Some retirees do not see it coming until they are standing in the middle of it.
You retire. The paychecks stop. The bills don’t. And Social Security hasn’t started yet.
For many households, that window runs somewhere between one and four years, depending on when benefits are claimed. It’s a stretch of time that’s often neglected in the headline retirement math, and if it hasn’t been planned for, it can create strain even in a well-funded retirement.
We call it the income gap. It’s one of the more overlooked (and consequential) parts of a retirement plan.
Why Social Security Doesn’t Start When Retirement Does
There’s a common assumption that retirement and Social Security begin on the same day. They don’t.
Benefits begin when you elect to claim them, which may or may not line up with the day you stop working. Some people who retire in their early to mid-60s deliberately wait before claiming, because delaying can increase the monthly benefit received for the rest of their life.
That decision can make sense, but it creates a period where retirement has started, Social Security hasn’t, and the mortgage, the insurance premiums, and the grocery bill are all still arriving on schedule.
Why the Gap Years Carry Extra Weight
Here is what makes this window different from any other stretch of retirement.
The gap years often overlap with the early years of retirement, which are commonly viewed as among the more financially sensitive years in a plan. That is the sequence-of-returns risk window, a concept we refer to as “Bad Timing.” The order in which returns arrive matters, not just the average.
So two things are happening at once: you are drawing down your portfolio to cover living expenses, and you are doing it during the period when, depending on market conditions, a downturn could have a longer-lasting effect.
Pulling from the wrong accounts, in the wrong order, at the wrong time may work against a plan that looked solid on paper. Tax considerations and long-term strategy also influence which withdrawals make sense. Each household’s income sources and timing will differ.
A Hypothetical Example
Consider a retiree who stops working at 63 and plans to claim Social Security at 67. That is a four-year gap.
If that household needs $7,000 a month to cover expenses, and none of it is coming from Social Security yet, roughly $336,000 will need to come out of the portfolio over those four years.
If markets are flat or up during that stretch, that is manageable. If the portfolio drops 20 percent in year one, those same withdrawals are coming out of a smaller base, potentially locking in losses at an inconvenient moment.
This example assumes consistent withdrawals and does not reflect investment returns, taxes, fees, or other income sources. It is illustrative only.
Four Things We Work Through With Clients
The gap can introduce additional risk into a retirement plan, though the impact varies depending on how withdrawals are structured. Planning strategies may help manage that risk. That is why we treat it as its own piece of the plan rather than folding it into the general withdrawal conversation.
1. Map the Gap Before Retirement
Before a client receives their last paycheck, we sit down and put numbers on the gap.
How long will it last? How much income needs to be replaced each month? What sources are available, and which should be preserved for later?
This conversation works best two to three years before the retirement date, not the week after. Once the paycheck has stopped, the options narrow.
2. Build a Dedicated Source
Rather than relying on a single account to cover everything, one approach we commonly use is building a separate pool of assets specifically for the gap period.
That might be a combination of cash, short-term bonds, CDs, or an investment account positioned conservatively. This connects directly to the Three Pillars framework, where reserve assets serve a distinct purpose from investment income and guaranteed income.
The goal is to cover the gap without drawing down long-term growth assets during the years they may be most vulnerable to sequence-of-returns risk in certain market conditions.
3. Sequence Withdrawals Carefully
Not all accounts are created equal, and the order you pull from them can affect both your tax bill and the longevity of the portfolio.
In some cases, pulling from taxable accounts first, before required minimum distributions or Roth distributions begin, allows tax-deferred accounts to keep compounding. But every household is different. The optimal approach depends on tax brackets, future income expectations, and long-term planning goals.
This decision deserves careful modeling rather than a default setting.
4. Evaluate the Social Security Decision Rigorously
When to claim Social Security is one of the more consequential financial decisions a retiree makes.
Based on current Social Security rules, and depending on your full retirement age, claiming at 62 versus waiting until 70 can mean a difference of roughly 75 percent or more in the monthly benefit.
For a couple, it gets more complex, because survivor benefits are tied to the higher earner’s claiming decision. The optimal strategy depends on individual factors, including longevity expectations, income needs, and spousal considerations.
We model this as part of a retirement income plan, not as an afterthought.
A Long-Term Plan Is Not a Near-Term Income Plan
We often see people enter retirement with a strong long-term plan and no near-term income plan.
The portfolio is diversified. The target withdrawal rate is known. What is missing is the month-by-month picture of where the money is coming from for the first three years.
For some retirees, the difficulty is not a market downturn or a poor investment selection; it’s the absence of a bridge plan for a window they knew was coming.
The families we work with who navigate the income gap well tend to share one thing: they planned for it in advance rather than working it out after the paycheck stopped. Planning ahead does not eliminate risk, and results will vary based on market conditions, spending needs, and individual circumstances. But it addresses the window before it arrives rather than during it.
When to Start This Conversation
If you’re within five years of retirement, we recommend addressing the income gap now.
Mapping it early may allow for greater flexibility in structuring a bridge designed to help manage risk in the portfolio, and it gives you a clearer picture of what your income could look like in years one, two, and three. Outcomes will vary based on individual circumstances, market conditions, and planning assumptions.

Frequently Asked Questions
What is the retirement income gap?
It’s the period between your last paycheck and your first Social Security check. Retirement has started, but benefits haven’t, and expenses continue on schedule. For many households, that window runs somewhere between one and four years, depending on when benefits are claimed.
How long does the income gap last?
It depends on the distance between your retirement date and your Social Security claiming age. Someone who retires at 63 and claims at 67 has a four-year gap. Someone who retires at 65 and claims at 66 has a one-year gap. The claiming decision is what sets the length.
Why doesn’t Social Security start automatically when I retire?
Benefits begin when you elect to claim them, not when you stop working. The two dates are independent. Some people who retire in their early to mid-60s deliberately wait before claiming, because delaying can increase the monthly benefit received for the rest of their life.
When should I start planning for the income gap?
The conversation works best two to three years before your retirement date, not the week after. If you’re within five years of retirement, it’s a good idea to map out now. Once the paycheck has stopped, the options narrow.
