What Is a Market Value Adjustment (MVA) on an Annuity? (2026)

How a market value adjustment works

Every fixed annuity carrier sets aside a matching portfolio of bonds to fund the guaranteed rate it just promised you. That portfolio sits quietly in the background for as long as you hold the contract. Cash out early, though, and the carrier may need to unwind part of that portfolio before your term is up, and bond prices move opposite to interest rates. The MVA is simply the mechanism that passes a share of that gain or loss on to you.

Picture two opposite situations. Say you locked a 5-year MYGA at a hypothetical 5.00%, and by the time you want out, comparable rates have climbed to a hypothetical 6.00%. The bonds backing your contract are now worth less than they were, so the carrier would take a loss unwinding them, and your MVA lands as a negative number that trims your payout. Flip the scenario: rates slide from that same hypothetical 5.00% down to 4.00%, the underlying bonds are worth more than when you bought in, and the MVA turns positive, handing you a bit of that gain instead.

Neither direction has anything to do with how your contract is performing. It is entirely about where rates sit on the day you leave versus the day you signed.

How the MVA gets calculated

Carriers do not all use the identical formula, but most build it around a version of this:

MVA factor = 1 - [(1 + I) / (1 + J)]^(N/12)

Here, I stands for the reference rate on the day your premium was credited, J is that same reference rate on the day you surrender, and N counts the full months still left in your surrender period. The resulting factor gets multiplied against whatever portion of your accumulation value you are pulling out beyond your free withdrawal allowance, not against the whole balance.

Most carriers anchor I and J to a Constant Maturity Treasury yield that roughly matches the length of your surrender period, and many average that yield across four specific dates each month, typically the 1st, 8th, 15th and 22nd of the prior month, rather than using a single day's snapshot. If that particular Treasury series ever gets discontinued, carriers can usually swap in a replacement rate, though that substitution generally needs sign-off from state insurance regulators or the Interstate Insurance Product Regulation Commission first.

Here is what that math might look like in practice, using clearly hypothetical numbers rather than a live quote. Say you hold $100,000 of accumulation value with 24 months left in your surrender period, and you want to pull out $50,000 above your free withdrawal allowance.

The exact dollar swing depends on your carrier's formula and how many months remain, but the shape of it holds everywhere: a bigger rate move and more time left in your surrender period both make the adjustment larger in either direction.

When the MVA kicks in, and when it doesn't

Two situations trigger it, and both come down to taking money out sooner and in a bigger amount than the contract expects:

• A full early surrender. Cashing out the entire contract before your surrender charge period expires, whether that is because your plans changed or you found a better use for the money.
• A withdrawal above your free allowance. Most contracts let you pull roughly 10% of your value, or your accumulated interest, without penalty each year. Anything you take beyond that line, in that same contract year, is exposed to the MVA.

Four situations keep it away entirely:

• Withdrawals inside your free allowance never see an MVA, positive or negative.
• Death benefits typically pay out the full accumulation value with no adjustment. Losing a spouse or parent is hard enough without an insurer subtracting a rate-driven penalty from what the family receives, so carriers generally build in this exception on purpose.
• Annuitizing the contract, meaning converting it into a stream of income payments, generally sidesteps the MVA as well, since you are no longer surrendering the contract for a lump sum.
• Waiting out the surrender period removes the MVA entirely once those years have passed. From that point forward you can move money freely with no MVA and no surrender charge standing in the way.

MVA versus a surrender charge

These two penalties often get lumped together, but they behave nothing alike.

A surrender charge is a flat, published percentage that steps down on a fixed schedule you can read in the contract before you ever sign it, something like 8% in year one and a point lower each year after. An MVA carries no such predictability. It floats with the bond market, it can help you or cost you, and nobody, including your carrier, knows which way it will point until the day you actually withdraw. The rough part is that both can apply to the same withdrawal at once. A big early surrender during a rising-rate stretch can mean absorbing a scheduled surrender charge and a negative MVA in the same transaction, which is exactly why reading both provisions before you buy matters more than most people assume. Neither one touches your guaranteed rate or your death benefit; both are strictly early-exit penalties layered on top of an otherwise unaffected contract.

Which annuities actually carry an MVA

• MYGAs. Some multi-year guaranteed annuities include the clause and some skip it entirely. Carriers that build it in frequently offer a somewhat richer guaranteed rate to compensate. When you are comparing MYGA quotes, it is worth asking specifically whether each one carries an MVA, since two contracts advertising a similar headline rate can carry very different early-exit terms.
• Fixed index annuities. MVAs show up more often here, largely because FIA contracts tend to run longer surrender periods and sit on more complex investment structures behind the scenes.
• Immediate and deferred income annuities. These almost never carry an MVA, since the whole point of an income annuity is paying you now or soon, not holding a lump sum for years the way an accumulation product does.

None of this is a hard rule carved into every contract from every carrier. Always confirm the specific provision in the specimen contract rather than assuming based on product type alone.

Should you steer clear of MVA contracts

Not automatically. Three things are worth weighing before you rule one out.

The rate premium is real. Carriers that attach an MVA often pay more for taking on that rate risk, and if you hold the contract to the end of its term, the MVA provision never even activates. You simply pocket the higher guaranteed number.

Your read on where rates are headed matters too. If you expect rates to fall over your term and think there is a real chance you might need to exit early, an MVA could actually work in your favor rather than against you.

Your own liquidity picture matters most of all. If there is any real chance you will need the full balance back before the surrender period runs out, a contract without an MVA removes one more variable you would otherwise have to track.

The honest question to ask yourself is simple: how sure are you that you will ride this contract out to the end? The more confident you are, the more that extra rate on an MVA product starts to look like free money.

Picture two buyers with the same $100,000 and the same 5-year horizon. One is retired, living on a fixed budget with an emergency fund already set aside elsewhere, and does not expect to touch this money before the term ends. The other just started a small business and might need a large chunk of capital on short notice. The first buyer is a reasonable candidate for the MVA product and its extra rate. The second is probably better served giving up a little yield for the version without one.

How to protect yourself

• Read the MVA language before you sign, and ask whoever is helping you buy to walk through the exact reference rate and formula your contract uses.
• Lean on your free withdrawal allowance for any cash you might need along the way, since that portion never touches the MVA.
• Consider laddering shorter contracts instead of one long-term MYGA, which shrinks how much money is ever exposed to a single MVA calculation at once.
• Price both versions. Ask for an MVA quote and a non-MVA quote on the same term through our quote request before deciding the rate gap is worth the added variable.
• Check your state's guaranty association limit as a separate backstop, on top of understanding the MVA itself. Our guide to state guaranty associations has the figure for where you live.

None of these steps require avoiding MVA contracts altogether. They simply make sure you know exactly what you are agreeing to, so an early exit never comes as a surprise. An MVA is neither a red flag nor a bonus feature by itself. It is a mechanical response to how the bond market backing your annuity has moved, and it only matters at all if you leave the contract before the surrender period runs out. Hold the contract to term, as most buyers plan to, and the whole provision stays dormant while you collect whatever guaranteed rate you signed up for. The work worth doing up front is confirming how confident you are in that plan, then pricing the MVA and non-MVA versions of a similar contract side by side so the trade-off is one you made on purpose rather than one you discover later.
