How Much a 74-Year-Old Widow Must Invest to Recreate a $2,100 Monthly Social Security Check

When one Social Security payment vanishes from a widow’s monthly budget, the shortfall appears quickly and the answer is not always simple. A two-holding portfolio can make up the difference, but the amount needed to build it may surprise many investors.

In many cases, the change becomes clear about a month after a spouse dies: two Social Security deposits used to arrive, and now only one does. If the smaller benefit was $2,100 per month, that is $25,200 a year no longer in the budget. Here is a straightforward two-asset portfolio designed to replace that income, along with the funding required to do it.

Why One Check Disappears

After a spouse dies, Social Security pays the survivor whichever of the two benefits is higher, but not both. That means the larger payment continues while the smaller one stops. For perspective, the average widowed beneficiary living alone receives about $1,919 a month after the 2026 cost-of-living increase. A separate discussion of widow tax brackets explains how filing status changes. The benefit choices couples make years earlier can affect which payment lasts longer, which is why survivor-benefit planning matters.

Why Tax-Free Income Matters More for a Widow

She now files as a single taxpayer, so the brackets are narrower. In 2026, a single filer reaches the 22% bracket once taxable income exceeds $50,400. A married couple did not reach that level until $100,800. Her standard deduction also falls to $16,100, compared with $32,200 for a couple.

Municipal bond interest is generally exempt from federal income tax, allowing her to keep and spend the full amount. There is a catch, though. To determine how much of her Social Security is taxable, the IRS adds half of her benefits to all other income, including tax-exempt interest. That combined figure is compared with a $25,000 base for single filers. Medicare’s income-related surcharge works in a similar way. The law also allows Social Security to use tax-exempt interest information from IRS records when setting those premiums.

How Much Capital Is Needed

The portfolio is divided evenly between two holdings. Using recent closing prices, the fund yields about 7.8%, the utility about 3.4%, and the combined yield works out to roughly 5.6%. At that level, replacing the full $25,200 requires about $453,000 total, or roughly $226,000 in each holding.

A Monthly-Paying Municipal Fund

Nuveen AMT-Free Quality Municipal Income Fund (NYSE:NEA) invests in investment-grade municipal bonds, though up to 20% of assets may go into lower-rated or unrated securities. Its income is generally exempt from regular federal income tax and the alternative minimum tax, which can affect some municipal-bond interest. Because it is a closed-end fund, its share count remains fixed and the shares trade like a stock. The market price can rise above or fall below the value of the underlying bonds, known as net asset value. Nuveen publishes that discount or premium, along with the payout rate based on net asset value, on the fund’s website. A discount means the shares trade below the value of the bonds; a premium means they trade above it.

At around $11 per share, the fund pays $0.068 each month. Her half of the portfolio would generate about $17,600 a year, paid monthly. The fund also uses borrowing to buy more bonds than shareholder capital alone would allow. That can boost income when borrowing costs are low, but it can reduce income when rates rise.

The payout is not fixed. It was reduced from $0.073 to $0.068 in October 2025, and it was as low as $0.035 in 2023.

A Regulated Utility With a Long Dividend Record

NorthWestern Energy (NASDAQ:NWE) provides electricity and natural gas to about 850,300 customers across Montana, South Dakota, Nebraska, and Yellowstone National Park. State regulators determine its rates, which supports steadier profits but slower growth. Management is targeting annual earnings growth of 4% to 6%, making it the more stable, slower-moving half of the portfolio.

At roughly $80 per share, the company’s annual dividend of $2.68 equals a yield of about 3.4%. Her half would produce around $7,600 a year, paid quarterly. The quarterly payout has climbed from $0.33 in 2008 to $0.67 now. It currently uses about 96% of trailing earnings. Based on the low end of 2026 guidance, which calls for earnings of $3.68 to $3.83 per share, that payout ratio falls to about 73%. Dividends from domestic corporations usually qualify for lower capital-gains tax rates if held long enough, and in 2026 a single filer with taxable income up to $49,450 owes 0% on them.

A pending all-stock merger with Black Hills (NYSE:BKH | BKH Price Prediction) still requires Montana approval, and the company expects to begin issuing new shares in 2027.

Why This Portfolio Leaves Little Margin for Error

This is still a relatively small portfolio, and both a leveraged bond fund and a single utility can weaken if interest rates rise. Neither income stream is guaranteed. Cash flow could decline, so before acting on this idea, she would be wise to review it with a fee-only adviser who charges a flat fee rather than commissions.

The One Figure to Review Each Year

About $453,000, split evenly, is enough to replace the $2,100 monthly check. NorthWestern provides the steadier dividend, while the Nuveen fund supplies most of the income. Each January, the fund’s monthly payout should be compared with $0.068, along with its discount to net asset value. If the payout has been cut, the budget gap opens again and the plan needs to be adjusted.
