In short
Often, yes. An A1C in the prediabetic range, about 5.7 to 6.4, with normal weight and blood pressure commonly still qualifies for preferred or standard plus, an estimated $70 to $85 a month at 45 for $500,000 of Nectar Term over 20 years. With a high BMI or high blood pressure alongside it, the class drifts toward standard, about $100, and a later diagnosis of type 2 diabetes does not change a policy already issued. Your final price is set during underwriting.
Key takeaways
- Prediabetes on its own is usually not a rating. An A1C of 5.7 to 6.4 with normal weight and blood pressure commonly reaches preferred or standard plus, and insurers differ on which.
- What moves the class is the company the A1C keeps: a high BMI, high blood pressure or a family history of diabetes drifts the file toward standard.
- A fasting glucose on the exam that is out of range can cost a class on its own, which is why an A1C in your records matters.
- Underwriters read the trend. Two readings a year apart that both say 5.8 are a different file from one that moved from 5.6 to 6.3.
- A policy already issued is locked in. A type 2 diabetes diagnosis later in the term does not change the price or the coverage.
Prediabetes is a label for a blood sugar reading above normal and below the line for diabetes, and underwriters treat it the same way: as a number read alongside your other numbers, not a diagnosis that sets your class. For most applicants it costs nothing or one class.
This guide shows the A1C and fasting glucose ranges insurers typically use, what each situation costs at 45, what underwriters read around the A1C, what happens if the diagnosis changes after your policy is issued, and what to have ready.
Can you get life insurance with prediabetes?
Yes, and usually at ordinary prices. An A1C in the prediabetic range with normal weight and normal blood pressure commonly qualifies for the preferred class on our pricing by age table, or standard plus at the issuing partners that cap elevated glucose one step below preferred. The applications that drift toward standard are the ones where the A1C arrives with company: a BMI in the 30s, blood pressure above the preferred line, or a parent with diabetes.
Underwriters are pricing the chance the reading becomes type 2 diabetes during a 20-year term, and an A1C of 5.9 in a lean applicant with normal blood pressure carries a different chance than the same reading with a high BMI.
What A1C do life insurance companies accept?
Medical and insurance lines are not the same. The American Diabetes Association defines prediabetes as an A1C of 5.7 to 6.4 percent, or a fasting glucose of 100 to 125 mg/dL, and diabetes at 6.5 or 126 and above. Underwriters use those definitions to decide which guideline applies, then draw their own lines inside the range. A common set:
- A1C under 5.7. Normal. No effect on the class.
- 5.7 to about 6.0. Preferred at many insurers when weight and blood pressure are normal, and preferred plus at a few.
- 6.1 to 6.4. Preferred at some issuing partners, standard plus at others, and standard when there is a high BMI or high blood pressure alongside it. This is where insurers differ most, and where placement with the right partner is worth a class.
- 6.5 or above, on more than one reading. Underwritten as type 2 diabetes, whether or not a doctor has used the word. Our guide to term life insurance with type 2 diabetes covers those guidelines.
These are typical guidelines, not rules. Insurers differ by a few tenths of a point, and most are stricter with younger applicants, because a reading of 6.2 at 30 has more years to become diabetes than the same reading at 55.

How much does life insurance cost with prediabetes?
Start from our rate table. A 45-year-old man in the preferred class pays an estimated $70 a month for $500,000 of Nectar Term over 20 years. Standard runs 40 to 50 percent more, so about $100, and standard plus sits between the two at about $85. Each table step above standard adds roughly 25 percent, a typical industry convention, so Table 2 is about $150.
| What is in your file | Likely rate class | Estimated Nectar Term price, male, 45, $500,000, 20 years |
|---|---|---|
| A1C 5.7 to about 6.0, normal weight and blood pressure | Preferred (preferred plus at a few issuing partners) | $70/mo |
| A1C up to 6.4, normal weight and blood pressure | Preferred or standard plus, depending on the issuing partner | $70 to $85/mo |
| A1C 5.7 to 6.4 with a high BMI or high blood pressure | Standard plus or standard | $85 to $105/mo |
| Exam fasting glucose out of range, or a rising A1C with other markers off | Standard, sometimes Table 1 or Table 2 | $98 to $150/mo |
| A1C 6.5 or above on repeat readings | Underwritten as type 2 diabetes | $85 to $105/mo at best |
Women pay about 18 percent less at every row, and tobacco multiplies any row by roughly 2 to 2.5. Every figure is an estimate, and your class is set during underwriting. Put plainly, prediabetes with a clean file costs nothing to about $15 a month at 45, and prediabetes with a high BMI costs about $15 to $35.
