Market value adjustments: why your annuity value can move on exit

A market value adjustment, usually called an MVA, is a contract provision that changes the amount you receive when you leave a fixed annuity early, up or down, depending on what interest rates have done since you bought. If rates have risen, the adjustment generally lowers your payout. If rates have fallen, it generally raises it. It applies to certain exits, not to every withdrawal, and the formula is written in the contract.

This post explains the idea behind the adjustment, works through one example with the arithmetic, and lists where to look in your own paperwork. The numbers are invented for illustration and are not rates, quotes or any company's formula. The short entry in the glossary on market value adjustment gives the definition, and the guide on annuity surrender charges and free withdrawals places the MVA next to the other costs of leaving early.

Why a fixed annuity's value would depend on interest rates at all

When you give an insurer money for a fixed annuity or a multi-year guaranteed annuity, it does not leave the cash in a drawer. It generally invests it in bonds and similar assets that pay interest over a set number of years, aiming to earn enough to credit your guaranteed rate and cover its costs. The guide on how annuity rates are set and why they move describes the process.

Bonds have a feature that matters here. A bond that pays 4% is a good deal when new bonds pay 3%, so someone would pay more than face value for it. When new bonds pay 5%, the same 4% bond is less attractive and sells for less. Prices move in the opposite direction from rates.

Now suppose many contract holders want out at the same moment, rates have risen, and the insurer has to sell bonds to pay them. It would sell at a loss. An MVA passes that loss, or gain, to the person who leaves, instead of spreading it across everyone who stays. Supporters argue that this makes it fair to remaining owners and lets the insurer offer a better crediting rate than it could if exits cost it money. Critics point out that the adjustment makes the exit value harder to predict and harder to compare between contracts. Both views have merit, and the provision is a trade-off, not a trick.

The direction of the adjustment

The relationship is simple to state, even if the formula is not:

Two points deserve emphasis. First, the adjustment is two-way in most contracts, so a falling-rate environment can give you more than your account value. Second, the adjustment is typically limited by a floor: the contract guarantees a minimum value, so the MVA cannot push you below it. The size of that floor, and how it is calculated, differs from contract to contract. The post on the minimum guaranteed value in a fixed annuity: what the floor protects looks at the floor itself.

The adjustment in one worked example

Contracts use different formulas, and yours may differ in detail. A common structure compares a reference interest rate when you bought the contract with the same kind of rate when you leave, and applies the difference to the time remaining in the guarantee period. A simplified version looks like this:

Adjustment factor = (1 + rate at purchase) ÷ (1 + rate at exit), raised to the number of years remaining.

Many real formulas add a small constant to the exit rate, and some work in months or use different reference rates. Treat this as a teaching version.

Say a hypothetical owner buys a seven-year multi-year guaranteed annuity with $100,000 at a guaranteed 4%. The reference rate at purchase is 4%. After four years, there are three years left in the guarantee period, and the account value is:

$100,000 × 1.04⁴ = about $116,986

The owner wants to surrender the contract. The contract allows 10% of the account value free of surrender charge and charges 5% in this contract year on the rest. It applies the MVA to the amount above the free amount.

• Free amount: 10% × $116,986 = about $11,699
• Amount subject to the charge and the MVA: $116,986 − $11,699 = about $105,287
• Surrender charge: 5% × $105,287 = about $5,264

Now three cases for the reference rate at exit:

The same contract, on the same day, produces three different checks depending only on rates. The spread between the first and last rows is about $6,076, which is the sum of the downside and upside adjustments. That is the size of the rate sensitivity for a three-year remaining term and a rate move of one point either way.

Also notice what drives the size. The longer the time remaining, the larger the adjustment, because the factor is raised to a power. With only one year left, a one-point rate move would change the amount by about 1%, not about 3%. A bigger rate move and a larger balance both increase the adjustment. And when the guarantee period is nearly over, the adjustment shrinks toward zero.

In the example, the order is simple: charge first, then adjustment. In some contracts the adjustment is applied first and the charge is calculated on the adjusted amount. Others use the MVA in place of a surrender charge in later years. The contract states the order.

Which exits the adjustment applies to

An MVA does not hit every dollar you take out. In many contracts, it applies to:

• A full surrender during the guarantee or surrender period.
• A withdrawal above the free amount during that period.
• A transfer out, in some cases, such as a partial exchange.

It often does not apply to:

• The free withdrawal amount, which is paid without a charge or adjustment.
• A death benefit, in many contracts, though you must read the death benefit provision to be sure.
• Money taken at the end of the guarantee period, such as during the window after a multi-year guarantee matures. The post on your multi-year guaranteed annuity is maturing: the choices ahead describes that window.
• Annuitization after a stated period, which in some contracts is exempt and in others is not.
• Certain waiver events, such as nursing home confinement or terminal illness, in contracts that include those waivers.

This is a pattern, not a rule. Exemptions are contract language, and two contracts from the same company can differ.

