1. What Is Ultimate Loss Ratio?

The Ultimate Loss Ratio is a key insurance metric that measures the proportion of earned premiums paid out as losses, including incurred but not reported (IBNR) losses. It represents the final loss ratio after all claims are settled.

2. How Does the Calculator Work?

The calculator uses the Ultimate Loss Ratio formula:

Where:

• \( \text{Ultimate Losses} \) — Total losses including paid losses and IBNR reserves (USD)
• \( \text{Earned Premiums} \) — Premiums earned during the period (USD)

Explanation: This ratio indicates the profitability of insurance underwriting. A ratio below 100% indicates underwriting profit, while above 100% indicates underwriting loss.

3. Importance of Ultimate Loss Ratio

Details: The Ultimate Loss Ratio is crucial for insurance companies to assess underwriting performance, set appropriate premium rates, establish adequate reserves, and evaluate long-term profitability.

4. Using the Calculator

Tips: Enter Ultimate Losses and Earned Premiums in USD. Both values must be positive, with Earned Premiums greater than zero for valid calculation.
