Frequently asked questions
What is the formula?
For the United States, Canada and Australia this tool divides annual payroll by 100 and multiplies by the rate for the industry you picked. For the United Kingdom and India it multiplies payroll by the percentage rate. Either way the premium is payroll × rate; the two methods only differ in how the rate is written. $500,000 of US office payroll at $0.35 per $100 gives $1,750.
Where do the rates come from?
They are fixed figures coded into the tool for five industry groups in each country, shown in the table of this page. They are estimates for illustration, not published rate filings, class code rates or quotes from any insurer.
Does it use workers’ compensation class codes?
No. You choose one of five broad industries and the whole payroll is priced at that single rate. A business with office and field staff would need separate estimates, since this tool does not split payroll between classes.
What does the per-employee figure mean?
It is the annual premium divided by the number of employees you enter. The employee count does not influence the premium itself, only that line. With $40,000 of construction premium across 10 employees the tool shows $4,000.
What is the India rate?
India is set to 3.25% for every industry, labelled as an ESIC employer contribution in the output. The tool applies it to the entire payroll you enter, with no wage ceiling and no test of which employees qualify, so treat the result as a rough payroll percentage rather than a statement of what an employer owes.
Are experience ratings, discounts or taxes included?
No. There is no experience modification, safety credit, deductible or premium discount, no state or provincial variation, and no surcharges, assessments or taxes. The result is a flat rate times payroll.
Which currencies and units does it show?
Results use the symbol of the selected country ($, £, ₹, CA$ or A$). The effective rate is premium as a percentage of payroll, shown to three decimals, and the monthly cost is the annual premium divided by 12.
What happens with zero or cleared entries?
Clearing the payroll box counts as 0, the same as typing 0, and gives a premium and effective rate of 0. Employee count is held to at least 1, so an employee count of 0, which is also what a cleared box becomes, is treated as 1 and rounded to a whole number.
Is this a quote or a statement of legal obligations?
It is neither. Whether and how coverage is required, and what it costs, depends on the jurisdiction, the scheme and the insurer, and a licensed broker or the insurer governs the actual premium and terms.
Payroll-based workers’ compensation estimate with built-in rates for five countries
A flat rate multiplied by payroll
The estimate works from the payroll figure you enter and a single rate chosen by country and industry. For the United States, Canada and Australia the rate is expressed per 100 units of payroll. For the United Kingdom and India it is a percentage of payroll. The two forms give the same arithmetic, so the effective rate shown at the end always equals the rate in the table converted to a percentage.
The rate table in the code
The table lists every rate the tool can apply, in local currency per 100 of payroll (or percent of payroll for the UK and India). They are estimates built into this tool. The India column is a single figure for all industries, so changing the industry has no effect on it.
| Industry | US | UK | India | Canada | Australia |
|---|---|---|---|---|---|
| Office / clerical | 0.35 | 0.15 | 3.25 | 0.80 | 0.40 |
| Retail | 1.20 | 0.30 | 3.25 | 1.50 | 1.00 |
| Manufacturing | 2.50 | 1.00 | 3.25 | 3.00 | 2.00 |
| Construction | 8.00 | 1.75 | 3.25 | 5.00 | 3.50 |
| Healthcare | 1.80 | 0.50 | 3.25 | 1.20 | 0.90 |
Six runs of the calculator
A US office with $500,000 payroll and 10 employees shows $1,750 a year, $146 a month and $175 per employee. The same payroll in US construction shows $40,000, $3,333 a month and $4,000 per employee. A UK manufacturer with £800,000 payroll and 25 employees shows £8,000 a year, £667 a month and £320 per employee. An Indian retailer with ₹3,000,000 payroll and 12 employees shows ₹97,500, ₹8,125 a month and ₹8,125 per employee. An Australian healthcare employer with A$1,200,000 and 20 staff shows A$10,800 and A$540 per employee. A Canadian office with CA$250,000 and 4 staff shows CA$2,000 and CA$500 per employee.
Reading the per-employee and effective-rate lines
The per-employee number depends on how payroll is spread over headcount, so the same premium looks very different for two firms with the same industry rate but different average wages. The effective rate removes that effect and simply restates the premium as a share of payroll. If the effective rate does not match the rate you expected, check that the country selector is on the intended country.
What the estimate does not include
The calculation has no class-code splits, experience modification, safety discounts, deductibles, taxes or jurisdiction-specific rules, and the rates are not drawn from a filing. Real premiums come from an insurer or a statutory scheme operating under local law, and a licensed broker or the insurer governs the actual terms. Use this as a rough order-of-magnitude figure only.
