SYDNEY - Romantics looking for everlasting love will swoon over a new love equation released just in time for Valentine's Day and which can calculate the right age to fall in love.

The equation nicknamed the "Fiancee Formula" was created by an Australian mathematics professor and works by factoring in the age at which you start looking for a long-term partner and the absolute oldest age you would consider getting married.

"Although probability isn't the most romantic basis for a marriage, the formula does seem to fit a lot of couples -- whether through accident or design," said the equation's creator, Professor Tony Dooley at the University of New South Wales.

"There's no reason why the science can't be extended to calculate the best moment to marry," Dooley said in a statement.

However, love birds take note, the mathematical equation for love only has a 37% success rate.

The formula is helpful as a guide for the right moment to start getting serious, but could also be used by nervous men to calculate when to avoid the ultimate commitment, said Dooley.

**The formula**

According to a handout by the UNSW School of Mathematics and Statistics, the process for determining whether to ask someone to marry you goes as follows:

1. First of all, set out the last possible age by which you want to get married, for example, 39. Call this number n.

2. Then, decide the earliest age at which you.ll start to consider women as potential wife material, for example, from when you turn 20 onwards. This age becomes p.

3. Subtract p from n (i.e 39- 20), then multiply the result by 0.368. This gives you 6.992, which then needs to be added back to your minimum age (20), which more or less equals 27.

4. This result is your optimal proposal age. Ideally you should not propose to anyone before you hit this age, but afterwards you should prepare to pop the question to the very next girl you date – as long as she.s the best of the bunch so far.

The table below presents a number of solutions to the above:
