Inputs

Set the cash stack.

First-screen core inputs stay to eight. Acquisition and component detail are separate, optional layers.

Bounded to 1-30 years.

Defaults to today's dollars.

Maintenance mode

Editable CFPB worksheet placeholder, not a property-specific estimate. Named component costs are not added in Quick mode.

Optional cash to enter

Displayed separately; never counted as spent.

Modeled result

Home cash requirement, not an economic-cost claim.

Current monthly bills - Mortgage P&I plus current non-mortgage bills, at these assumptions.
Costs above mortgage over 10 years - Recurring owner costs and, in Detailed mode, the replacement wave.
Modeled 10-year cash requirement after closing - Includes mortgage cash outflow and costs above mortgage.
Cash to enter range - CFPB closing-cost range plus optional user-entered acquisition cash.
Near-term replacement exposure - Detailed-mode components scheduled in year 0 or 1.
Horizon-smoothed replacement equivalent - Comparison lens only; replacement bills do not arrive smoothly.

The mortgage payment is only one line in this modeled home cash stack. At these assumptions, taxes, insurance, utilities, upkeep, and major replacements add $0 over 10 years. Replacement bills do not arrive smoothly; the monthly equivalent is only a comparison lens.

Disclosures

  • At these assumptions.
  • Educational modeling, not buying, borrowing, insurance, tax, or investment advice.
  • Planning lives are editable triggers, not predicted failure dates.
  • Local quotes and property condition can differ materially.
  • Mortgage principal is included in cash outflow but is not labeled as an economic cost.
  • Source status: user-entered dollar inputs; CFPB-derived Quick placeholder and closing-cost range; planning triggers from source rows in the drawer.
  • Dollar status: today's dollars when owner-cost growth is 0.0%; future dollars when the growth assumption is above 0.0%.

    Direct answer

    Taxes, insurance, upkeep, and replacements can keep spending after closing.

    This calculator keeps the Down Payment Calculator narrow and prices the owner-cost stack separately. Quick mode uses an editable 1% maintenance rule of thumb; Detailed mode replaces that placeholder with user-entered routine upkeep and component quotes.

    How to read it

    Quick is a placeholder. Detailed is a plan you fill in.

    Quick mode uses a visible maintenance rule of thumb. Detailed mode asks for routine upkeep and local estimates or quotes, then shows the timing separately from the monthly equivalent.

    • No street-address lookup, lender API, insurance quote, contractor marketplace, account, save, or capture form is included in v1.
    • Replacement costs are blank until you enter them.
    • The Future Home hub keeps the saved Tracker as a separate tool.
    • The calculators hub lists every Aspire calculator.
