In short
Yes. Hypothyroidism treated with levothyroxine, with stable lab results on a steady dose, is typically rated as if it were not there, and preferred is common. At 40, that is an estimated $47 a month for $500,000 of Nectar Term over 20 years. Treated hyperthyroidism or Graves' disease with stable results commonly earns standard or better, a recent diagnosis or unstable levels is usually postponed until they settle, and a thyroid cancer history is a separate question with its own waiting period. Your final price is set during underwriting.
Key takeaways
- Treated hypothyroidism is one of the few diagnoses underwriters routinely price as if it were not there. A steady levothyroxine dose and a TSH in range typically keep preferred open.
- Hyperthyroidism and Graves' disease are rated on the result of treatment. Stable lab results after medication, radioactive iodine or surgery commonly earn standard or better.
- Instability costs time, not money. A recent diagnosis or a dose still being adjusted is usually postponed for a few months rather than rated.
- Thyroid cancer is a separate question. Treated papillary cancer, the most common type, is often insurable at standard or a table rating after a waiting period that depends on the stage.
- Underwriters read three things: your TSH results over time, your medication and dose, and the dates of any treatment.
Most thyroid conditions cost nothing at underwriting. Hypothyroidism on a steady dose of levothyroxine is about as routine as a condition gets for an underwriter: a lab value, a pill, and a result that stays in range year after year. The rating follows the lab results, not the diagnosis.
This guide covers how underwriters read hypothyroidism, hyperthyroidism and Graves' disease, what each typically costs at 40, where thyroid cancer fits, why an unstable level means a wait rather than a rating, and what to have ready.
Can you get life insurance with hypothyroidism?
Yes, and in most cases at the same price as someone without it. Hypothyroidism treated with levothyroxine, with a TSH in the normal range on a dose that has not changed recently, typically qualifies for preferred on our pricing by age table, and preferred plus at many insurers when the rest of the file is clean. Hashimoto's thyroiditis, the autoimmune cause behind most adult hypothyroidism, is read the same way once it is treated.
Underwriters are asking one question: is the level stable? They answer it from your lab results, usually TSH and sometimes free T4, and from your prescription history. A diagnosis by itself does not set your class. A stable number does. The American Thyroid Association explains what TSH measures and why it moves.
Does taking levothyroxine affect life insurance?
No, not when the results are stable. Levothyroxine is the reason the level is in range, and underwriters know it. What they read from the prescription history is the trajectory: one dose filled on schedule for two years reads as controlled, and a dose changed twice in six months reads as a condition still being adjusted. A common set of guidelines:
- Treated, TSH in range, dose steady for six months or more. Preferred or preferred plus. The condition does not cost a class.
- Treated, TSH a little out of range, or dose changed in the last few months. Postponed until a follow-up test shows the new dose has settled, typically a few months.
- Untreated, or a diagnosis with no follow-up on file. Usually postponed until there is a treated result to look at. Mild untreated hypothyroidism, with a TSH only slightly above range, is priced at standard by some insurers.
These are typical guidelines, and insurers differ. Complications are uncommon, come from hypothyroidism left untreated for years, and are rated as their own conditions.

Can you get life insurance with hyperthyroidism or Graves' disease?
Yes, once it is treated. An overactive thyroid is rated on what treatment has done to it. Graves' disease is the most common cause, and the three treatments underwriters see are antithyroid medication, radioactive iodine and surgery. A common set of guidelines:
- Treated, levels stable for six to twelve months. Commonly standard or better, and preferred at some insurers once the results have held for a year or more. Many people treated with radioactive iodine or surgery end up on levothyroxine, and from then on the file is read as treated hypothyroidism.
- Recently diagnosed, or on antithyroid medication with levels still moving. Usually postponed until the results settle, often three to six months after the dose stops changing.
- Untreated, or with complications. Postponed. Graves' eye disease and a heart rhythm problem such as atrial fibrillation are the two complications underwriters look for, each rated separately.
Instability costs time, not money. A dose changed in the last few months or a TSH outside the range typically means a postponement of a few months, after which the file is priced on the new result. Underwriters price the follow-up test, so a file that arrives with it is priced once instead of postponed and priced later.
How much does life insurance cost with a thyroid condition?
