Interest Payments and Cash Value Growth
When you pay interest on a permanent life insurance policy, the amount you pay is added to the policy's cash value, which then grows based on the policy's credited interest rate and any applicable bonuses.

Compound Interest Mechanism
Most permanent policies credit interest daily or monthly and compound it, so each period's earnings become part of the base for the next period's calculation, accelerating growth over time.
Policy Types and Rate Differences
Whole life policies usually offer a guaranteed minimum rate, while universal and indexed policies can credit higher rates tied to market performance, though they may also include caps or participation rates.
Impact of Fees and Charges
Administrative fees, cost‑of‑insurance charges, and surrender charges are deducted from the cash value before interest is applied, reducing the net growth you actually see.
Example Growth Comparison
| Policy Type | Typical Guaranteed Rate | Potential Additional Credits |
|---|---|---|
| Whole Life | 2‑4% | Dividends (non‑guaranteed) |
| Universal Life | 1‑3% | Interest based on market index |
| Indexed Universal Life | 1‑3% | Index‑linked caps and participation |