What do underwriters read besides the A1C?
Five things, and together they decide whether the A1C is a footnote or the reason for a class:
- The trend. Two results a year apart that both read 5.8 describe a stable file. A series that moved from 5.6 to 6.3 in 18 months describes one heading somewhere, and underwriters price the direction as well as the level.
- Fasting glucose on the exam. If an exam is ordered, the lab draw includes a fasting glucose, and a reading above about 125 mg/dL can move the class on its own. An A1C, which averages the last two to three months, typically carries more weight than a single fasting value.
- Weight. Build is rated first at every insurer, and a prediabetic A1C with a BMI in the 30s is read as a pair. Our guide to life insurance with a high BMI shows where the build lines fall.
- Blood pressure. Readings above about 135/85 alongside an elevated A1C usually mean standard rather than preferred, even when each would pass alone. Our guide to life insurance with high blood pressure has the ranges.
- Family history. A parent or sibling with type 2 diabetes is noted on most applications. It rarely costs a class by itself, but it tips a file that is borderline on the other four.
Cholesterol is read in the same pass, and a ratio out of range with an elevated A1C often decides between standard plus and standard; our guide to life insurance with high cholesterol covers those numbers. One more item: metformin. Some doctors prescribe it for prediabetes, and in your pharmacy history it looks like a diabetes drug, so a note in your records saying why it was prescribed keeps the underwriter in the prediabetes guidelines.
What if you are diagnosed with type 2 diabetes after the policy is issued?
Nothing changes. A term life policy is underwritten once, at issue, and the class and price are locked for the full term. A diagnosis of type 2 diabetes in year four does not raise the premium or reduce the coverage. The only thing that can reopen an issued policy is a material misstatement on the application, found during the first two years in most states, and an honestly reported A1C is the opposite of that.
The price you are issued at is the price for the whole term. A prediabetic reading that becomes a diabetes diagnosis in year four does not change a policy that already exists, which is why most people apply on the current result rather than waiting for the next one.
It cuts the other way as well: a policy issued at standard because the A1C was 6.3 stays at standard if a later reading comes back at 5.6, unless the issuing partner allows a reconsideration after a year or more of improved results, which is a request rather than a right.
What to have ready, and the no-exam path
Four items cover almost everything an underwriter asks about prediabetes:
- Your most recent A1C, with the date, and any earlier ones so the trend is visible.
- Your doctor's name and practice, so records can be requested without a second round of questions.
- Your current height and weight and your last blood pressure reading, as recorded in your chart.
- A medication list, including metformin if it has been prescribed, and a note of what it was prescribed for.
With an A1C in the records and the rest of the file in range, most prediabetic applications stay 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, and the underwriter confirms your answers against your prescription history and a medical information bureau report. Without a glucose or A1C in your records, an exam is more likely. If we think one is likely, your quote says so. Our guide to the life insurance medical exam explains what the lab draw measures.
The Nectar Term application shows your estimated approval odds and expected decision time before you submit anything, so a reading of 6.2 does not turn into a surprise. We place your application with the issuing partner that rates elevated glucose best, and the issuing company is named on your quote.

Frequently asked questions
Can you get life insurance if you are prediabetic?
Yes, and often at preferred or standard plus rates. An A1C of 5.7 to 6.4 with normal weight and blood pressure is typically not rated on its own. With a high BMI or high blood pressure alongside it, standard is more common, about 40 to 50 percent above preferred.
What A1C is needed for preferred life insurance rates?
There is no single line. Many insurers allow preferred up to an A1C of about 6.0 when the rest of the file is clean, and some allow it up to 6.4. Others cap elevated glucose at standard plus. The issuing partner your application goes to decides where the line sits.
Does prediabetes affect life insurance rates?
Usually by nothing to one class. A prediabetic A1C alone commonly costs nothing or the step from preferred to standard plus, about $15 a month at 45 for $500,000 over 20 years. Paired with a high BMI or high blood pressure, it more often means standard.
Will my life insurance change if I develop type 2 diabetes later?
No. A term policy is underwritten once, at issue, and the class and price are locked for the full term. A later diagnosis does not raise the premium or reduce the coverage, as long as the application was answered honestly.
Do I need a medical exam for life insurance with prediabetes?
Usually not when a recent A1C is in your records. Nectar Term issues up to $2 million without an exam for most applicants under 60. An exam is more likely when there is no glucose or A1C on file, and it includes a fasting glucose that can move the class if it is out of range.
