2026 EDITION
Retirement
Build it. Spend it. Pass it on.
The decisions that matter most — in brief. For everything else, read the guide.
By Nachi Nachiappan, in collaboration with Claude · Companion to the drawdown calculator
THE BIG PICTURE
Retirement is three problems, not one
Most planning obsesses over the first. The second is where fortunes are made or lost.
BUILD
Accumulation
Save in the right accounts, in the right order — capturing every match and tax break along the way.
Part I
SPEND
Decumulation
Turn the pile into a paycheck that lasts — net of taxes, Medicare, inflation, and a long life.
Parts II–III
PASS ON
Legacy
Leave what's left the tax-smart way — the step-up and Roth to heirs, the pre-tax to yourself.
Part IV
RETIREMENT · A Field Guide
2
FOUNDATIONS
Groundwork
Before the three problems: save enough, invest it well, and let compounding do the heavy lifting.
3
FOUNDATIONS · THE GROUNDWORK
Get the basics right first
1
Save about 15% of gross — and start early
Aim for ~15% including the match — roughly 10× salary by 67. Milestones: 1× by 30, 3× by 40, 6× by 50. An early start beats a bigger contribution later.
2
Invest broadly, cheaply — and stay put
Own the whole market with low-cost index funds; time in the market beats timing it. A 1% yearly fee can quietly cost six figures over a few decades.
3
Let compounding do the work
At ~7% real, money doubles about every decade. No 20-year stretch in a century of history has lost money in a diversified stock portfolio.
4
The mortgage: a guaranteed, risk-free return
Prepaying earns your interest rate with no risk — compelling above ~6%, a personal call at 4–6%, skip it below ~4%. For most: invest now, arrive mortgage-free.
RETIREMENT · A Field Guide
4
PART I · ACCUMULATION
Building the Pot
Save in the right accounts, in the right order — and let tax-advantaged compounding do the work.
5
PART I · THE SAVINGS ORDER
Save in the right order — the waterfall
1
Capture the full employer match
It's free money — often an instant 100% return. Skipping it is declining part of your salary.
2
Fill tax-advantaged space
Max the 401(k), then IRA/Roth, and the HSA — decades of sheltered, compounding growth.
3
Then invest in taxable
Flexible, lightly taxed on gains, and it earns a step-up in basis for your heirs.

PART I · WHICH BUCKET
Pre-tax vs. Roth — and the stealth HSA
The core bet: your tax rate, now vs. later
Pre-tax — deduct now, taxed later. Best when your rate will be lower in retirement.
Roth — taxed now, grows and withdraws tax-free. Best when your rate will be higher or similar — and it never has RMDs.
Hold all three — pre-tax, Roth, taxable — for tax diversification you'll exploit later.
The HSA
The only triple-tax-advantaged account
Invest it, don't spend it — run it as a stealth retirement fund for later healthcare.
RETIREMENT · A Field Guide
7
PART I · THE GUARANTEED BASE
Social Security: your inflation-linked floor
Earned by working
40 credits (~10 years) qualify you; your benefit is built from your highest 35 years of earnings, run through a progressive formula.
It protects your spouse
A spouse gets up to 50% of the higher earner benefit; a survivor keeps up to 100% — so the higher earner's timing echoes across two lives.
Full retirement age 67, plus a COLA
Claim from 62 to 70; benefits rise each year with a cost-of-living adjustment (2.8% for 2026) whether or not you've claimed.
THE PIA FORMULA
90% of the first $1,286
32% up to $7,749
15% above that
The “bend points” reset every year to average wage growth. The rates are fixed in law — the formula deliberately replaces more income for lower earners.
RETIREMENT · A Field Guide
8
PART II · DECUMULATION
Turning Savings into a Paycheck
The hard, under-taught problem — a system of interacting risks, and the tax levers you finally control.
9
PART II · HOW MUCH CAN YOU SPEND?
The 4% rule — a starting line, not a law
A SUSTAINABLE FIRST-YEAR WITHDRAWAL
4% → 4.7%
Bengen's original 4% — and his updated “Universal SAFEMAX” of 4.7%.
Where it came from. The worst-case historical retirement that never ran dry — a floor, not a forecast.
It ignores order. A fixed rate says nothing about the sequence of returns — the real danger (Part II).
Be flexible. Trimming spending in bad early years does more for success than any single “magic” rate.
RETIREMENT · A Field Guide
10
PART II · THE RISKS THAT COMPOUND
Sequence & longevity — the long-run threats
Sequence risk
Bad returns early — while you're withdrawing — do permanent damage. It's the danger a flat 4% rule ignores entirely.
The fragile decade
The first 5–10 years decide the outcome. Hold 1–3 years of spending in cash and stay flexible, so you never sell stocks into a crash.
