$300 Budget Auction

Joined an Auction league for the first time this year. I plan on using the UDK Auction cheetsheet. how much should i adjust the prices to account for the extra $100 budget?

It will be a percentage change. If Player A is $60 for a $200 budget, that would account for 30% of your budget. When you have a $300 budget, you should be able to expect to pay around $100 for Player A.
