Drake Equation for Love Calculator
Are we truly alone in the universe? Most importantly, will you be alone on Valentine's day?
Just two days after Super Bowl LVII you'll either be alone or with your partner during Valentine's day to celebrate or mourn that receiver dropping that last-second catch.
If you're wondering whether you'll be able to find a partner in time for it, boy, do we have the tool for you.
💡 According to the U.S. Census Bureau, 46.4% of U.S. adults are single. That is 117.6 million Americans!
Based on research written by Peter Backus, an economist at the University of Warwick, our Drake Equation for Love Calculator will tell you exactly how likely you are to find your significant other, taking inputs such as your age, gender, and location.
While this research seems like it came straight from an episode of The Big Bang Theory, it uses the same equation.
Without further ado, let's begin looking for your potential partners!
The Drake equation for love calculator
First, let's show you how to use our calculator and get your result. In the next section, we'll dig into the maths behind the calculator.
The calculator is really easy to use — just answer a few questions about yourself and your ideal partner, and it will work out how many matches are out there and your chances of finding them. Let's go through the calculator and get your results.
Location 🏙️ — Select the state where you live or one near you. This defines the pool of people the calculator will select from. If you are not near one of the listed states, choose the "All US states" option instead, or use the
advanced mode(see below for details).
Your attractiveness — Rate your attractiveness on a scale of 1 to 5 (5 being very attractive). It's best to be honest when answering this question. If unsure, ask a good and honest friend or a stranger at the nearest coffee shop.
Social skills — Say how well you get on with other people on a scale of 1 (difficult) to 5 (very easy). Again, be honest and seek the opinion of those around you.
What are you looking for in a partner?
- Gender ♂♀ — Are you looking for a boyfriend or a girlfriend? You can also say you don't mind which gender.
- Minimum age — What is the minimum age of a partner that would be a good fit for you?
- Maximum age — What is the maximum age of a person you are looking for?
- University educated 🎓 — Should the person you're looking for have a degree or not? You can also say you don't mind either way.
- Attractiveness of people — Thinking about people that match your preferences so far, what proportion do you find attractive? Select one of the three existing options, or select "Custom value" to enter this factor as a percentage.
Once you've entered all the calculator inputs, it will show you the number of potential partners that are out there. It also tells you the percentage chance of finding love based on the number of people in your chosen state or the whole of the US. For a bit of fun, we compare your chances with the existence of an alien civilization within 1000 light-years of Earth. 👽
For those who want to specify your own factors to use in the Drake equation for love, click on the
advanced mode button. Doing this displays the following inputs:
- Total population — This is the base population figure that the calculator uses. You could change this value to reflect the population of a different country or region.
- Gender — The decimal fraction of the population who is the gender you are looking for.
- Location — The faction of the population of the correct gender who live near you.
- Age — The proportion of these people who are age-appropriate for you.
- University degree — The proportion of these people with a university degree. If you don't mind about this option, enter 1.
- Single rate — The fraction of these people who are single and ready to mingle.
Once you have filled in all of these fields, the calculator will display the results using these inputs. Note that this result still takes into account your answers for your attractiveness, social skills, and your perceived attractiveness toward people.
To switch back to basing the results on the standard mode of the calculator, remove one of the advanced inputs.
💡 If you have changed the gender or location factors, you'll need to re-select these options.
Finding love and aliens with maths
The original Drake equation (as formulated by the British astronomer Dr. Frank Drake in 1961) uses Bayesian probability to calculate the number of alien civilizations in our galaxy with whom we could communicate. It famously states:
The result of this equation, , is the number of contactable alien civilizations in our galaxy. The other values represent increasingly specific conditions (like , the fraction of Earth-like planets that develop some form of life). This way, the number of alien civilizations that ought to exist is narrowed down.
Using his formula, Dr. Drake estimated that 10,000 alien civilizations may exist in our galaxy alone. While that sounds like an exciting number, there are more than 200 billion stars in our Milky Way. So, the odds of pointing your telescope at a random star and seeing E.T. wave back at you is around 0.000005%. And that's if Dr. Drake's parameter estimates were even correct.
Is love more rare than aliens?
Many years after Dr. Drake's equation became famous, Peter Backus realized that a girlfriend might just be even rarer than an alien civilization. Using the mathematical principles behind the Drake equation, Backus estimated the size of his dating pool and published his findings in. His girlfriend-finding equation is:
Each variable whittles away at the population based on Backus's criteria for a life partner — with the same maths as the Drake equation. The variables in the equation are:
Your number of potential partners.
The fraction of the population who are the appropriate gender.
The fraction of men/women (as per your preference) living in your state.
The fraction of men/women in your state who are in your preferred age range.
The fraction of age-appropriate men/women in your state with a university education (optional).
The fraction of university-educated, age-appropriate men/women in your state who you find physically attractive.
❓ Have you ever wondered what your age is in days, minutes, or even seconds? Check the chronological age calculator to find out!
By looking at data for the empirical parameters and estimating the rest, Backus found that 10,510 people meet his criteria. You might think it doesn't sound too bad — until he realized he didn't account for whether these people find him attractive, whether they are single, and whether they'd get along.
After multiplying these extra fractions (, , and respectively) at the end of his equation for love, the number of potential girlfriends dropped down to 26. In the whole of London. "Not great," as he had put it himself.
💡 Dr. Drake (who is still alive today) has yet to make any comments on Backus's adaptation of his work.

Love is out there — just ask Peter
As he was so disheartened to find out, Backus's odds of finding a girlfriend were extremely low. And yet, a mere three years after publishing his paper, Backus got married to a friend of a friend he met at a dinner party. One of his 26 viable partners was only two degrees of separation away!
Girlfriends (unlike aliens) aren't science fiction. We don't know whether Backus's wife, Rose matches all his criteria, but one thing is sure: if this pessimistic mathematician can find love against the odds he calculated himself, then so can you!
Love can be anywhere, and more people find it every day. There were.
Mathematical tips for finding love
There are plenty of ways to beat the odds presented by the Drake equation for love,.
🙋 "Keep looking and spend a lot of time hanging out in places where other people who satisfy your criteria hang out. Go to bars, go to music shows, go to places where people hang out, and increase the probability. That's what the equation shows." — Peter Backus
In response to the bleak outlook of Backus's paper, love gurus and mathematicians alike shared their tips to find love:
Relax your criteria. Based on her statistical studies, from his original 5% to 20%), he would increase his original estimate from 26 to 832.in the equation when he reached his conclusion. She claims that if Backus was less picky (e.g., if he increased
Dr. Fry had also found that the happiest and longest-lasting marriages are ones with "low negativity thresholds" — where conflict and anger subside quickly. For this reason, the mathematicianand eliminate any that are easy to anger or argumentative. Perhaps bring up the latest about Boris?
Put yourself out there. As Backus suggested, the more you expose yourself to the dating world, the greater your chances of meeting someone you can grow old with. It's just statistics — and common sense. And while Tinder has its hidden algorithms, there's no mathematical way to predict who you'll click with — you just have to take the plunge and go looking for someone yourself.
💡 Backus and his peers presumably have no tips for finding aliens, though.
