You’ve probably heard the old saying about the "seven-year itch." It sounds like a bit of Hollywood fluff from a 1950s Marilyn Monroe movie, but honestly? The data says it's pretty much spot on. If you look at the divorce rate by years of marriage, there is a very real, very measurable spike that happens right around that seven-to-eight-year mark.
Marriage is a weird journey. One year you're picking out curtains and arguing over where the toaster goes, and the next thing you know, a decade has vanished. But those years aren't created equal when it comes to risk.
In 2026, the way we look at marital longevity has shifted. We aren't seeing the same "divorce revolution" patterns of the 1970s. Instead, we’re seeing a landscape where people marry later, wait longer, and—surprisingly—stay together more than their parents did. But even with these modern shifts, the "danger zones" for a marriage remain remarkably consistent.
The High-Risk Zones: When Most Couples Call It Quits
Statistically, if you can make it past the first decade, your odds of staying married for life skyrocket. But getting there is the hard part. The divorce rate by years of marriage typically follows a bell curve that peaks early and tapers off into a long, thin tail.
The "Starter" Phase (Years 1–2)
A significant chunk of divorces happens almost immediately. We're talking about couples who realize within 24 months that they’ve made a massive mistake. Often, this is down to "unrealistic expectations." Basically, the wedding was great, but the marriage is a disaster.
Data from the CDC and recent 2025-2026 surveys suggest that about 16% of all divorces occur within the first five years. It’s a period of "shock to the system" where the reality of shared finances and domestic life hits home.

The Danger Peak (Years 7–8)
This is the "Seven-Year Itch" in the flesh. According to the Census Bureau and the American Community Survey (ACS), the median duration for a first marriage that ends in divorce is roughly 7.8 years for men and 7.9 years for women.
Why then?
- The Routine Trap: By year seven, the "new car smell" of the relationship is gone.
- The Childcare Crunch: Many couples are deep in the weeds with young children, leading to sleep deprivation and "roommate syndrome."
- The Identity Crisis: People change. Who you were at 28 isn't who you are at 35.
Why the 10-Year Mark is the Magic Number
If you hit your 10th anniversary, take a breath. You've officially entered what researchers call the "stability window."
Recent studies from the Institute for Family Studies (IFS) show that for marriages formed in the 2010s, only about 18-19% ended in divorce by the 10-year mark. Compare that to the 1970s, where 30% of couples had already split by year ten. We are getting better at this.
Once you pass 10 years, the annual risk of divorce begins to drop every single year. By the time you reach year 15, the rate levels out. It’s like the relationship has "hardened." You've survived the job losses, the toddler years, and the awkward in-law phases. You’ve built a shared history that becomes harder (and more expensive) to untangle.

The Rise of "Gray Divorce" (Years 20+)
While young people are keeping it together more, there is one group bucking the trend: the Boomers.
"Gray divorce" refers to couples splitting after 20, 30, or even 40 years of marriage. Since the 1990s, the divorce rate for people over 50 has doubled, and for those over 65, it has tripled.
Imagine being married for 25 years. The kids are gone. You look across the breakfast table and realize you have nothing left to say to this person. In 2026, the stigma of being a 65-year-old divorcee is basically gone. People are living longer and thinking, "I have 20 good years left; do I want to spend them like this?"
About 22% of all divorces now happen after 25 years of marriage. It’s a massive shift that proves the divorce rate by years of marriage isn't just about the early struggles anymore.
Does It Get Harder the Second Time Around?
Honestly, yes. The stats for remarriage are... not great.

- First Marriages: ~41% end in divorce.
- Second Marriages: ~60-67% end in divorce.
- Third Marriages: ~73% end in divorce.
The "years of marriage" timeline moves even faster in second marriages. The median duration drops from nearly 8 years down to about 7 years. You’re often dealing with "blended family" stress, child support issues, and the simple fact that you already know you can survive a divorce. The "exit door" is easier to find the second time.
Factors That Actually Change Your Odds
It’s not just about the calendar. Certain "protective factors" can drastically lower your specific risk regardless of what year you’re in.
- Education: If you have a college degree, your risk of divorce is about 25% lower than someone with a high school diploma.
- Age at Marriage: Marrying after age 25 reduces your divorce risk by 24%. Those "teen marriages" we see in movies? They have the highest failure rates in the first five years.
- Income: Financial stress is the #1 marriage killer. Couples with higher assets and no debt are significantly more stable.
Actionable Insights: Navigating Your Years
If you're looking at these numbers and sweating, don't. Statistics aren't destiny. They’re just patterns.
If you’re in Years 1–3: Focus on "role clarity." Talk about the boring stuff—money, chores, and how often the in-laws visit. Most early divorces happen because of unexpressed expectations.
If you’re in Years 7–8: Watch out for the "itch." This is the time to prioritize intimacy over routine. It’s the highest-risk period for infidelity because people feel "stuck."
If you’re in Years 20+: Re-evaluate your shared goals. If the "glue" holding you together was the children, you need to find a new reason to stay once they leave the nest.
Your Next Steps:
- Audit your "roommate" status: If you haven't had a non-logistical conversation in a week, you're in the danger zone.
- Check the "10-year" horizon: If you're approaching a decade, look at your long-term financial and legal alignment.
- Look into "Gray Divorce" planning: If you are in a long-term marriage that is struggling, consult a financial advisor specifically about retirement assets, as these are the biggest hurdles in late-life splits.
