A woman must give birth almost every year to qualify for a high maternity pension.

Economist Svetlana Sazanova tried to figure it out in the new rules for calculating the so-called "maternity pension," which are currently being discussed in the State Duma.

Deputies want to end the practice of allowing mothers to count only six years of maternity leave toward their pensionable service. They also want to limit the number of children whose care can be paid for with pension points to a maximum of four.

Instead, it is proposed to introduce a progressive scale for calculating the "maternity pension," which would allow for an unlimited number of years of childcare, and for each new child, more points would be awarded.

There is a nuance here.

To qualify for a maternity pension of 38 rubles, a woman must have 18 to 20 children, which will earn her 200 points. By comparison, having seven children will only earn her 32 points. 

Furthermore, the child must be born between the ages of 18 and 43. This means that to qualify for a high pension, children must be born every 15-16 months.
