🧩 1. Structure of Insurance Premiums: The Principle of Insurance Premiums — Pricing Risk
A friend once asked me,
“Why is my premium higher than yours if we’re the same age?”
It’s not just about age. Insurance companies calculate how risky you are to insure, using complex actuarial science — a field that translates risk into price.
This “price of risk” is known as the Risk Premium.
They analyze data such as mortality rates, accident statistics, or illness probabilities to estimate how likely a claim will occur.
That’s the foundation of actuarial science, which uses life tables, loss ratios, and statistical forecasting to predict the cost of future payouts.
💰 2. The Three Core Components of an Insurance Premium
Your total insurance premium — the amount you actually pay — is made up of three key parts:
- Risk Premium (Pure Premium)
→ The portion used to cover claims like death, illness, or accidents.
→ Calculated directly from probabilities and expected payouts. - Savings Premium
→ A portion set aside and accumulated over time, mainly in endowment or whole-life products.
→ This is what later forms your cash value or maturity benefit. - Expense Loading (Business Expense)
→ Covers administrative costs, agent commissions, system maintenance, and the insurer’s operating margin.
→ Often the least transparent portion to consumers.
When combined, these three elements create your Gross Premium — the actual amount you pay each month.
🧠 3. A Real-World Breakdown Example
Let’s say Mr. A, age 30, buys a whole-life insurance plan for 20 years at $100 per month.
Here’s how that payment might be distributed:
| Component | Amount | Ratio | Purpose |
|---|---|---|---|
| Risk Premium | $30 | 30% | Coverage for death or accidents |
| Savings Premium | $50 | 50% | Accumulated for future return |
| Expense Loading | $20 | 20% | Business operation and commissions |
So, only half of what Mr. A pays is actually “saved.”
The rest goes toward risk coverage and insurer expenses.
🏦 4. Why Expenses Are Often So High
People are often shocked when they discover how much of their early payments go toward business expenses.
This is because, in the first few years, insurers front-load agent commissions, marketing, and administrative setup costs.
It’s part of what’s known as Deferred Acquisition Costs (DAC) — insurers recover these upfront costs over the life of your policy.
📉 5. How the Risk Premium Is Calculated
The math behind a risk premium is surprisingly simple in concept.
If the probability of death for a 30-year-old man in a year is 0.05%, and the coverage amount is $100,000:
$100,000 × 0.0005 = $50
This means, purely from a statistical point of view, $50 would cover the expected loss for one year.
Of course, the real premium is higher because of expenses and profit margins.
💡 6. The Savings Portion — The Power of Time
The Savings Premium isn’t just stored away — it’s invested.
Insurers use long-term investment strategies to generate returns, which later come back to you as maturity or surrender value.
This is why long-term policies usually have a higher savings portion.
In essence, your premium combines protection and investment — a form of financial hybrid.
⚙️ 7. Transparency in the IFRS17 Era
Since the implementation of IFRS17 (International Financial Reporting Standard) in 2023, insurers must clearly separate and disclose their premium components —
Risk Premium, Savings Premium, and Expenses.
This new accounting standard aims to make insurance products more transparent for consumers and investors alike.
⚖️ 8. Net Premium vs. Gross Premium
- Net Premium = pure cost of coverage
- Gross Premium = net premium + expenses + profit margin
When you see how much of your payment goes beyond the pure risk portion, you begin to understand why comparing insurance plans solely by price can be misleading.
🚗 9. Comparing Policy Types — Car Insurance vs. Pension Plans
| Category | Car Insurance | Pension Insurance |
|---|---|---|
| Nature | Pure protection | Protection + savings |
| Composition | 90% risk premium | 50–70% savings premium |
| Term | 1-year renewable | Long-term (10–30 years) |
| Refund | None | Partial or full |
Car insurance focuses almost entirely on risk coverage, while pension and endowment products emphasize long-term savings.
🧮 10. The Science Behind Premium Calculation
Insurance companies use decades of experience data to build models that predict future claims.
They consider variables such as age, gender, occupation, and lifestyle to determine fair pricing.
The final premium combines three critical assumptions:
Mortality/Morbidity Rate + Interest Rate + Expense Ratio.
This is the quiet engine that powers every policy quote you’ve ever received.
Insurance is often seen as just a way to protect against risk.
But in reality, it works on three key pillars: protection, savings, and tax benefits.

🧭 KORI’s Insight
Paying your premium isn’t just a financial transaction — it’s the act of sharing risk with others.
Every contribution you make strengthens the collective safety net.
In that sense, insurance isn’t just about money; it’s about trust quantified.
❓ Frequently Asked Questions (FAQ)
Q1. Do Risk Premiums change every year?
A1. For renewable policies, yes — premiums rise as your age and risk increase.
For non-renewable plans, the risk rate is locked in at the time of contract.
Q2. Are all expenses just agent commissions?
A2. No. Expenses also include administrative fees, IT maintenance, marketing, and risk management costs.
Q3. Does the Savings Premium really belong to me?
A3. Yes, a portion of your payment is accumulated and returned as maturity or surrender value,
after deducting the necessary business expenses.
