What Are Guaranteed Investment Funds and How Do They Work?

A guaranteed investment fund is a variable annuity sold by an insurance company that lets your money grow in market-based subaccounts while a contractual rider promises you, or your beneficiaries, at least a specified minimum amount back. The market piece behaves like a mutual fund; the guarantee piece is insurance. You pay for both.

These contracts are regulated as insurance products by state insurance departments and as securities by the SEC, with FINRA overseeing the brokers who sell them. That dual status is why a prospectus is required before purchase, and why the fees and restrictions are more involved than a straight brokerage account.

How the Contract Is Built

You pay premiums into the contract, either as a lump sum or over time. The insurer invests that money in subaccounts you choose, which hold portfolios of stocks, bonds, or other assets. Your account value moves with the markets.

Layered on top is the insurance guarantee. Even if the subaccounts lose money, the insurer commits to paying at least a defined minimum under specific circumstances: reaching a maturity date, the contract holder’s death, or scheduled lifetime withdrawals, depending on which guarantee applies. The guarantee is not on-demand. If you cash out mid-contract because the market dropped, the floor generally does not apply.

The Four Guarantees You Can Buy

Minimum Accumulation at Maturity

A guaranteed minimum accumulation benefit protects your principal over a set holding period, typically ten years. At the end of that period, the insurer guarantees your account will be worth at least the premiums you paid, less any withdrawals. If the market has taken you higher, you keep the higher value. If it has taken you lower, the insurer makes up the shortfall.

Death Benefit

A guaranteed minimum death benefit pays your beneficiary the greater of the current account value or a guaranteed minimum, often equal to purchase payments minus prior withdrawals.1Investor.gov. Variable Annuities Your heirs will not receive less than what you put in, even if the portfolio lost value.

Step-Up or Reset

Many contracts let you lock in market gains by raising the guaranteed floor to match your current account value. Invest $100,000, watch it grow to $130,000, and a step-up resets the floor to $130,000. The trade-off is that electing a reset often restarts the maturity clock, extending the holding period by another ten years from the reset date. Step-ups can apply to the death benefit, the accumulation benefit, or both, and some contracts allow them annually.

Lifetime Withdrawal Income

A guaranteed lifetime withdrawal benefit (GLWB) is an optional rider, priced separately, that lets you take a fixed annual withdrawal for the rest of your life. The withdrawal continues at the promised rate even if your account value falls to zero from market losses or prior draws. The rider turns the annuity into a source of guaranteed income without forcing you to annuitize.

What the Guarantee Costs

Annual costs on a variable annuity with a guarantee rider typically run 2% to 4% of account value, depending on which riders you select. These are deducted from your account, so they reduce returns every year the contract is in force.

The charges fall into four layers:

  • Mortality and expense (M&E) risk charge, which compensates the insurer for insurance risks including the death benefit and is assessed daily against subaccount values.
  • Administrative fees, either a flat annual amount or a percentage of the account, covering recordkeeping.
  • Subaccount management fees, comparable to a mutual fund expense ratio on the underlying portfolios.
  • Rider fees for optional features like a GLWB or enhanced death benefit, often 0.5% to 1.0% of the benefit base per rider.

Over long holding periods those percentages compound. A contract with a 3% total annual fee will produce meaningfully lower net returns than a low-cost index fund. The guarantee is real, and so is the price you pay for it every year the market rises.

Getting Your Money Out Early

Withdrawals during the early years of the contract trigger a surrender charge. Schedules commonly run six to eight years, starting around 7% in year one and stepping down about a percentage point each year until they reach zero.2Investor.gov. Surrender Charge A typical schedule looks like this:

  • Year 1: 7%
  • Year 2: 6%
  • Year 3: 5%
  • Year 4: 4%
  • Year 5: 3%
  • Year 6: 2%
  • Year 7: 1%
  • Year 8 and beyond: 0%

Many contracts include a free withdrawal provision letting you take up to 10% of account value each year without a surrender charge, with the fee applying only to the excess. Not every contract has this feature, so verify it in the prospectus.

The surrender charge is separate from the IRS penalty on early withdrawals. You can owe both if you pull money out before the surrender period ends and before you turn 59½.

Tax Treatment

Earnings inside the contract grow tax-deferred. You owe no federal income tax on gains, dividends, or interest until you actually withdraw money.3Internal Revenue Service. Publication 575 (2025), Pension and Annuity Income

Withdrawals from a nonqualified annuity, meaning one bought with after-tax dollars outside a retirement account, come out on a last-in, first-out basis: earnings first, then original principal. That means your first dollars out are fully taxable as ordinary income until the gains are exhausted, and only later withdrawals come from your untaxed principal.3Internal Revenue Service. Publication 575 (2025), Pension and Annuity Income That ordering is less favorable than a taxable brokerage account, where you can choose which lots to sell.

Withdrawing taxable amounts before age 59½ adds a 10% additional tax on the taxable portion, on top of regular income tax.4Office of the Law Revision Counsel. 26 U.S. Code 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts Exceptions include distributions after the contract holder’s death, distributions due to disability, and a series of substantially equal periodic payments over your life expectancy.

Death benefits from a variable annuity are not tax-free the way life insurance proceeds are. The portion of a variable annuity death benefit that exceeds the contract holder’s original investment is taxable as ordinary income to the beneficiary, and any interest earned between the date of death and the payout date is also taxable. Life insurance proceeds paid because of the insured’s death are generally not included in the beneficiary’s gross income,5Internal Revenue Service. Life Insurance and Disability Insurance Proceeds but that treatment does not carry over to annuity death benefits.

If the Insurance Company Fails

The guarantee is a promise from the insurer. Its strength depends on the insurer’s ability to pay. Every state runs a life and health insurance guaranty association that steps in when a member insurer becomes insolvent, covering annuity contract holders up to state-specific limits. The most common annuity limit is $250,000 per contract holder per insurer, with a handful of states, including Connecticut, New York, Utah, and Washington, going up to $500,000.6NOLHGA. How Youre Protected Contract value above your state’s cap may not be fully covered in an insolvency.

Guaranty association coverage is a backstop, not a substitute for buying from a financially strong insurer. Check the issuer’s ratings from independent agencies before signing.

Buying One

You purchase through a licensed financial professional, typically a broker-dealer registered with FINRA or a state-licensed insurance agent. Before recommending a deferred variable annuity, the broker must make reasonable efforts under FINRA Rule 2330 to determine your age, annual income, investment experience, investment objectives, time horizon, existing assets, and risk tolerance, and must have a reasonable belief you’ve been informed about surrender charges, tax penalties, fees, and market risk.7FINRA.org. 2021 Report on FINRAs Examination and Risk Monitoring Program – Variable Annuities Regulation Best Interest also requires the broker to act in your best interest. A recommendation made without any of that inquiry is a violation you can report to FINRA.

During the application you pick your subaccounts, choose your riders, name a beneficiary, and select a guarantee level. Some contracts offer a base guarantee, such as 75% of premiums at maturity, and a higher 100% guarantee for an additional fee. The prospectus filed with the SEC is your primary source for what the contract actually promises; read it before signing. Most states also require a free-look period of at least 10 days after delivery, during which you can cancel the contract for a full refund.
