Note

This is generic arithmetic using the amounts, rates and factors you entered. It is not an insurance quote, a policy interpretation, or financial advice. No insurer rate, jurisdiction rule, statutory limit or policy wording is built in. Real premiums and payouts depend on underwriting, your policy's exact terms and exclusions, and applicable regulation; confirm with your insurer or a licensed professional.

Frequently asked questions

What is a self-insurance reserve fund meant to cover?+

It's money set aside by an individual or organization to pay for potential losses directly, instead of transferring that risk to an insurance company through premiums — essentially acting as your own insurer for risks you choose to retain.

How does the calculator determine how much I should reserve?+

It typically uses your expected annual loss (frequency times severity) plus a safety margin for adverse years, sometimes informed by historical loss data or industry benchmarks for similar risk exposure.

Why would someone choose self-insurance over buying a policy?+

Self-insurance avoids paying an insurer's loading for profit, administration, and risk margin, which can be cost-effective for large, financially stable entities with predictable, manageable loss patterns and enough capital to absorb bad years.

What's the biggest risk of under-funding a self-insurance reserve?+

A reserve set too low based on average expectations can be wiped out by a single bad year or a cluster of unexpected large losses, leaving no buffer and potentially forcing you to fund losses from unrelated capital or take on debt.

Should the reserve be adjusted over time?+

Yes, reserves should be revisited periodically to reflect actual claims experience, inflation in replacement/repair costs, and changes in the underlying exposure (more assets, more employees, expanded operations), since a static reserve becomes outdated.
