A contractor's annual revenue is $1,850,000. Their workers compensation insurance has a rate of $4.50 per $100 of payroll, and their annual payroll is $425,000. What is their annual workers compensation premium?

Correct Answer

D) $19,125

Annual premium = ($425,000 ÷ $100) × $4.50 = 4,250 × $4.50 = $19,125

Answer Options
A
$20,125
B
$21,125
C
$18,125
D
$19,125

Why This Is the Correct Answer

$19,125 is correct. Workers' comp premium is calculated on payroll, not revenue. Formula: (Payroll ÷ 100) × Rate = ($425,000 ÷ 100) × $4.50 = 4,250 × $4.50 = $19,125. Revenue is irrelevant — it is a deliberate distractor.

Why the Other Options Are Wrong

Option A: $20,125

$20,125 is incorrect. This result would require a payroll of approximately $447,222 at $4.50/$100, or a different rate applied to $425,000. The arithmetic does not align with the given inputs.

Option B: $21,125

$21,125 is incorrect. This is not derivable from the given payroll and rate. It may result from a calculation error such as rounding payroll units incorrectly or applying the rate to a wrong base figure.

Option C: $18,125

$18,125 is incorrect. This would require a payroll of approximately $402,778 — not $425,000. A candidate might arrive here by making an arithmetic error in the division step or misreading the payroll figure.

Memory Technique

Workers' comp formula: (Payroll ÷ 100) × Rate. Think of it as 'cents per dollar of payroll per $100 block.' Revenue is for business planning — insurance is for people (payroll). Always base insurance on payroll.
