What's a safe withdrawal rate today?
By the RetireGlide Team · June 26, 2026
For a 30-year retirement, current research supports initial withdrawal rates around 3.7–4.3% of your starting portfolio, adjusted annually for inflation — lower for longer horizons, higher if you'll flex spending or have strong guaranteed income. There is no single safe rate; there's a safe rate for your plan.
The spread in those numbers isn't academic squabbling — each reflects a different assumption about the future, and the assumptions that matter most are yours.
Why published 'safe' rates keep changing
Bengen's original 1994 study found 4% survived the worst US historical sequence. Later work pushed the number both ways: Morningstar's recent state-of-retirement-income studies have landed between 3.7% and 4.0% using forward-looking return expectations, while Bengen himself has revised his own estimate above 4.5% with more asset classes. Historical-worst-case, forward-expectations, and flexible-spending frameworks are answering different questions — that's the whole disagreement.
The four inputs that set your rate
- Horizon — 4% math assumes ~30 years. Retiring at 50 pushes safe rates toward 3.25–3.5%; retiring at 70 supports well above 4%.
- Flexibility — willingness to trim 5–10% in bad markets is worth roughly 0.5–1.0 percentage points of starting rate. Rigid spending pays for certainty.
- Guaranteed income share — when Social Security and pensions cover your essentials, portfolio failure stops being catastrophic, justifying a higher rate on the remainder.
- Taxes and account mix — a withdrawal rate is pre-tax; the same rate funds different lifestyles depending on how much of the portfolio the IRS effectively owns.
From a rate to a plan
Withdrawal-rate research is calibration, not navigation. The operational version is a simulation of your plan — your accounts, taxes, Social Security timing, spending shape — that reports success odds and a safe spending range, then updates as reality unfolds. A rate is what you start with; a monitored range is what you live by.
Frequently asked questions
- Is 5% a safe withdrawal rate?
- For a 30-year fixed-spending plan, 5% historically failed in a meaningful minority of sequences. It can be defensible with substantial flexibility, a shorter horizon, or high guaranteed income — the way to know is modeling it, not hoping.
- Does the 4% rule include Social Security?
- No — it's a portfolio-only rule. Your withdrawal need is spending minus Social Security and pensions, which is why two retirees with identical portfolios can have very different safe rates.
- What withdrawal rate should an early retiree use?
- Most research points to 3.25–3.5% for 40–50 year horizons with fixed spending — or higher with guardrail-style flexibility. Early retirees benefit most from flexible frameworks because they have the most time to adapt.
