What Closes It
A readiness gap is an income gap
Readiness is measured per month, not per balance
Every figure in the MFS survey is about accumulation: save more, work longer, competing priorities. None of them answer the question a 65-year-old actually faces, which is what the accumulated balance pays per month for as long as the owner lives.
That distinction is not academic. A balance can be large and still produce uncertain income if the withdrawal rate is set by guesswork, and a smaller balance can produce a known monthly figure if part of it is converted into a contractual income stream. Readiness is the second measurement, not the first.
When MFS asked participants which financial wellness topics they most wanted help with, retirement income planning ranked most important overall, ahead of healthcare costs and Social Security for older workers and ahead of budgeting for younger ones. People are already asking the income question. The survey's confidence number just does not measure it.
What $100,000 converts into at 65
A single premium immediate annuity converts a lump sum into a fixed monthly payment for life. It is an insurance product, not an investment, and the payment is set at purchase based on age, sex, state, and the carrier's current rates.
Worked example, rates as of October 1, 2026:
$100,000 placed in a life-only single premium immediate annuity at age 65 was paying up to $693 per month for a man, $658 per month for a woman, and $608 per month for a couple with 100% of the payment continuing to the survivor (lifeannuities.us SPIA Payout Index, October 1, 2026).
At $693 per month, the annual income is $693 x 12 = $8,316, which is an 8.32% annual payout rate on the $100,000 premium.
That payout rate is not an interest rate and should never be compared with one. It blends return of the original principal with interest and with mortality pooling, which is why it exceeds any fixed annuity rate on the market. The tradeoff is that the $100,000 is no longer available as a lump sum.
Availability, payout amounts, and terms vary by carrier and by state, and rates are subject to change without notice.
Run that against the survey's own framing. A participant who says they need to work three years longer is, in effect, saying they need more monthly income than their current balance produces. Converting a portion of the balance into guaranteed income answers the same question from the other direction, by raising the income the existing balance produces rather than raising the balance.
What this example does not settle
It does not say an immediate annuity is the right answer for any particular person. Converting a lump sum into a lifetime payment is irreversible in most cases, it removes that money from the estate under a life-only payout, and the fixed payment loses purchasing power to inflation unless an increasing payout option is selected, which lowers the starting payment.
It also does not address the three-quarters of participants who said they need to save more. For someone still ten or fifteen years from retirement, the accumulation question is the live one, and a deferred product or a straightforward increase in contribution rate is the relevant lever. Principal protection and guaranteed income are distribution tools, not accumulation shortcuts.
What the example does establish is the shape of the actual question. Retirement readiness has a numeric answer. It is the gap between the monthly income a household needs and the monthly income it has contractually secured, including Social Security and any pension. Everything else, including a 41% confidence reading, is commentary on that number.
How to check your own gap
The arithmetic is short. Add the monthly income already guaranteed for life: Social Security, any defined benefit pension, and any annuity income already in force. Subtract that total from the monthly spending the household actually requires, not the figure a rule of thumb suggests. The remainder is the gap that savings must cover, and it is the only number in this exercise that is not a forecast.
From there the question becomes how much of that remainder should be converted into guaranteed income and how much should stay liquid. That decision depends on health, other assets, legacy intentions, and tax position, which is why it belongs in a conversation with a licensed professional rather than in a calculator. Availability and terms vary by state.
