Concerning Risk Of Ruin of 5%

I'm hoping someone can help me out. I'm trying to find out what size bankroll I will need in order to play with a 5% risk of ruin. I'm not sure how to do it or I'd do it myself.
I play a 6 deck shoe and the casino cuts out one deck-sometimes a deck and a half. Rules are DAS, DA2, LS. As I understand it playing with a 5% ror means I have a 5% risk of losing all my money and a 95% chance of doubling my bankroll before that occurs. I play $5.00 and increase my bets to $15.00-$25.00-$40.00 and $50.00. So I'm using a 1-10 spread using Renzeys' Kiss III count. I'm thinking I'll need a bankroll of $5,000. Thank you one and all!
