What does Co-Insurance mean?

It is a settlement between the insurer company and the policy holder, where they basically share the risk degree under the terms set by the company itself. It generally states that the policy holder will pay for costs pertaining to a defined percentage, but certainly the deductibles are being paid separately.

Co-Insurance explained

To exemplify it, if the deductible to a life insurance costs €400 and the coinsurance plan is of 70/30, this means that the percentage the policy holder is responsible for is of 30% plus paying the deductible. This means that the insurance company takes over responsibility for the remaining 70% of costs. It is a general rule with coinsurance plans that the policyholder cannot be made responsible for more than 50% of the costs.
