Hello 
According to our information 20- 30% is a good value. 
This was also the outcome of a research of a German lead free task force.

        Subject:  [LF] lead free solder paste

        hello everyone !

        I'm searching for informations about the solder paste overcost
induced by
        lead substitution. (for SnAgCu and SnAg solder pastes)
        Some suppliers estimate it about 20-30 % of the price.

        Could anyone help me ?

        I feel that if someone has done his homework and gone leadfree, he's
        hardly likely to have 2 production lines for the same product. The
        incremental operational savings by staying with 63/37 when he is
also
        using lead free are hardly likely, IMHO, to be significant (probably
        negative), after deduction of the amortisation of the incremental
        capital costs. And think of the nightmare of servicing, with
potential
        mix-ups between the two types.
