What it means
When an insurance company sells a policy, it collects a payment known as a premium. This total initial amount is called gross premiums written.
However, insurance companies rarely take on 100 percent of the risk themselves. To protect against massive losses, such as a string of major natural disasters, they pass a portion of these policies and their associated payments to other insurers, known as reinsurers.
This practice is called reinsurance. Net premiums written is the crucial figure left over after subtracting these reinsurance costs.
For non-finance managers, understanding this term is vital because it shows the true scale of an insurance business. Gross premiums might look impressive, but they can be misleading if the insurer is simply passing most of that risk and money to other firms.
Net premiums written gives a realistic picture of the business volume the company is actively managing and retaining. This metric serves as the top line for an insurance business, acting much like revenue does for a standard retail or manufacturing company.
It is the starting point for calculating underwriting profitability, tracking market share, and assessing growth over time. Analysts and managers watch this figure closely to see if the company is expanding its active customer base or shrinking its retained risk.
Crucially, net premiums written is not the same as earned income. Insurance companies usually collect payments upfront for a year-long policy.
Under accounting rules, they must earn this money gradually over the life of the policy. Therefore, net premiums written shows what was sold today, while net premiums earned shows what has been recognized as revenue as time passes.
In practice
Real-world examples.
Example
TechShield Insurance sells one million pounds in cyber insurance policies. It pays two hundred thousand pounds to reinsurers to share the risk. Its net premiums written total eight hundred thousand pounds.
Example
BuildSafe, a small business insurer, writes five hundred thousand pounds in contractor policies. It cedes one hundred and fifty thousand pounds to a reinsurer, leaving a net figure of three hundred and fifty thousand pounds.
Example
Metro Fleet, a commercial vehicle insurer, issues ten million pounds in transport policies. Because fleet risk is high, it reinsures half, resulting in five million pounds of net premiums written.
Think of it
“Imagine you run a bakery and take a massive catering order for one thousand pounds. You outsource the pastry making to a local baker for three hundred pounds, keeping seven hundred pounds of the order for yourself. Your net revenue is seven hundred pounds, just like net premiums written.
Formula
Calculation
Net Premiums Written = Gross Premiums Written - Ceded Premiums (Reinsurance)
Example:
- Gross Premiums Written: 1,200,000 pounds
- Ceded Premiums: 300,000 pounds
- Calculation: 1,200,000 - 300,000 = 900,000 pounds
Result: The net premiums written amount is 900,000 pounds.Case study
Seen in the real world.
Oakwood Insurance, a mid-sized provider of property and casualty policies, aimed to expand its market presence. During the financial year, the sales team successfully secured two million pounds in new policy sales, which formed their gross premiums written. However, management recognized that insuring properties in flood-prone regions carried high potential costs. To manage this risk safely, Oakwood partnered with a large reinsurance firm, transferring policies worth six hundred thousand pounds and paying the reinsurer that exact amount. Subtracting the ceded reinsurance from the gross sales left Oakwood with one point four million pounds in net premiums written. For the non-finance managers at Oakwood, this metric was central to their operational planning. It proved that the firm was retaining enough business to cover its overhead and staff costs while safely capping its potential payout exposure. By tracking this figure quarterly, department heads could adjust marketing budgets and ensure they did not take on more risk than their capital reserves could comfortably support.
Watch out
Common mistakes.
- Treating net premiums written as actual cash profit instead of top-line revenue.
- Confusing net premiums written with net premiums earned, ignoring the time element of policies.
- Ignoring the cost of reinsurance when looking at total sales figures.
Questions
People also ask.
Why do insurance companies buy reinsurance?
Insurers buy reinsurance to protect themselves from catastrophic losses, such as a major hurricane or a wave of claims, by sharing the risk and the associated premium with another company.
Is a higher net premiums written figure always better?
Not necessarily. While growth is positive, high net premiums written can be dangerous if the underlying policies are underpriced and lead to heavy claim payouts later.
How does this differ from net income?
Net premiums written is a revenue measure representing sales after reinsurance. Net income is the bottom-line profit after paying all claims, operating expenses, and taxes.
