Sorry for the downtime last week since Jan, 6th 2019. Blizzard updated their API once again but the calculator should now run correctly!
When a Season ends your Paragon experience is rolled over to your non-Seasonal profile.
To calculate what Paragon level on your Non-Seasonal profile you will be when the current Season ends, simply fill either of the following forms and press the button.
The calculator's cap is 10,000 and is based on Diablofans' chart.
Fixed an issue which caused paragon levels greater than 2,000 to not be calculated correctly.
If Battle.net is down for maintenance, your level may appear as 0. If such problem occurs, use the form from above.
