(Ex.) John brings us his product on 11/2/14 and decides to pick it up on 3/15/15 he will automatically be charged .15 cents till the end of the year, then 5 cents per month there after...that 5 cents gets prorated by the day for that month...so if his product is only up here for 15 days he would only get charged 2 1/2 cents, I would like a formula that allows me to enter the date the product was brought in and enter a date when the product was picked up, and it will spit out how much they accured in charges....I hope this makes sence....Thanks for any help you can provide
