Deduct until last positive number remaining

[krismtx]

Thanks in advance!
I hope I can explain my question adequately:
I have a list of amouonts that are being deducted from 100,000. I woul
like to deduct until I get the "positive remainder". I do not want
negative number.

*$100,000.00* Amounts to be deducted Declining total

first $5,000.00 $95,000.00 $5,000.00
next $15,000.00 $80,000.00 $15,000.00
next $25,000.00 $55,000.00 $25,000.00
next $35,000.00 $20,000.00 $35,000.00
next $45,000.00 -$25,000.00 *$20,000.00*
*$100,000.00
