Women Fertility Score Calculator

Women Fertility Score Calculator

Determining the fertility of a woman is a complex task and that is because a lot of factors are involved.

Some of these factors are available in variable conditions, for example, it is said that the prime age for fertility is 18 – 24. Based on this, a girl at 19 should expect to easily get pregnant, but that may not be the case if she had had multiple abortions.

Regardless of all the varying conditions and dependencies, this women fertility score calculator tries to aggregate all the common factors that largely affect the fertility of a woman.

The factors were gathered after going through several popular research documents that are available on the subject of women’s fertility.

The scores have no medical connection, they are just estimates. So someone may score 30% and still find it very easy to conceive, meanwhile, another score 70% and still experiences some challenges. The challenges might stem from the partner they are trying to conceive with or some other factors.

In essence, the scores derived from this calculator are not accurate predictions as to whether a woman will conceive or not.

So What does the Women Fertility Score Calculator do?

1. It helps you know the major factors that can affect your fertility.

The women fertility score calculator is more of an educational tool. It draws your attention to all you need to consider while getting ready to conceive. It is a tool that informs by attempting to score you.

2. The calculator tries to tell you what else you need to do

The Fertility Score Calculator has sections and each of the sections has a score. The Women Fertility Score Calculator helps a woman know what she needs to work on to get ready to conceive.

What the Women Fertility Score Calculator does not do

1. The Fertility Score calculator does not guarantee whether you will get pregnant or not.

2. The calculator’s score doesn’t determine whether a woman is barren or not

3. The calculator is not a medical tool and does not claim to be one. At worst, you can treat it as a Fertility Game for Fun. At best, treat it as a Fertility Educational tool.

Because of this, the scores from the calculator cannot be quoted as a medical report or diagnosis.

4. The calculator does not provide information that is not acquired from Medical experts.

In as much, as we do not guarantee its perfection, we made it as close to perfection as it can be.

FAQs about the Women Fertility Score Calculator

1. Is the Calculator accurate?

We tried our best to build the algorithm of the Women Fertility Score Calculator to closely predict fertility as much as we can, but we do not guarantee that it is always right. One of the reasons is the algorithm is built on resources provided by scientific studies which sometimes may not be entirely true. Theories that are held for a long time have many times been disproven.

The second reason is the various conditions that surround each human being. There are always exceptions, especially when it comes to the human body and its operations.

2. Was the Fertility Score Calculator made by Doctors?

Not it wasn’t!

But it was made from resources produced by doctors and medical experts. All of the factors considered are amply sourced and all the resources we used are listed at the bottom of this page.

3. Can I quote the scores from the calculator as a medical document?

Absolutely, No!

The Algorithm of the Women Fertility Score Calculator

The calculator has 3 major sections, namely –

  1. Age
  2. Weight & BMI
  3. Lifestyle

Each of the sections has a score calculated as a %.

The average of the three scores is calculated to arrive at the total score as a percentage.

So each section has 100% and the total score is the summation of the 3 scores in each section divided by 3.


Age is one of the major factors that affect pregnancy.

We assigned scores to each age based on the research information contributed by Pavna K. Brahma, M.D., FACOG on this website.

According to the research, women of age 20 – 24, have an 86% chance of conceiving in 12 months. Those in the age range of 25 to 29 years have a 78% chance of conceiving within a year, 25 to 29 years – 63%, and 35 to 39 years – 52% respectively.

If the woman is less than 20, the chance is set at 86%. At age 40 and above the chance reduces to 44% according to WebMD.

The scores may be lower in real life than what the calculator suggests, but we tried to stay within the limits of definitive research-backed data.

Note that this information about the percentage of chances at each age range is corroborated by other documents although not all of them maintain the exact same percentages. For example, Mutsaerts MA, Groen H, Huiting HG, Kuchenbecker WK, Sauer PJ, Land JA, Stolk RP, Hoek A claim that when a woman is over 36 years the chances of getting pregnant may only be 41%.

But we choose to stick with the fair number which is 44% (for 40 and above).

