Safe Withdrawal Rate (SWR)

SWR is a planning rate used to estimate annual withdrawals that aim to keep retirement portfolios sustainable.

Connect retirement corpus size to spending durability under inflation and return-sequence uncertainty.

How It Works

SWR frameworks are scenario tools and do not guarantee outcomes in future market regimes.

Small starting-rate changes can materially affect long-horizon depletion risk.

Flexible spending policies usually improve plan durability versus rigid withdrawals.

Scenario

Retiree has $1,000,000 and uses a 4% initial withdrawal policy.

Outcome

Initial annual withdrawal is $40,000 before inflation adjustments.

Scenario

Same retiree uses 3.5% instead.

Outcome

Initial income is lower, but survival probability under adverse sequences often improves.

Is 4% always safe?

No. Sustainability depends on returns, inflation, spending flexibility, and horizon.

What improves SWR outcomes?

Dynamic spending guardrails and conservative assumptions improve resilience.
