Annual % you can withdraw from a portfolio with high probability of never running out. The Trinity Study popularised 4%; conservative planners use 3%–3.5%.
The Safe Withdrawal Rate is the percentage of your portfolio you can withdraw each year in retirement with a high probability of not running out of money, even if markets crash or you live longer than expected.
It's the foundation number of every retirement plan. Multiply your annual expenses by (100 ÷ SWR%) and you have your FI number: the target portfolio size at which you can stop working.
The Trinity Study (1998, updated since) analysed historical 30-year retirement periods in US markets. A 4% initial withdrawal, adjusted annually for inflation, held up across nearly every starting period. Even retirees who began in 1929 or 1973 saw their portfolios survive 30 years.
The 4% number assumed a 50/50 to 75/25 stock/bond portfolio. More-aggressive portfolios had higher success rates over long horizons; more-conservative ones did worse against inflation.
Long horizons: FIRE retirees with 40 to 50 year horizons need more buffer than 30-year retirees. 3.5% has near-100% success in historical simulations.
Lower expected returns: many analysts model 2020s+ markets at 4% to 5% real returns vs the historical 6% to 7% real. Lower returns demand lower withdrawal rates.
Sequence of returns risk: bad market years early in retirement disproportionately damage a portfolio. A flexible withdrawal strategy (3.5% in down years, 4.5% in up years) can outperform a static 4%.
CPF LIFE floor: from age 65, CPF LIFE provides a meaningful base income that reduces what your portfolio must produce. A couple at full ERS receives roughly S$6,900 / month, which covers essentials before any portfolio withdrawal.
Tax-free dividends: Singapore equities, S-REITs, and most ETFs (with correct domiciling) generate tax-free dividend income for residents. This effectively raises your usable SWR by 0.5% to 1%.
No mandatory minimum withdrawals from SRS until your penalty-free age (62, 63 or 64); flexible 10-year withdrawal window thereafter. Lets you spread distributions across low-tax-rate years.
Healthcare costs: rising MediShield Life and IP premiums in your 60s–80s can outpace inflation. Build a separate medical-cost reserve outside the main SWR portfolio.
The percentage of a retirement portfolio you can withdraw each year, adjusted for inflation, with a high probability of not running out of money over a 30+ year retirement. The traditional benchmark is 4%, popularised by the Trinity Study.
Conservative planners targeting longer retirements (40 to 50 years, common in FIRE) use 3% to 3.5% to add safety margin against sequence-of-returns risk and the prospect of lower forward returns than historical averages. The trade-off is a higher FI number requirement.
Annual expenses ÷ SWR. At 4% SWR with S$48,000/year expenses, FI number = S$1.2M. At 3.5% it's S$1.37M. At 3%, S$1.6M. The lower the SWR, the more capital you need to fund the same lifestyle.
Yes, significantly. CPF LIFE payouts from age 65 reduce what your private portfolio has to fund. If CPF LIFE covers S$2,000/month of essentials, your private SWR target shrinks accordingly. Many Singaporeans apply a 4% SWR to the gap only.
