An annuity is an insurance contract that converts a lump sum into guaranteed income—essentially the opposite of life insurance. Fixed annuities guarantee a rate (typically 3-6%) with low risk. Present Value (PV) answers: what is a stream of future payments worth today? Formula: PV = PMT × [(1-(1+r)^-n)/r]. Future Value (FV) shows how much regular payments will grow.

Annuities are insurance contracts that convert a lump sum into guaranteed income — essentially the opposite of life insurance. The US annuity market is $380B+/yr. Fixed annuities guarantee a rate (3-6%), variable annuities invest in sub-accounts (higher potential, more risk), and indexed annuities track an index with a floor. Present Value of Annuity: PV = PMT × [(1-(1+r)^-n)/r]. Future Value: FV = PMT × [((1+r)^n - 1)/r]. Average annuity fees range from 1-3%/yr, which can significantly erode returns over time.

📋 Key Takeaways
- PV = PMT × [(1-(1+r)^-n)/r] — what future payments are worth today
- FV = PMT × [((1+r)^n - 1)/r] — how regular contributions grow
- Fixed (3-6%), Variable (market), Indexed (capped index)
- Annuity due pays at start of period → higher PV/FV than ordinary
- Surrender charges: 7-10% common in year 1, decline over 7-10 years
📊 Annuity Types
Fixed annuities guarantee a rate (3-6%) with low risk. Variable annuities invest in sub-accounts with higher growth potential but more risk. Indexed annuities track an index (e.g., S&P 500) with a floor—you participate in gains but have downside protection.
📐 Present Value Formula
PV = PMT × [(1-(1+r)^-n)/r]. Example: $1,000/month for 20 years at 6% annual (0.5%/mo) has PV ≈ $139,581. Higher discount rates reduce PV; longer terms increase it.
📈 Future Value Formula
FV = PMT × [((1+r)^n - 1)/r]. Example: $100K at 5% for 20 years grows to ~$265K. Used for accumulation-phase planning.
⏰ Annuity Due vs Ordinary
Ordinary annuity: payments at end of period. Annuity due: payments at start. Annuity due has higher PV and FV because each payment compounds one period longer. $500/mo for 30yr at 7%: Due ≈ $613K vs Ordinary ≈ $567K.
🚨 Surrender Charges
Penalties for early withdrawal, typically 7-10% in year 1, declining annually over 7-10 years. A 7% charge on $200K = $14K penalty. Many contracts allow 10% free withdrawals per year.
