After reading Jim Hagerman's paper, "Calculating Optimum Snubbers" and working my way through the formulae several times, I figured it would be easier to put it all on a spreadsheet rather than getting the calculator out every time! I haven't been able to find anything suitable on the web so I put this together.

I've checked it with his figures and it looks accurate but perhaps someone with a more mathematical brain than me could confirm the accuracy. Also, I did the spreadsheet originally in Libre Office .ods format so the conversion to .xlsx is OK but isn't protected and the layout is slightly off. Not a major problem but feel free to tinker with it and format it properly for Windows.

Attached are links to the spreadsheets, the original article plus an alternative method of calculating resonant frequency.

Hope you find these useful and any constructive feedback is welcome.

Above calculators now updated to include drop down lists to enable data to be entered in different units. Also, .xls file added below for older versions of Excel.
