The Index Card

Helaine Olen & Harold Pollack · 2016

A finance professor once proved that everything you truly need to know about money fits on a single 4x6 index card, and then a journalist helped him show why those plain-spoken rules beat the expensive, complicated advice the industry sells you. This is personal finance stripped to what actually works.

Why it’s on the shelf

Boils all sound personal finance down to ten simple rules that fit on an index card.

Three of the ideas you’ll keep

The Clif summary of The Index Card pulls out 7 insights. Here are the first three.

  1. Aim to save 10-20% of your income, and build the emergency fund first, even starting at 1% and ratcheting up beats waiting until it 'feels affordable.'
  2. Pay your credit card in full every month; carrying a balance at 15-25% interest quietly cancels out almost any investment gains you make elsewhere.
  3. Max out tax-advantaged accounts (401(k), IRA, Roth, 529) and never leave a free employer match on the table, it's an instant, guaranteed return.

The other 4 — and the full 11-minute summary — are in the app.
