The basic formula behind your premium
Employees' Compensation insurance premiums aren't a flat number the insurer pulls from thin air. They're built on a straightforward formula:
Premium = Annual Payroll Total ÷ 100 × Industry Rate
Example: if your company's total annual payroll is HK$1,200,000 and your industry rate is $2.5 (i.e., $2.50 per $100 of payroll), your annual premium is roughly 1,200,000 ÷ 100 × 2.5 = HK$30,000. This is a simplified illustration — actual quotes factor in additional variables, and rates and loadings vary between insurers.
"Annual payroll total" includes every employee's base salary, commission, allowances, double pay, and bonuses — don't leave anything out. Insurers verify payroll figures at renewal or at claim time; if there is a significant gap between what you declared and the actual numbers, it can affect your claim payout.
The 5 factors that drive your premium
Factor 1: Industry risk classification
This is the single biggest driver of your premium. Insurers assign different risk bands to different industries, and rates can differ by a factor of ten or more:
- Low risk (clerical / office-based) — Accounting firms, law firms, IT companies, consultancies. Staff spend most of their time at a desk. These attract the lowest rates in the market.
- Medium risk (retail / F&B) — Restaurants, retail shops, beauty salons. Kitchen work, stock handling, and standing all day push the risk up. When quoting, make sure you separate floor staff from kitchen staff.
- High risk (construction / renovation) — Sites, fitting-out works, working at height. Accident rates are high and claim amounts are large. Rates can be ten times or more above clerical rates, and not every insurer will quote.
"My business has both office and frontline staff — how do I declare them?"
You must split them out. Office staff use the lower clerical rate; frontline staff use the relevant industry rate. If you lump everyone under the frontline rate, you're overpaying — this is the single most common reason owners pay more than they need to.
Factor 2: Annual payroll total
The higher your total payroll, the higher your premium — this is directly proportional. Note that insurers use your projected annual payroll, usually based on the previous year's actual figures. If staff left during the year and weren't replaced, make sure you update the payroll figure at renewal — don't carry forward the old, higher number.
Factor 3: Past claims history
Like car insurance: companies that claim often are viewed as higher risk. Even if your premium doesn't jump immediately after a single claim, multiple claims over a few years can lead to a premium loading at renewal — or the insurer declining to renew altogether. Conversely, a clean multi-year claims record can earn you a No Claim Discount.
Factor 4: Safety measures and OSH performance
Whether you run safety training, whether you keep proper occupational safety records, and whether your workplace has identifiable hazards — insurers look at all of this. This is especially relevant for medium- and high-risk industries: if you can demonstrate a formal safety management system (e.g., regular safety inspections, written safety procedures), some insurers will offer better terms.
Factor 5: Headcount and market competition
A larger workforce generally means a higher total premium — but the per-head premium can actually be lower, because insurers treat it as a larger account with room to negotiate. Market conditions also play a role: if several insurers are competing for business in your industry at the time, quotes will be more aggressive. This is exactly why you want a licensed broker to shop the market for you — you shouldn't have to approach each insurer yourself.
3 legitimate ways to keep your premium down
Method 1: Declare job roles accurately
Office staff (accounting, HR, IT support) and frontline staff belong to completely different risk bands — split them out. For a 10-person company where 6 are office-based and 4 are retail frontline, declaring everyone under the retail rate vs. splitting them properly can make a noticeable difference to your premium. This is entirely above-board and is the most direct way to avoid overpaying.
Method 2: Improve workplace safety — fewer accidents, lower premiums
Investing in safety equipment and training isn't just about protecting your people — it protects your premium costs too. Simple measures like keeping walkways clear, providing proper lifting aids, and regularly inspecting electrical equipment can prevent a lot of common workplace injuries. Companies with a clean multi-year claims record have the strongest negotiating position at renewal.
Method 3: Leverage your size, but don't cut corners
If you have a reasonable headcount, ask your broker to negotiate a group discount with the insurer. Some insurers also offer discounts for multi-year policies paid upfront.
But here is what you must never do:
- ❌ Under-declare headcount or suppress payroll — At claim time, the insurer will verify the numbers. If there is a discrepancy between what you declared and the actual figures, they may reduce or deny the payout. The shortfall comes out of your pocket.
- ❌ Classify high-risk staff as clerical — Declaring a kitchen chef as an "administrative assistant"? If a workplace injury occurs, the insurer will check the actual job duties and can refuse the claim on grounds of misrepresentation. This isn't saving money — it's gambling with your liability.
Premium estimates vs. formal quotes
The formula and factors above are meant to help you understand how your premium is built — an actual quote must be obtained by a licensed insurance intermediary from the insurer, based on your company's specific circumstances. The quick premium estimator on our site uses broad industry ranges for a rough estimate (clearly labelled "not a formal quotation") — it gives you a ballpark figure, not a binding quote.
