See through insurance sales' "high-yield" pitches
Pitch 1: "Look, your money triples in a few decades!"
Salespeople love quoting absolute returns. CNY 500K becoming 1.5M sounds like a 1M gain — but across 30 to 50 years with inflation, tripling your money isn't impressive. Under IRR, many "3x" products compound at just 2.5%–3.0% a year.
Pitch 2: "A 3.0% guaranteed rate — very high!"
A 3.0% guaranteed rate ≠ 3.0% in your pocket.
The insurer first deducts operating costs and agent commissions; only the remainder compounds at 3.0%. That's why most policies show negative real returns for the first 5–10 years (surrendering early loses money). Only after 20+ years does IRR slowly approach 3.0%.
Simple vs Compound: The Magic Difference
Bank deposits pay simple interest (interest earns nothing), while insurance illustrations compound. Over long horizons (say 30 years), 3.0% compounded roughly equals 4.8% simple interest at a bank — that's why we show an "equivalent simple interest" figure for easy comparison with deposits.
