How Forj\'s Compatibility Algorithm Works — Behind the Score

When you see a compatibility score on Forj, you are looking at the output of a system that processes dozens of data points across four weighted categories. The score is not arbitrary. It is not astrology. It is a structured attempt to predict whether two ambitious professionals have what it takes to build something lasting.

This article explains exactly what goes into that 0–100% number. Not the marketing version. The actual mechanics, the weights, the assumptions, and the limitations. We believe you deserve transparency about how we match you.

Factor One: Interests and Values (40%)

The largest weight in our algorithm is shared interests and values. This includes lifestyle preferences, hobbies, religious orientation, political leanings, family importance, and social habits. We weight this heavily because our research consistently showed that shared values were the strongest predictor of long-term relationship satisfaction.

During our user interviews, we asked thirty-four Nigerian professionals what mattered most in a partner. The top response was not looks, money, or status. It was "someone who understands my values." A lawyer who prioritises family time and a doctor who prioritises career advancement might both be successful, but their relationship will strain if they have not agreed on what success means.

We assess this through a combination of explicit questions during onboarding and implicit signals from profile content and interaction patterns. The more complete your profile, the more accurately we can score this dimension.

Factor Two: Career Alignment (25%)

Forj is built for professionals, so career context matters. This factor includes industry, career level, work schedule, professional interests, ambition trajectory, and work-life balance preferences. We do not believe doctors should only date doctors. But we do believe that two people with radically different relationships to work will struggle to synchronise their lives.

A founder who works eighty-hour weeks and a teacher with structured holidays can absolutely work. But they need to have explicit conversations about availability, travel, and financial expectations. Our algorithm surfaces this alignment so those conversations happen sooner rather than later.

Career alignment also includes geographic and relocation factors. If one person is committed to Lagos and the other is applying for jobs in London, that is useful information to surface early. Learn more about how Forj matches professionals on our How It Works page.

Factor Three: Relationship Intent (20%)

This factor measures what you actually want. Are you looking for marriage? A long-term partnership? Something casual while you focus on your career? There are no wrong answers. But there are wrong matches. Pairing someone who wants marriage within two years with someone who is not sure they want to commit at all is a recipe for pain.

We assess intent through direct questions and by analysing how users engage with the platform. Someone who fills out their entire profile, completes verification, and responds thoughtfully to prompts is signalling serious intent. Someone who skips steps and swipes rapidly is signalling the opposite. Both are fine. They just should not match with each other.

Factor Four: Education and Background (15%)

This is the smallest weight, and intentionally so. Education and background provide useful context, but they are not destiny. Two people with identical degrees can be completely incompatible. Two people from wildly different backgrounds can build an extraordinary partnership.

We include this factor because shared educational context can be a useful signal for communication style, social reference points, and family expectations. But we keep the weight modest to avoid creating an elitist matching environment. Your degree does not determine your worth as a partner.

How the Score Is Calculated

For each factor, we compare your responses and signals with the other person's responses and signals. We then normalise the comparison to a 0–100 scale. The overall score is a weighted average of the four factor scores using the percentages above.

A score of 85% means strong alignment across most dimensions. A score of 45% means significant misalignment. Neither score guarantees success or failure. What the score does is give you a starting point for evaluation. It tells you where to dig deeper.

What We Learned from User Interviews

We conducted over thirty in-depth interviews with Nigerian professionals during the development of this algorithm. The most consistent feedback was that people wanted transparency. They did not want to be told they were compatible without understanding why. They wanted to see the factors and make their own judgment.

We also learned that professionals are sceptical of dating app algorithms. They have been burned by platforms that prioritise engagement over outcomes. Our response was to build a system that is explainable. Every factor in your score is something you can understand and evaluate for yourself.

Limitations and Honesty

No algorithm can predict love. Compatibility scores are probabilistic, not deterministic. Two people with a 95% score might meet and feel nothing. Two people with a 60% score might discover an unexpected connection that the algorithm missed. The score is a tool, not a verdict.

We also know that people change. The person you are today is not the person you will be in five years. The algorithm scores current alignment, not future potential. Relationships require flexibility, compromise, and growth. No score can replace the work of actually building something together.

What we believe is that starting with alignment increases your odds. Forj Premium unlocks full compatibility insights, including breakdowns by factor and advanced filtering. It is designed for people who take their love life as seriously as their career.