We have a calculator that determines women’s chances of pregnancy based on their age.

Weight & BMI

No need over flogging the fact that BMI has a direct impact on the chances of a woman getting pregnant.

While some sources claim that every unit of BMI above 29 reduces the chances of getting pregnant within one year by 4%, some other sources claim the reduction is by 5%. We chose to go with the latter.

So assuming that the chance of getting pregnant at a BMI of 18 -29 is 100, then a 5% reduction at every point will mean a chance of 95% at a BMI of 30.

A 2015 research involving 1,950 women showed that women who were underweight (with a BMI under 18.5) experienced a 25 percent longer waiting period for conception as compared to those whose weight was within the normal range. Our scores for BMIs less than 18 are based on this study.


This is a vital part of the Fertility Score Calculator and it has the most complicated algorithm.

This is because it involves 4 different parameters.

  1. Hours Spent Working
  2. Smoking of Cigarettes
  3. Drinking of Alcohol
  4. Ovulation/Menstrual Cycle

All of these factors contribute to the 100% score for this section.

Hours Spent Working

Research by Reuters shows that working more than 40 hours a week causes about 20 percent delay in getting pregnant, in comparison to women who worked for fewer hours.

Smoking of Cigarettes

According to the National Library of Medicine,

women who smoked between 0 to 10 cigarettes each day demonstrated a notably higher pregnancy rate (52.2%) in comparison to those who smoked 10 or more cigarettes per day (34.1%). These results indicate that a deteriorated uterine environment, which is caused by cigarette smoke, was the potential cause for the lower pregnancy rate in women who smoke.

The score for the Smoking of Cigarette was formed based on this data.

Drinking of Alcohol

Research shows that alcohol can decrease the probability of conception by over 50%.

You can find out more information about the research here.

Ovulation/Menstrual Cycle

Knowing your fertile window increases your chances of getting pregnant because you know the exact days to have sexual intercourse. Not knowing it reduces your chances. This is because ovulation occurs just within 24 hours monthly.

Now, away from the algorithm, would you like to know more about how each of the factors we have mentioned affects fertility, if yes, then read on.

How Age Affects Fertility

Age can’t be overlooked in your fertility space. It plays a major role in defining your ability to produce quantity and quality of eggs during your ovulation

Since your ovulation revolves around this, it’s best to note the probability of getting pregnant at each stage of a woman’s life. 

This begins from the teenage years, the beginning of your menstrual cycle before or after your first menstruation down to your menopause

On the calculator, it’s shown from age 20 to 39. 

Age is the first stage in getting to know your fertility score through the calculator. 

How Weight & BMI Affects Fertility

Healthiness is key when planning for your child. You might have to consider canceling your slim fit exercises or cutting down your food intake to keep up with the right weight. 

There’s no specific weight before pregnancy however, there’s a healthy range which you must fall under. 

Getting that keeps you away from further problems associated with being underweight or overweight. 

Issues like diabetes, heart disease, hormonal imbalance, menstrual disorder, miscarriages, high blood pressure, gestation, and at times obesity which is attributed to PCOS (polycystic ovary syndrome)  can be done away with if you consistently take good care of your health. 

Embrace eating healthy and getting fit physically through exercise during your period of trying and even after that.  

You must ensure to practice heavy exercises just light ones will do to keep you agile. 

Most women might be shocked about this revelation as well but your height is the other factor in the pre-pregnancy BMI calculation.  

Studies have shown that a mother’s height contributes to the weight of the child

Due to the fact that your height can affect the growth pattern of your growing child, doctors pay close attention to every detail at every level.  

But, how does it affect your chances of getting pregnant?

While this sounds ridiculously impossible, there’s a good height range for taking in as well. 

The ‘right’ height is not predicted alone but it is calculated together with your weight. 

For you to be considered medically for the upcoming stages, the  BMI which is an acronym for Body Mass Index must fall in between a certain range. 

This is your weight divided by your height. It can be in kilograms or pounds for your weight and meters or feet for your height. 

You should fall within the WHO BMI range for the pre-pregnancy stage to be fit.
