Planning for Life's Twists and Turns

Life isn't static—so why is your plan?

Maybe you're thinking about switching jobs, starting a family, or moving to a new city. Or maybe you just want to explore whether selling your RSUs or renting instead of buying makes more sense.

Most FI tools assume a straight line: no surprises, no changes, no questions. That's not real life.

  • You're stuck with one rigid plan, even if your goals shift
  • You can't test major tradeoffs or play out alternatives
  • You're left guessing how decisions impact your FI date

Without scenario planning, you're either planning blindly—or not planning at all.

MOF lets you explore what-ifs — and still stay on track

MOF gives you the flexibility to model real-life decisions and see how they impact your FI plan.

Adjust income, expenses, and goals

Want to cut expenses by 10%? Model a one-time splurge? Test an income boost or pay cut? Just enter your assumptions and MOF recalculates your entire plan.

Instantly see the tradeoffs

Each change shows immediate updates to your FI date, recommended actions, and your fastest path forward. You'll always know what you're trading—and what you're gaining.

Stacked scenario planning

Life doesn't change one variable at a time. Combine multiple changes like:

  • Getting a raise and funding college
  • Taking a sabbatical and delaying FI
  • Paying for a wedding and switching jobs

MOF handles interdependencies and remembers your inputs—so you never need to rebuild your plan from scratch.

Scenario Planning in Action: Sarah's Career Decision

Sarah earns $120,000 and is on track for FI at age 49. She's offered a role at a startup: lower base salary ($95,000) but with $50,000 in RSUs vesting over 4 years. Should she take it?

Scenario A: Stay Put
  • Salary: $120,000
  • FI age: 49
  • Predictable, steady progress
Scenario B: Take the Startup Role
  • Base salary: $95,000 (FI pushed to age 51)
  • With RSU vesting: FI at age 48
  • Higher risk, but potentially faster path

Without running the numbers, the lower salary looks like a step backward. But MOF's scenario comparison reveals that the RSUs more than compensate — the startup role actually accelerates FI by a year. This is the kind of insight that's invisible without modeling both scenarios side by side.
