A roll-up rate in an annuity is a guaranteed annual percentage increase the insurance company applies to a bookkeeping figure inside your contract, usually tied to a living benefit rider such as a Guaranteed Lifetime Withdrawal Benefit. It does not grow the cash you can walk away with. It grows a separate number the insurer later uses to calculate how much lifetime income it owes you. Because that number rises at a fixed rate regardless of what markets do, it sets a floor under your future retirement income.
The Benefit Base Is Not Your Money
The figure that grows through the roll-up is called the benefit base, sometimes the income base. It is an internal ledger the insurer keeps alongside your real account. Your actual contract value moves up and down with your investments or index credits. The benefit base only moves in one direction: up, at the rate locked in when you bought the rider.
This distinction controls what the roll-up is actually worth to you. If you cancel the contract, you receive the surrender value, meaning your actual cash minus any surrender charges. You do not receive the benefit base. A roll-up might push the benefit base to $250,000 while the liquid account sits at $180,000. The only way to reach the full benefit base is to convert it into a stream of lifetime income payments. You cannot take it as a lump sum.p>
The insurer uses the benefit base for two things: as the starting figure for your future annual income, and as the amount the rider fee is calculated against each year.
How the Roll-Up Grows the Benefit Base
Insurers apply the annual increase in one of two ways, and the difference compounds into real money over a long deferral.
Simple Interest
A simple interest roll-up applies the rate to your original deposit only. Put in $100,000 with a 7% simple roll-up, and the benefit base rises by $7,000 every year, the same dollar figure regardless of what the base has already reached. After 10 years, the base is $170,000.
Compound Interest
A compound roll-up applies the rate to the current benefit base, including prior increases. With the same $100,000 and 7%, the first year adds $7,000, the second year adds $7,490, and so on. After 10 years the benefit base reaches roughly $196,700, about $26,700 ahead of the simple version. Over 15 or 20 years, that gap widens sharply.
Step-Ups and Ratchets
Many contracts pair the roll-up with a step-up feature, also called a ratchet. On each contract anniversary, the insurer compares your actual account value to the current benefit base. If the account value is higher because markets did well, the benefit base steps up to match, and future roll-up increases run from that new starting point. The roll-up protects the floor; the ratchet lets the base capture strong market years.
When the Roll-Up Stops
Guaranteed increases do not run forever. Every contract sets an end point, and knowing yours is essential to planning when to turn on income.
Most roll-ups last 10 to 20 years from your initial deposit. Some contracts instead use an age cap, commonly between 80 and 85, after which the roll-up ends. A few use both and stop at whichever comes first.
The roll-up also ends the moment you activate the income rider and start taking lifetime withdrawals. Buy an annuity at 55 with a 10-year roll-up and the base stops growing through the roll-up at 65. Waiting longer to start income does not add more roll-up growth, though it may qualify you for a higher payout percentage.
Some insurers offer to renew the roll-up after the initial period, typically at a lower guaranteed rate, and they may adjust the rider fee at the same time.
How the Benefit Base Becomes Income
When you turn on the income rider, the insurer multiplies your final benefit base by a payout percentage set by your age at that time. Older starting ages get a higher percentage because the insurer expects to pay for fewer years. A common schedule looks roughly like this:
- Age 60: around 4% of the benefit base per year
- Age 65: around 5%
- Age 70: around 5.5%
- Age 75: around 6%
- Age 80: around 7%
These figures vary by carrier and contract, and the specific schedule is locked in when you buy the rider. At 5% and a $300,000 benefit base, you would receive $15,000 a year for life. Wait until 75 and qualify for 6%, and the same base produces $18,000 a year.
Once payments start, the insurer keeps sending them even if your actual account value eventually drops to zero from withdrawals, fees, or market losses. That guarantee is the point of the roll-up rider.
Excess Withdrawals Can Permanently Cut the Base
Taking more than your allowed annual withdrawal can damage the benefit base out of proportion to what you took. Most contracts treat anything above the guaranteed amount as an excess withdrawal and reduce the base proportionally, not dollar-for-dollar.
The math works like this. The insurer divides the excess by your contract value immediately before the withdrawal, then cuts the benefit base by that same percentage. Say your contract value is $200,000 and your benefit base is $300,000, and you take $20,000 above the allowed amount. That excess is 10% of the contract value, so the insurer reduces the benefit base by 10%, from $300,000 to $270,000. A $20,000 excess withdrawal has cost the benefit base $30,000. Because the benefit base almost always sits above the contract value, proportional cuts land harder than they look.
Required minimum distributions from a qualified annuity held inside an IRA are typically excluded from this treatment. Any other withdrawal above the guaranteed annual amount triggers the reduction.
The Rider Fee
The guaranteed growth is not free. Annual rider fees for GLWB-type riders typically run from about 0.95% to 1.40% of the benefit base per year. That is on top of the annuity’s other charges, such as mortality and expense fees and any investment management fees on variable subaccounts.
One detail matters more than it first appears: the rider fee is calculated on the benefit base, which is the higher number, but deducted from your actual contract value, which is the lower one. As the roll-up widens the gap between the two, the fee takes a bigger bite of your real money each year. In a flat or falling market, that drag can accelerate the depletion of the account value.
None of this cancels the guarantee. Even if your account value hits zero, the insurer still owes the lifetime income. But you may end up with little or no cash available to withdraw as a lump sum or pass to heirs outside the income stream.
What Beneficiaries Receive
The benefit base does not pass to your heirs. If you die before or during the income phase, beneficiaries generally receive the actual contract value or a separate death benefit, not the inflated benefit base. Some contracts guarantee beneficiaries at least the total premiums paid, but that figure is distinct from, and typically well below, a benefit base that has been rolling up for years.
If leaving money to family matters as much as guaranteed income, a large benefit base is not the plan. You would need a separate death benefit rider, which carries its own fee.
How Roll-Up Income Is Taxed
Tax treatment depends on whether the annuity was funded with pre-tax or after-tax dollars and on how you take the money out.
Lifetime Income Payments
Once you activate the income rider and receive regular payments, each payment is split for tax purposes. A portion is treated as tax-free return of your investment in the contract, and the rest is taxed as ordinary income. The IRS uses an exclusion ratio, dividing your investment in the contract by the expected total return, to set the tax-free percentage of each payment. That ratio holds until you have recovered your full original investment; after that, every dollar of each payment is fully taxable.1Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts
Withdrawals Before You Turn On Income
Withdrawals from a non-qualified annuity, meaning one funded with after-tax money, come out on a last-in, first-out basis before the income rider is activated. The IRS treats the first dollars out as earnings, fully taxable as ordinary income. Only after all of the contract’s gains have been withdrawn do further amounts come from your original premium tax-free.2Internal Revenue Service. Publication 575, Pension and Annuity Income
The 10% Early Withdrawal Penalty
Money taken from an annuity before age 59½ is generally subject to a 10% additional tax on the taxable portion, on top of ordinary income tax. Exceptions include disability, distributions structured as substantially equal periodic payments over your life expectancy, and certain qualified plan distributions.1Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts
Every roll-up rate, calculation method, payout table, age cap, fee, and excess withdrawal rule is set in the rider endorsement attached to your contract. That endorsement, not the marketing brochure, is the binding document. Read it before you sign.
