Retirement
A field guide to building, spending, and passing on your savings
Retirement is really three problems, not one. First you build the savings. Then — the hard, under-taught part — you turn that pile into a paycheck that lasts the rest of your life. And finally you pass on what's left. This guide walks all three, and pairs with the calculator so you can stop reading about a decision and actually model it against your own numbers.

Introduction
Orientation
New here? Start with the big picture — why retirement is three problems rather than one, what the five parts cover, and how to read the guide alongside the calculator.
FOUNDATIONS
Financial Discipline
Groundwork
Part I picks the accounts you build the pot in; this section is about the habits and principles that decide how big that pot gets in the first place — the groundwork underneath the tax rules. How much to save and the discipline to sustain it, whether to steer spare cash into the mortgage, the handful of investing principles that quietly beat most professionals, and what a century of market returns shows about compounding and patience. The first three are told myths-and-facts style so the common traps are easy to spot.
F1How Much to Save — and the Discipline to Do ItThe 15% target and the age-based milestones, where the 10× rule really comes from, spending less than you earn, killing high-interest debt, why starting early beats saving more later, and what the FIRE movement's 50% savings rate actually buys.F2Should You Pay Off the Mortgage?The rate-arbitrage math, the real pros and cons, the peace-of-mind and sequence-risk case, the narrow exception where a kept mortgage is enhancing debt, and what the research does and doesn't show.F3Where to Invest: Diversification, Cost, and TimeThe four durable principles — diversify broadly, match risk to your horizon, stay invested through bad years, and keep costs near zero.F4The Power of Compounding and Historical ReturnsWhat a century of returns shows about compounding, patience, and honest expectations. PART I
Retirement Planning
Accumulation
The years before retirement are about two things: building the pot, and building it in the right accounts. Each pillar here has its own tax treatment, contribution limits, and rules — and using them in the right order (capture the match, fill tax-advantaged space, then taxable) and the right mix (pre-tax vs. Roth) sets up every decision in the rest of the book. The recurring ideas: tax-advantaged compounding, the free money of an employer match, tax diversification across buckets, and the inflation-protected foundation that Social Security and Treasury bonds provide.
1Employer Plans: The 401(k) and Its CousinsPayroll-deferred plans, the employer match, pre-tax vs. Roth, 2026 limits, vesting, and rollovers.2IRAs: Traditional and SpousalTraditional and Roth IRA mechanics, deduction phase-outs, and the spousal IRA that funds a non-earning spouse.3Roth Accounts and the BackdoorRoth basics and tax-free growth, income limits, the backdoor and mega-backdoor, and the pro-rata trap.4The HSA: Your Stealth Retirement AccountThe only triple-tax-advantaged account — and how to run it as a stealth retirement fund.5Social Security Basics: How Benefits Are Earned (and the Spousal 50%)How benefits are earned (credits, PIA, FRA) and the spousal benefit that tops a spouse up to 50%.6Personal Savings: Taxable Accounts, Treasuries, and Inflation BondsTaxable accounts, the 0% gains bracket, Treasuries, and inflation-protected TIPS and I bonds. PART II
Retirement Income
Decumulation
This is the harder, less-taught problem: turning a pile of savings into a paycheck that lasts the rest of your life. It's dominated by a system of interacting risks — inflation, healthcare, taxes, Medicare surcharges, market sequence, and longevity — and by the levers you finally control: which account to tap, when to claim Social Security, when to convert. These chapters cover safe withdrawal rates and the sequence-of-returns risk that shadows the fragile early years, the retiree-specific risks of inflation and healthcare, the guaranteed lifetime income you can add through pensions, annuities, and your home equity, the deliberate use of low-rate debt to fund a bad year without selling into it, the earned income of part-time work and how it ripples through Social Security, payroll tax, and Medicare, and the tax levers you finally control: bracket-filling, IRMAA-aware withdrawals, Roth conversions, Social Security timing, sequencing, the required distributions that eventually force your hand, and the state that taxes it all — closing with longevity, the master risk that stretches every other one.
