Egg Freezing Calculator - Eggs, Cycles, and Cost

The egg freezing calculator is a fertility-planning tool that turns your current age, the live birth chance you want, and the number of children you want from the frozen eggs into three concrete numbers: mature eggs to aim for, stimulation cycles that is likely to take, and the total treatment and storage cost in the United States.

• • Plan elective egg freezing in your 20s or 30s: compare a single cycle at age 30 against two cycles at age 35 and see how the egg target and cost move with age.
• • Estimate cost before a clinic consult: walk into a reproductive endocrinology consult with a cycle count and a dollar range.
• • Decide how many children to plan for: compare the egg target for one child against two or three children at the same age.

Egg freezing (oocyte cryopreservation) is a medical procedure, not a certainty. A fertility specialist should review the inputs against your personal medical history before you commit to a cycle plan.

If you are weighing the egg freezing decision against the population conception chances at your current age, the Fertility By Age Calculator gives a parallel age-based fertility estimate from the same CDC-aligned data.

The egg freezing calculator picks an age band, reads the live birth rate per mature egg and the expected mature eggs per cycle for that band, inverts the cumulative binomial formula to solve for the number of mature eggs needed, then divides by the per-cycle yield and multiplies by the US average cost per cycle plus the storage fee.

• age: Current age in years (20 to 50). Drives the age band, the per-egg success rate, and the expected eggs per cycle.
• targetProbability: Desired probability of at least one live birth, 50% to 95%.
• familySize: 1, 2, or 3 children. Each additional child scales the egg target by a conservative factor.
• storageYears: Years the eggs are expected to remain in storage (1 to 20). Used only for the storage cost line.
• liveBirthPerEgg(age): Age-banded live birth chance per mature oocyte: 6.2% under 35, 5.1% at 35 to 37, 3.4% at 38 to 40, 1.9% at 41 to 42, 1.0% above 42.
• eggsPerCycle(age): Age-banded expected mature eggs per cycle: 10 under 35, 8 at 35 to 37, 6 at 38 to 40, 4 at 41 to 42, 3 above 42.

The binomial inversion assumes each mature egg is an independent trial with the same age-banded success probability, which is the standard simplification used in ASRM-aligned counseling. Real outcomes vary by clinic and individual response, so the result is a planning estimate.

According to ASRM (American Society for Reproductive Medicine), a single frozen mature egg delivers roughly a 6.2% live birth chance for women under 35, and the rate drops to about 1.9% by age 41 to 42, which is the rate schedule this calculator uses.

Because the egg target assumes a normal ovulatory cycle, the Ovulation Calculator is a quick way to confirm that the cycle length and fertile window used by the egg yield numbers match your own cycle.

Four ideas carry the result. Naming them keeps the egg target and cycle count from being read as a clinical prediction.

The 60-egg cap keeps the inversion from generating unrealistic numbers at older age bands, where the per-egg success rate is so low that a 95% target would imply hundreds of eggs. A reproductive endocrinologist uses ovarian reserve testing (AMH, antral follicle count) to set a personal plan.

Stimulation response and anesthesia planning both shift with body mass index, so the BMI Women Calculator is a fast way to confirm the BMI band your clinic will use when it sizes the medication dose.

The form has four short fields: age, target probability, family size, and storage years. The result panel updates as you type.

1. 1 Enter your current age in years: age selects the per-egg success rate and the expected eggs per cycle, so the egg target and the cycle count both move with this single input.
2. 2 Pick a target probability of at least one live birth: 70% is a common planning anchor; 90% is rarely reachable at older ages because the egg target is capped at 60.
3. 3 Choose the number of children planned from the frozen eggs: 1 child uses the entered probability directly. 2 and 3 children raise the family-size target probability and apply a conservative scaling factor.
4. 4 Set the storage window in years: storage is billed annually; the calculator applies a $500 average annual storage fee across the entered window.

A 30-year-old planning two children with a 70% target and 5 years of storage lands in the age 20-34 band (6.2% per egg, 10 eggs per cycle), a family-size target of 85%, and a 1.7x family factor. The result is a 51-egg target, 6 cycles, and a total cost near $98,000.

After you freeze, the egg target lines up with a future conception attempt, and the Conception Calculator is the right tool to estimate the conception date once you decide to thaw.

Using the egg freezing calculator before a clinic consult gives you a defensible cycle plan and a defensible cost range.

• • Age-banded success rate is automatic: the per-egg success rate is selected from the ASRM age bands, so you do not have to remember the 6.2% under 35 versus 3.4% at 38 to 40 numbers in the consult room.
• • Egg target and cycle count are linked: the mature egg target is divided by the age-banded yield per cycle, so the cycle count is the number to discuss with the clinic.
• • Family-size scaling is built in: selecting 2 or 3 children raises the family-size target probability and the egg target, so the same calculator works for one-child and multi-child plans.
• • Cost line items are separated: procedure cost, storage cost, and total cost are separate rows, so you can see how much of the bill is the cycles versus the storage window.
• • Edge cases are clamped and explained: age outside 20 to 50, target probability above 95%, and very large egg targets are clamped, and a limitations note explains the cap.

The same form can be re-used in a year or two to compare a current routine to a planned change, which is the way the ASRM guideline suggests the planning portion of egg freezing should be revisited.

If the egg target is met and a future transfer works, the Pregnancy Calculator turns the resulting last period or conception date into a due date and current week, so the planning chain from freezing to delivery is complete.

The egg target and cycle count depend on age, target probability, family size, and storage window. Three caveats are worth keeping in mind before you commit to a cycle plan.

• • The calculator is a planning tool, not a clinical assessment. Ovarian reserve (AMH), antral follicle count, prior response to stimulation, and medical history determine a real cycle plan.
• • The cost numbers are US averages and do not include anesthesia add-ons, donor sperm if needed, genetic testing, or the future FET cycle. Plan on a wider cost band.
• • Egg freezing is not a certainty of a future live birth. The ASRM guideline frames oocyte cryopreservation as a fertility-preservation option, not an insurance policy.

SART patient resources give a national view of per-cycle yield by age, and they are the source of the 10, 8, 6, 4, and 3 mature-eggs-per-cycle numbers used in the result panel.

According to Mayo Clinic, the average US cost of one egg freezing cycle is about $11,000 in clinic fees plus roughly $4,500 in medications, so a single cycle typically lands near $15,500.

According to RESOLVE: The National Infertility Association, US clinics typically charge $350 to $650 per year for long-term egg storage, which averages to about $500 per year and is what the storage cost output is built from.