Where the MVA lives in your paperwork

An MVA is rarely hidden, but it is rarely prominent. Look for these:

1. The contract data pages, which may list the "MVA index" or "reference rate," the term over which it applies and any constants in the formula.
2. An endorsement or rider titled "Market Value Adjustment." This contains the formula and often a worked example.
3. The withdrawal or surrender provision, which says which events trigger the adjustment.
4. The guaranteed minimum value provision, which sets the floor.
5. The disclosure or buyer's guide given at application, which may describe the MVA in plain terms but is not the final authority.

If the contract has an MVA, the insurer's statement will normally show the surrender value, which may or may not already include a current estimate of the adjustment. Ask which. A value that includes the estimate is the one to use for decisions, and one that excludes it can be too high or too low.

How time remaining scales the effect

The worked example used three years left. Because the factor is raised to the number of years remaining, the same one-point rise in rates (from 4% to 5%) costs very different amounts depending on when you leave. Using the simplified formula on $100,000 subject to the adjustment:

These are not predictions; rates may move less or more, and the figures assume the simple formula. They show why an exit early in a long guarantee period is the most sensitive to rates, and why the same exit near the end barely registers. The pattern also explains the advice to ask for a one-point sensitivity calculation. It turns an abstract provision into a dollar range you can compare with your need for the money.

Common misreadings

A few ideas about MVAs are widespread and worth correcting.

• "An MVA means I can lose my principal." Most contracts that include an MVA also guarantee a minimum value, so the adjustment cannot take the exit value below that floor. The floor may be below your premium in some contracts, which is a separate question to check.
• "An MVA only hurts." It works in both directions in many contracts, though some limit the upward adjustment. Read the terms rather than assuming.
• "The MVA is the same as the surrender charge." They are different provisions with different purposes. The charge is a fixed schedule, and the MVA reflects rates. Both can apply to the same withdrawal.
• "It applies to everything I take out." Free withdrawals, death benefits and the end of the guarantee period are commonly outside it.
• "The insurer decides the adjustment case by case." The formula is fixed in the contract, with the reference rate taken from a source it names. If the amount seems wrong, ask for the calculation and the reference rate on both dates.

Questions to put to the insurer

Customer service can run a calculation for you. These requests produce something you can plan with:

• What is my surrender value today, including the MVA, and what is the MVA amount on its own?
• What reference rate does the contract use, and what was it on my issue date and today?
• How would the value change if the reference rate moved up or down by one percentage point?
• Does the MVA apply to withdrawals above the free amount, or only to a full surrender?
• What is the guaranteed minimum value, and could the MVA take me down to it?
• Is the adjustment applied before or after the surrender charge?
• Does the MVA stop applying before the surrender period ends, and on what date?
• Does the MVA apply at death, on annuitization or at the end of the guarantee period?

Ask for the answers in writing. If you are comparing two contracts before buying, ask each for the same list. A contract without an MVA is not automatically better, because the lack of one may show up as a lower crediting rate or a steeper surrender charge. The comparison is whole-contract, not provision by provision.

How the MVA changes the way you think about leaving

Because the adjustment can go either way, it changes the logic of exiting early. In a falling-rate period, leaving can be less costly than the surrender schedule alone suggests, and in a rising-rate period it can be more costly. That makes the timing of an exit a rate question as well as a calendar question.

But two cautions apply. A rise in rates also means that new contracts may pay more than the one you hold, so the pull to move is strongest exactly when the MVA penalizes moving. Weigh the higher rate on the new contract against the adjustment, any surrender charge and the surrender period that restarts. The post on rates rise after you buy: what happens to the fixed annuity you hold works through that situation. And the same logic runs the other way: a fall in rates makes an exit look attractive on the MVA but may leave you with fewer attractive places to put the money.

For people who hold the contract to the end of the term, the MVA does nothing. If you are sure you will not need the money before the guarantee ends, the provision matters mostly at the margins: it may be the reason your rate is what it is, and it neither helps nor hurts you. Someone who may need the money in an emergency should read it as a variable cost with a floor.

Questions about whether an MVA was explained properly at the time of sale are a matter for the insurer first and then your state insurance department. A fee-only financial planner can help you compare a contract with an MVA against alternatives, such as a multi-year guaranteed annuity without one or a bank CD.

Key takeaways

• An MVA adjusts your exit value for changes in interest rates since you bought: generally down when rates are higher, up when rates are lower.
• It usually applies to full surrenders and withdrawals above the free amount during the surrender period, and often does not apply to free withdrawals, death benefits or the end of the guarantee period.
• The size of the adjustment grows with the rate change and the time remaining, and it is usually limited by a guaranteed minimum value.
• The formula, the reference rate and the order of operations are written in the contract, so ask the insurer for a written calculation before you decide.
• A contract with an MVA is a trade-off, not a flaw: it can be linked to a better crediting rate, and it can cost you or help you on an early exit.
