Tool Reviewyoutube

Compound interest is the most powerful force in personal finance — and most people understand it in theory but not in numbers. In this video I break down simple vs compound interest, the early-vs-late comparison ($500/month at 7% starting at 25 vs 35 vs 45), the Rule of 72, the two things that silently destroy compound interest (fees and stopping), and how compound interest works against you in debt. 🎯 Timestamps: 0:00 — What is compound interest? 0:50 — Simple vs compound: the $45,000 difference 1:35 — The compound interest formula explained 2:15 — Starting at 25 vs 35 vs 45 — the $1M comparison 3:30 — The Rule of 72 4:20 — Where compound interest works FOR you 4:55 — The two compounding killers (fees + stopping) 5:35 — How debt compounds AGAINST you 6:10 — 3 action items starting today 📌 Key numbers: • $10K at 7% for 30 years: $76,123 (compound) vs $31,000 (simple) • $500/mo at 7%: Age 25 = $1,320,000 | Age 35 = $567,000 | Age 45 = $260,000 • Rule of 72: 72 ÷ 7% = 10 years to double | 72 ÷ 22% = 3.3 years (debt!) • 1% fee vs 0.03% fee on $100K over 30 yrs = ~$108,000 difference • $5,000 credit card at 22% + minimums = $8,000-$10,000 in interest Turn on DRIP (Dividend Reinvestment) in every brokerage account.
