Lesson
Investment Fees & Taxes
Summary
Every investment quietly takes a cut before gains land, through fund fees, trading costs, and taxes. This lesson unpacks how expense ratios and capital gains taxes can make or break long-term returns.
Bellringer: The $10,000 Disappearing Act
- Pose: two investors, same returns, very different ending balances — why?
- Quick pair-share on what could account for the gap.
Instruction
- Walk through expense ratios, capital gains, and dividend taxation.
- Use slide examples to anchor each concept.
Activity: Investment Calculator Scenarios
- Students model investments over 30 years at different fee levels using the Banzai Investment Calculator.
- Run two scenarios separately: a one-time $5,000 lump sum, then a recurring $100/month contribution.
- Compare outcomes across fee levels and discuss findings.
Discussion: Holding-Period Strategy
- Debrief calculator results — surface the biggest fee gap students found.
- Work through the 9-month holding scenario to show how patience converts short-term gains to long-term.
Wrap-Up & Assessment
- What's the difference between short-term and long-term capital gains taxes?
- Why does a 1% expense ratio matter over decades?
