Reference implementation

What a white-label build on the component kit looks like: the same fictional household as /demo, but interactive — switch the theme (the sample brand override goes through the same config-time WCAG AA gate every tenant theme faces) and toggle between a consumer-lite view and the full advisor view. Every pixel inside the frame below is drawn by kit components from theme tokens; the engines run server-side.

The Rivera household is fictional, and the assumptions are labeled illustrative defaults — not a market view, not a recommendation, not advice.

The Rivera household (fictional)

Projected net worth ends at $3.8M on the deterministic path; 82.7% of 1,000 simulations stay funded over the fixed horizon, 89.9% when simulated lifespans are accounted for.

What this ranking does and does not consider (16)
  • ending net worth: $3,826,574; lifetime tax: $756,034
  • estimated IRMAA surcharges: $5,846 across 56 enrollee-years (max tier 1); score = ending net worth − surcharges; IRMAA delta vs baseline: $-12,665
  • ending net worth: $3,789,518; lifetime tax: $844,256
  • estimated IRMAA surcharges: $18,511 across 56 enrollee-years (max tier 2); score = ending net worth − surcharges; IRMAA delta vs baseline: $0
  • IRMAA estimate (v0.2): CY2026 Part B thresholds and premiums (cms.partb-premium-irmaa.2026) held constant across the horizon — future brackets are unpublished and MAGI thresholds index annually; MAGI proxied from projection rows (gross income + RMD + conversion) with the SSA two-year lookback; surcharges are NOT fed back into the projection's cash flows; 2 Medicare-age years skipped (two-year lookback precedes the horizon)
  • candidate schedules are caller-specified; bracket-fill optimization is not yet modeled
  • projection: RMDs computed per owner at each owner's age (Uniform Lifetime Table)
  • projection: deficits draw cash → taxable → traditional → roth; the draw is grossed up for the tax it creates, solved in the same year
  • projection: realized gains on taxable draws are treated as long-term (holding period not tracked) and taxed in the year they are realized
  • projection: social_security streams with a computed-benefit block use the ssa-pia model, indexed from the claim year at the COLA assumption; the benefit itself is computed from eligibility-year bend points, which are not wage-indexed forward
  • projection: state tax treats realized gains as ordinary income (no state preferential rates modeled)
  • projection: state taxable income approximated by federal taxable income
  • ending net worth: $3,580,635; lifetime tax: $713,582

Pension election

Objective: maximize the actuarial expected present value of the pension election at the caller's discount rate (scores in USD EPV; mortality from the NCHS 2024 period table)

Baseline: the plan's single-life quote — every option priced on the same lives and rate

    −$13K vs baseline
    • Commence the joint & 50% survivor annuity of $2,050/mo at age 65 (in 2027).
What this ranking does and does not consider (13)
  • expected present value: $420,000
  • delta vs single-life: $79,630 (EPV, not a projected net-worth path)
  • expected present value: $340,370
  • delta vs single-life: $0 (EPV, not a projected net-worth path)
  • EPVs at a 5% caller-supplied discount rate, valued at 2027 (participant age 65); payments annual, survival measured at year start
  • mortality from the NCHS 2024 PERIOD life table (nchs.us-life-table.2024): it understates future longevity improvement, which systematically understates annuity EPVs relative to the lump sum
  • pre-tax comparison: annuity income taxation vs lump-sum rollover treatment is not modeled
  • joint-survivor EPVs assume the two lives are independent
  • lump sums are conditioned on the participant surviving to commencement; pre-commencement death benefits are not modeled

What this ranking does and does not consider (17)
  • ending net worth: $3,863,717
  • ending net worth: $3,789,518

  • pension elections are handled by the pension-election strategy, which prices options on the NCHS mortality table
  • projection: RMDs computed per owner at each owner's age (Uniform Lifetime Table)
  • projection: deficits draw cash → taxable → traditional → roth; the draw is grossed up for the tax it creates, solved in the same year

Embed these widgets anywhere

The same surfaces are embeddable on any site — no React required — with the same loader that serves the calculator embeds:

<div data-worthune-embed="household-overview" data-theme="dark"></div>
<script async src="https://worthune.com/embed.js"></script>

Or as custom elements, if your stack prefers components — same frames, reactive attributes:

<script async src="https://worthune.com/elements.js"></script>
<worthune-household widget="monte-carlo" theme="dark"></worthune-household>
<worthune-calculator model="fire" input-current-age="35"></worthune-calculator>

Widgets: household-overview, household-projection, household-monte-carlo, household-decisions. Frames size themselves to their content. Without a token, embeds show the seeded fictional household; Growth-tier tenants bind them to real households with signed tokens (data-token) restricted to their domain allowlist — see the API docs for /api/v1/tenant-config and /api/v1/embed-tokens.
