Tools / Protect / Chapter 17 · Insurance: What to Protect, What to Absorb
Insure or absorb?
Insurance is best at transferring losses that would ruin you. For small, affordable losses, paying the premium usually costs more than it pays back on average. Test a policy on both measures.
1 · The idea
Expected loss and loading
Multiply the chance of a claim by what the policy would actually pay: that is its average value to you. Loading shows how much more you pay in premium than the policy returns on average, which is how insurers cover costs and profit. The ruin test asks: if this happened, could my savings absorb it?
The formula
Expected payout = probability × (loss − excess) Loading = premium ÷ expected payout − 1
- probability
- chance of the loss in a year
- loss
- size of the loss
- excess
- the part you pay on any claim (deductible)
- premium
- yearly price of the cover
2 · A worked example
Phone cover: $300.00 loss, 10% chance, $60.00 premium: average payout $25.00, so you pay 140% more than it returns, and the loss is affordable: absorb. Liability or income cover on a $200,000 loss you cannot fund: the loading barely matters, protect.

What this tool can’t see
- Probabilities are estimates; use the best data you can find (insurer, regulator, claims statistics).
- Check exclusions: a policy that does not pay when you need it has no value.
- Some insurance is compulsory or required by a lender: this tool does not replace those rules.
