Definition
1. Insurance. The sum paid or agreed to be paid by the insured to the insurer as the consideration for a contract of insurance. The premium is typically expressed as a rate applied to the value or amount at risk and may be paid in full at inception or in installments. It is the price the insured pays in exchange for the insurer's promise to indemnify against specified losses.
2. Finance and lending. A bonus, bounty, or additional sum paid above a base price or par value. In bond markets, a security trades at a premium when its market price exceeds its face value. In lending and contract contexts, a premium may describe any extra consideration offered to induce a party to enter a transaction — for example, a call premium paid to retire a bond early, or a control premium paid in an acquisition above prevailing market price.
3. General commercial law. Any reward, incentive, or additional consideration offered to encourage a specific act, transaction, or behavior. Historically applied to bounties offered by governments or private parties to stimulate commerce, discovery, or desired conduct.
Common Language
Modern common usage (Wiktionary): "Superior in quality; higher in price or value. High-end; belonging to the market segment between mid-market and luxury."
Historical common usage (Webster's 1913): "A reward or recompense; a prize to be won by being before another, or others, in a competition; a bounty."
The everyday adjective sense — denoting superior quality or prestige — carries no legal weight and should not color legal interpretation of the term. In legal instruments, "premium" is almost always a noun with a precise transactional meaning: it identifies a specific payment obligation, not a quality tier. Researchers reading historical commercial documents should note that Webster's 1913 sense (bounty, reward) tracks the older legal usage in senses 2 and 3 above, and does appear in historical statutes and contracts, but the insurance sense has been dominant in legal usage since the eighteenth century.
Common Confusion
Premium vs. consideration: In insurance law, the premium is the consideration furnished by the insured, but the two terms are not interchangeable in all contexts. A court analyzing whether a contract is supported by consideration will apply a broader inquiry; noting that a premium was paid establishes the insured's side of the bargain but does not resolve every consideration question (e.g., whether the premium was actually received, or whether a binder provided coverage before payment). Historical sources sometimes use "consideration" and "premium" synonymously in insurance definitions, which can mislead researchers into assuming the terms are always co-extensive.
Premium vs. premium tax: The premium as a contractual payment is distinct from the premium tax, a state-level excise tax imposed on insurers based on gross premiums written. Statutes and regulatory filings may refer to both concepts in proximity; researchers should distinguish between the payment obligation running between insured and insurer and the fiscal obligation running from the insurer to the state.
Recognized Forms
/SUBTYPES
Net premium: The pure risk component of the premium, calculated from expected losses without loading for expenses or profit.
Gross premium: The net premium plus expense loading, profit margin, and other additions; the amount actually charged to the insured.
Earned premium: The portion of the premium that corresponds to the period of coverage already elapsed. Relevant in mid-term cancellations and regulatory reporting.
Unearned premium: The portion of the premium allocable to the unexpired coverage period. Insurers are obligated to return unearned premiums upon cancellation; this concept appears frequently in insolvency and regulatory contexts.
Single premium: A premium paid in one lump sum at policy inception rather than in periodic installments.
Control premium: In mergers and acquisitions, the excess consideration paid above market price to acquire a controlling interest in an entity.
Call premium: In bond and debt instruments, the additional amount above par value paid to retire a security before maturity.
Why It Matters in Research
The insurance sense of premium is so dominant in modern legal literature that researchers can mistake it for the term's only legal meaning. Historical documents — particularly colonial-era statutes, early commercial agreements, and prize or bounty legislation — use "premium" in the sense of a reward or inducement, closer to Webster's 1913. Reading such documents through a modern insurance-law lens will distort their meaning.
In insurance regulatory materials, the distinction between earned and unearned premium is operationally critical. Solvency regulations, reserve requirements, and consumer protection statutes governing cancellation rights all turn on this distinction. Law Mind corpus materials from the late nineteenth and early twentieth centuries may not use this earned/unearned vocabulary consistently, because the actuarial and regulatory frameworks that formalized it developed over time.
The premium tax context introduces a separate layer of complexity. State premium tax statutes use "premium" as a defined term, and that statutory definition may differ from the common law insurance meaning — particularly in how it treats reinsurance premiums, annuity considerations, and assessments paid to mutual companies. Researchers should not assume that a judicial definition of "premium" in a coverage dispute controls interpretation of the same word in a tax statute.
In securities and M&A research, the premium concept appears in appraisal litigation (fair value determinations), going-private transactions, and analyst commentary. The question of whether a control premium should be included or excluded in statutory appraisal is a live area of corporate law with significant jurisdictional variation; Law Mind materials on this topic will need to be read with attention to the governing state's appraisal statute and case law.
Finally, researchers encountering "premium" in older mortgage and usury materials should be alert: courts and statutes sometimes treated loan origination fees or bonus payments above stated interest as "premiums," with implications for usury analysis. This usage is rare in modern law but appears in nineteenth-century cases and treatises.
Historical Dictionary Support
The historical dictionaries converge on a single core definition for the insurance sense: the premium is the consideration paid by the insured to the underwriter, computed as a rate on the amount at risk. Burrill, Black's (both editions), and Bouvier all cite Phillips on Insurance for this proposition, making Phillips the authoritative period source. Burrill helpfully notes the Latin root (præmium, reward) and cross-references Kent's Commentaries, situating the concept in the broader commercial law of marine underwriting.
Bouvier extends the definition usefully by noting that premiums could be paid partly in cash and partly by promissory note, and that mutual insurance companies operated under a different structure in which the insured building itself might be subjected to assessment — an early form of the assessment mutual model that complicates the clean premium-for-coverage bilateral picture assumed by the other sources.
Anderson's entry is the weakest of the group; its definition of "premium" is fragmentary and appears to be incompletely transcribed in the source material, though it does capture the reward and price senses. The Rapalje & Lawrence entry appears to be misassigned in the source corpus — the text provided describes a procedural rule regarding solicitors and pleading, which bears no relationship to premium; researchers relying on that source for this term should verify the underlying volume.
What the historical dictionaries collectively miss is any treatment of the earned/unearned distinction, the regulatory significance of premiums in solvency frameworks, or the securities-law premium concept. These are twentieth-century developments absent from the shelf sources entirely.
Jurisdictional Note
Insurance premium law is substantially state-regulated in the United States. Rate regulation, form approval, and the rules governing return of unearned premiums on cancellation vary by state. In some states, prompt return of unearned premium upon cancellation is a statutory requirement enforceable against the insurer; in others, it is governed by policy terms. Premium tax rates and the definition of taxable premiums differ materially across jurisdictions.

The premium tax credit reduces the effective cost of premiums for qualifying individuals purchasing coverage through exchanges; the legal definition of "premium" in this context is governed by federal statute and IRS regulation, which may differ from state insurance law definitions.
