Retirement timing
Can you retire before 59 1/2 without the penalty?
For: Single US professional age 55-56 with workplace retirement savings, deciding whether Rule of 55, a Roth ladder bridge, or 72(t) can support early retirement before age 59 1/2
Leaving work before 59 1/2 depends on verifying account access, health-bridge costs, and taxable cash before making an irreversible rollover.
Retire at 60: ACA, COBRA, spouse coverage, or HSA bridge?
For: US worker approaching 60 with employer health coverage, deciding whether ACA, COBRA, spouse coverage, HSA reserves, part-time work, or continued work can bridge to Medicare
Leaving work at 60 can be more about health insurance sequencing than portfolio size. Compare ACA, COBRA, spouse coverage, part-time work, and HSA reserves.
A realistic Bay Area Roth conversion ladder plan for a single high earner near the top of local tech compensation who wants to leave full-time work in the mid-40s without hand-waving health insurance, taxes, or local costs.
If you're a Bay Area saver near the top of local tech compensation, and especially if RSUs or existing taxable assets already give you a real head start, the Roth IRA / Roth conversion ladder can look like the final step between you and a mid-40s FIRE date. The catch is that the ladder still needs years of taxable liquidity, a realistic healthcare handoff, and enough spending discipline to keep the bridge from cracking.
This comparison starts with a mid-six-figure portfolio and assumes aggressive capital building before exit. It compares a ladder-heavy path, a taxable-first path that builds the biggest labeled bridge account, and a slower glide path with part-time income so you can see how the bridge pressure changes.
That framing matters because current FIRE interest around Roth IRA access can make the strategy sound simpler than it is. This is not a salary-only Bay Area FIRE case. The age-45 variants assume either already-vested taxable assets or unusually reliable equity liquidity on top of strong monthly saving. A saver limited to roughly $2,500-$8,500/month of ongoing savings would usually need a later exit, a lower retirement budget, or a larger starting bridge account.
If you already have a strong taxable cushion and don't mind the tax choreography, ladder-first can work. If you want the biggest margin against the five-year rule, taxable-first buys simplicity at the price of a much heavier savings push. If you expect a later exit or some part-time income, the hybrid path is the most forgiving way to keep healthcare and sequence risk from doing all the talking.
Across the three approaches, the table reports total modeled capital at the exit date, not taxable/cash balances by account. That distinction matters: ladder-first still works only if you separately verify a meaningful taxable runway, taxable-first buys the most flexibility but asks for the heaviest savings push, and hybrid gives you more room by delaying the exit and keeping some earned income in the first retirement years.
Where a version still ends with a sizable late-life cushion, treat that surplus as deliberate room for healthcare shocks, longevity, or planned giving rather than money the plan forgot to use. The preset does not assume a home sale or downsize equity release.
If you would rather avoid ending with that much cushion, use the preset to test lower pre-exit capital, higher planned spending, earlier giving, or fewer annuity-style late-life supports.

The pre-exit interest column understates how much compounding matters. In the base cases, cumulative interest by the end of the plan is roughly $2.27M for ladder-first, $2.57M for taxable-first, and $2.54M for hybrid. The bridge works only if the portfolio keeps compounding after the paycheck stops.
Can a conversion ladder carry Bay Area rent, ACA premiums, and recurring tax costs while you wait out the five-year rule?
Is it easier to build a larger taxable runway (and keep conversions smaller) even if that means a very heavy savings push for most of your 40s?
Would a softer exit—retiring at 47 with part-time consulting—buy enough buffer against healthcare spikes and sequence risk without abandoning the Roth strategy?
A Roth conversion ladder is not the same thing as immediate access to retirement money. In this kind of Bay Area plan, the first test is whether you can fund several years of spending from taxable cash, already-seasoned Roth money, part-time income, or another liquid source while conversions age. The second test is whether those conversions keep your tax bill and Marketplace income low enough that healthcare does not become the plan's hidden failure point.
That is why the table treats the account strategy as a bridge problem rather than a tax trick. Ladder-first is attractive only if the taxable runway is already credible. Taxable-first is simpler because more cash is available outside retirement accounts, but it asks for the largest pre-exit capital push. Hybrid reduces the pressure by delaying the exit and keeping some earned income during the years when healthcare and conversion timing are most fragile.
Pre-exit capital is not all paycheck saving. Ladder-first ramps hard in the early 40s. Taxable-first demands the biggest cash build and is most believable when equity compensation, prior taxable savings, or another real liquidity event is doing work alongside monthly saving. The hybrid path spreads the effort across a longer runway and uses part-time income to keep early withdrawals and ACA pressure lower.
