Household planning
Coast FIRE for couples
Plan Coast FIRE for two people using shared spending, separate retirement dates, account ownership, benefits, and survivor scenarios.
Couples do not need two independent Coast FIRE numbers if they fund one shared household. They need a household target that respects different ages, account ownership, benefit dates, and what happens when one income or one person is gone.
Start with shared spending, then model each partner’s timeline rather than averaging ages and hoping the difference disappears.
A five-step couples workflow
- Build one retirement budget and identify costs that will not fall by half for a survivor.
- List accounts by owner, tax type, and earliest practical access date.
- Calculate the household FIRE target from the portfolio-funded spending gap.
- Discount the target across each relevant time horizon rather than using an average age.
- Run one-partner-working, both-coasting, and survivor scenarios.
Do not average away important differences
Ages, health coverage, pensions, and Social Security claiming dates can differ. An average age may be acceptable for a rough sketch but can hide a long coverage bridge or an account-access problem.
Questions to answer before either partner cuts back
- Whose employment supplies health insurance?
- Can either partner return to full-time work if the plan underperforms?
- How are unpaid care, chores, and free time expected to change?
- What spending remains if one partner dies?
Frequently asked questions
- Should couples combine retirement accounts?
- The planning view can combine balances, but legal ownership and tax treatment remain account-specific. Preserve those distinctions in implementation.
- Can one partner Coast FIRE while the other keeps saving?
- Yes. Model each contribution stream and the shared target explicitly rather than applying one label to both people.
- Should couples use joint spending?
- Usually yes for the household target, with separate timing for benefits, account access, and survivor adjustments.
