Market value adjustment on an annuity: how an MVA works and when it costs you

A market value adjustment is a clause in a fixed annuity that changes the amount you receive if you take money out early, based on how interest rates have moved since you bought the contract. If rates have risen, the adjustment is usually negative and you get less. If rates have fallen, it is usually positive and you get more. It applies on top of any surrender charge, not instead of it.

Most people meet the MVA at the worst possible moment: when they have already decided to exit and are looking at a number on a surrender quote that is smaller than the account value on their statement. The mechanics are not complicated, but they are rarely explained at the point of sale, and the direction of the adjustment surprises people because it runs opposite to the way they instinctively expect a rate change to affect them.

Why the clause exists at all

When you hand an insurer a single premium and it guarantees you a rate for seven years, it does not park the money in a bank account. It buys bonds with maturities that roughly match the seven-year promise it has just made. That matching is the whole business model of a fixed annuity: the insurer earns the spread between what the bond portfolio yields and what it credits to you.

The problem is what happens if you leave early. The insurer has to raise cash, which means selling bonds before maturity. Bond prices fall when interest rates rise, so in a rising-rate environment those bonds are worth less than the insurer paid. Without a market value adjustment, the insurer would absorb that loss and every remaining contract holder would effectively subsidise the person walking out.

The MVA passes that specific cost back to the person causing it. It is not a penalty in the way a surrender charge is. It is a transfer of the interest rate risk that the insurer took on to fund your guarantee.

Two practical consequences follow. First, contracts with an MVA can often offer a slightly higher credited rate than otherwise identical contracts without one, because the insurer is carrying less liquidity risk. Second, the adjustment genuinely can work in your favour, which a plain surrender charge never does.

How the adjustment is calculated

Every insurer uses its own formula and the exact wording sits in the contract, but the structure is consistent across the market.

The formula compares a reference rate at the time you bought the contract with a reference rate at the time you withdraw, then scales the difference by the time remaining in the guarantee period. The reference is typically a published yield such as a US Treasury constant maturity yield, or a corporate bond index, sometimes with a small fixed spread added.

Three things drive the size of the adjustment:

Factor	Effect
Direction of rate movement	Rates up since purchase means a negative adjustment; rates down means a positive one
Size of the movement	A larger gap between the two reference rates produces a larger adjustment either way
Time left in the term	The adjustment shrinks as you approach the end of the guarantee period and reaches zero at the end

That last point matters more than the other two for most people. An MVA on a contract with six years left is a serious number. The same contract with four months left produces an adjustment close to nothing, because the insurer can hold the bonds to maturity rather than selling at a loss.

An illustrative example

The figures below are invented to show the mechanics. They are not a quote, not an average, and not a prediction. Every contract's formula differs.

Suppose someone bought a five-year fixed annuity with $100,000 and there are three years left to run. The contract has a declining surrender charge, currently 5%, and an MVA tied to a Treasury reference rate.

Scenario one, rates have risen. The reference rate was 4.0% at purchase and is 6.0% today. The gap is 2 percentage points against the insurer, applied across roughly three remaining years. A simplified adjustment of that shape might reduce the surrender value by something in the region of 6%. Add the 5% surrender charge and the exit costs around 11% of the account value.

Scenario two, rates have fallen. The reference rate was 4.0% at purchase and is 2.5% today. The adjustment now runs in the contract holder's favour and might add roughly 4%. The 5% surrender charge still applies, so the net exit cost is around 1%.

Same contract, same account value, same day of the week. The only variable is what happened to interest rates in the meantime, and it moves the outcome by roughly ten percentage points. Rates and formulas change constantly, so treat this only as a demonstration of direction and scale, and get an actual surrender quote from the insurer before acting on anything.

The floors that limit the damage

An MVA is not unlimited. State insurance regulation and standard non-forfeiture requirements put boundaries on it, and the contract will state them.

The most important is the guaranteed minimum surrender value. Every fixed annuity has a floor value calculated under state non-forfeiture law, and a negative market value adjustment generally cannot push your surrender proceeds below it. In a severe rate spike this floor is what stops the adjustment from consuming principal without limit.

Many contracts also cap the adjustment in the other direction, so a positive MVA cannot take your surrender value above the accumulation value shown on your statement. Read your own contract rather than assuming, because this varies.

State variation is real. An MVA feature has to be approved by the insurance regulator in each state where the contract is sold, and some insurers issue a version of the same product without the MVA in particular states. Two neighbours who bought what looks like the same annuity in different states can have genuinely different exit terms. Your state insurance department is the authority on what was approved for sale where you live.

