What are realistic cap and participation rates right now?

Mid-2026 carrier-published S&P 500 annual point-to-point rates cluster around: caps of roughly 8%–12.25% at 100% participation (e.g., Lincoln 8.5–12.25%, Nationwide ~8.5%), or uncapped designs at 55–60% participation (e.g., Pacific Life’s declared-participation accounts). Rates are declared by the carrier and change — treat any illustration using a cap above current declared rates with suspicion.

What does the 0% floor actually cost me?

The floor is real — in 2008 (-37%) a floored account credits 0% instead of losing a third of its value. The price of that floor is the cap: you trade away part of the up years to eliminate the down years. Whether that trade wins depends on sequence — floors are worth the most to people who can’t afford a crash year near retirement, which is precisely who buys these policies.

What about the policy charges the calculator calls "fees"?

IULs carry cost of insurance (rising with age, shrinking with a max-funded design’s smaller net amount at risk), premium loads, per-policy charges, and optional rider costs — commonly totaling in the neighborhood of 1–1.5% per year of cash value across the life of a well-designed accumulation policy, far more in a badly designed one. The slider lets you model any drag you want; your actual number comes from the carrier illustration’s expense pages, which we’ll walk you through line by line.

So does IUL beat the market?

On raw accumulation, no — an uncapped index fund in a bull market beats a capped account; nobody honest tells you otherwise. IUL’s case was never raw return: it’s floor-protected compounding plus tax-advantaged access (IRC §7702/§72(e)) plus a death benefit — evaluated after tax and after sequence risk. That’s why we publish this calculator next to the IUL vs 401(k) comparison instead of a "12% average" pitch.

The Column the Brochure Hides

What an IUL really earns.

Every IUL pitch shows the illustrated column. Almost none show what the same policy credits when you apply a real cap, a real participation rate, and real charges to real market history. We build these policies for a living — and we’d rather you see this page before the sales pitch than after the surrender schedule.

The optimism gap

If a pitch only shows you the right-hand number, the left-hand number is the question to ask. A well-designed policy is sold on the honest column — and still makes its case.

Carrier-Published, Mid-2026

What the rates actually are right now.

S&P 500 annual point-to-point crediting, as declared by the carriers. Rates change at carrier discretion — which is itself something your illustration should be stress-tested against.

Sourced from carrier-published rate material, May–July 2026. Declared rates are not guarantees and are reset by carriers. If an illustration you’ve been shown assumes crediting above these ranges, ask why.

Crediting assumptions are only one part of the decision. Before comparing illustrated values, use our life insurance carrier comparison framework to check financial strength, underwriting fit, guarantees, charges, complaint history, and licensing at the source.

Asked Constantly

The questions a brochure won’t answer.

No — the most common misunderstanding in the category. The cap is the ceiling on the index credit in an up year. Your actual credit each year is the index change, multiplied by the participation rate, limited by the cap, floored at 0% — and the policy’s charges come out regardless. A 10% cap does not mean 10% average returns; back-tested against real index history it means meaningfully less, which is exactly what the calculator above shows.
