Hi Monique,
Although I didn't get a reply as to whether my calculation is correct, I believe my understanding is accurate. The deductible is only applicable when the property is insured at 80% or higher. It appears that the only time it would have an impact is if the LOSS is less than the coverage limit, just like my example below:
Loss $90,000-Deductible $5,000=$85,000+$7,000 Debris removal=$92,000 payable
The question however, shows a TOTAL loss. In this case that is $125K. You subtract the $5K from that comes to $120K BUT the coverage limit is only $100K so really the deductible has no impact. For me it's easier to determine first if it's covered at 80% or more. If yes, you apply deductible and subtract from the loss, BUT if the remainder ($120K) is higher than the coverage limit, the ignore the deductible. In this case it was $100K that's payable + $7K of debris removal.
If not insured at 80% or more, THEN you use the coinsurance formula which is the loss x coverage amount divided by the value x coinsurance percentage.
In this problem, if the coverage limit were $70K which is less than the 80% then you ignore the deductible and use the formula above like this:
Loss $125,000 x Limit $70,000 divided by Value $125,000 x 80% = $87,500.
By meeting the coinsurance requirement, they get the full $100K limit + $7K debris removal. By NOT doing so, they get $87,500 + $7K debris removal.
I hope I'm right and if so, I hope that clarifies this a little.
