Financial Independence is a Number
Why financial independence is about optionality, not reaching a specific age.
Financial independence is optionality
Financial independence means paid work becomes optional.
It is not really about hitting a conventional retirement age. It is about building enough assets that your lifestyle can be funded without needing a paycheck.
The two levers: expenses and assets
Financial independence becomes easier when either of these happen:
- Your expenses go down
- Your assets go up
Most people make progress through consistent, boring actions:
- Spend less than you earn
- Invest the difference
- Give compounding time to work
How to model it in Plan in Decades
The core question is simple:
When can my investments cover my expenses?
To model that well:
- Start from Wealth Tracking so your current position is realistic.
- Create a Scenario from your latest snapshot.
- Make sure your scenario includes realistic expenses, tax, and cash flow rules.
Where this shows up in the product
Your FI number and retirement timing are heavily influenced by:
- Spending assumptions
- Savings and contribution rates
- Investment returns
- Inflation
- Pension access and withdrawal timing
If you want the benchmark behind the number itself, read Your Retirement Number.
