About Menopause Age Estimate Calculator

Anchors an estimate on the mother's age at menopause, the strongest single predictor, and applies the reported one to two year advance seen in smokers.

Formula

Heritability-anchored estimate

Estimated age = mother's age at menopause - 1.5 years if a current smoker; the average natural menopause age is about 51

Worked example

With the default values below, Menopause Age Estimate Calculator returns Estimated age at menopause of 51.0. Change any input above and every figure here is recalculated in your browser.

Inputs used

Mother's age at menopauseaccepts 35–60 years: 51 years
Your current ageaccepts 25–60 years: 45 years
Current smokerone of Yes, No: No

Results

Estimated age at menopause: 51.0 years
Years from now: 6.0 years
Smoking adjustment applied: 0.0 years
Uncertainty: Family history explains roughly half of the variation, so individual timing can differ by several years
