Egg Freezing Calculator
What Are My Chances?
Estimate your likelihood of having a baby from frozen eggs based on your age and number of eggs stored
Based on real outcomes: This calculator uses data from nearly 3,000 patients at world-leading fertility centers, published in RBMO 2025 (Cobo et al.) and JAMA Network Open 2023 (Fouks et al.).

Estimated chance of at least one live birth
Key things to know
- These are real outcomes from patients who returned to use their eggs
- More eggs = higher chances, but no number guarantees success
- Freezing eggs younger gives better results even with fewer eggs
- Your individual results may vary based on egg quality and other factors
How age and egg numbers affect success
| Age at Freeze | 1–9 eggs | 10–14 eggs | 15–19 eggs | 20+ eggs |
|---|---|---|---|---|
| <35 years | 48% | 44% | 77% | 84% |
| 35–37 years | 37% | 47% | 53% | 73% |
| 38–40 years | 19% | 41% | 41% | 57% |
