Sequence Risk Simulator

Explore how market timing affects retirement withdrawals, long-term portfolio survival, and financial independence.

What happens if retirement begins just before a major market downturn?

This simulator models monthly portfolio withdrawals and shows how inflation, taxes, market cycles, and sequence of returns risk can permanently affect retirement outcomes.

The simulator is especially relevant for early retirement and FIRE scenarios, where withdrawals begin long before traditional retirement age.

Before tax = fixed portfolio withdrawal.
After tax = fixed withdrawal after tax.

Market cycle

Simulate bull and bear market periods to explore sequence of returns risk.

What is sequence of returns risk?

Sequence of returns risk occurs when large market declines happen early in retirement, while withdrawals are already taking place.

Even if long-term average returns remain strong, early losses combined with withdrawals can permanently weaken a portfolio.

This is one of the main reasons why two retirees with the same average return can experience completely different outcomes.

Why early market declines matter

When withdrawals happen during a falling market, more shares must be sold to generate the same withdrawal amount.

This reduces the portfolio’s ability to recover during future bull markets.

The effect becomes even stronger when withdrawals increase with inflation over time.

Why this matters for FIRE and early retirement

Sequence risk becomes more important when retirement begins early.

Long withdrawal periods increase the portfolio’s exposure to market downturns, inflation, and prolonged periods of weak returns.

This simulator is designed to help visualize how different market sequences can affect long-term withdrawal sustainability.

How to use the simulator

The goal is not to predict the future, but to understand how sensitive retirement outcomes can be to market timing.
