The calculator uses the Endorsement Pro Rata formula:
Where:
Explanation: The formula calculates the portion of the premium that corresponds to the remaining time in the policy period.
Details: Accurate pro rata calculations are essential for fair premium adjustments when modifying insurance policies, ensuring both insurers and policyholders are treated equitably.

Q1: When is Endorsement Pro Rata used?
A: It's used when making mid-term changes to insurance policies, such as adding or removing coverage, changing insured items, or adjusting policy limits.
Q2: How does pro rata differ from short rate?
A: Pro rata provides a proportional refund based on time, while short rate typically retains a penalty for early cancellation, resulting in a smaller refund.
Q3: Can this calculation be used for policy cancellations?
A: Yes, pro rata calculations are commonly used to determine refund amounts when policies are cancelled mid-term.
Q4: What if the policy period isn't exactly one year?
A: The formula works for any policy period length as long as you use consistent time units (days are recommended for precision).
Q5: Are there situations where pro rata doesn't apply?
A: Some policies may have minimum earned premium clauses or other special provisions that override standard pro rata calculations.
