The $185,000 Portfolio That Covers Groceries, Utilities, and the Phone Bill Every Month

A $185,000 portfolio sounds like it should do a lot of work. At current safe yields, it does one specific job well: it covers the three recurring bills that appear in every household budget each month. Those bills are groceries, utilities, and the phone bill, with nothing fancier included.

The math starts with what cash and short-duration Treasurys actually pay right now. The 10-year Treasury yield is 4.4% as of June 24, 2026. The 52-week T-bill yields 3.99%, and the 26-week bill yields 3.95%. The federal funds upper bound is 3.75%, which sets the floor for money market funds and short-term cash. Applied to $185,000, a blended yield in the 4% range produces roughly $7,400 a year, or about $617 a month.

That figure is calibrated to the three categories that account for the most predictable part of a household’s monthly outflows. The Bureau of Labor Statistics put average annual household expenditures at $78,535 in 2024, up from $77,280 in 2023 and $72,973 in 2022. Food at home, utilities, and telephone services typically account for about 10% of that total for a middle-income household, which is the slice the portfolio is built to absorb.

Why this slice, and why now

Groceries, utilities, and phone bills behave differently from discretionary spending. They arrive on a schedule, they rarely shrink, and they track inflation closely. The Consumer Price Index reached 335.123 in May 2026, up from 321.435 a year earlier. National food spending hit $1,566.8 billion in May 2026, and the other services category, which includes utilities and communications, reached $1,849.9 billion. These are the line items that move up and stay up.

Carving them out of earned income and routing them to portfolio income is what the $185,000 number is for. The national savings rate fell to 3.9% in 2026 Q1, down from 6.2% in 2024 Q1, with per capita disposable income at $68,391. Consumption now absorbs 92.3% of disposable income. When wages cover almost everything, and savings cover almost nothing, having a separate pile of capital to cover fixed bills is one way to stop the leak.

What the portfolio actually looks like

The construction is conservative because the job is narrow. A T-bill ladder using 13-week, 26-week, and 52-week bills locks in yields in the 3.79%-3.99% range while staggering maturities for monthly cash flow. The national average 12-month CD rate of 1.65% is not competitive here, though top online banks pay multiples of that figure. Treasurys also carry the side benefit of state tax exemption, which matters in higher-tax states.

Where the $617 actually goes the furthest

The same monthly income buys different lives depending on the zip code. Mississippi has a cost-of-living index of 87, Arkansas 87, and Iowa 88. The same portfolio income covers a meaningfully larger share of essentials in those states. At the other end, California sits at 111, Hawaii at 110, and the District of Columbia at 110, where $617 a month closes a smaller fraction of the same three bills.

Gasoline is an honorable mention. The national average price sits at $3.91 per gallon as of June 22, 2026, down from a May 11 peak of $4.50. That decline is real relief, but fuel is not the bill this portfolio targets.

The limits

The structure does not cover rent, healthcare, or insurance, which are the larger line items in the $78,535 average. It also assumes yields hold. The federal funds rate remains within the 3.50%-3.75% range, but market signals are shifting. The $185,000 figure is sized to today’s curve, not last year’s and not next year’s.

What it does cover is the three bills that arrive, whether or not the paycheck does. For a household trying to insulate the predictable part of the budget from the volatile part of earned income, that is the version of the math that matters.