Bridge capital still matters. All three paths include labeled bridge-account or taxable-account saving because the five-year seasoning rule is still real. The simulator reports one combined capital pool, so use the preset as a pressure test and then verify the actual taxable/cash balance outside this model.
Healthcare, taxes, and late-life income are planned rather than assumed away. Each path uses an explicit 18-month COBRA window, then income-sensitive Marketplace coverage, plus a modest annual tax-and-planning cost during the early conversion years. Later on, Social Security and a placeholder private-annuity assumption help test late-life cash flow, but actual annuity pricing needs quotes before you rely on it.
Lifestyle hits and giving goals show up in cash flow. Relocation costs, healthcare shocks, family support, later-life care, and in the optimistic versions large housing or giving goals are all included so you can see how much capital remains after those choices.
Best fit if you already have a credible taxable bridge and are comfortable managing a tighter five-year runway in bad markets. This is the pure conversion play: retire at 45 with $1.96M, keep retirement spending to $8,600/month below the safe line at $9,372/month, and let the annuity placeholder plus Social Security carry the late years so the plan still ends near $1.52M. The pessimistic variant remains cash-positive ($556k at age 90), but its minimum buffer falls to only about $11k around age 66; that is almost no room for error unless you trim withdrawals or stock a larger taxable reserve. Optimistic markets push safe spending to $11,643/month, and the scenario assumes you use most of that headroom by spending $11,600/month and making roughly $1.1M of family grants and community endowments, while still ending near $770k.
Best fit if RSUs or existing taxable assets already make a very large bridge realistic and you value simplicity over squeezing the earliest possible conversion plan. Here you keep a smaller workplace-retirement line while directing the real firepower toward taxable accounts (RSU liquidations plus the pre-FIRE cash hoard), so new capital added before exit averages $12,825/month. That leaves $2.24M at 45, keeps a $599k floor, and supports $9,450/month today vs. $10,304/month safe. Pessimistic returns still end with $590k and a $120k minimum buffer, so the path stays positive even if markets sputter, though you still need to verify how much of the combined capital is truly taxable. In stronger markets, this version can support materially higher spending and roughly $1.0M of one-time family transfers, but it still demands the heaviest pre-retirement liquidity load of the three paths.
Best fit if you want more margin than a clean age-45 exit provides. The hybrid path delays full retirement by two years and keeps some paid work in the early retirement phase, which lowers pressure on the portfolio while healthcare and conversion costs are still highest. It exits with $2.05M and keeps a $515k floor, so the safe line is $10,090/month versus $9,245 planned. The pessimistic version still clears $556k while keeping a minimum buffer near $50k because the consulting income and lower spending slow early withdrawals. Optimistic markets let you spend $13,145/month and fund roughly $1.2M of housing and community grants after resizing the giving package; the plan stays positive and finishes near $952k.
Replace the Social Security estimate with your SSA statement—your claiming age, income history, and any spousal benefits will change the safe line materially.
Decide how much taxable cash you need to sleep at night. If you want more than a multi-year bridge, increase the taxable saving, add a real liquidity event before you leave work, or plan on a later exit.
Adjust healthcare assumptions to your real plan: swap COBRA for immediate Covered California, add HSA drawdowns, or model high-deductible vs. gold-level premiums.
If you expect RSU cliffs, bonuses, or severance, time those cash-flow jumps to your real vesting and payout schedule instead of smoothing them into a straight line.
Hybrid-specific: update the part-time income line to whatever contract rate feels realistic, or delete it entirely if you intend a clean break from work.
Optimistic-only: resize or delete the philanthropic / housing-grant entries if you would rather boost your own late-life spending than fund community projects.
A Roth conversion ladder still obeys IRS Publication 590-B's five-year rule: every conversion has its own seasoning clock and is taxed as ordinary income, so resist the urge to treat Roth IRA or converted retirement money as instant cash once you quit.
Conversions raise income for Marketplace calculations. If you expect ACA help, test the plan with both subsidized and near-full-price premiums, because taxable withdrawals and consulting income can reduce how much help you receive.
California unemployment insurance tops out near $1,950/month, so it’s a partial buffer at best—don’t assume UI can bridge a multi-year ladder seasoning gap.
State taxes can matter on conversions, RSU sales, and taxable-account gains, so add state withholding or a quarterly estimated-tax line if you know your marginal rate will exceed the low-five-figures tax allowance used in the early ladder years.
Social Security estimates in this preset assume a near-max single earner who claims at full retirement age or later. Use the SSA calculator to plug in your actual earnings history; dropping high-income years can pull a high-earner estimate down from the rough $3k-$4.2k/month planning band.
Healthcare transitions are time-sensitive. If you plan to leave a job outside the usual COBRA or special-enrollment rhythm, move the health-cost transition so the plan matches when coverage really ends.
