# Underwriting

Updated Oct 1, 2026

Underwriting is how an insurer evaluates risk, decides whether to offer coverage, classifies the applicant, and sets the policy's price or terms. It can affect eligibility, premium, limits, deductibles, exclusions, endorsements, and renewal. Your declarations page, binder, or renewal notice shows the result.

Also called: underwriter

Underwriting is the decision an insurer makes about your [risk](https://riskado.com/insurance-terms/risk/) before it writes a [policy](https://riskado.com/insurance-terms/policy/) and again when it renews one. In the words of the [NAIC (opens in a new tab)](https://content.naic.org/glossary-insurance-terms), it is the process by which an [insurance company](https://riskado.com/insurance-terms/insurer/) examines risk, decides whether to accept it, classifies the risks it accepts, and determines the appropriate rate. You see the result in a [binder](https://riskado.com/insurance-terms/binder/), a [declarations page](https://riskado.com/insurance-terms/declarations-page/), an [endorsement](https://riskado.com/insurance-terms/endorsement/), a renewal notice, or a declination letter.

## How underwriting turns into a price

Underwriting settles eligibility and risk classification, and rating then applies the insurer's filed rating plan to set the premium, according to the [NAIC's consumer auto guide (opens in a new tab)](https://content.naic.org/consumer/auto-insurance.htm). The coverage, limit, and deductible you pick shape the quote and what a claim pays.

Here is an illustrative auto example. The $1,200 premium is an example figure, not an industry average.

Illustrative auto claim with a $500 deductible

Hover or tap a row to highlight it.

| Item | Amount |
| --- | --- |
| Annual premium you pay | $1,200 |
| Covered collision loss | $4,000 |
| Your deductible | $500 |
| Insurer pays ($4,000 minus $500) | $3,500 |
| Your total outlay (premium plus deductible, $1,200 + $500) | $1,700 |

A higher deductible can lower the premium, but you pay that larger amount before the insurer pays a covered loss, according to the [NAIC (opens in a new tab)](https://content.naic.org/sites/default/files/publication-aut-pp-consumer-auto.pdf).

## What changes the outcome

No single percentage or dollar range applies to every underwriting decision. Filed rating plans, policy terms, applicant characteristics, coverage choices, and state law control the result. The common variations, drawn from the [NAIC's auto insurance page (opens in a new tab)](https://content.naic.org/insurance-topics/auto-insurance), are these.

- **Acceptance, declination, or placement.** An insurer can accept you as preferred, standard, or nonstandard, or decline you. The placement decides which rating tier applies.
- **Limits and deductibles.** Higher liability or property limits raise the insurer's potential payment and can raise the premium. A $1,000 deductible generally carries a lower premium than a $500 deductible.
- **Optional coverages.** Dropping collision, comprehensive, or rental reimbursement can lower the premium and removes the matching protection.
- **Medical underwriting.** Where the law permits it, an insurer uses health status to decide whether to offer coverage, at what price, and with what exclusions or limits, according to [Healthcare.gov (opens in a new tab)](https://www.healthcare.gov/glossary/medical-underwriting/). Marketplace insurers cannot refuse treatment or charge more because of a [pre-existing condition (opens in a new tab)](https://www.healthcare.gov/glossary/pre-existing-condition/).
- **Renewal changes.** At renewal an insurer can change the premium, deductible, limits, form, or eligibility, subject to the policy and state law.

An underwriter judges one application. An actuary studies loss data across many policies to develop rates and reserves, according to the [NAIC (opens in a new tab)](https://content.naic.org/glossary-insurance-terms). "Pre-approval" is not a standard insurance term. In health insurance, [prior authorization (opens in a new tab)](https://www.healthcare.gov/glossary/prior-authorization/) is a decision on whether a specific service or drug will be covered. A preliminary indication does not bind coverage; the policy or written approval controls.

