The 0% floor and caps, explained

Why a down market does not cost you a credit, and why a great one is capped.

The short version
  • Down years credit 0%, not a loss.
  • Up years are limited by the cap and participation rate.
  • Caps can change. Ask for the guaranteed minimum.

Every crediting period, usually once a year, the insurer looks at how the index moved and credits your cash value using three rules.

The floor

If the index went down, your credit is 0%. You do not lose past credits to a bad year. Policy charges still come out, so your cash value can dip slightly in a flat year.¹

The cap

If the index went up a lot, your credit stops at the cap. With a 10% cap and a 15% index year, you would be credited 10%.

The participation rate

Some policies credit only a share of the gain. At 80% participation, an 8% index year credits 6.4%.

Ask your agent

What is the current cap, what is the guaranteed minimum cap, and can the insurer lower it later?

¹ Index-linked interest is never credited below 0%; policy charges still apply and can reduce cash value. Caps and participation rates limit upside. ² Policy loans accrue interest and reduce the death benefit and cash value if unpaid. Tax treatment depends on your situation.