7The 4% Rule, and How to Actually Execute ItWhere 4% came from, why Bengen now says 4.7%, and how to actually execute a withdrawal rate.8Sequence-of-Returns Risk and How to Blunt ItWhy order only matters once you're withdrawing — and the buffers, flexibility, guardrails, and borrowing that blunt it.9Inflation: Why Your Number Is Probably WrongWhy your inflation assumption is probably wrong — and the retiree-specific gap most plans miss.10Healthcare Costs and InflationThe $172,500 question: planning for medical costs that inflate faster than everything else.11Tax Optimization in RetirementUsing your new control over taxable income — brackets, the tax torpedo, and the 0% gains bracket.12IRMAA: The Medicare Surcharge CliffThe Medicare surcharge cliff, its two-year lookback, and how to plan conversions around it.13Roth ConversionsConverting pre-tax to Roth in low-tax years to defuse future RMDs, IRMAA, and the tax torpedo.14When to Claim Social SecurityClaiming from 62 to 70 as longevity insurance — and why the higher earner's timing protects both spouses.15Pensions: Guaranteed Income You Can't OutliveDefined-benefit basics, single-life vs. joint-and-survivor, lump-sum rollovers, the PBGC backstop, and how pension income is taxed.16Annuities: Buying Your Own Guaranteed IncomeSPIAs, QLACs, and the complex products in between — how they work, when they fit, and the qualified vs. exclusion-ratio tax rules.17Home Equity as Retirement IncomeReverse mortgages (HECMs), the tenure option and the standby line-of-credit buffer, tax-free proceeds, and the costs and pitfalls to weigh.18Strategic Debt in Retirement: Borrowing Instead of SellingWhy borrowing instead of selling blunts sequence risk, keeps income off your tax return, and preserves the step-up — and the callable-loan trap that can turn the whole strategy inside out.19Working in RetirementPart-time work and its four ripple effects — the Social Security earnings test, the FICA you still owe, the accounts you can keep funding, and Medicare past 65.20Withdrawal Sequencing Across Account TypesThe order you spend your buckets in — and why bracket-filling beats the naïve rule of thumb.21RMDs and SECURE 2.0When forced withdrawals begin, how they're computed, and how QCDs and conversions soften them.22State Taxes on Retirement IncomeHow states tax Social Security, pensions, and account withdrawals — the nine no-tax states, the estate-tax trap, and relocating the right way.23The Long Tail: Longevity Risk and the Retiree Inflation GapThe master risk that multiplies all the others — and the tools that hedge a very long life. PART III
Early Retirement
Access
Retiring before 59½ means bridging two different gaps: getting at your money without the 10% early-withdrawal penalty, and covering your own health insurance until Medicare begins at 65. Three routes unlock early access to your accounts — the rigid 72(t) schedule, the flexible Rule of 55, and a pre-planned Roth conversion ladder (alongside the Roth contributions you can always reach) — each powerful and each carrying a classic mistake that quietly forfeits it — and a fourth chapter tackles the pre-Medicare coverage bridge and the income-based ACA subsidies that make it affordable.
Whatever you don't spend passes to others — and two separate questions decide how well. First, how it's taxed: with the federal estate tax now irrelevant for nearly every family, the real game is income-tax character and the step-up in basis, so leave the step-up and tax-free assets to your heirs and spend down or convert the pre-tax accounts yourself. Second, how it's transferred: beneficiary designations, payable- and transfer-on-death registrations, deeds, and a revocable living trust decide whether it reaches your heirs privately and in weeks — or crawls through public, months-long probate.

The whole guide in one place — the durable ideas that run through every chapter, and a do-this action plan by part with the 2026 numbers that matter. Read it last as a recap, or first for the big picture.
PART V
Beyond the Money
The Good Life
The money is only half a retirement. This closing part covers the half a spreadsheet can't — the purpose, relationships, and health that most predict a good late life; the housing continuum and long-term care that decide where and how you'll live; and the directives, simplification, and legacy folder that let someone step in when you no longer can. Non-financial by design, and meant to be read as a coda to the plan.
30Retiring Toward Something: Purpose, People, and HealthThe non-financial half of retirement — replacing the identity, structure, purpose, and social ties that work provided, navigating the four psychological phases, and protecting the relationships and health that most predict a good late life.31Where You'll Live: Aging in Place, Downsizing, and CCRCsThe housing continuum for a long retirement — aging in place with modifications, downsizing, the Village model, and continuing-care retirement communities (CCRCs) — and where long-term care actually happens, from home to assisted living to nursing care. (Its costs, insurance, and Medicaid are in Chapter 10.)32Handing Over the Reins: Directives, Simplification, and LegacyThe documents and simplifications that let someone step in when you can't — health-care directives and a proxy, a durable financial power of attorney, consolidating accounts, naming a trusted contact, and the one folder your family will need.
