This score is based on demographic and behavioral research on divorce predictors. It is a statistical estimate, not a prediction for any individual couple. Couples counseling, financial planning, and communication skills training can significantly reduce risk regardless of demographic factors.

Research note: The three most predictive factors for divorce are: high conflict frequency, financial stress, and poor communication. These are also the most modifiable with counseling and financial planning.

This model uses 15 research-validated factors. Substance abuse issues carry the highest individual risk (+18 to +30 points). Couples therapy and financial counseling are the most effective interventions — addressing the top 3 risk factors can reduce score by 30–40 points.
How the Divorce Risk Calculator Works
This calculator uses demographic and behavioral research on divorce predictors to generate a statistical risk score. It draws on data from sociological studies including the work of researchers at the National Center for Family and Marriage Research, the American Psychological Association, and longitudinal marriage studies tracking thousands of couples over decades.
The score represents a statistical probability estimate based on known risk factors — it is not a prediction for any individual couple. Many couples beat the odds through commitment, communication, and professional support. The financial impact tab shows what divorce would realistically cost if it did occur, providing a powerful incentive for relationship investment.
Research-Based Risk Factors
Key Divorce Risk Factors (research-backed):
Increases risk:
- Age at marriage under 25: +10 to +25 points
- Prior divorce (one spouse): +15 points
- Prior divorce (both): +25 points
- High conflict level: +20 points
- High financial stress: +15 points
- Large income gap (75%+): +12 points
- Very different education levels: +8 points
- Cohabitation before marriage: +5 points (debated)
Decreases risk:
- Marriage length 15+ years: −10 points
- Children together: −8 points
- High religious involvement: −10 points
- Low conflict level: −8 points
- Low financial stress: −5 points
- Similar education levels: −3 points
US Baseline: ~42% lifetime divorce rate (2025 estimate)

Even for high-risk couples, intervention significantly improves outcomes. Research by Dr. John Gottman found that couples who learned to repair conflicts and maintain a 5:1 positive-to-negative interaction ratio had an 83% success rate in maintaining marriages over 9 years.
Frequently Asked Questions
The oft-cited "50% divorce rate" is a statistical artifact of dividing annual divorces by annual marriages — a misleading calculation. The actual lifetime probability of a first marriage ending in divorce for Americans is approximately 40–45%, and has been declining since the 1980s peak. College-educated couples who marry after age 25 have lifetime divorce rates closer to 25–30%. Second marriages have higher rates (~67%), and third marriages higher still (~73%).
The research on pre-marital cohabitation is nuanced and has evolved. Earlier studies consistently found a "cohabitation effect" (higher divorce risk for couples who lived together first). More recent research suggests this effect has largely disappeared or reversed for couples who cohabit with a clear commitment to eventual marriage. "Sliding" into cohabitation without a commitment discussion still shows elevated risk. Today, about 70% of US couples cohabit before marriage, so the stigma-based risk factors from earlier decades no longer apply.
Research consistently identifies these as the strongest predictors: (1) High conflict and criticism/contempt (Dr. Gottman's "Four Horsemen": criticism, contempt, defensiveness, stonewalling); (2) Financial stress and conflict about money; (3) Young age at marriage (especially under 22); (4) Prior divorce in either spouse; (5) Infidelity; (6) Substance abuse or addiction; (7) Domestic violence. Protective factors include shared values, regular positive interactions, ability to repair conflicts, financial stability, and social support networks.
The average contested divorce costs $15,000–$30,000 per spouse in legal fees alone. High-conflict divorces with custody disputes and complex assets can exceed $100,000 per side. Uncontested divorces (where parties agree on all terms) can cost as little as $1,500–$5,000 total using mediation or online divorce services. Beyond legal costs, divorce typically reduces household income by 20–25% and depletes retirement savings by an average of 50%. The total financial impact — including reduced savings, two households, and support obligations — averages $50,000–$100,000+ per spouse.
Yes. Research shows that Emotionally Focused Therapy (EFT) achieves a 73% recovery rate for couples in distress and a 90% significant improvement rate. Gottman Method therapy and Behavioral Couples Therapy (BCT) both have strong evidence bases. Couples who seek therapy early (before patterns become entrenched) have far better outcomes than those who wait until the relationship is severely damaged. The average cost of couples therapy is $150–$300/session — a tiny fraction of divorce costs. Premarital counseling shows a 30% reduction in divorce risk.
