Compound interest

Understand compound interest — why time on the market beats market timing, and how small early contributions outgrow big late ones.

Compare Roth IRAs and 401ks — tax treatment, contribution limits, employer match, and the rule of thumb on which to fund first.

Learn the difference between APR and APY — how compounding changes the real rate you earn or pay, and when each is quoted.

Understand index funds — why they beat most active managers over decades, how fees compound against you, and how to pick one.

Decide whether to pay off your mortgage early — the math of interest saved versus market returns and liquidity.

Compare stocks, gold, and Bitcoin as long-term stores of value — historical returns, volatility, and the role each plays in a portfolio.

Understand what actually moves your credit score — utilization, history, mix, hard inquiries, and how fast each one changes.

Use credit-card rewards without losing money — pick the right card, avoid interest, and track points without overspending.

Decide whether to refinance — when the rate drop justifies closing costs, and how to think about resetting the loan clock.

Read your payslip line by line — gross, net, withholdings, retirement contributions, and where each dollar actually goes.