Start from our rate table. A 40-year-old man in the preferred class pays an estimated $47 a month for $500,000 of Nectar Term over 20 years. Standard runs 40 to 50 percent more, so $66 to $70. Each table step above standard adds roughly 25 percent to the standard price, a typical industry convention, so Table 2 is about $102 and Table 4 about $135.
| Your thyroid condition, as the records show it | Likely rate class | Estimated Nectar Term price, male, 40, $500,000, 20 years |
|---|---|---|
| Hypothyroidism on levothyroxine, TSH in range, dose steady | Preferred, and preferred plus at many insurers | $47/mo |
| Hyperthyroidism or Graves' disease, treated, results stable for six to twelve months | Standard or better | $47 to $70/mo |
| Recent diagnosis, dose changed in the last few months, or TSH out of range | Postponed until a follow-up result shows it has settled | No price until the level is stable |
| Papillary thyroid cancer, treated, past the insurer's waiting period | Standard to Table 2, depending on stage | $66 to $102/mo |
Women pay about 18 percent less at every row, and tobacco multiplies any row by roughly 2 to 2.5. These are estimates, set during underwriting, and the issuing partner's own guidelines may land a step above or below them. For how age and term length move the rest of the price, see our guide to how much term life insurance costs.
Can you get life insurance after thyroid cancer?
Often, yes, but this is a separate question, and the answer depends on the type, the stage and the time since treatment. Papillary thyroid cancer, the most common type, also has the best outlook, and underwriters treat it differently from most cancers. A common set of guidelines:
- Papillary or follicular cancer, small, removed completely, no spread. Often insurable at standard or a low table rating after a waiting period from the end of treatment. The wait is commonly months rather than years for the smallest tumors, and longer when lymph nodes were involved.
- Larger tumors, or spread to lymph nodes. A longer waiting period, then a table rating that typically eases as the years pass. Some insurers use a temporary flat extra instead, a fixed charge for a set number of years.
- Medullary or anaplastic thyroid cancer. Rated far more cautiously, with long waits and declines at many insurers.
The waiting period is not a judgment. Underwriters are waiting for the follow-up results, usually a thyroglobulin blood test and a neck ultrasound, to show that nothing has come back. After a thyroidectomy the TSH is sometimes held deliberately low; underwriters read that as part of the treatment plan, not as instability. Insurers differ more on cancer histories than on almost anything else.
Thyroid nodules are a smaller question: a nodule shown to be benign typically costs nothing, and one never followed up is usually postponed until it has been.
What do underwriters read in a thyroid file, and do you need an exam?
Three items cover nearly everything an underwriter asks:
- Your TSH results, with dates, for the last year or two, and free T4 if your doctor tracks it.
- Your medication and dose, how long you have been on the current dose, and the date of the last change.
- Treatment dates, if there was more than medication, and for a cancer history the pathology report and the latest follow-up results.
With stable results and records that match your answers, a thyroid file nearly always stays on the no-exam path: Nectar Term issues up to $2,000,000 without an exam to most healthy applicants under 60, depending on the issuing partner, with your answers confirmed against your prescription history and a medical information bureau report. Records get requested when the last result on file is old or the dose changed recently; an exam is more likely for a cancer history or a condition with no result on file at all. If we think either is likely, your quote says so, and our guide to the life insurance medical exam explains what the exam checks.
The Nectar Term application shows your estimated approval odds and expected decision time before you submit anything, so a dose that changed last month shows up as a likely postponement on screen rather than two weeks later. A thyroid condition is often read alongside weight and blood pressure; our guides to life insurance with high blood pressure and life insurance with a high BMI cover how each is rated, and the same records-over-labels logic runs through life insurance with asthma and even life insurance with a DUI, where the record is a driving record.

Frequently asked questions
Can you get life insurance if you have hypothyroidism?
Yes. Hypothyroidism treated with levothyroxine, with a TSH in range on a steady dose, is typically rated as if it were not there, and preferred is common. A recent diagnosis or a dose still being adjusted is usually postponed for a few months rather than rated.
Does hypothyroidism affect life insurance rates?
Rarely, once it is treated and stable. Most insurers allow preferred, and often preferred plus, on levothyroxine when the lab results are in range. Untreated hypothyroidism, or a level that is out of range, usually means a postponement until a follow-up test shows it has settled.
Does taking levothyroxine affect life insurance?
Not on its own. Underwriters price the lab results, not the prescription, and a steady dose filled on schedule is the evidence they want that the condition is controlled. A dose changed in the last few months is what draws a postponement.
Can you get life insurance with Graves' disease?
Yes, once it is treated and the results are stable. Treated hyperthyroidism with levels that have held for six to twelve months commonly earns standard or better, and preferred at some insurers after a year. Active disease, or levels still moving, is usually postponed until they settle.
Can you get life insurance after thyroid cancer?
Often, after a waiting period. Treated papillary thyroid cancer that was small and removed completely is commonly insurable at standard or a low table rating once the insurer's waiting period has passed and the follow-up results are clean. Larger or more aggressive cancers wait longer and are rated more heavily. Insurers differ widely here.
