Sense check and potential next steps? : 40M, family of 3, aiming to retire at 45. Current ~$1.28M invested. Does the SEPP + ACA plan hold up?

Situation

Age 40, spouse (earns ~$24K), son age 10. Household income is mostly mine (~$130-140K).

Goal: stop working at 45 or take on less stress work if I have to.

Expense: Approx 75 - 80K / year.

Assets (approx.) :

401k = $827K

Taxable brokerage = $182K

HSA (invested) = $105K. Total = 113K

Cash/CDs/HYSA = $130K

Roth IRA = $42K

Investable total = ~$1.28M

Not counted: a 529 with $65K, and percentage in few shared properties.

Current allocation:

401k: That's 90% stocks ( snp500, large cap, world markets etc) and 10% bonds.

Brokerage: voo, schg and vxus, plus some legacy single stocks. Plan is to fund minmium 200 - 250/ week for another 5 years if possible.

Roth: VOO, SCHG, SMH, VXUS, maxed each year.

Plan:

- At 45, start a 72(t) SEPP on the 401k to bridge to 59½.... this seems very risky due to time horizion till 60.

- Fill the rest of spending from the brokerage, the Roth (contributions only) and the HSA.

- Claim Social Security at 63

My own Monte Carlo (10,000 runs, simplified): at $75K/yr, about a 79% chance the money lasts to 95. Assumptions: 8.5% return on the 401k, 7% on liquid assets, 3% inflation.

Questions:

If you are in same situation or has passed through same scenario...

  1. Is a ~79% success rate over a 50-year horizon acceptable, or should I work 1-2 more years? Do you use guardrails or a variable spending rule?

  2. Would you size the SEPP smaller than my full spending need to stay in a better ACA subsidy tier, and fill the gap from Roth and brokerage?

3)SEPP vs a Roth conversion ladder for a 45-year-old. Am I missing a better bridge?

4)How do you handle family health insurance costs from 45 to 65, given the post-2025 subsidy cliff? what are the options for health care?

  1. Is 10% bonds plus $130K cash enough to protect against sequence risk in the first 5 years?

  2. For FIRE planning, is a 3.25-3.5% withdrawal rate the right benchmark for a 50-year retirement?

  3. What is the withdrawal % of portfolio are you considering or considered? Given it needs to work for 50 years from 45 to age 95..

Appreciate any input and feedback.
