In health insurance, it limits administrative costs and profits, while in homeowners insurance, it ensures adequate dwelling coverage to avoid penalties on claims.

Is it better to pay a copay or coinsurance?

Neither copay nor coinsurance is inherently "better"; it depends on your health needs, but copays offer predictable flat fees for routine care (like doctor visits), making budgeting easy, while coinsurance (a percentage of the cost) shares expenses for bigger services (like surgery) after your deductible, which is better for lower overall usage but less predictable. If you use healthcare often, lower copays/coinsurance with higher premiums might save you money; if rarely, higher copays/coinsurance with lower premiums could be cheaper.
