The Income Gap: The Number That Actually Matters

Here's the way most people think about retirement: they accumulate a number. A 401(k) balance. A brokerage account total. An IRA statement. At some point, the number gets big enough that they feel ready — or it doesn't, and they feel anxious. Either way, the entire framework revolves around a pile of money and a hope that it lasts.

We think the better framework starts with income. Not how much you've saved — how much guaranteed monthly income will you have when you stop working?

Start with what you'll need each month. Housing, food, healthcare, insurance, the basics. For most people, that number is somewhere between $5,000 and $10,000 a month, depending on where they live and what their life costs. Then look at what's already guaranteed: Social Security, any pension income, any existing annuity payments. The distance between what you need and what's guaranteed — that's your income gap.

The income gap is the problem this entire page — and much of what we do — is designed to solve. Filling it with systematic withdrawals from a market-based portfolio is one approach, and for some people it works. But it requires the market to cooperate during the exact years you're pulling money out. If it doesn't — if you retire into a downturn and start drawing down a shrinking balance — the math can turn against you quickly. This is sequence-of-returns risk, and it's the reason a $1.5 million portfolio can run out of money while a $900,000 portfolio with guaranteed income never does.

The alternative is to fill part or all of that gap with instruments that contractually guarantee income regardless of what markets do. That's what SPIAs, FIAs with income riders, MYGAs, and cash value life insurance are designed for — and that's what we specialize in.

Why Guaranteed Income Changes Everything

The conventional retirement planning approach treats your savings as a single pool that you draw down over time. The standard guidance is the "4% rule" — withdraw 4% of your portfolio each year, adjusted for inflation, and hope the math holds for 30 years. It works in most historical backtests. But historical backtests don't retire into your specific sequence of returns.

Here's the problem with relying entirely on withdrawals from a market-based portfolio: the order in which returns occur matters as much as the returns themselves. A retiree who earns 8% average annual returns but gets the bad years first can run out of money. A retiree with the same 8% average who gets the good years first may never run out. Same average. Completely different outcome. You don't get to choose which sequence you receive.

Guaranteed income changes the equation because it removes the sequence problem for the income it covers. If $3,500 of your monthly need is covered by a SPIA and Social Security, you only need your portfolio to cover the discretionary spending. The portfolio can ride out downturns because you're not forced to sell into a falling market to pay the electric bill. You've turned a fragile plan into a resilient one — not by earning more, but by reducing the plan's vulnerability to things you can't control.

We see this constantly in our practice. A client comes in with $1.2 million in retirement accounts and genuine anxiety about whether it's enough. We run the income gap exercise and discover that Social Security plus a modest SPIA allocation fills 80% of their essential expenses. Suddenly, the portfolio isn't carrying the entire burden. It can be invested for growth without the pressure of monthly withdrawals that compound during downturns. The same $1.2 million feels completely different when it isn't the only thing standing between you and running out of money.

That shift — from "hoping the math works" to "knowing the essentials are covered" — is what guaranteed income actually provides. It's not about earning more. It's about removing the uncertainty from the income you cannot live without.

Frequently Asked Questions About Retirement Income

What is a retirement income gap?

Your retirement income gap is the difference between the guaranteed income you will have each month and the amount you actually need to cover your expenses. Start with your essential monthly costs, such as housing, food, healthcare, and insurance. Then add up your guaranteed sources, such as Social Security and any pension. Whatever is left over is the gap that has to be filled reliably, for life. Framing retirement around this monthly income gap, rather than around a single savings balance, is the core idea behind guaranteed-income planning.

What is the difference between a SPIA, a MYGA, and a fixed indexed annuity?

A single premium immediate annuity, or SPIA, converts a lump sum into a guaranteed monthly income that starts right away and lasts for life. A multi-year guaranteed annuity, or MYGA, works like a CD, locking in a guaranteed interest rate for a set term with tax-deferred growth, and returns your money at the end. A fixed indexed annuity, or FIA, with an income rider provides guaranteed lifetime income while letting the account value earn index-linked interest with a floor of zero. SPIAs are the simplest, MYGAs are for guaranteed growth, and FIAs add lifetime income with some upside potential.

Are fixed annuities safe if the insurance company fails?

Fixed annuities are backed by the claims-paying ability of the issuing insurer, and insurer failures have historically been rare. There are two additional layers of protection. First, insurers are required by state regulators to hold reserves and are monitored for financial strength. Second, every state has a guaranty association that provides coverage up to statutory limits if an insurer becomes insolvent. Choosing a financially strong carrier and staying within your state guaranty-association limits are the practical ways to manage this risk.

How much of my retirement income should be guaranteed?

There is no single right answer, but a common approach is to guarantee enough income to cover your essential expenses, the costs you have to pay no matter what, and to leave more flexible or discretionary spending to a market-based portfolio. That way a market downturn early in retirement does not put your basic needs at risk. The right mix depends on your expenses, your other guaranteed sources such as Social Security, your assets, and how much certainty you want. This is general education, not a recommendation for your specific situation.

How is a MYGA different from a bank CD?

A multi-year guaranteed annuity and a bank CD both lock in a guaranteed rate for a set term, but they differ in a few ways. A MYGA grows tax-deferred, so you are not taxed on the interest until you withdraw it, while CD interest is generally taxed each year. MYGA rates have often been competitive with or higher than CD rates. A CD is backed by FDIC insurance, while a MYGA is backed by the insurer and the state guaranty association. MYGAs also carry surrender charges if you withdraw early, so they are best for money you will not need during the term.

Can you lose money in a fixed indexed annuity?

A fixed indexed annuity credits interest based on a market index but has a floor, usually 0%, so a decline in the index does not reduce your account value from index losses. You will not lose principal to a down market. You can, however, be credited little or no interest in a year the index performs poorly, and withdrawals above the free amount during the surrender period can incur surrender charges. It protects principal from market loss, but it is not a high-growth investment.

Can life insurance provide tax-free retirement income?

Yes, when it is set up and funded correctly. Whole life or indexed universal life cash value can be accessed in retirement through policy loans and withdrawals. Because a loan is not treated as taxable income, the distributions generally do not appear on your tax return or affect the taxation of Social Security. This is a long-term strategy that typically requires 10 to 20 years of funding, not something you buy shortly before you need income. Taking too much can cause the policy to lapse, so it needs realistic design and ongoing management. This is general education, not tax advice.
