Target retirement plan
The guardrail retirement strategy (often called the “guardrails” approach) is a flexible method for taking income from your portfolio in retirement.
Instead of sticking to a fixed withdrawal rate, like the traditional 4% rule, this approach adjusts your spending based on how your investments perform.
How Guardrail Strategy Works
A commonly referenced version of this approach is based on research by financial planners Jonathan Guyton and William Klinger.
Step 1: Set a starting withdrawal rate
You choose an initial withdrawal rate, such as 5% of your portfolio.
Step 2: Define guardrails
You establish thresholds around that rate, often:
- Lower guardrail: 4%
- Upper guardrail: 6% (These are typically set at ±20% around the target rate.)
Step 3: Review annually
Once per year, you check your current withdrawal rate based on your updated portfolio value.
- If your withdrawal rate rises above the upper guardrail, reduce spending (often by about 10%)
- If it falls below the lower guardrail, then increase spending (often by about 10%)
Step 4: Adjust over time
- Apply inflation adjustments within the rules
- Reassess annually rather than frequently
- Make gradual changes rather than reacting to short-term market swings
