Allocate a total premium across locations, entities or lines in proportion to TIV, payroll, sales or any other basis.
How the premium allocation calculator works
Package and multi-location programs are often billed as one premium but need to be split for internal cost allocation, invoicing subsidiaries or state filings. Allocation by exposure is the fairest standard method.
Formula
Allocated premium = Total premium × Item basis ÷ Total basis.
How to use it
Enter the total premium.
List each location or entity with its allocation basis.
Choose whether to round to whole dollars.
Worked example
$85,000 across $12.5M, $6.8M and $2.2M of TIV allocates $49,418, $26,884 and $8,698.
Frequently asked questions
What basis should I use?
Use the exposure that drives the premium: TIV for property, payroll for workers comp, sales for GL, vehicles for auto.
How are rounding differences handled?
Amounts are rounded with the largest-remainder method, so whole-dollar allocations add exactly to the total and each item is off by less than a dollar.
