"Save for 10 years at 3.5% compound — way better than a bank deposit!" Sounds familiar? What you may not realize is that the agent's "3.5%" and the return you actually pocket are two different things. The real return on annuities and savings policies is measured by IRR (internal rate of return), and many products marketed as "3.5% compound" deliver an actual IRR of just over 2%. Today I'll teach you to read an annuity's true return in a minute.
Why the Agent's "3.5%" Can't Be Trusted: Compound ≠ IRR
The "3.5% compound" agents quote usually refers to the assumed interest rate or sum-assured growth rate, not the yield your actual invested money earns. The real measure is the cash value — the money you'd get back if you surrendered the policy.
IRR is the standard for real return: list every premium paid (cash outflow) and every cash value or benefit received (inflow) as a cash-flow stream, and the annualized rate it yields is your IRR. Example: pay 100,000 a year for 5 years, and the cash value at year 20 is 800,000 — the IRR may be only 2.5%, well below your hoped-for 3.5%. To compute it yourself, use the CAGR calculator and the compound interest calculator to back out the true annualized rate.
Cash Value and Break-Even Year: The Two Numbers to Check Before Buying
Cash value is "the money truly yours" in the policy, and in the early years it's usually far below the premiums you've paid — that's the surrender loss. Many annuities surrender in the first 5 years for only 30%-60% of principal, so liquidity is poor; only money you can lock away for 10+ years belongs here.
Break-even year is when the cash value exceeds cumulative premiums paid. Some products break even in year 8, others need 15. The later the break-even, the longer your money is "locked." Use the percentage calculator to see the surrender-loss ratio and grasp the policy's real liquidity.
| Product type | Marketing claim | Real IRR reference | Break-even years | Liquidity |
|---|---|---|---|---|
| Traditional annuity | ~3% compound | ~2.0%-2.5% | 8-15 years | Poor |
| Increasing whole life | 3.5% sum assured growth | ~2.8%-3.0% | 5-10 years | Medium |
| Participating policy | Illustrated high returns | Uncertain (depends on dividends) | Not fixed | Poor |
| Large bank CD | ~2% annualized | ~2.0% (simple) | Immediate / at maturity | Medium |
How to Judge Whether an Annuity Is Worth It: A Three-Step IRR Check
Step one: get the illustration table. Ask the agent for the cash-value table and note the cash value at each year.
Step two: lay out cash flows and compute IRR. Record premiums as negative and cash value as positive, then use the IRR formula for the true annualized rate. If the IRR is below the same-period Treasury or large CD rate, the policy isn't worth it.
Step three: compare alternatives. Use the compound interest calculator to project the same money in term deposits or Treasury bonds over 20 years and compare with the policy's IRR — in most cases, long-term bonds and index funds can beat an annuity locked for 10+ years.
One final reminder: annuities aren't a "scam." They're forced savings plus a long lock-up, suited to people with spare cash who can lock away 10+ years and strongly dislike volatility. But they're definitely not a "high-return investment." Before buying, compute the IRR and treat it as "deposit-like long-term savings," not "high-yield wealth management," so you won't be disappointed. To know a policy's true return, remember: don't trust the marketing, read the cash value; don't compute compound, compute IRR.
FAQ
Q1: Is the agent's "3.5% compound" a lie?
Not necessarily a lie, but it's usually the "assumed rate" or "sum-assured growth rate," not the return on your actual money. The true rate, computed from cash value and IRR, is often lower than the marketing figure.
Q2: What is cash value, and what's it for?
Cash value is what you'd receive on surrender, usually below premiums paid in the early years. It's the basis for computing IRR and the yardstick for surrender losses.
Q3: When can I surrender an annuity without losing money?
Generally after the cash value exceeds cumulative premiums (break-even). The break-even year appears in the product illustration — check it before buying.
Q4: Who is an annuity right for?
People with spare cash who can lock it away 10+ years, strongly dislike volatility, and want forced savings. If you seek high returns or need liquidity, an annuity isn't a good fit.