Longevity
The master risk that multiplies the others. Plan for a long life — delayed Social Security, a cash buffer, and longevity annuities are the hedges.
RETIREMENT · A Field Guide
11
PART II · THE REAL ENEMIES
Inflation — and healthcare, which is worse
Your inflation number is wrong
Retirees spend differently than the CPI basket assumes — more on health and housing.
Plan for a rising spending line over 30 years, not a flat one.
Healthcare inflates faster
Medical costs climb roughly 5–6% a year — outpacing general inflation for decades.
It's a near-certain expense — roughly $172,500 per person over retirement: budget it as its own line, not a rounding error.
RETIREMENT · A Field Guide
12
PART II · YOUR NEW SUPERPOWER
In retirement, you control your tax bill
For the first time, you choose how much taxable income to realize each year. Use it.
Smooth the rate, fill low brackets
Realize a steady, moderate income every year instead of swinging from near-zero to a spike.
Mind the “tax torpedo”
Extra income can make more of your Social Security taxable — a hidden jump in your real rate.
Harvest the 0% gains bracket
Low-income years can let you realize long-term capital gains at a 0% federal rate.
THE GAP YEARS
The window between leaving work and starting Social Security / RMDs is often your lowest-tax era.
Deliberately pulling or converting income to fill your cheap brackets now avoids a much bigger bill later. It's the hinge of the whole spending plan.
RETIREMENT · A Field Guide
13
PART II · TWO LEVERS TO MASTER
IRMAA cliffs & Roth conversions
IRMAA: the Medicare cliff
An income-based surcharge on Medicare premiums — and it's a cliff: one dollar over a threshold bumps the whole tier.
It uses a two-year lookback, so plan income two years ahead — tier 1 starts at $109k single / $218k joint.
Roth conversions
Move pre-tax money to Roth in low-tax gap years to defuse future RMDs, IRMAA, and the tax torpedo.
Every dollar converted leaves the RMD machine — and Roth has no lifetime RMDs.
RETIREMENT · A Field Guide
14
PART II · TIMING THE GUARANTEED CHECK
When to claim Social Security
Delaying is buying more inflation-protected, guaranteed income — the best longevity insurance sold.
62
Earliest — permanently reduced
67
Full retirement age
70
Maximum — largest check
≈ +8% per year of delay
The higher earner's decision is a two-life decision. A survivor inherits the larger of the two benefits — so delaying to 70 maximizes not just your check, but your spouse's income for the rest of their life.
RETIREMENT · A Field Guide
15
PART II · SPEND IN THE RIGHT ORDER
Withdrawal sequencing & RMDs
Fill the brackets, don't empty the buckets
The naive “taxable first, Roth last” order wastes low brackets early and detonates RMDs later. Instead, realize a steady, moderate income every year.
RMDs eventually force your hand
Required distributions begin at 73 (rising to 75) and grow as you age — a large pre-tax pile becomes a tax spike. Shrink it early; QCDs give to charity tax-free.
It's the hub of the whole plan
Sequencing ties together Roth conversions, Social Security timing, IRMAA, and RMDs — one coordinated income strategy, not five separate ones.
RMDs BEGIN AT
73
rising to 75 by 2033
Miss one and the penalty is 25% (10% if fixed promptly).
RETIREMENT · A Field Guide
16
PART III · ACCESS
Retiring Early
Bridging the years before 59½ without the 10% early-withdrawal penalty.
17
PART III · REACHING YOUR MONEY BEFORE 59½
Two ways past the 10% penalty
Rule of 72(t) / SEPP
Substantially Equal Periodic Payments from an IRA — at any age.
Powerful but rigid: a fixed schedule you must hold for 5 years or until 59½. “Busting” it triggers retroactive penalties.
The Rule of 55
Penalty-free withdrawals from your current employer's 401(k) if you leave that job at 55+.
Flexible — no fixed schedule. The trap: don't roll it to an IRA first, or you lose the option.
RETIREMENT · A Field Guide
18
PART IV · INHERITANCE
Passing It On
Whatever you don't spend passes to others — and how it's taxed depends entirely on the account it sits in.
19
PART IV · THE TAX-SMART HANDOFF
It's the step-up, not the estate tax
2026 ESTATE-TAX EXEMPTION
$15M
per person — so federal estate tax is irrelevant for nearly every family. The real game is income-tax character.
Leave to heirs: taxable brokerage assets (they get a step-up in basis — a lifetime of gains erased) and tax-free Roth.
Spend or convert yourself: pre-tax IRA/401(k) dollars — heirs owe ordinary income tax on them and must empty the account within 10 years.
Note: IRAs and annuities get no step-up — a key reason to draw them down first.

20
PART V · BEYOND THE MONEY
Beyond the Money
The money is only the means. Purpose, people, health, place, and a clean handoff are the ends.