## Where you meet underwriting

Underwriting applies to auto, homeowners, condo, renters, life, health, pet, commercial, and workers' compensation insurance, among others, according to the [NAIC (opens in a new tab)](https://content.naic.org/consumer/how-does-insurance-work). You see its effects here:

- A quote or application, where the insurer asks about risk characteristics.
- A binder, which temporarily confirms coverage before the policy is issued.
- The declarations page, which shows the insured, limits, deductibles, premium, and endorsements.
- A renewal notice, especially when the premium, limits, deductibles, or eligibility change.
- A claim letter. A claim decision is usually claims handling and not new underwriting, though a misstatement on the application can lead to rescission or a coverage review.

## What Connecticut and New York require

Both states regulate how an underwriting decision is explained to you.

In Connecticut, [Conn. Gen. Stat. § 38a-976 (opens in a new tab)](https://prdext3.cga.ct.gov/current/pub/chap_705.htm) counts declining or terminating individually underwritten coverage as an adverse underwriting decision, as it does moving a property or casualty risk from preferred to standard or nonstandard status. Under [Conn. Gen. Stat. § 38a-985 (opens in a new tab)](https://prdext3.cga.ct.gov/current/pub/chap_705.htm), the insurer or agent must give the specific reason in writing or tell you it will be provided on written request. A written request made within 90 business days requires the reason and supporting information within 21 business days, subject to statutory exceptions. Under [Chapter 701 (opens in a new tab)](https://www.cga.ct.gov/Current/pub/chap_701.htm), a personal-risk policy generally cannot be declined, cancelled, or nonrenewed solely because of credit history, and the [Connecticut Insurance Department (opens in a new tab)](https://portal.ct.gov/-/media/cid/bulletinpc69theuseofcreditrequiredbypublicact107pdf.pdf) summarizes these protections in Bulletin PC 69.

In New York, [Insurance Law § 3425 (opens in a new tab)](https://www.nysenate.gov/legislation/laws/ISC/3425) requires cancellation notices on many personal policies to specify the grounds and nonrenewal notices to state the reason. [Insurance Law § 3426 (opens in a new tab)](https://www.nysenate.gov/legislation/laws/ISC/3426) applies similar rules to commercial lines. Under [Insurance Law § 2805 (opens in a new tab)](https://www.nysenate.gov/legislation/laws/ISC/2805), adverse action based on credit information must be explained in specific language, including up to four primary influencing factors, and "poor credit history" is not enough. "Underwriting judgment" is not a sufficient reason on its own, according to [DFS OGC Opinion No. 03-07-08 (opens in a new tab)](https://www.dfs.ny.gov/insurance/ogco2003/rg030708.htm).

## Questions to ask your agent or insurer

1.  What underwriting information was used to decide my eligibility and rate? The answer shows whether the decision relied on application answers, claims history, driving record, property details, credit-based information, or medical information.
2.  Is this an underwriting decision, a rating decision, a coverage change, or a claims decision? The category decides which policy terms, notices, and state rules apply.
3.  Which exact policy term changed: the premium, a limit, a deductible, an exclusion, an endorsement, or renewal status? The declarations page or renewal notice should name it.
4.  If my coverage was declined, cancelled, or nonrenewed, what specific reason and notice deadline apply? Connecticut and New York require specific reasons in covered notices.
5.  If a claim is involved, which policy provision controls the payment, and what deductible or limit applies? Claims are generally decided under the issued policy and not the original underwriting.

## Frequently asked questions

### Does underwriting set my premium?

Underwriting decides whether you are eligible and how you are classified, and the filed rating plan then produces the price. The limits, deductible, and optional coverages you choose feed into that price too, so changing them is one way to compare quotes.

### Is an underwriting decision the same as a claim decision?

No. After a loss, the insurer applies the issued policy's coverage, exclusions, conditions, limits, endorsements, and deductible. Application information comes back into play only if the insurer alleges a material misstatement or that you were not eligible, which is a separate dispute.

### Can my credit history affect underwriting?

Insurers can use credit-based information in underwriting, and states set limits. California, Hawaii, Maryland, Massachusetts, Michigan, Nevada, Oregon, and Utah prohibit using credit-based insurance scores to set rates or decide whether to offer or renew coverage, according to the [NAIC (opens in a new tab)](https://content.naic.org/cipr-topics/credit-based-insurance-scores?aff_sub2=freekick).
