How to Build a Retirement Income Plan That Lasts

Most retirees enter retirement with a combination of guaranteed income sources — Social Security, perhaps a pension — and a portfolio of savings. The gap between what those guaranteed sources provide and what you actually need to spend is what your portfolio must fill.

For many couples, that gap is larger than expected. Social Security may replace 30–40% of pre-retirement income. If your lifestyle requires 70–80% replacement, the remaining 30–40% must come from your portfolio — every year, for potentially 30 years, through market cycles, inflation, and changing spending needs.

Understanding the size and nature of your income gap is the starting point for any serious retirement income plan. It determines how much you need to draw, how your portfolio needs to be structured, and how much risk you can afford to take.

One of the most effective frameworks for retirement income planning is the bucket strategy — dividing your portfolio into segments based on when you'll need the money. A near-term bucket (years 1–3) holds cash and short-term bonds to fund immediate expenses without selling growth assets. A mid-term bucket (years 4–10) holds more moderate investments. A long-term bucket holds growth assets designed to outpace inflation over a decade or more.

The bucket approach provides psychological clarity — you know your near-term expenses are funded regardless of what the market does — while keeping long-term assets invested for growth. It also provides a systematic framework for rebalancing and refilling buckets over time.

The specific allocation within each bucket depends on your income gap, risk tolerance, time horizon, and other income sources. There's no universal formula — but the framework itself is a powerful organizing principle.

The order in which you draw from different account types — taxable brokerage accounts, traditional IRAs and 401(k)s, Roth accounts — can have a significant impact on your lifetime tax burden and portfolio longevity.

A common approach is to draw from taxable accounts first, then traditional tax-deferred accounts, then Roth accounts last — allowing tax-free Roth assets to compound as long as possible. But this isn't always optimal. In years with low income, it may make sense to do partial Roth conversions to fill lower tax brackets, reducing future RMDs and their associated tax burden.

Withdrawal sequencing is one of the most technically complex aspects of retirement income planning — and one of the areas where professional guidance can add the most measurable value.

Taxes in retirement are often higher than retirees expect. Required Minimum Distributions from traditional IRAs and 401(k)s can push you into higher brackets. Social Security benefits become partially taxable once income exceeds certain thresholds. Medicare IRMAA surcharges kick in at higher income levels, adding hundreds of dollars per month to premiums.

A tax-efficient distribution strategy coordinates all of these factors — managing income levels to minimize bracket exposure, timing Roth conversions strategically, harvesting capital losses when available, and coordinating charitable giving with RMDs through Qualified Charitable Distributions (QCDs).

The goal isn't to minimize taxes in any single year — it's to minimize lifetime taxes across a 25–30 year retirement. That requires a long-term perspective and regular recalibration as tax laws and personal circumstances change.

A retirement income plan built at 65 will need to be revisited at 70, 75, and beyond. Spending patterns change — many retirees spend more in their early active years and less in their mid-70s, before healthcare costs drive spending back up in their 80s. Market performance, tax law changes, and family circumstances all require ongoing adjustment.

The couples who navigate retirement most successfully tend to treat their income plan as a living document — reviewed annually, adjusted as needed, and always connected to a clear picture of where they stand and where they're headed.
