All Retirement Simulation Guides

Every guide on Retirement Odds Lab, grouped by what it covers. Each one uses the same engine and assumptions as the calculator.

Basics

What Is a Monte Carlo Simulation in Retirement?

A plain-English guide to how a Monte Carlo simulation tests a retirement plan against thousands of market paths, with a worked example and its limits.

Basics

What Is a Good Monte Carlo Success Rate?

Is 70, 80 or 95 percent a good retirement success rate? What the number means, why 100 percent is not the goal, and why scores differ between calculators.

Basics

How to Pick a Monte Carlo Retirement Calculator

A checklist for judging any Monte Carlo retirement calculator: assumptions shown, inflation, correlations, trials, spending, privacy, and how this one fares.

Basics

How This Retirement Simulation Works

The model behind the calculator: return assumptions with sources and dates, order of cash flows, correlations, trials, and the known limits of the method.

Risk

Sequence of Returns Risk Explained

Two portfolios can earn the same average return and end up far apart. See how the order of returns drives retirement outcomes, with a worked example.

Risk

Monte Carlo vs Historical Retirement Simulation

Monte Carlo draws random returns; historical tools replay real years. How each works, where they agree, and why their answers can differ for the same plan.

Risk

What a Monte Carlo Simulation Cannot See

Inflation shocks, long lives, taxes, health costs, your own behavior and model error all sit outside most simulations. Here is what that means for your score.

Withdrawals

The 4% Rule vs Monte Carlo Simulation

Where the 4% rule came from, what it assumed, and how its success rate looks when a Monte Carlo model runs thousands of paths instead of the past alone.

Withdrawals

Safe Withdrawal Rate and Withdrawal Strategies

What a safe withdrawal rate is, why it is not one number, and how fixed, percentage and guardrail strategies behave when a simulation stresses them.

Withdrawals

How Long Will My Money Last in Retirement?

Worked cases show how starting balance, spending and market order change how long retirement savings last, each computed with the calculator's assumptions.

Withdrawals

Bucket Strategy for Retirement: Does It Work?

How the bucket strategy splits cash, bonds and stocks to manage a rough start to retirement, and what simulations say about it compared with a single mix.

Metals

Gold in a Retirement Portfolio: What Data Shows

What gold did in past rough decades, what it did not do, and how adding it to a simulated plan can raise or lower the odds depending on your assumptions.
