Menopause Age Calculator
Use this free calculator to estimate where you are in the menopause transition and the age range when you're most likely to reach menopause. It combines your age, cycle pattern, family history, smoking status, surgical history, and a symptom check inspired by the Greene Climacteric Scale — a validated 21-item questionnaire used in menopause research and clinical practice.
This is an estimate, not a diagnosis. For a fuller picture, see our 4 stages of menopause guide and bring your results to a clinician.

How this calculator works
The calculator combines four well-established signals used by menopause specialists:
- Your age — the strongest contextual factor. Average natural menopause sits around 51–52, with most women reaching it between 45 and 55.
- Cycle pattern — the Stages of Reproductive Aging Workshop (STRAW+10) framework uses cycle changes as a primary marker of where you are in the transition.
- Family history & lifestyle — mother's age at menopause is the single strongest individual predictor; current smoking shifts menopause ~1–2 years earlier on average.
- Greene Climacteric Scale–inspired symptoms — 15 items across vasomotor, psychological, somatic, and sexual domains, scored 0–3, summed to give a symptom-burden band that helps locate you in the transition.
The output is a stage estimate, a symptom-burden band, and a likely menopause age range. Surgical menopause (both ovaries removed) is treated as an immediate menopause regardless of age, and significant symptoms before 40 are flagged for clinician follow-up to rule out primary ovarian insufficiency.
Frequently asked questions
How accurate is a menopause age calculator?
A calculator like this gives an educated estimate, not a diagnosis. It combines well-established clinical signals — your age, cycle pattern, family history, and symptoms scored on a Greene-Climacteric-style framework — to suggest where you likely sit in the menopause transition. Hormones fluctuate and life circumstances vary, so use the result as a starting point for a conversation with your clinician.
What is the Greene Climacteric Scale?
The Greene Climacteric Scale is a validated 21-item questionnaire developed by Dr. John Greene that measures menopause symptom severity across psychological, somatic, vasomotor, and sexual domains. It's widely used in research and clinical practice to track symptom burden over time.
At what age does menopause usually start?
The average age of natural menopause is around 51 to 52, with most women reaching it between 45 and 55. Perimenopause — the transition phase with symptoms — typically begins 4 to 8 years earlier. Menopause before age 40 is considered premature and deserves specialized care.
Can I predict my exact menopause age?
No tool can predict an exact date. The strongest single predictor is your mother's age at menopause, followed by smoking status (smokers reach menopause ~1–2 years earlier on average) and certain medical history. This calculator weighs those factors to produce a likely range, not a fixed date.
What does my symptom score mean?
Higher scores indicate a heavier symptom burden across the Greene domains (vasomotor, psychological, somatic, and sexual). A higher score combined with cycle changes makes perimenopause more likely. A low score in your 40s doesn't rule out the transition — many women have minimal symptoms early on.
