Compare similar life situations, assumptions, and retirement tradeoffs.

Housing
Single at 35: buy alone or keep investing?
For: Single US professional (35), high-cost-city renter, deciding whether to buy alone, rent and invest, or delay buying
Buying alone can work only if the mortgage does not crowd out your emergency reserve and retirement saving; this scenario shows when renting stays stronger.
Divorced at 45: rebuild retirement or buy a smaller home?
For: Single US worker (45), newly divorced, renting after separation, deciding whether to rebuild retirement first, buy a smaller home soon, or pause the housing decision
After divorce at 45, buying stability can be reasonable, but this scenario shows why liquidity and retirement rebuilding usually need first claim on the next.
You have two kids, a Seattle-area cost base, and a household income that can support serious saving. The catch is that you only get that surplus by keeping two full-time careers running.
This scenario pack models a family starting in January 2026 at age 38 with $250,000 already invested (investable savings only; home equity is not included). It compares three paths:
Stay full-time: keep both careers full-time and keep saving hard.
Part-time now: one parent drops to part-time immediately.
Staged shift: stay full-time for a few more years, then reduce hours.
All variants target a Barista FIRE-style transition at age 55: you leave full-time work, but assume some ongoing part-time income until Social Security age.
How to read this table: we are only tracking invested savings that could fund future spending. Home equity, mortgage payoff, and college accounts sit outside this comparison.

What to take away: the part-time decision mostly shows up as a smaller liquid base at 55. In this model, that reduces the sustainable retirement budget by roughly $2,000/month between the "stay full-time" and "part-time now" base paths.
A compounding gut-check: even in the Base return assumption, the stay-full-time path earns about $499k of cumulative investment interest by age 55.
Several versions also finish with more than a decade of annual spending still in reserve. Treat that as a sign to model later-life care, helping adult children, travel, or housing changes more explicitly, not as proof that you should automatically plan to spend every extra dollar each month.
This comparison asks how much room each work choice leaves for long-term saving after normal family costs.
Instead of listing every bill, the saving rows stand in for what is left after housing, food, transport, and child-related costs. The three paths mainly differ in how much saving is realistic before age 55. We also keep a few lumpy expenses in view - summer camps, a car replacement, a major home systems project, a health shock, and later-life care - so the plan is not built on a perfectly smooth budget. After 55, each version assumes some part-time earnings until Social Security begins at 67.
This path is the simplest mechanically: you keep the higher savings rate while the kids are still expensive, and you buy the most margin for bad markets or healthcare surprises.
It tends to be the easiest version to defend when the children are still young, the mortgage still feels heavy, or the family depends on strong employer health coverage. If the main goal is to create as much future choice as possible before easing up, this path gives the broadest buffer.
This path buys time back immediately — but it is also the easiest one to undermine if the downshift triggers more costs than you expected.
It is most realistic when the children are older, the housing payment is already stable, and the part-time move does not blow up health coverage or future earning power. It is much more fragile if younger children still need paid care, if a move or school change is likely, or if the lower-hours role comes with expensive insurance gaps.
This is the "keep options open" version. You delay the lifestyle change long enough to build a bigger base, then reduce hours once your liquid cushion is stronger.
That often makes it the most resilient family compromise: you keep the stronger saving years while costs are highest, then cut back once the mortgage, childcare, or career situation feels less exposed. In the base comparison, it preserves about $1,000/month more retirement room than cutting back right away while still creating a path to fewer hours later on.
Start by changing four things: the part-time earnings you realistically expect, your Social Security estimate, the age when you want full-time work to end, and any college saving you plan to add. Those changes usually tell you faster than anything else whether the part-time version still feels comfortable.
When you open the preset, the fastest high-signal edits are:
Replace the part-time income with what you actually expect (and set it to $0 if you do not want to rely on it).
Change the Social Security line to match your estimates and claiming plan.
Adjust retirement age (55 vs 58 vs 60) and watch how much that changes the sustainable retirement budget.
If you expect college saving, add it explicitly (monthly or yearly) so you can see how much retirement room it absorbs.
Seattle costs are lumpy. In the real world, housing, childcare, and healthcare do not fall smoothly just because hours are reduced. If your plan is tight, model a stress case where costs stay high for longer.
Health coverage is the swing factor. If the part-time shift changes employer health coverage, the premium + out-of-pocket difference can be large enough to wipe out most of the "extra time" benefit.
Account mix matters. At this income level, serious retirement saving usually means using more than one account type, such as workplace plans, IRAs or HSAs, and taxable investing. The exact mix depends on your benefits, tax bracket, and whether one parent keeps full-time coverage.
Social Security is earnings-history dependent. Treat the $6,500/month couple-level line as a placeholder until you have SSA estimates.
This scenario is an educational model, not financial advice. It simplifies taxes, employer benefits, account rules, home equity, and family spending patterns so you can compare trade-offs and then verify the details with current tools and official guidance.
