Negotiate.. Just add 30% from your current salary. Then ask the interviewer how much do they want to offer.

If can negotiate between 15%-25% current increment is consider OK for me at least..

You already accepted the offer, whats the point of going to the interview with company B?

What you can do is negotiate the salary with company B without mentioning the offer letter from A.
(you will lose the power for negotiating if the company know how much others are offering you)

Later if they call you to inform that you get the job at B but with lower salary than A, reject the offer.
I think they will ask you why. Just inform them that you are going to accept another job offer at A because of the salary.
Do this only if you are going to go to A and got nothing to lose.

If they really want you maybe they will counter offer. If not they will only tell you good luck..
