You’d be amazed how many couples sit down with me to plan their retirement and realize — sometimes for the first time — that they aren’t on the same page about Social Security. One of them wants to wait until 70 for the biggest check possible. The other wants the money now. And neither of them has really thought through what happens to the surviving spouse when one of them is gone. This conversation happens in my office more than almost any other, and it never gets old, because the stakes are always real.

That’s exactly where Tom and Susan found themselves when they came to me recently to build their retirement financial plan. Tom had been thinking about this for years. He’d watched our videos, done his homework, and arrived with a clear position: he was going to wait until 70 to collect his maximum Social Security benefit of $5,176 a month. It was a perfectly reasonable plan. For many people, it’s the right one. But retirement planning is rarely just about one person, and Susan had something to say about it.

The Spousal Benefit Surprise

When we pulled up Susan’s Social Security statement, she saw that her own benefit at full retirement age was $874 a month. She’d been a stay-at-home mom for most of her adult life, working only early in her career, so the number wasn’t shocking — but it stung a little. Then we told her something that changed her entire outlook: she was eligible for a spousal benefit worth roughly half of what Tom would receive. Suddenly, instead of $874 a month, she was looking at closer to $2,000 a month. That felt a lot more like an equal contribution to the household.

There was one catch. She couldn’t collect that spousal benefit until Tom filed for his own. And Tom wasn’t planning to file for another two years.

Susan made her feelings known.

Running the Numbers

At that point, our job as financial planners was to do what we always do — take the emotion out of it long enough to run the numbers, and then put the emotion back in where it belongs. We looked at what it would mean for Tom to file at 68 instead of 70. His monthly check would drop from $5,176 to roughly $4,298, a difference of nearly $900 a month for the rest of his life. That’s not a small number. But here’s the other side of that: by filing two years earlier, he’d collect over $100,000 in Social Security income he otherwise would have left on the table.

We then looked at the break-even point — the age at which waiting until 70 would have paid off more in total lifetime benefits than filing at 68. That number was 84. If Tom lives past 84, waiting would have been the better financial move. If he doesn’t, filing earlier wins. Nobody knows which side of that line they’ll land on, but knowing where the line is changes the conversation considerably. When Tom saw that number, he started to soften.

It’s Not Just About the Math

Here’s something I’ve learned after decades of doing this work: a financial plan that makes perfect sense on paper but causes stress, conflict, or resentment in a marriage isn’t actually a good plan. The numbers have to work, yes. But so does the life you’re building around them.

In Tom and Susan’s case, the decision to file at 68 instead of 70 didn’t significantly damage their long-term financial picture. They have other assets. They have a solid plan. Taking Social Security two years early wasn’t going to leave them struggling later in life. And so, when we weighed the modest financial trade-off against Susan’s very clear preference and Tom’s own growing comfort with the idea, the path forward became obvious. They filed when Tom retired, Susan received her full spousal benefit right away, and they started retirement with over $76,000 in projected annual Social Security income from day one.

Happy wife, happy life. And in this case, it also happened to be sound financial planning.

The Estate Planning Piece Nobody Talks About

There’s one more dimension to this decision that too many couples overlook entirely, and I want to make sure you don’t. When one spouse passes away, the survivor doesn’t keep both checks. They keep the larger one. The smaller check stops. This means that whoever has the higher benefit — almost always the husband, in couples of Tom and Susan’s generation — carries an enormous responsibility in how they time their filing.

If Tom had waited until 70, filed, and then passed away at 78, Susan would have inherited his larger check and been better protected for the rest of her life. That’s the traditional argument for waiting, and it’s a legitimate one. But in their situation, what drove the estate planning conversation wasn’t the size of Tom’s check — it was the size of Susan’s spousal benefit. Getting her to $2,000 a month instead of $874 a month became the priority, and that required Tom to file. Once he did, her spousal benefit was locked in, and it will be there for her as long as she lives.

Every couple’s situation is different. For some, the right answer really is to wait until 70, especially when one spouse is significantly younger, when health is good, or when there aren’t other assets to draw on in the meantime. But the decision should never be made in a vacuum, and it should never be made without understanding all of the pieces — the spousal benefit, the survivor benefit, the tax implications, and yes, what both people actually want.

Making the Decision With Full Clarity

What I want for every person who watches our videos or sits down with us for a financial plan is simple: I want you to make this decision knowing exactly what you’re choosing and exactly what you’re giving up. Social Security is one of the only truly irreversible decisions in retirement planning. Once you file, that’s it. You don’t get a do-over.

Tom and Susan made their decision with full information, full clarity, and full agreement. That’s the goal every time. If you’re approaching this decision yourself and you’re not sure where to start, I’d encourage you to watch Episode 2 of our Financial Planning series, where we walk through Tom and Susan’s story in detail, including the actual numbers, the software projections, and the conversation that brought them to their final decision.
