What is an Annuity Spread Rate
Jason Stolz CLTC, CRPC
What is an annuity spread rate? In simple terms, it’s the difference between the interest an annuity earns and the amount the insurance company credits to your contract. This “spread” is one of the ways insurers cover their operating costs, maintain reserves, and provide the guarantees that make annuities attractive for retirement income.
Understanding the annuity spread rate helps you evaluate growth potential—especially when comparing how annuities earn interest across different companies. At Diversified Insurance Brokers, we help retirees and pre-retirees compare annuity designs, crediting methods, and rate structures so you can confidently choose the product that aligns with your goals.

The annuity spread rate—often called the “interest spread”—is the difference between the amount the insurer earns on its general account investments and the rate it credits to your annuity. For example:
- If the insurer earns 6% on its portfolio…
- But credits you 5%…
- The “spread” is 1%.
This spread helps support:
- Administrative costs
- Insurance reserves
- Guarantees (principal protection, lifetime income, etc.)
- Commission and distribution costs
Spreads exist in all types of annuities, including MYGAs, FIAs, deferred income annuities, and immediate annuities. How they work depends on the annuity design and crediting method.
How Spread Rates Work in Different Types of Annuities
Fixed Annuities (Traditional)
Fixed annuities credit a steady guaranteed rate. The insurer determines this guaranteed rate by factoring in expected investment yield minus spread.
If the company’s general account performs well, it may credit a renewal rate higher than expected. If performance declines, the renewal rate may decrease—within contract guarantees.
MYGA Annuities (Multi-Year Guaranteed)
With MYGAs, the insurer sets a guaranteed rate for 3–10 years. Spreads do not apply here in the same way, because the rate is locked in during the guarantee period.
To compare spreads and yields, see our pages on:
Fixed Indexed Annuities (FIAs)
In FIAs, spreads may appear as:
- Asset fees (spread fees) that reduce interest credited
- Participation rates that limit the percentage of index growth credited
- Cap rates that set maximum credited growth
For example:
If the index returns 8% and the spread is 2%, you may be credited 6%—assuming no cap or participation limit applies.
Some carriers use spread rates instead of caps because spreads allow unlimited upside above the fee. Others use spreads and caps in certain crediting methods.
Why Insurance Companies Use Spread Rates
The spread supports insurer solvency and enables them to offer guarantees like:
- Principal protection
- Guaranteed interest
- Guaranteed lifetime income
- Death benefits
- Enhanced benefits (LTC, chronic illness, etc.)
Maintaining a stable spread allows insurers to operate safely—even during volatile interest-rate environments. This ties directly into understanding what insurance companies do with your money.
How Spreads Affect Your Actual Growth
The spread rate influences:
- Your annual credited interest
- Your renewal rates after the guarantee period
- Your long-term accumulation potential
- Your annuity income later
Spread rates affect FIAs the most because they directly determine the portion of index growth you receive. However, MYGAs and fixed annuities also embed spreads into credited rates.
How to Compare Annuity Spread Rates Across Carriers
You can compare spreads indirectly by comparing:
- Credited rates
- Renewal rate history
- Cap and participation rates
- Spread fees disclosed in the contract
Direct comparisons are often difficult, which is why we provide side-by-side illustrations and access to the strongest current rates.

FAQs: Annuity Spread Rates
What is an annuity spread rate?
An annuity spread rate is the difference between what the insurer earns on its investments and the amount credited to your annuity. It supports guarantees, reserves, and operating costs.
Do all annuities have spread rates?
Yes. Every fixed, MYGA, and indexed annuity uses a spread to maintain financial stability. In FIAs, spreads may appear as asset fees, participation rates, or caps.
Can spread rates change over time?
MYGAs have fixed spreads during the guarantee period. Fixed and indexed annuities may adjust spreads or crediting components at renewal, depending on market conditions and company performance.
Are spread rates the same as annuity fees?
No. Spreads occur inside the crediting process. Additional fees—like rider charges—are separate and disclosed in the contract.
How do spreads affect my annuity’s performance?
Higher spreads reduce credited interest. Lower spreads generally support stronger long-term accumulation. This is especially important in indexed annuities.
