Why Appleseed Treats Housing and Healthcare Separately

The two costs in your life that change by decision, not by inflation—and why the engine estimates them for you instead of asking you to guess.

The short version

Most of your expenses drift—they rise smoothly with inflation, and a single number captures them well. Two don’t. They jump: housing when you move, healthcare when you retire before 65—and again when Medicare starts.

That’s why you enter your monthly expenses without housing and healthcare: Appleseed estimates those on its own and adds them to your plan. If your plan looks tighter than you expected, this is usually why—the engine is carrying costs most calculators quietly ignore.

01
Drift vs. Jump

Most expenses drift. These two jump.

Groceries, travel, the general cost of being you—they rise smoothly, year after year, and one clean number describes them for decades. Housing jumps when you move. Healthcare jumps when you retire before 65, and jumps again when Medicare starts. Those steps are decisions, not inflation—so the engine models them where decisions can move them.

What you enter

Your monthly expenses, minus housing and healthcare. One clean number for the part of your life that drifts.

What the engine carries

Mortgage or rent, property tax, insurance, maintenance, and health premiums—estimated automatically and added to the plan.

02
The Pre-Medicare Bridge

The healthcare gap most planners skip.

Retire at 55 and your employer coverage ends. Medicare starts at 65. In between sits a ten-year stretch where you’re buying private insurance—often the single most expensive decade of healthcare in your life, landing exactly when your paycheck stops. Most tools either ask you to guess that number or silently fold it into “expenses.”

Appleseed models the sequence automatically. Move your retirement age from 65 to 55 and watch the plan absorb ten years of bridge coverage—no manual math, no silent gap where your most expensive decade should be.

The bridge is priced from published marketplace data, not a national average: the benchmark premium in your state, scaled to your age by the federal ACA rating table, at Bronze, Silver or Gold. Then the plan estimates subsidies using the previous year's projected income. We assume no subsidy in the first year of the projection because that income is unavailable. The state is your primary home's state each year, so a move to another state reprices coverage from the move year. You can choose who is covered and adjust the plan level on the Healthcare page.

While you’re working

Employer-subsidized costs—the modest share you actually pay under group coverage.

From retirement to 65

The marketplace bridge: your state’s benchmark premium, priced at your age under the federal ACA age table, at the plan level your assets suggest. Subsidies use prior-year projected income, with none assumed in the first projection year. Costs grow with healthcare inflation.

From 65 on

The switch to Medicare, with premiums that follow their own trajectory for the rest of the plan.

03
Housing in One Click

A home move is a system, not a line item.

Elsewhere, modeling an upgrade means estimating—yourself—the new property tax, the new insurance premium, the new maintenance, and how each inflates over the following decades. Most people have no idea how to estimate any of that. So they don’t, and the scenario is quietly wrong.

In Appleseed it’s one click. Ask the solver, and the engine derives the carrying costs that come with the house—then inflates each at its own rate, because property tax and homeowners insurance don’t grow like groceries do.

As many moves as your life

Downsize in retirement? Another click. Move twice? Your plan holds every home and every transition.

04
The Payoff

Separating the jumps keeps the rest of your plan simple.

Your monthly-expenses number stays clean because it only has to describe the part of your life that drifts. The lumpy, decision-driven costs live where the engine can move them when you try a different decision—and trying different decisions is the entire point. Retire at 55 instead of 62. Upgrade now, downsize later. Take the package or don’t.
