Financial Literacy¶
Overview¶
Financial literacy for engineers means budgeting with variable equity, understanding taxes at a high level, saving for goals, and avoiding common behavioral traps—not day-trading memes.
Why This Exists¶
Compensation complexity increases with seniority; basic literacy reduces stress and supports long-term decisions.
How It Works¶
Topics: budgeting, emergency funds, retirement accounts (locale-specific), diversification, fees, inflation, and risk tolerance. Separate investing education from career decisions.

Key Concepts¶
Personal finance is personal
Optimize for sleep-at-night money first—aggressive investing before an emergency fund is fragile.
Code Examples¶
Fixed costs: rent, utilities, insurance
Variable: food, travel, hobbies
Savings rate target: X% of net
Retirement: automate contributions
Interview Questions¶
Why diversify instead of picking stocks?
Reduces idiosyncratic risk; most individuals lack persistent edge—index funds are a common baseline.
What is lifestyle inflation?
Spending rises with income, eroding savings rate—watch it after promotions.
Practice Problems¶
- Track spending for a month and categorize surprises
- Read your pay stub and list pretax vs posttax deductions
