You have a probability of concieving each cycle. The expected number of cyclesThe expectated number of cycles is the mathematical average whereby half of all women with your fertility rate will have concieved by. until conception is .

How long will it take you to concieve? Some women go into family planning with an unrealistic expectation of how easy it is to concieve each cycle. Others fret that they'll be one of the unlucky few who is can't conceive without reproductive assistence, even before they start trying. And some of us (myself included) are a simultaneously guilty of both.

The good news is that while the odds of concieving any one cycle may be low, most women will be able to concieve in just a few cycles. The Time To Conception Calculator estimates your fertility rate based on your age, and then extrapulates to find the probability of conception within a year, as well as the average number of cycles to concieve.

Our modal uses the generally accepted probability of conception (25% for those under 25, 20% for 25-30, 15% for 30-35, and 10% for 35-40), although we note that the chances of conception can significantly increase with optimal timing and frequency. [1] found couples who had intercourse ever two or every three days had a 35% chance of conception for those 16-26, and 20% for those 35-39. Even within an age group fertility rates can differ widly^{[2]}. Thus we give you the option to manually estimate your fertility rate.
