This tool is commonly used in insurance and financial planning, where premiums vary based on factors like the number of participants, coverage amounts, or associated risk scores. The calculator ensures a fair and accurate distribution of costs by accounting for the weight of each participant’s contribution.

Formula of Composite Premium Calculator

The Composite Premium is calculated using the following formula:

Composite Premium = (Σ (Individual Premium × Weight)) / Σ Weight

Where:

  • Individual Premium: Premium for each individual or policy in the group.
  • Weight: The factor representing the share or risk contribution of each individual or policy (e.g., number of members, coverage amount, or risk score).
  • Σ: Summation across all individuals or policies.

This formula ensures that each policyholder’s contribution is appropriately weighted, resulting in a composite premium that reflects the group’s overall characteristics.

Example of Composite Premium Calculator

Scenario

An insurance company needs to calculate the composite premium for a group of three individuals. The premiums and weights are as follows:

  • Individual1: Premium = $200, Weight = 2
  • Individual2: Premium = $300, Weight = 3
  • Individual3: Premium = $250, Weight = 4

Step-by-Step Calculation

  1. Calculate the weighted premiums:
    • Individual1: $200 × 2 = $400
    • Individual2: $300 × 3 = $900
    • Individual3: $250 × 4 = $1,000
  2. Add the weighted premiums: $400 + $900 + $1,000 = $2,300
  3. Add the weights: 2 + 3 + 4 = 9
  4. Divide the total weighted premium by the total weight:
    • Composite Premium = $2,300 ÷ 9 = $255.56
