FAQ

What is the 4 percent rule?

The 4 percent rule says a retiree can withdraw 4 percent of their starting portfolio in year one, adjust that dollar amount for inflation each year, and have high odds of not running out over a 30-year retirement. It comes from the Trinity Study.

Is the 4 percent rule still safe for early retirement?

For 30-year retirements, yes, in most historical scenarios. For 40 to 60-year early retirements, many planners drop to 3 to 3.5 percent. Current high valuations also argue for a more conservative start.

What is a safe withdrawal rate for a 50+ year retirement?

Research by Karsten Jeske (Big ERN) and others suggests 3.25 to 3.5 percent as a more defensible starting rate for very long retirements, with the willingness to cut spending if markets fall early.

How do guardrail withdrawal strategies work?

Guardrails (Guyton-Klinger rules) let you start at a higher rate (4.5 to 5 percent) but cut spending when the portfolio drops past a threshold and allow raises when it grows. The calculator shows these dynamic rules against historical data.

What's the difference between fixed, variable, and guardrail withdrawals?

Fixed withdraws the same inflation-adjusted dollar amount regardless of markets. Variable takes a fixed percentage of current portfolio value (income fluctuates). Guardrails use a fixed amount most years but adjust up or down when portfolio value crosses pre-set thresholds.
