Comprehensive Guide to Term Insurance Premium Calculation: Formula & Examples
Term insurance is one of the most straightforward forms of life insurance. Its simplicity and affordability make it a popular choice among individuals seeking financial security for their families. However, understanding how the premiums are calculated can be a bit daunting. In this guide, we break down the process into an easy-to-understand formula with real-life examples, ensuring you grasp the concept thoroughly.
Understanding Term Insurance
Before delving into the premium calculation, let's briefly understand what term insurance entails. Term insurance provides coverage for a specified term, typically ranging from 10 to 30 years. If the policyholder passes away during the term, the beneficiary receives the sum insured. If the policyholder survives the term, no payout is made, and the policy simply expires.
Factors Affecting Term Insurance Premiums
Several factors influence the cost of term insurance premiums, including:
- Sum Insured: The coverage amount that the policy provides.
- Age: The age of the policyholder at the time of purchase.
- Term: The duration of the policy.
- Rate: The premium rate per unit of sum insured, which varies by insurer and policyholder risk profile.
Term Insurance Premium Calculation Formula
The formula to calculate the term insurance premium is as follows:
Premium = (Sum Insured * Age * Term * Rate) / 1000
Here, the input parameters are:
Sum Insured(USD): The coverage amount you want the policy to provide.Age(years): The age of the policyholder at the policy start.Term(years): The length of the policy.Rate(%): The premium rate per unit sum insured.
The output:
Premium(USD): The amount you need to pay for the term policy.
Real-Life Example
Let's take an example to illustrate the calculation:
Imagine John, a 35-year-old man, wants to purchase a 15-year term insurance policy with a sum insured of USD 300,000. The insurer offers a premium rate of 0.6%. The premium calculation will be as follows:
Premium = (300000 * 35 * 15 * 0.6) / 1000 = 94500 USD
So, John will need to pay USD 94,500 for his term insurance policy over the 15-year period.
Validating the Inputs
All inputs must be valid positive integers to obtain a meaningful premium amount. Here are some conditions to validate the inputs:
- The
Sum Insured,Age,Term, andRatemust all be greater than zero.
If any of these conditions are not met, the formula should return an 'Invalid input' message.
