🛡️ Net written premiums is the premium an insurer writes during a period after deducting what it cedes to reinsurers: the portion of contracted business the company keeps for its own account. Commonly abbreviated NWP and also reported as net premiums written, the measure starts from gross written premiums and subtracts the outward reinsurance premium paid for quota-share, surplus, and excess-of-loss protection.
📐 The ratio of net to gross written premiums is the retention ratio, a standard disclosure that shows in one number how much risk a carrier keeps versus lays off. Retention varies widely by line and strategy: a personal-lines insurer may retain the large majority of its premium, while a catastrophe-exposed specialty writer or a fronting company may cede most of it. The measure is expressed in currency, appears across statutory and management reporting worldwide, and, like its gross counterpart, remains a disclosed KPI for IFRS 17 reporters even though premiums no longer appear on the face of the income statement. Earned over the coverage period, net written premium becomes the net earned base used in loss-ratio calculations under premium-based frameworks.
🎯 Because it reflects risk actually retained, NWP says more about an insurer's own exposure and capital consumption than the gross figure does: solvency requirements and net loss experience follow retained business, not written volume. Movements in the gap between gross and net premiums also tell a strategic story: widening cessions can signal capital relief, catastrophe de-risking, or hardening reinsurance appetite, while rising retention often accompanies confidence in pricing or costly reinsurance markets. Analysts therefore read gross growth, net growth, and retention together to understand both commercial momentum and risk appetite.
