CDS swap Rate and valuation

I remember calculating interest rate swap rate during level 2… Any idea about how to calculate CDS swap rate …I will really appreciate this…Maybe someone has a handy excel tool

Not sure what you’re asking. CDS rates aren’t calculated, they’re observed – they are market-clearing prices. Markit is a goood source.

ISDA provides an excel add-in and I think there’s some linked documentation from markit which addresses swap rates. It was JPM’s model iirc. Never used it though, so can’t be much help beyond that.

thanks guys
