Premium
A premium is the amount an insurer charges for the coverage described in a policy. It is typically paid in full or in installments, and it is separate from the deductible or retention, which the insured bears when a claim occurs.
Last updated October 13, 2026
How premiums work
The premium is the price of the policy. The insurer sets it through underwriting, which weighs the exposure being insured, the limits and coverage requested, claims history, the size of any deductible or retention, and market conditions. Policies are commonly billed annually, or in installments such as monthly or quarterly, and some are paid through premium finance arrangements.
Premium is only one part of the cost. Depending on the policy and state, a bill may also include taxes, fees, surplus lines taxes, or broker fees, and the policy premium can change at audit or when endorsements are added.
Common premium terms
- Written premium: the total premium on a policy for its term.
- Earned premium: the portion the insurer has earned as coverage time passes.
- Unearned premium: the portion relating to coverage not yet provided, which may be returned on cancellation, depending on the policy and the method used.
- Minimum and deposit premium: a policy that is rated on an exposure base, such as payroll or revenue, may charge an initial deposit and adjust after an audit.
Example
A software company buys a policy with a stated annual premium. It pays a portion up front and the rest in installments. The policy has a $25,000 retention. When a covered claim occurs, the company pays the first $25,000 of loss, while the insurer pays covered amounts above that, up to the limit. The premium is what the company paid for the coverage. The retention is what it bears on a claim.
What to watch for
- Do not compare premiums alone. Compare limits, deductibles, sublimits, exclusions and the financial strength of the insurer.
- Ask whether the premium is fully earned at inception, since some policies have minimum earned premium provisions.
- Understand the payment terms. Missing a payment can lead to a notice of cancellation.
- For rated exposures such as revenue or payroll, keep records, because the final premium may be adjusted.
- Premium is not the same as the limit, which is the most the insurer will pay.
What drives a business insurance premium
Insurers generally look at a combination of the following, though the weight of each varies by line and carrier:
- Exposure base. The measure of how much risk there is to insure, such as revenue, payroll, headcount, number of locations or the value of property. Growth in the exposure base usually raises the premium even if the rate stays the same.
- Class and operations. What the company does, how it does it and how its industry has performed.
- Limits, retention and coverage terms. Higher limits and lower retentions usually cost more. Broader wording and fewer exclusions can also raise the price.
- Claims history. Underwriters study loss runs and the controls put in place afterward.
- Risk controls. Security practices, safety programs, contracts, quality processes and management strength.
- Contracts and customers. Indemnity obligations, liability caps and the kinds of clients served.
- Market conditions. Insurance pricing moves in cycles. See hard market and soft market.
Premium vs. related terms
- Premium vs. limit. The premium is what you pay. The limit of liability is the most the insurer will pay.
- Premium vs. deductible or retention. The deductible or retention is what you bear on a claim. It is not paid in advance like the premium.
- Premium vs. taxes and fees. A bill may add state taxes, surplus lines taxes on non-admitted placements, policy fees or broker fees, which are separate from the policy premium.
- Premium vs. commission. A commission is part of the premium that compensates the broker or agent, which is usually built into the premium rather than added to it. Fee arrangements vary, so ask how your broker is compensated.
Payment, cancellation and audits
Payment plans vary. Some policies are paid in full at inception, while others use installments or premium financing, where a lender pays the insurer and the company repays the lender. If the policy is canceled, the return premium depends on the policy terms, state rules and who initiates the cancellation. A policy may be canceled on a pro rata basis, meaning the refund matches the unused time, or on a short-rate basis, which returns less, and some policies carry a minimum earned premium that is kept regardless. Ask which applies.
Policies rated on an exposure base, such as workers' compensation and some general liability policies, are commonly audited after the policy period, and the final premium can move up or down. Keep clean payroll and revenue records.
A second example: how growth changes premium
A hypothetical company has a general liability policy rated at a purely illustrative $2.00 per $1,000 of revenue. At $10 million of revenue, the premium is $20,000. If revenue grows to $15 million and the rate stays the same, the premium becomes $30,000. The rate did not change, but the premium rose because the exposure grew. If the insurer also raises the rate at renewal, the premium moves by both effects. At audit, if actual revenue differs from the estimate used at inception, the premium may be adjusted.
Questions to ask when comparing quotes
- What are the limits, retention, sublimits and key exclusions on each quote?
- Is the premium fully earned at inception, or is there a minimum earned premium?
- What taxes, fees or surcharges are on top of the premium, and who gets them?
- Is the premium subject to audit, and what exposure base is used?
- What payment options and premium finance terms are available?
- How does the premium compare to last year, and what changed: rate, exposure, limits or terms?
Why it matters for technology, AI, fintech and digital-asset companies
Growth changes exposure quickly. A company that raises funding, adds revenue or launches new products may see premium and terms shift at renewal, so providing accurate, current information during underwriting matters.
A company that doubles revenue or headcount in a year can see a premium increase that has little to do with claims. Underwriters of AI, fintech and digital-asset risks also look at newer variables, such as model governance, data practices, custody controls and regulatory status, and these can affect both price and availability. A premium that looks high for a young company may reflect limited market capacity for the exposure, while a low premium may come with narrow wording. Compare coverage, not just price. See cyber and technology E&O, directors and officers liability and excess and surplus lines for lines where this comes up often.

Frequently asked questions
What is an insurance premium?
A premium is the amount an insurer charges for the coverage described in a policy. It is typically paid in full or in installments, and it is separate from the deductible or retention, which the insured bears when a claim occurs.
What factors affect a business insurance premium?
Insurers typically consider the type of business, its operations, revenue or payroll, claims history, limits and deductibles requested, contract requirements, and market conditions. For specialty lines they also review controls and risk quality. The factors used and their weight vary by insurer and line of coverage.
Is the premium the same as the deductible?
No. The premium is what you pay the insurer for the policy. The deductible or retention is the amount you bear on a loss before the insurer pays. A higher deductible can lower the premium in some cases, though the two are set separately.
Can I get a refund of premium if I cancel?
Sometimes. If you cancel mid-term, the insurer may return the unearned portion, but the amount depends on the policy terms, the cancellation method and any minimum earned premium or fees. Check the cancellation provision and ask your broker before canceling.
What is the difference between written premium and earned premium?
Written premium is the total premium for the policy term. Earned premium is the portion the insurer has earned as time passes under the policy. If a policy is canceled midway, the unearned portion may be returned depending on the policy terms and the method used. Insurers use these terms in accounting and in cancellation calculations.
What is a minimum earned premium?
A minimum earned premium is a portion of the premium the insurer keeps even if the policy is canceled early, regardless of how much time has passed. It is stated in the policy or quote and often applies to specialty policies. Ask whether the premium is fully earned at inception or subject to a minimum.
Can I pay my business insurance premium monthly?
Often, yes, though it depends on the insurer and line. Options can include installments directly with the insurer or premium financing, where a lender pays the insurer and you repay the lender with interest or fees. Check the payment terms, down payment and what happens if a payment is missed.
Why did my premium go up when I had no claims?
Premiums can rise for reasons unrelated to your own claims. Common causes include growth in revenue or headcount, higher limits, market-wide rate changes, loss trends in your industry, changes in the insurer's appetite, and added coverage. Ask your broker to break down what changed between expiring and renewal.
