Personal financial model

A personal financial model is a structured representation of your income, expenses, assets, liabilities, and future assumptions over time.

  • It is broader than a monthly budget.
  • It connects cash flow with balance-sheet changes.
  • It is used to compare decisions before they happen.

Definition

A personal financial model is a forward-looking plan that maps how your financial life changes over time. It typically includes earnings, expenses, savings, investments, debt, and important timing assumptions such as retirement or large purchases.

Why it matters

Without a model, decisions stay isolated. With a model, you can see how one decision changes the rest of the plan, especially across many years.
