We're almost there. I felt like I'd been lied to for a decade.

The 25x rule clicked for me when I stopped thinking about it as a savings target and started thinking about it as buying an income stream. I need $40,000 a year from my portfolio. $40,000 times 25 is $1 million. That's my number. Simple math I can actually track. I've gone from feeling paralyzed to having a clear goal with a timeline. The key was being honest about what I actually plan to spend — I had to cut some retirement fantasies out of the plan, but the number got real.

The 25x calculation gave me a number — $1.1 million — but I kept feeling uneasy because healthcare felt like a wildcard. I went and got a fee-only planner to stress-test the healthcare piece specifically, and she ran scenarios with long-term care costs that honestly scared me. The base 25x number is right for most of retirement, but I ended up wanting a separate $200,000–$300,000 earmarked specifically for potential LTC needs. So the method works, but I'd add: don't let the clean math make you forget the messy healthcare variable.
