Monte Carlo simulation

Planned

Real probability ranges around your Optional Date, using thousands of return sequences instead of a single deterministic 7% path.

Partner planning

Planned

Model a joint plan — two incomes, two savings rates, one household spending target. Shared Optional Date, per-partner account visibility, and combined Scenarios Lab.

Social Security modeling

Proposed

Add expected Social Security income by claim age and see how it changes your Optional Number and post-Optional runway.

Tax-aware withdrawal order

Proposed

Model taxable/tax-deferred/Roth withdrawal strategy in Life after Optional, including required minimum distributions.

Native mobile app

Proposed

iOS and Android apps that reuse the same engine, with quick balance updates and reminders.

Export scenarios as PDF

Proposed

Save a snapshot of any saved scenario as a PDF, useful for sharing with a partner or financial planner.

Monthly reminder to update balances

Proposed

Optional email nudge to keep your numbers fresh — off by default, opt-in per user.
