Not a blog. Deep, sourced, honest answers to the questions that decide when you can retire and whether your plan holds up — each one paired with the real calculator behind the math, not just a rule of thumb.
A 30% drop your first year of retirement does far more damage than the same drop in year fifteen. Sequence-of-returns risk, explained plainly.
Why the timing of a crash matters more than the crash itself, and what a real stress test shows that an average-case projection can't.
A career break costs more than the missing paycheck — it can force an early 401(k) withdrawal. See your cash runway before the penalty wall, and the price in lower income or extra working years.
What a Monte Carlo simulation actually does, why an average-return projection can be dangerously optimistic, and how to read a success rate honestly.
Two plans can share the same success rate and have completely different risk underneath it. Why one number hides where a plan actually breaks.
Where the 4% rule actually came from, why a 40-50+ year FIRE-length horizon doesn't automatically get the same number, and how to find your own honest rate.
The static 4% rule vs. Guyton-Klinger guardrails, side by side — what flexible spending actually buys you, and what it costs.
Real historical years, not simulated ones — what actually happened to retirees unlucky enough to start in the worst stretches since 1928.
Why the same gross income can net very differently depending on account mix, withdrawal order, and which state you retire in.
The bet you're making when you convert, why "fill the bracket" is the classic play, and the IRMAA/ACA cliffs that can bite before your tax bracket does.
The backdoor Roth mechanism, and the pro-rata rule trap that catches people with existing pre-tax IRA balances.
The birth-year-dependent RMD start age under SECURE 2.0, why the first one is often bigger than expected, and how proactive conversions shrink it.
Asset location isn't asset allocation — same overall mix, but which account holds each piece changes what you actually keep after tax.
Single-filer brackets are roughly half as generous as married — but income rarely drops by half. The math is genuinely punishing, and plannable ahead of time.
State tax treatment of retirement income varies enormously — no-income-tax states, Social-Security-exempt states, and everything in between.
Sending your RMD directly to charity excludes it from AGI entirely — a real, often-overlooked advantage for anyone who gives and takes the standard deduction.
How ACA premium tax credits actually work, why a Roth conversion or a big capital gain can trigger a subsidy cliff, and how to plan the pre-Medicare bridge years on purpose.
The IRMAA bracket cliff, the two-year lookback that separates cause from effect, and the planning move that trips it by accident.
Long-term care is one of the largest, least-modeled risks in retirement planning — not because it's unlikely, but because it's uncomfortable to plan for.
Lean, Fat, Chubby, Coast, Barista — the FIRE movement's named variants explained honestly, and why the label matters less than your actual savings rate and spending target.
72(t)/SEPP, the Rule of 55, Roth conversion ladders, and why taxable brokerage usually does most of the real work.
Most people never decide between spending confidently and protecting an inheritance — they just under-spend out of fear, which answers it anyway.
For most retirees the home is the biggest asset — but the "profit" from selling isn't the sale price. The honest math on net proceeds, capital gains, and whether downsizing frees as much as you think.
Your friend's app says 95%. This one says 82%. Nobody's lying — the five quiet assumptions that move the number, and the questions to ask any tool before trusting its score.
"Max your 401k," "delay Social Security," "consider a Roth conversion" — all directionally right, all useless until weighed against your specific numbers.
A plan is a snapshot of assumptions at one moment. The market moves, spending shifts, goals drift — the trajectory across check-ins tells you more than any single number.
AI is good at explaining a retirement plan and unreliable at calculating one. How to tell the difference, and six questions to ask any AI retirement tool.
A simulation grades the plan you already have. A searched optimizer tries many different plans and tells you which one actually scored highest.
Life expectancy is the average — half of people that age outlive it. Why the SSA's own mortality table points to a longer, more honest planning horizon.
This Year’s Retirement Numbers
The new Social Security cost-of-living adjustment, contribution limits, Medicare and ACA figures, each with what it does to a plan.
We Tested All 81 Ways a Couple Can Claim Social Security
Original data: 486 simulations across six couples. The best strategy changed with the goal — legacy, income, or the survivor — which is why every tool disagrees.
Should I Claim Social Security at 62, 67, or 70?
Why the popular "breakeven age" framing misses the insurance value of a bigger check late in life — and how a spouse changes the math.
Lump Sum, or the Monthly Check for Life?
A genuine actuarial tradeoff, not free money vs. leaving money on the table — plus the single-life vs. joint-and-survivor decision that's easy to get permanently wrong.
The Paycheck for Life That Quietly Shrinks
Original data: three households, the same $6,000/mo guaranteed income and the same savings — and a 34-point gap in whether the money lasted. All of it from one line item nobody checks.
What a Widow or Widower Actually Needs to Know About Social Security
Survivor benefits aren't one fixed check — a real choice between two benefits, a reduction schedule starting at 60, and a claiming order that's often hard to undo.