When the MVA does not apply

This is the part worth knowing before you sign, because these carve-outs are what make the clause tolerable.

• The free withdrawal allowance. Most fixed annuities let you take a set percentage of the value each year, commonly around 10%, with no surrender charge and no market value adjustment. Withdrawals inside that allowance are untouched.
• End of the guarantee period. Once the surrender charge period ends, the MVA ends with it. Waiting is the cheapest exit strategy there is.
• Death benefit. Most contracts waive the MVA on the death benefit paid to a beneficiary, though not universally. If the contract is part of an estate plan, confirm this specifically, and read it alongside how the annuity death benefit is calculated in the first place.
• Annuitization. Converting the contract to an income stream under its own annuitisation provisions usually avoids the adjustment entirely, sometimes after a minimum holding period.
• Required minimum distributions. Where the annuity sits inside an IRA or qualified plan, many contracts waive charges and the MVA on amounts you are legally required to withdraw.
• Contractual waivers. Nursing home confinement, terminal illness and disability waivers commonly suspend both the surrender charge and the MVA. Their trigger conditions are precise and worth reading before you need them.

MVA and surrender charge are two separate things

A recurring source of confusion. The surrender charge is a flat penalty that declines on a published schedule and only ever reduces what you receive. It compensates the insurer for its acquisition costs, mostly the commission it paid up front. The MVA is a bidirectional adjustment for interest rate movement and can go either way.

They stack. On an early exit in a rising-rate market you pay both, and the combined figure is what surprises people. The wider mechanics of surrender periods, commissions and the way those costs are recovered are covered in annuity fees and surrender charges.

The stacking also affects the arithmetic of switching contracts. A 1035 exchange into a better-paying annuity is tax-free, but the tax treatment says nothing about the economics. If the exit costs 11% and the new contract pays one percentage point more, the exchange takes many years to break even. Whoever proposes the switch should show you that calculation with real surrender figures before you agree, and if they will not, that itself is the answer.

What to check before you buy

Five questions, all answerable from the contract or the disclosure statement:

1. Does this contract have a market value adjustment, and is that version the one sold in my state?
2. What is the reference rate in the formula, and is it published somewhere I can look up?
3. Is the adjustment capped in either direction, and what is the guaranteed minimum surrender value?
4. Which events waive it: death, annuitisation, RMDs, nursing home confinement, terminal illness?
5. How much can I withdraw each year without triggering it at all?

If you are comparing contracts, an MVA is not automatically a mark against one. A MYGA with an MVA and a higher credited rate can be the better deal for money you genuinely will not touch for the full term. It is a worse deal for money that might be needed early. The feature is only expensive if your plans change, which is precisely why the honest question to ask yourself is how confident you are about the term, not how attractive the rate looks. You can model what the guaranteed rate compounds to over the term with the fixed annuity calculator, but the exit cost is a separate calculation the insurer has to give you.

If you have already decided you want out, the full set of exit routes, including the ones that avoid the adjustment, is set out in how to get out of an annuity.

Frequently asked questions

Can a market value adjustment ever increase what I receive?

Yes. If the reference rate has fallen since you bought the contract, the adjustment is positive and increases your surrender value. Many contracts cap that increase so it cannot exceed your accumulation value, and the surrender charge still applies separately, so a positive MVA reduces the cost of leaving rather than making it free.

Does the MVA apply to my whole account value?

No. It applies only to the amount you withdraw above the contract's free withdrawal allowance, and only during the surrender charge period. A withdrawal within the annual free amount is not adjusted, and neither is anything taken after the guarantee period ends.

Do variable annuities have market value adjustments?

Generally not in the same form, because a variable annuity's subaccount value already moves with the markets. The feature belongs to fixed and fixed-indexed contracts, where the insurer has guaranteed a rate and matched it with bonds. Some variable contracts do include an MVA on a fixed account option inside them, so check the specific contract rather than the product category.

How do I find out what my MVA would be right now?

Ask the insurer for a current surrender quote in writing. It will show the account value, the surrender charge, the market value adjustment and the net proceeds. The quote is valid only for a short window because the reference rate moves daily. Do not rely on an agent's estimate or on the figure printed on last quarter's statement.

This article is general education about how a contract feature works, not personal financial advice. Annuity contracts differ substantially in their formulas, floors and waivers, and rates change daily. Read your own contract and confirm the numbers with the issuing insurer, your state insurance department, or a licensed adviser who is not being paid a commission on the transaction, before you act.
