Batch editing and calculate numeric values

I have this situation: in my catalog there is a numeric for the insurance value. Last year, for a specific artist, the value of insurance has increased by 20%. The problem is that this artist has 200 works and the value of insurance is diferent for each one. Is there any way to perform a batch-edit and automatically increase 20% for each value?
Thanks a lot!
