About This Calculator
The Dating Theory Calculator applies the famous optimal stopping problem (also known as the secretary problem, 37% rule, or marriage problem) to help you maximize your chances of finding the best romantic partner. Dating is often described as a numbers game — with swipes, matches, and first dates, how do you know when to stop looking and commit? Mathematics has a surprisingly practical answer.
The formula works like this: if you plan to date n people in your lifetime, the optimal strategy is to reject the first n/e ≈ 37% of them no matter how good they seem. This is your exploration phase. After that, commit to the very next person who is better than everyone you have met before. This gives you the highest possible probability of selecting your best match — about 37% with the standard model, and much higher if you are open to one of the top few candidates rather than demanding the absolute best.
The calculator extends the classic model with two important real-world options. First, you can settle for one of the top 5 or top 10 matches instead of demanding the single best partner — this dramatically boosts your success probability. Second, you can factor in the chance of rejection (0% to 50%) because dating is a two-way street and your chosen partner may not feel the same way.
Regional notes: The optimal stopping theory is a universal mathematical principle that applies regardless of geographic region. Whether you are dating in New York, London, Mumbai, or Tokyo, the 37% rule provides the same statistical advantage. Cultural differences in dating norms — arranged vs. love marriages, typical relationship timelines, or family involvement — do not change the underlying mathematics of sequential decision-making under uncertainty. If you are in a culture with arranged introductions, consider each potential match as one observation in the sequence.
Frequently Asked Questions
What is the optimal stopping theory in dating?
The optimal stopping theory (also called the secretary problem or 37% rule) suggests you should date and reject a certain number of people first to gather data, then commit to the next person who is better than everyone you have met before. This mathematical strategy maximizes your probability of finding the best partner.
What is the 37% rule in dating?
The 37% rule advises that you should spend the first 37% of your dating period (or reject roughly 37% of potential partners) evaluating candidates, then commit to the next person who surpasses all previous ones. This is derived from the mathematical constant 1/e ≈ 36.79%.
How does the dating theory calculator work?
Enter the total number of dates you are willing to go on, choose whether you want the best partner or one of the top matches, and optionally factor in rejection risk. The calculator uses the optimal stopping formula to determine how many dates to reject first and what your probability of success is.
What are the risks of the optimal stopping strategy?
The main risk is that your ideal partner might be among the first group you reject (roughly 37%), which means you will end up alone. Another risk is that early terrible dates lower your standards, causing you to settle too early. The strategy maximizes probability but does not guarantee success.
Can the dating theory calculator account for rejection?
Yes. You can set the chance of being rejected from 0% to 50%. The calculator adjusts the success probability downward using a geometric series model, accounting for the possibility that your chosen partner may not feel the same way.
Is the 37% rule proven by research?
Yes. Experimental psychologists J. Neil Bearden and Amnon Rapoport studied decision behavior in sequential selection problems. Their research showed people tend to stop searching too early compared to the optimal policy, confirming that the mathematical model provides a useful benchmark even if humans deviate from it emotionally.
How many people should I date before settling down?
According to the optimal stopping theory, you should reject the first 37% of your total estimated dating pool, then pick the next person who is better than everyone before. For example, if you estimate you will date 50 people, reject the first 18-19, then commit to the next person who exceeds all previous ones.
What is the secretary problem?
The secretary problem (also known as the sultan's dowry problem or marriage problem) is a famous optimal stopping puzzle. You interview n candidates in random order and must decide on the spot whether to hire each one. The optimal strategy is to reject the first n/e candidates, then hire the next one better than all previous.
