A roll-up rate in an annuity is a guaranteed annual percentage increase, commonly 4% to 8%, that the insurance company applies to a separate ledger figure called the benefit base. That benefit base is used to calculate your future lifetime income. It is not credited to your actual account balance, and you cannot withdraw it as cash. The roll-up looks like an investment return on your statement, but it functions as a promise about how your future income will be calculated.
The Two Numbers Inside Your Contract
When you buy a deferred annuity with a Guaranteed Lifetime Withdrawal Benefit (GLWB) rider, the insurer tracks two separate values side by side.
The contract value is real money. It holds your deposit plus or minus investment performance, minus fees. You can surrender for it, your beneficiaries generally receive it at death, and it rises and falls with the market or earns a fixed rate depending on the product.
The benefit base is a phantom number. It exists only to calculate future income. It grows each year by the roll-up rate regardless of market performance, but you cannot withdraw it as a lump sum and it is not paid out as a death benefit in a standard contract. If you surrender the annuity, you walk away with the contract value only.1Interstate Insurance Product Regulation Commission.

That is the source of most confusion around roll-up rates. The benefit base can compound at 6% or 7% a year while the contract value sits flat or declines through a bad market stretch. The gap between the two numbers is not a loss, but it is also not wealth you can spend.
Simple vs. Compound Growth
Contracts calculate roll-up growth one of two ways, and the difference over a long accumulation period is large.
A simple roll-up applies the percentage to your original deposit every year. A 5% simple roll-up on $100,000 adds exactly $5,000 to the benefit base each year, reaching $200,000 after 20 years.
A compound roll-up applies the percentage to the previous year’s benefit base, so growth accelerates. That same 5% compounding on $100,000 produces a benefit base of roughly $265,000 after 20 years. Carriers offering compound roll-ups often charge higher rider fees or publish a lower headline percentage to offset the richer math. A 7% simple roll-up can produce less income than a 5% compound roll-up over a long deferral period, so match the method before comparing two contracts.
How the Benefit Base Turns Into Income
The roll-up only matters because the benefit base eventually gets multiplied by a payout factor to produce your guaranteed annual income. The formula is simple: benefit base × payout factor = annual lifetime income.
Payout factors are set by the insurer and depend on your age when you turn on income. A typical schedule might offer 4% at age 60, 5% at age 65, and higher percentages later. A $200,000 benefit base activated at age 65 with a 5% payout factor produces $10,000 per year for life.
Waiting longer usually helps twice: more roll-up years build a bigger base, and an older activation age qualifies for a higher payout factor. Waiting too long can hurt, though, because the roll-up period itself has an expiration date.
When the Roll-Up Stops
Roll-up rates do not run forever. Most contracts cap the guarantee at a set number of years, often 10 or 12 from the initial deposit, or until the owner reaches a specified age such as 85 or 90.2Nationwide.

It will not decline from that cause, but it will not grow from the roll-up either.
Starting lifetime income also stops the roll-up in most contracts. The moment the insurer begins systematic payments, accumulation ends and the payout phase begins. The planning tension is real: you want the roll-up to run as long as possible, but you do not want to sit past the expiration and leave years of growth on the table.
Step-Ups: The Other Way the Base Can Grow
Many GLWB riders include a step-up or ratchet feature alongside the roll-up. On each contract anniversary, the insurer compares your actual contract value to the current benefit base. If market gains have pushed the contract value above the rolled-up benefit base, the benefit base resets upward to match.3Morningstar. How Guaranteed Lifetime Withdrawal Benefits Work
In practice, the benefit base follows whichever path is higher: the guaranteed roll-up rate or the actual market performance captured through step-ups. In a bull market, step-ups can push the base well above what the roll-up alone would have produced. In a downturn, the roll-up acts as a floor. Some contracts check for step-ups annually, others quarterly or on specified dates, so read the rider specifications.
How Withdrawals Can Shrink the Benefit Base
Taking money out before you turn on scheduled income is one of the fastest ways to damage a roll-up guarantee. Most contracts allow a penalty-free withdrawal of up to 10% of the account value each year without disrupting the rider. Exceeding that triggers what the industry calls a pro-rata reduction: the benefit base is reduced by the same percentage the withdrawal represents relative to your contract value, not by the dollar amount withdrawn.
Say your contract value is $100,000 and your benefit base has rolled up to $150,000. You withdraw $20,000, which is 20% of your contract value. The insurer reduces your benefit base by 20% as well, dropping it from $150,000 to $120,000. You lost $30,000 off the benefit base even though you only took $20,000 in cash. In many contracts, excess withdrawals also stop future roll-up growth entirely, turning a one-time need for cash into a permanent cut to guaranteed income.
IRA Annuities and RMDs
If the annuity is held inside an IRA, the IRS Required Minimum Distribution may exceed the GLWB’s allowed withdrawal percentage. When that happens, the excess over the GLWB amount can be treated as an excess withdrawal and trigger the same pro-rata reduction. Some carriers build in provisions that accommodate RMDs without penalizing the benefit base. This is not universal. If you are funding an IRA annuity with a roll-up rider, confirm how the contract handles RMDs before purchasing.
What You Pay for the Guarantee
The roll-up is not free. GLWB rider fees typically run 0.95% to 1.40% annually, charged against the contract value or the benefit base depending on the carrier. On a variable annuity, that fee stacks on top of mortality and expense charges, administrative fees, and investment management costs, and combined annual costs can reach 3% or more.
Those fees come out of your real money, not the phantom benefit base. So while the base grows at the roll-up rate on paper, the contract value is being eroded by fees every year. In a flat or declining market, the two numbers drift further apart. The benefit base can look impressive on an annual statement while the surrender value shrinks. You are paying real fees for a guaranteed income stream, not for growth you can touch.
Premium Bonuses Attach to the Base
Some contracts offer a premium bonus of 5% to 10% on your initial deposit. That bonus almost always applies to the benefit base rather than the contract value. A $100,000 deposit with a 10% bonus starts with a $110,000 benefit base but only $100,000 in actual cash value, and the roll-up then compounds on the higher figure.
Bonus contracts often carry longer surrender periods, higher rider fees, or lower payout factors to offset the head start. The bonus gets the benefit base off to a faster start; the total cost over 15 or 20 years may exceed what that head start is worth. Run the numbers across the full expected holding period before letting a bonus drive the decision.
