Estimate Your IVF Success Probability
Use this IVF success rate calculator to get a rough estimate of live birth probability per cycle and cumulative chance across multiple cycles.
If you are researching fertility treatment, one of the first questions is usually: “What are my IVF chances of success?” This page gives you a practical way to estimate your probability using key factors that strongly influence outcomes, including age, ovarian reserve markers (AMH and AFC), body mass index, smoking, donor eggs, and embryo-related choices.
How this IVF chances of success calculator works
The calculator starts with an age-based baseline estimate of live birth per IVF cycle, then applies adjustments from your other inputs. This creates a realistic directional estimate (not a diagnosis) and also calculates a cumulative chance over multiple cycles.
- Per-cycle chance: Estimated probability of live birth from one cycle.
- Cumulative chance: Probability over 1-4 cycles combined.
- Personalized factors: A breakdown of what increased or decreased your estimate.
Age-based baseline used in this tool
| Age Group | Baseline Live Birth Chance Per Cycle |
|---|---|
| < 30 | 55% |
| 30-34 | 48% |
| 35-37 | 38% |
| 38-40 | 25% |
| 41-42 | 15% |
| > 42 | 7% |
Key factors that influence IVF success rates
1) Maternal age
Age remains the strongest predictor of IVF success with own eggs because egg quality and chromosomal normality decline over time. For many patients, this has a larger impact than any single lifestyle variable.
2) Ovarian reserve (AMH and AFC)
AMH and AFC help estimate how the ovaries may respond to stimulation. They are not perfect predictors of egg quality, but they are useful for expected egg yield and cycle planning.
- Very low AMH/AFC often means fewer eggs retrieved and lower cycle efficiency.
- Moderate-to-good AMH/AFC can support better response and more embryo opportunities.
3) BMI and metabolic health
Both underweight and obesity can affect hormones, endometrial receptivity, and medication response. Modest weight optimization can improve cycle conditions for some patients.
4) Smoking status
Current smoking is linked with reduced ovarian function and lower reproductive outcomes. Quitting smoking is one of the highest-impact pre-cycle changes.
5) Embryo and lab strategy
Blastocyst transfer and PGT-A are commonly discussed options. Depending on age and embryo count, these may improve embryo selection and reduce failed transfers due to aneuploidy.
6) Donor egg IVF
When donor eggs are used, success rates often align more closely with donor age than recipient age, though uterine factors and overall health still matter.
How to interpret your result
Your output includes two practical numbers:
- Estimated live birth chance per cycle (single attempt)
- Estimated cumulative chance (multiple planned cycles)
For example, if per-cycle chance is 30% and you plan 3 cycles, cumulative probability is not 90%. Instead, it is calculated as:
1 - (1 - 0.30)^3 = 65.7%
This better reflects real-world planning and sets more balanced expectations for time, budget, and emotional resilience.
Ways to potentially improve IVF outcomes before treatment
- Complete a full fertility workup early (ovarian reserve, uterine cavity, semen analysis, endocrine labs).
- Stop smoking and limit alcohol.
- Discuss weight, insulin resistance, thyroid function, and vitamin D with your clinician.
- Ask your clinic about blastocyst culture policies and lab-level success rates by age.
- For repeated failures, review embryo genetics, implantation factors, and protocol changes.
- Consider counseling support to reduce treatment stress and improve decision quality.
Frequently asked questions
Is this calculator a medical prediction tool?
No. It is an educational estimator based on common outcome drivers. Your reproductive endocrinologist can provide a more precise prognosis with ultrasound findings, hormone panels, semen parameters, embryo quality, and clinic-specific data.
Can AMH alone predict IVF success?
Not by itself. AMH is useful for ovarian response, but live birth probability also depends on age, embryo genetics, uterine environment, and lab quality.
Why include cumulative chance?
Because many people undergo more than one cycle. Cumulative probability gives a more realistic treatment-planning view than a single-cycle number.