21
PART V · WHAT MONEY CAN'T BUY
Purpose, people, and health
Purpose
A job quietly supplies identity, structure, and contribution — all end the same Friday. Retire toward something; expect the early dip and plan to reinvent.
People
Relationships are the strongest predictor of a happy old age — loneliness rivals smoking for mortality risk. Work was your social network; rebuild it on purpose.
Health
Movement is the closest thing to a longevity drug — aim for ~150 min/week plus strength and balance. A sense of purpose lowers mortality on its own.
RETIREMENT · A Field Guide
22
PART V · THE LATER YEARS
Where you'll live — and handing over the reins
Where you'll live
Housing is a continuum: aging in place → downsizing → assisted living → memory and skilled care.
About 7 in 10 who reach 65 will need long-term care, and Medicare doesn't cover custodial care. CCRCs bundle the whole ladder for a large entry fee — decide before a crisis forces it.
Handing over the reins
Five documents, two buckets: a living will & health-care proxy; a durable financial POA, a will, and often a revocable trust.
The durable POA is the most-forgotten and most-needed. Consolidate accounts, name beneficiaries (they override the will), and keep one findable legacy folder.

FROM READING TO DOING
Your Action Plan
The highest-leverage moves from each part of the financial plan — what to actually do, with the 2026 numbers that matter.
24
ACTION PLAN · PART I
Accumulation — build the pot
1
Capture the full employer match
It's free money — an instant ~100% return. Never leave any match on the table.
2
Max tax-advantaged space
401(k) $24,500 (+$8,000 at 50+, +$11,250 at 60–63); IRA $7,500 (+$1,100 at 50+).
3
Use the backdoor Roth if you're over the limits
Fund a nondeductible IRA, then convert — but mind the pro-rata rule.
4
Max the HSA — the only triple tax break
$4,400 self / $8,750 family (+$1,000 at 55+). Invest it; pay medical bills out of pocket.
5
Build all three tax buckets
Pre-tax, Roth, and taxable — the tax diversification you'll exploit in retirement.
RETIREMENT · A Field Guide
25
ACTION PLAN · PART II
Decumulation — the spend-down
1
Pick a withdrawal rate on purpose
Start near 4–4.7%; use 3.25–3.5% for 40-year horizons. Stay flexible in bad years.
2
Budget healthcare as its own line
~$172,500 per person over retirement — inflate it at 5–6%, not 3%.
3
Work the gap years
Before Social Security and RMDs, fill low brackets — Roth-convert to the top of the 12% bracket.
4
Mind the IRMAA cliffs
Tier 1 hits at $109k single / $218k joint on a 2-year lookback. Convert to the line, not over it.
5
Delay the higher earner Social Security to 70
About +8%/yr of delay — and it sets the survivor benefit for both lives.
6
Sequence to fill brackets; shrink pre-tax before RMDs
RMDs begin at 73→75; once 70½, give with QCDs (up to $108,000).
RETIREMENT · A Field Guide
26
ACTION PLAN · PART III
Early access — before 59½
1
Prefer the Rule of 55 if you qualify
Penalty-free from your current 401(k) if you leave at 55+. Don't roll it to an IRA first.
2
Use 72(t) / SEPP for IRA access at any age
Substantially Equal Periodic Payments — split the IRA first, and never bust the schedule.
3
Bridge health coverage to 65
COBRA, a spouse's plan, or ACA — manage MAGI to capture income-based premium tax credits.
4
Size withdrawals to your bracket
Every dollar is ordinary income; don't spike your rate just to reach money early.
RETIREMENT · A Field Guide
27
ACTION PLAN · SURVIVING THE LONG RUN
Risk — survive the long run
1
Defend the fragile decade
The first 5–10 years drive success — a bad early sequence does permanent damage.
2
Hold a 1–3 year cash buffer
So you never have to sell stocks into a crash to fund spending.
3
Pre-commit to flexibility
Decide now what you'll cut, and by how much, after a bad start.
4
Plan to 90–95+
For couples, plan to the second death — longevity multiplies every other risk.
5
Keep growth for the long tail
Stay diversified in equities and cut costs — a century of data rewards patience.
RETIREMENT · A Field Guide
28
ACTION PLAN · PART IV
Inheritance — the tax-smart handoff
1
Leave the step-up assets to heirs
Taxable brokerage gets a basis step-up at death — a lifetime of gains erased.
2
Leave Roth to heirs too
It passes income-tax-free, with 10 more years of tax-free growth.
3
Spend or convert the pre-tax yourself
Heirs owe ordinary income on IRA/401(k) and must empty it within 10 years.
4
Give from the IRA with QCDs
After 70½, route gifts directly — tax-free, and it counts toward your RMD.
5
Don't over-plan for estate tax
$15M/person exemption ($30M couple) — the real game is income-tax character.
