Earned Premium
Also known as: EP
Earned Premium (EP) is the accounting recognition of premium revenue over time. When you pay your annual premium up-front, the carrier doesn't "earn" it all at policy inception — it earns proportionally over the 12-month policy term. The unearned portion is a liability on the carrier's balance sheet (and a potential refund on YOUR side if you cancel mid-term).
Two common methods: Pro-rata earned premium (most common; daily basis, simple division) — 6 months elapsed on a $12,000 annual policy = $6,000 earned, $6,000 unearned + refundable. Short-rate cancellation (used by some carriers as a penalty for mid-term cancellation initiated by the insured) — typically 10% surcharge on the elapsed portion, reducing the refund amount. Minimum Earned Premium (typically 25-100% of annual premium) — a floor the carrier keeps regardless of mid-term cancellation, common on policies with high acquisition costs (commercial auto, builder's risk, special-event policies).
Why this matters: when you cancel a policy mid-term (selling the business, switching carriers, going out of business), the refund calculation = Total Premium Paid − Earned Premium − any applicable Minimum Earned Premium − any short-rate penalty. The math affects audit reconciliation, accounts-receivable balances, and the cash flow of switching carriers.
Real-world scenario
Imani is a hypothetical small-business owner; her scenario illustrates how Earned Premium affects a mid-term cancellation refund. It is not based on a specific real customer, claim, or quote from any carrier.
Imani, boutique retail shop owner — Atlanta, GA (hypothetical). 4-person operation, ~$420K annual revenue. Carrying a BOP with $1,800 annual premium + a standalone Cyber Liability policy at $1,560 annual premium. Both policies have a 12-month term from March 15, 2025 through March 14, 2026.
August 30, 2025 (5.5 months / 168 days into the policy year), Imani sells her shop to a buyer who's installing their own coverage. She requests mid-term cancellation effective August 31, 2025. Refund calculation:
BOP policy ($1,800 annual): Pro-rata earned premium = ($1,800 ÷ 365) × 168 days elapsed = $828. Unearned + refundable = $1,800 - $828 = $972 refund. The BOP has NO Minimum Earned Premium clause + no short-rate penalty (standard pro-rata cancellation).
Cyber policy ($1,560 annual): Pro-rata earned premium = ($1,560 ÷ 365) × 168 days = $717. Unearned = $1,560 - $717 = $843. BUT this Cyber policy has a 25% Minimum Earned Premium clause (common on Cyber policies due to high underwriting acquisition cost). Minimum Earned = $1,560 × 25% = $390. Since pro-rata earned ($717) is HIGHER than the minimum earned ($390), the minimum doesn't apply — refund stays at $843. (If Imani had cancelled at month 1, only $128 pro-rata would have been earned, but $390 minimum-earned would apply, reducing her refund.)
Total Imani gets back: $972 + $843 = $1,815. Total she paid for ~5.5 months of coverage: ($1,800 + $1,560) - $1,815 = $1,545 net cost. Annual lesson value: understanding earned-premium math BEFORE cancelling can flag $200-$2,000+ in unexpected minimum-earned charges, especially on cyber, builder's risk, and special-event policies.
How it affects your premium
Earned Premium calculation factors:
- Policy type matters — most BOP, WC, GL, Commercial Property use simple pro-rata earned premium. Cyber, Builder's Risk, special-event, and some Commercial Auto policies use minimum-earned-premium clauses.
- Minimum Earned Premium (MEP) percentage — typically 25-100% of annual premium depending on line of business. 25% is common for Cyber + Pro Liab; 100% is common for special-event + short-term construction Builder's Risk. Read your declarations page.
- Pro-rata vs short-rate cancellation — pro-rata: refund = full unearned portion. Short-rate: 10% penalty on unearned portion (used by some carriers as a small-business retention tool). Whether short-rate applies is on your dec page.
- Cancellation initiated by carrier vs by insured — when carrier cancels mid-term (non-renewal, non-payment, fraud), refund is typically pro-rata with no short-rate penalty. When insured cancels mid-term, short-rate penalties + minimum-earned clauses can apply.
- Underwriting acquisition cost — drives MEP percentage. Policies with high inspection / report-pulling / underwriter-time costs (Cyber, Builder's Risk, hazardous classes) typically carry MEPs to ensure the carrier recovers acquisition cost regardless of policy duration.
- Endorsements + mid-term changes — adding coverage mid-term generates additional premium; the math is the same in reverse (pro-rata earned for the added portion).
- Audit pickup — final earned premium is reconciled at year-end audit using ACTUAL exposure. The pre-audit earned premium is provisional.
For accounting recognition: earned premium = revenue recognized; unearned premium = deferred revenue liability. The audit-adjusted earned premium becomes the final revenue figure for the policy.
Common misconceptions
Myth: If I cancel my policy after 1 month, I get 11 months' worth of refund.
Reality: Not always. Minimum Earned Premium clauses on policies like Cyber, Pro Liab, Builder's Risk, and special-event coverage typically have 25-100% minimums that the carrier keeps regardless of cancellation timing. A $2,000 Cyber policy with 25% MEP keeps $500 minimum on a 1-month cancellation — refund is only $1,500 (not $1,833 pro-rata). Always check the MEP clause on your declarations page BEFORE cancelling.
Myth: Earned Premium is the same as Premium Paid.
Reality: No. Premium Paid is the cash you've handed to the carrier; Earned Premium is the portion of that cash the carrier has RECOGNIZED as revenue for time-of-coverage already provided. Pay $12,000 up-front for an annual policy; 6 months in, carrier has $6,000 earned + $6,000 unearned. The unearned portion sits as a liability on the carrier's balance sheet (and a potential refund obligation to you).
Myth: If I cancel right before audit, I avoid the audit bill.
Reality: No — audit follows the policy regardless of cancellation. The carrier reconciles ACTUAL exposure during the policy period vs estimated exposure. If your audited exposure exceeds the estimate, you owe the difference even if you've cancelled. Some carriers run audits MORE aggressively on cancelled policies because they know they won't have ongoing renewal leverage to offset audit shortfalls. Always plan for audit reconciliation as a non-cancellable obligation.
