Machine Precision
Governing Mathematical Formula:
Additional Premium Owed = (Audited Exposure - Estimated Exposure) / 100 × Policy Rate per $100

Step-by-Step Mathematical Derivation

1
Original Deposit Premium

Deposit Premium = ($450,000 / 100) × $3.85 = $17,325.00 paid at inception.

2
Audited Final Earned Premium

Earned Premium = ($580,000 / 100) × $3.85 = $22,330.00.

3
Audit True-Up Billing

Adjustment = $22,330.00 - $17,325.00 = $5,005.00 additional premium owed immediately upon audit completion.

Frequently Asked Questions

Why do commercial insurance policies have an annual audit? +
Commercial General Liability and Workers' Comp premiums are adjustable policies based on business size (payroll or gross sales). The insurance carrier audits your books at year-end to true-up premiums based on actual risk exposure.
How do uninsured 1099 subcontractors affect an insurance audit? +
If you cannot provide valid Certificates of Insurance (COI) proving your subcontractors had their own liability coverage, the auditor classifies 100% of their 1099 payments as your own employee payroll, creating huge unexpected audit bills.
