Estimate IVF success rate by age, cumulative probability over multiple cycles, live birth teaching rate, and a US cost range from embryo grade, diagnosis, and prior failed cycles. Educational—compare with your clinic's SART or CDC ART report, not this page alone. More tools on our medical calculators hub.

Age is the most significant factor in IVF success rates
Calculate cumulative success rate over multiple cycles
Number of previous unsuccessful IVF cycles
Clinical Pregnancy Rate
36.8%
Per Cycle Success Rate
Cumulative Success
36.8%
1 cycle(s)
Live Birth Rate
32.4%
Per cycle
Probability Analysis:
Favorable per-cycle estimate—still plan for possible multiple cycles.
Cycle-by-Cycle Analysis:
Estimated Cost:
$18,000
Approximate cost for 1 cycle(s) including medications (US average)
Clinical Recommendations:
Important Notes:
Not personalized medical advice. IVF outcomes depend on clinic laboratory quality, transfer policy (fresh vs frozen, single vs double embryo), ovarian reserve labs, and partner factors. Use this calculator for learning and discussion with a board-certified reproductive endocrinologist.
36.8% / cycle
Cumulative 36.8% · Live birth ~32.4%
65.8% cumulative
43.7% per cycle · excellent embryo
70.1% cumulative
Same default profile, three attempts
25.5% cumulative
10.4% per cycle · fair embryo
Age 41, good embryo, 1 cycle: ~11% clinical pregnancy per cycle on this teaching scale.
Starting point before embryo, diagnosis, and prior-failure adjustments. National registry medians differ by year and cycle type—use your clinic's stratified table for decisions.
| Female age | Base clinical pregnancy / cycle | Teaching note |
|---|---|---|
| Under 30 | 45% | Highest own-egg rates in national ART summaries |
| 30–34 | 40% | Still favorable; slight decline vs under 30 |
| 35–37 | 32% | Noticeable drop—AMH/AFC and PGT discussions common |
| 38–39 | 22% | Accelerating age effect on euploidy and yield |
| 40–41 | 12% | Often multi-cycle or donor-oocyte counseling |
| 42–43 | 5% | Low per-cycle with own eggs in population data |
| 44+ | 2% | Donor oocyte or alternative family-building paths |
Under 30 uses 45% in code; 30–34 uses 40%.
| Grade (teaching) | Multiplier | Effect |
|---|---|---|
| Excellent (A/AA) | ×1.15 | Teaching uplift for top morphology / blastocyst grade |
| Good (B/AB) | ×1.00 | Reference tier in this model |
| Fair (C/BC) | ×0.75 | Lower implantation potential on average |
| Poor (D/CC) | ×0.50 | Markedly reduced odds—may reconsider transfer strategy |
| Diagnosis | Model factor | Clinical context |
|---|---|---|
| Ovulatory / tubal factor | 0.95–0.95 | Often similar to population average when other factors favorable |
| Male factor | ×0.90 | ICSI commonly used; severity of sperm parameters matters |
| Unexplained | ×0.92 | Slightly below “best prognosis” cohorts in some registries |
| Endometriosis | ×0.85 | Stage and prior surgery affect outcomes beyond this label |
| Diminished ovarian reserve (DOR) | ×0.70 | Lower oocyte yield and quality—donor paths may be discussed |
| Other | ×0.90 | Catch-all; clinic workup defines real prognosis |
| Cycles planned | Per-cycle (approx.) | Cumulative clinical pregnancy | Profile |
|---|---|---|---|
| 1 | 36.8% | 36.8% | Age 32, good embryo, unexplained (default) |
| 2 | ~35.0% | 57.7% | Same profile, cycle-2 decay teaching |
| 3 | ~33.1% | 70.1% | Same profile, three attempts |
Adjusted rate = Base(age) × Embryo × Diagnosis × max(0.5, 1 − 0.1 × prior failures)
Cumulative after n cycles ≈ 1 − ∏(1 − pcycle) with per-cycle decay in model
Live birth (teaching) ≈ clinical × 0.88
Default form estimate for 1 cycle: $18,000 (procedure + meds only).
The model mirrors how patients search: "IVF success rate at 38," "chances after two failed cycles," or "cumulative IVF odds." We start from age-stratified teaching rates aligned with broad U.S. registry patterns, then apply transparent multipliers you can audit. Your fertility clinic may quote higher or lower numbers based on blastocyst banking, PGT-A, and freeze-all protocols.
After a positive test, pair this planning tool with the IVF due date calculator and beta-hCG weeks tool for early pregnancy timing—not for choosing stimulation doses.
Result: 43.7% per cycle · 65.8% cumulative over 2 cycles
Live birth teaching: ~38.5% per cycle
Result: 25.5% cumulative over 3 cycles (10.4% per cycle)
