What Happens to Principal in an Annuity?

An annuity is a contract between an individual and an insurance company, structured to provide a stream of payments, often for retirement income. In an annuity, “principal” refers to the initial investment or total contributions made into the contract.

Principal During the Accumulation Phase

During the accumulation phase, the principal within an annuity grows before income payments commence. The method of this growth depends on the specific type of annuity purchased. For a fixed annuity, the principal earns interest at a rate guaranteed by the insurance company. Variable annuities, in contrast, link the principal’s growth to the performance of underlying investment options, often called sub-accounts, which can include stocks, bonds, or mutual funds. This exposes the principal to market fluctuations, offering potential for higher returns but also carrying the risk of loss. Fixed indexed annuities credit interest based on the performance of a specific market index, like the S&P 500, but often include features such as a “cap” on gains or a “participation rate,” and typically offer some protection against market downturns.

Accessing the principal during this accumulation period is typically restricted and may incur penalties. Insurance companies commonly impose surrender charges if funds are withdrawn or the contract is terminated before a specified period. Many annuity contracts do allow for penalty-free withdrawals of a small percentage, often up to 10% of the contract value or premium, each year.

In addition to insurer-imposed surrender charges, the Internal Revenue Service (IRS) may levy a 10% early withdrawal penalty on the taxable portion of withdrawals made before the annuity owner reaches age 59½. The IRS views earnings as being withdrawn first, meaning that most or all of an early withdrawal may be subject to this penalty, alongside ordinary income tax.

Principal During the Payout Phase

Once an annuity owner chooses to “annuitize,” the accumulated principal and any earnings are converted into a steady stream of regular income payments. The annuitization process means the principal, as a singular accessible amount, is no longer available to the owner.

Each payment received during the payout phase consists of two components: a return of the principal invested and a portion of the accumulated earnings or interest. The principal is gradually depleted over the payout period. This structured return of principal is designed to ensure the income stream continues as planned.

The taxation of annuity payments is determined by an “exclusion ratio.” For non-qualified annuities, which are funded with after-tax dollars, the exclusion ratio helps calculate the portion of each payment that is considered a tax-free return of the initial principal. The remaining portion of the payment, representing earnings, is subject to ordinary income tax. Calculating the exclusion ratio involves dividing the net cost of the annuity (the principal paid) by the total expected return. Once the total principal has been returned through these tax-free portions of payments, all subsequent payments become fully taxable as ordinary income. For qualified annuities, which are typically funded with pre-tax dollars (e.g., from a 401(k) or IRA), the entire amount of each payment is generally taxed as ordinary income because no taxes were paid on the contributions initially.

Influences on Principal Value

The type of annuity directly impacts the principal’s growth potential and risk exposure. Fixed annuities generally offer stable, predictable growth with minimal risk to the principal, as the interest rate is guaranteed. Variable annuities, however, expose the principal to market risk, meaning its value can fluctuate based on the performance of the chosen investment sub-accounts, potentially leading to losses. Fixed indexed annuities aim to balance these, offering market-linked growth opportunities while often protecting the principal from market downturns.

Fees and charges are deducted from the annuity’s value, thereby reducing the principal. Common fees include administrative charges, which can be a flat annual fee or a percentage of the contract value. Mortality and expense (M&E) charges compensate the insurance company for guarantees, such as lifetime income or death benefits, and typically range from 0.5% to 2% of the contract value annually. Additionally, variable and indexed annuities may have underlying fund expense ratios, ranging from approximately 0.06% to 3% of the assets invested. Optional riders, which provide enhanced benefits like guaranteed income or death benefits, also incur annual costs, typically between 0.25% and 1.5% of the contract value.

Withdrawals directly reduce the principal balance, impacting its ability to generate future earnings. Taking withdrawals, especially early ones, can trigger surrender charges from the insurer, which can be substantial and reduce the amount received. Furthermore, withdrawals before age 59½ may incur a 10% federal tax penalty on the earnings portion, in addition to regular income taxes.

Death benefits, if included in the annuity contract, are calculated based on the principal. These benefits can be structured in several ways, such as returning the remaining account value, the total premiums paid minus withdrawals, or a guaranteed minimum amount. For example, some contracts guarantee a return of the original premium or a stepped-up value. The taxation of death benefits depends on whether the annuity was funded with pre-tax or after-tax dollars; earnings from non-qualified annuities are taxable to beneficiaries, while the entire death benefit from qualified annuities is generally taxable.
