    • Essential luxuries

Savings Priorities

  1. Establish a one-month emergency fund
  2. Pay off high-interest debt
  3. Increase emergency fund to 3-6 months
  4. Pay off medium-interest debt
  5. Short-term goals

Ally Bank currently has the best interest rate.

Ignoring investments, the order should be:

Savings Strategies

  • Use Ally
  • Open a new account for each goal
  • Only save for short-term (<5-year) goals
  • Contribute to accounts based on urgency


  • It's not hard
  • The only effective way to beat inflation
  • Should be done early and often

Funds vs Accounts

  • A fund is a collection of financial assets.
  • An account is what holds these funds.

I bought $300 of Vanguard Total Stock Market Index Funds and placed them in my Roth IRA account.

Dude. Nobody cares.

Example sentence:

Types of funds

  • Domestic stocks

Types of accounts

  • Money market
  • Certificate of deposit
  • IRA
  • 401k

  • "Tax-advantaged"
  • Capped annual contribution

Other limitations apply based on income, marriage status, tax exemptions, etc.
