Index Frontier 5 Plus review

Yes, for the right buyer — but with a clearer caveat than most indexed annuities require. This is a good annuity for someone who wants index-linked growth with a defined safety net and accepts that "defined safety net" is not the same as "no losses." It is a poor fit for anyone who assumed an annuity means their principal is guaranteed, because that is not how a RILA works.

The main reason to buy Index Frontier 5 Plus is accumulation with cushioned downside. A buyer here wants more growth potential than a fixed indexed annuity, where a bad year simply credits zero, and is willing to give up that full protection to get higher caps. The secondary reason is structural flexibility — the menu lets you choose how much risk you take, from a tight -10% floor that caps your worst-case loss to a 20% buffer that absorbs the first fifth of any decline. The short 5-year commitment is a third draw for people who do not want to lock money up for a decade.

I think Index Frontier 5 Plus is best for a financially comfortable accumulation buyer, often in the pre-retirement or early-retirement years, who already understands the difference between a buffer and a floor and is using qualified or non-qualified dollars they will not need for at least five years. It suits someone who finds fixed indexed annuity caps too restrictive but is not willing to take on the full downside of being in the market directly. It is not for conservative buyers who want guaranteed principal, for anyone who needs reliable access to the money, or for someone shopping primarily for lifetime income — there is no income rider here.

You are not buying principal protection, and you are not buying direct ownership of the index. You are buying a contract that gives you part of an index's gain, up to a limit, in exchange for absorbing part of an index's loss. The "buffer" and "floor" language can blur this, so it helps to be precise. A buffer absorbs losses up to a point and then hands the rest to you: a 10% buffer means the insurer eats the first 10% of a decline, but if the index falls 25%, you absorb the remaining 15%. A floor works the opposite way — the -10% floor means you absorb the first 10% of losses and the insurer covers anything beyond that, so your worst case is fixed at -10%. Either way, in a down market, you can end a term with less than you put in. That is the defining feature of a RILA, and it is the single most important thing to understand before signing.

Index Frontier 5 Plus credits interest based on the performance of an index over a term — most strategies use a one-year term, with two five-year strategies available only in the first contract year. You allocate your money among strategies, each pairing a protection level with an upside method. The protection level is either a -10% floor, a 10% buffer, or a 20% buffer. The upside method is either a cap, a performance trigger, or a dual performance trigger. A cap strategy credits the index gain up to a maximum. A performance trigger credits a flat declared rate if the index is flat or up, and nothing if it is down (within the protected band). A dual performance trigger goes a step further and can credit that flat rate even when the index is modestly down, as long as the decline stays inside the buffer. As of the December 7, 2025 rate sheet, the S&P 500 one-year strategy with a 10% buffer carried a 19% cap, the 20% buffer version a 11.5% cap, and the performance triggers ran 10.5% (10% buffer) and 8.5% (20% buffer). The five-year strategies offered much larger cumulative caps — 85% with the 10% buffer and 75% with the 20% buffer — but those are five-year figures, not annual, and are only available at issue. There is also a declared fixed-rate account, paying 3.80% on that same date. Rates are a snapshot and change at each term; the cap can be reset as low as 1% on renewal, which is a real risk worth asking about. The more protection you choose, the lower your cap or trigger — that is the central tradeoff inside the menu.

The most meaningful secondary feature is the Performance Lock available on select strategies. It lets you lock in the current value of a strategy partway through its term — capturing a gain before the term ends, or stopping further losses if the index has turned against you. The catch, which is easy to miss, is that once you lock, you give up any further movement for the rest of the term, up or down. Lock too early and you may leave gains on the table; lock too late and you may have already taken the loss. It is a useful tool for an engaged owner who watches the contract, but it is not a guarantee and it does not turn a RILA into a protected product. It is best thought of as a manual brake, not an autopilot.

You are trading five years of liquidity for the contract's structure. The surrender charge starts at 8% and steps down to 0% after year five. The free-withdrawal allowance is up to 10% per year — based on purchase payments in year one and on the prior anniversary's account value thereafter — with a $500 minimum withdrawal and a requirement that at least $5,000 stay in the contract. Importantly, the allowance does not carry over, so an unused year is simply lost. There is one mechanic specific to RILAs that matters here: taking money out of an indexed strategy before its term ends triggers a daily value adjustment, which the company warns can have a significant negative effect on that term's return. In other words, even a free withdrawal can hurt you if it pulls from a mid-term strategy. There is no market value adjustment on this contract, which is a point in its favor. The death benefit pays the greater of the account value or purchase payments adjusted proportionally for withdrawals. Two no-cost waivers add flexibility: an Extended Care Waiver that drops surrender charges after year one if you are confined to a nursing or long-term care facility for 90-plus consecutive days, and a Terminal Illness Waiver for a prognosis of 12 months or less after the first year — though neither is available in Massachusetts, and the extended-care version is structured differently in California. The spec did not confirm how required minimum distributions are treated, so if you are funding this with qualified money, ask the carrier directly whether RMDs are exempt from surrender charges.

On paper, the fee story is clean: there is no mortality and expense charge, no administrative charge, no product fee, and no annual contract fee. That is genuinely better than many variable and structured products. But "no fee" does not mean "no cost." The real cost of a RILA is embedded in the caps and triggers — the insurer funds the buffer or floor by limiting your upside, and the more protection you take, the lower your ceiling. A 19% cap on the 10% buffer is reasonable, but the 11.5% cap on the 20% buffer is the price of that deeper protection. The other structural tradeoffs are the loss exposure beyond the buffer or floor, the renewal risk that caps can reset lower at each term, and the daily value adjustment penalty for leaving a strategy early. None of these show up as a line-item fee, which is exactly why they are easy to overlook.
