For FIRE planners

FIRE without the spreadsheets.

If you've been hand-rolling savings rate, 4% rule, and Coast FI math in 14 tabs of Google Sheets, PeakWorth is what you've been trying to build. Real projections, real trade-offs, your real FI Age — recalculated every time you change a single input.

Sound familiar?

The problems other toolsdon't solve for FIRE Community.

Spreadsheets break at the edges

Coast FI, Barista FI, Lean vs Fat, sequence-of-returns risk, Roth conversion ladders — every new variable means another tab, another formula, another bug. You spend more time maintaining the model than living the plan.

Most planners assume you'll work to 65

The mass-market tools have hard-coded retirement at 65 and 'safe' return assumptions tuned for 401(k) defaults. If you're targeting 45 or 50, the standard math doesn't even apply.

It's hard to see what's actually working

Did increasing your savings rate 3% really matter? Was the house downsize worth it? Without a year-by-year projection that updates on every input change, you're flying blind on the decisions that decide the date.

Why PeakWorth

Built for how FIRE Communityactually think about money.

FI Age is a first-class metric

Not buried in a footnote. The exact age your investments cover your expenses is the headline number — and every input you change moves it in real time.

Models the full FIRE toolkit

Coast FI, Barista FI, Lean / Chubby / Fat targets, Roth conversion ladder modeling, brokerage-bridge years before age 59½, Social Security toggling on or off — all built in.

Year-by-year projection through 95

See the full glidepath: accumulation, the bridge years, traditional retirement age, RMDs. Adjust your return, inflation, and withdrawal-rate assumptions and the whole projection recomputes on your real numbers.

Year by year

Full projection from today through age 95 — no decade-buckets

Real-time

FI Age updates on every input change so trade-offs are visible instantly

Through age 95

Full lifetime simulation — accumulation, bridge years, retirement, RMDs

Frequently asked

Questions FIRE Community ask first

Does PeakWorth handle Coast FI and Barista FI?

Yes. You can model partial-income years, lower contribution years, and a bridge period of part-time work — and see how each scenario shifts your true FI Age.

Can I model Roth conversion ladders?

Yes. You can plan multi-year conversions, project the tax impact, and see how the ladder unlocks penalty-free brokerage withdrawals before age 59½.

Is this better than my custom spreadsheet?

If your spreadsheet already does dual income, year-by-year tax brackets, RSU vests, mortgage amortization, employer match vesting, and Social Security — keep it. Otherwise PeakWorth is doing in 2 minutes what most FIRE spreadsheets take 100 hours to half-build.
