The premium comes neither from the law nor from any official table: copy it from the bank's offer and from a quote you request elsewhere. The spread increase is the discount you would lose. Leave it at zero if the discount is not tied to the insurance.

Sampled table; the total cost adds up every year of the term.
The premium rate also rises with age, which this calculation does not model: the totals are a floor. The comparison between two offers still holds, because age loads both of them.
