Home / Calculators / IVF success and prediction / IVF success rate
Every calculator in one place, free and with no sign-up. Results show instantly — we don't hide them behind a form. Each one explains what the number means, where the reference ranges come from, and what it cannot tell you.
A calculator sees three or four figures. A specialist sees your history, your scans, your partner's results, and how you actually responded to treatment. If you're between cycles, changing clinics, or something in your results doesn't add up, a second opinion is the fastest way to find out whether anything would be done differently.
Free first consultation. No obligation to start treatment, and it doesn't affect your care at your current clinic.
These tools provide general information and are not a diagnosis or a substitute for assessment by a qualified clinician. Reference ranges and sources are stated on each calculator. Predictive estimates describe groups of people and cannot predict an individual outcome.

A range across successive cycles, from age, egg source and previous attempts.
Population estimateAn average for people with your inputs, not a prediction for you. Individual outcomes vary widely around it.
Live birth per embryo transferred, by age, using your own eggs. Age is the single strongest predictor, but clinic, embryo quality and the reason for treatment all move the number.
Source — HFEA published age bands for live birth per embryo transferred, 2023 data (preliminary, not yet validated by HFEA): 35% under 35, 27% at 35 to 37, 16% at 38 to 39, 11% at 40 to 42, 5% at 43 to 44. UK national figures; Indian clinic outcomes vary and are not centrally published in a comparable form. Ask your clinic for its own rate in your age band.
The bands on this page are drawn from published sources but have not yet been reviewed by our medical team, and some vary by laboratory or assay. Check against the reference range printed on your own report.
At the time of egg collection
That falls in the 28% or above band.
Your result of 35 % per transfer sits in the highlighted band. Bands are reference points used alongside clinical findings — not a diagnosis.
At the higher end of national figures. Still per transfer, not per cycle started — some cycles do not reach transfer.

These tools apply across the process rather than at one point in it.
Per embryo transferred. Some cycles do not reach transfer at all, so the chance per cycle started is lower than the figure shown.
Clinics differ in who they treat and how they count. A rate per transfer, in your age band, using your own eggs, is the comparable number to ask for.
No. With donor eggs the donor age drives the outcome and recipient age matters far less. Use the donor egg calculator instead.

A national average for your age band, not a prediction for you. Clinic, embryo quality and cause of infertility all move it. Nothing here is a diagnosis or a substitute for assessment by a clinician.
A calculator gives you a number. These explain what it means, and what it does not.
