If you retire before Social Security starts, you have a gap to cover. Retire at 60 and claim at 67, that's a seven-year bridge. Wait until 70 and it's ten years. Most people fill that gap by selling shares out of the portfolio they spent 30 years building. Every house payment, every utility bill, every grocery run comes out of it.

The bridge years are the risky part

Say you've got a $1 million portfolio and you're spending $60,000 a year. That's a 6% withdrawal rate. Now the market drops 30% in your first year and the portfolio is down to $700,000. You still need $60,000, so you're pulling closer to 8.5%. That's the phase that breaks retirements.

Look at what changes when Social Security shows up. If it pays $30,000 a year, you only need $30,000 from the portfolio. Same portfolio size, and your withdrawal rate went from 6% to 3%. At 3% you're durable across just about any market we've had. The bridge years are the phase where your portfolio is most exposed to sequence of returns risk.

What the standard fix leaves on the table

The usual advice is to shift some of your stocks into bonds. Pick up any retirement book or talk to an advisor and that's what you hear. The logic holds. Bonds cut volatility in the years volatility hurts most, and you still capture some equity upside. The math does what it says it will do.

Three things it doesn't cover, and together they cost more than the volatility does. The first is the dividend catch-22. Say your $1 million portfolio throws off about $20,000 a year in dividends, a 2% yield, which is standard for a stock-heavy mix. You decide to go 70/30, so you sell $300,000 of equities and buy a $300,000 bond ladder. Your remaining $700,000 in equities now pays closer to $14,000. You just gave up $6,000 a year in income. The bonds pay interest and cover part of that, likely not all of it if you're spending $60,000 a year. The rest still comes from selling shares.

The second is health insurance. Retire before 65 and you're on the ACA marketplace until Medicare starts, and the premiums there can be a landmine. The third is that the lowest income years of your adult life are sitting right there in the bridge, and they're the best spot you'll ever have for Roth conversions.

Build an income floor instead

The move is to build a cash flow stream during the bridge years, the same way a paycheck worked when you had a job. Money arrives every month, covers the bills, and you never have to sell shares.

Start with what you already have coming in. A pension, planned part-time work, rental income. That's your starting floor. Then look at what your expenses will actually be. The difference between the two is the gap you need to fill.

Here's an example. Expenses run about $60,000 a year and you have a seven-year gap before you claim. That's a $420,000 expense gap. Subtract a small pension of $12,000 a year, which is $84,000 over seven years. Then add part-time consulting at $15,000 a year for three years, another $45,000. You're left with just under $300,000 across the seven years, or roughly $41,000 a year.

Step two is building the stream that produces that $41,000. Instead of dropping $300,000 into a bond fund and calling it done, you put together income sources that pay every month regardless of what the stock market is doing. Bonds still work here and they're the lowest paying option. Treasuries pay around 4%. Corporate bonds from companies like Apple, Johnson & Johnson, and Google run closer to 5 to 5.5%. Most annuities cost you access to your capital forever, but a multi-year guaranteed annuity works more like a CD or a bond, and five- and seven-year lock-up periods are paying closer to 5% right now.

Dividend ETFs are an option with the caveat that prices move every day and yields tend to get cut substantially in a downturn. Rental property tends to cash flow, and it comes with the job of being a landlord. There's also an asset called secured mortgage notes, where you act more like the bank on a piece of real estate. You lend against the property, you hold a recorded lien, and you receive monthly payments without being the landlord. Pick a mix of these so you're diversified.

Step three is to leave the rest alone. Once the floor covers your expenses, the remaining portfolio stays in equities and you don't touch it. It can go through a downturn and you're not selling into it. You let it recover.

What this does to your health insurance bill

The ACA marketplace draws a hard line at 400% of the poverty level. In 2026 that's $62,600 for a single person and $84,600 for a married couple. Below the line you qualify for subsidies that bring premiums down to around 8 to 10% of your annual income. Above it by $1 and the subsidies disappear completely. For a couple in their early 60s, unsubsidized premiums can run $1,500 to $2,000 a month, around $24,000 a year.

Every dollar you pull out of a traditional 401(k) counts as ordinary income, so selling shares to pay the bills is what pushes you over. Not every dollar of income counts the same way. Return of principal on a bond ladder, interest payments spread over multiple years, qualified dividends, and Roth distributions all show up differently in the modified adjusted gross income calculation the ACA uses. That lets you structure your withdrawals so your income lands under the cliff. Keeping the subsidy can save $15,000 to $20,000 a year, or $75,000 to $100,000 over a five-year bridge, purely because of how the income was structured.

The Roth window opens at the same time

For most retirees the traditional 401(k) is the biggest line item in the portfolio. Every dollar in there gets taxed as ordinary income when you take it out, or when required minimum distributions start at 73. The bridge years are the best chance you'll get to move that money out, with no wages coming in and Social Security not started yet.

If your portfolio income is already sitting under the ACA cliff, that puts you in the 12% bracket. In 2026 that bracket runs to $50,400 for a single person and $100,800 for a married couple, and above that you're at 22%. So you convert traditional 401(k) money into a Roth at 12 cents on the dollar instead of 22. For a couple that can mean $40,000 to $80,000 a year converted. Once it's in the Roth it compounds, never gets taxed again, and never faces RMDs.

The catch is that a conversion adds to your modified adjusted gross income and can trigger the ACA cliff, so you have to size it. Knowing your income floor is what makes the sizing simple. You know what your income is, you know where the cliff sits, and you fill the space between them with the conversion.

After Social Security starts, the glide path flips

Target date funds drift toward more bonds and less stock over time. At 65 you might be at 30% equities and 70% bonds, and by 75 you're down to 20% equities. That sounds like taking less risk as you age. For someone with an income floor it works the other way. Once Social Security is paying and the floor is in place, your bills are covered and the rest of the portfolio isn't needed for expenses.

The risk you were defending against in the bridge years was sequence of returns: a big downturn forcing you to sell a larger slice of the portfolio to pay the bills, leaving fewer shares to participate in the recovery. With expenses covered, that risk is off the table.

Wade Pfau and Michael Kitces published a paper on this in 2014 and called it the Rising Equity Glide Path. They found that starting at 30% stocks and gradually moving up to 70% over time outperformed the static 60/40 portfolio in almost every instance they modeled, including years with poor sequence of returns. While you're working and a paycheck is coming in, the portfolio can be mostly equities, and that's already what most people do. In the bridge years you need something replacing that paycheck, and that's the income floor. Once Social Security kicks in, you can move part of that floor back into equities.

Build it before you need it

One subscriber shared what he and his wife did to make this work. They started shifting their portfolio into dividend-producing investments around age 50, and when they retired in their late 50s they had that dividend income plus public sector pensions. Between the two, their expenses were covered. After Social Security started, some months left dividends over, and they'd add to their positions and increase the dividends further. They've been retired for nearly 15 years on that structure.

The part worth copying is the timing. You don't want to build your income floor the day you retire. You want it built five to ten years before that date. Every dollar you reallocate now into something that produces income is a dollar you don't have to reallocate in the middle of a market downturn six years from now.
