Compound Interest Is Real
$100 invested at 25 is worth more than $1,000 invested at 45. That is not a motivational poster — it is arithmetic. Compound interest means your returns earn returns, and the longer you wait, the more you lose.
The math: $200/month invested from age 25 to 65 at 7% average return = ~$525,000. Starting at 35 with the same amount = ~$243,000. Ten years of delay cuts the outcome in half. Start before you feel ready.
You do not need to understand the stock market to start investing. You need to understand three things: what a Roth IRA is, what an index fund is, and how to automate contributions.
The Broke Mode Investment StackIn This Order
- Employer 401k match firstIf your employer matches 401k contributions, contribute at least enough to get the full match. That is a 50–100% instant return. Nothing else competes with it.
- Open a Roth IRAA Roth IRA lets your money grow tax-free and withdrawals in retirement are tax-free. Open one at Fidelity or Vanguard — both are free. 2026 contribution limit: $7,000/year.
- Invest in a total market index fundVTI (Vanguard Total Stock Market ETF) or FSKAX (Fidelity Total Market Index Fund). One fund. Diversified across the entire US economy. Low fees. Set it and forget it.
- Automate monthly contributionsSet a recurring monthly transfer into your Roth IRA and auto-invest it. Even $25/month. The consistency matters more than the amount at the start.
- Increase contributions as income growsEvery time you get a raise, redirect half the increase to investments. You never adjusted to having it, so you won't miss it.
- Do not touch itThe Roth IRA early withdrawal penalty is 10% plus taxes. Leave it alone. Volatility is normal. Down years are normal. Time in the market beats timing the market.
What Not to Do
Do not buy individual stocks as a beginner. Index funds outperform most professional stock pickers over 10+ year periods. You are not the exception. Start with index funds.
Do not invest money you need in under 5 years. The market goes down. Sometimes a lot. Only invest money you won't need for at least 5 years, ideally 10+.
Do not wait until you have "enough" to start. $25 in a Roth IRA is better than $0. Fidelity has no account minimum. There is no entry fee for starting small.
Do not pay high expense ratios. Index fund fees should be under 0.10%. Check the expense ratio before you invest. Vanguard and Fidelity index funds are among the cheapest.
