As of patch 2.0.1 paragon levels are no longer capped. How can I figure out how much xp it takes per level of paragon?

Pre 2.0.1 patch:

Blizzard announced that there would be 100 additional "Paragon" levels after a player reached level 60. I'm not sure if they announced exactly how the increase in XP would work, but I was wondering if anyone knew the total amount of XP needed to get from Paragon level 0 to 100? A formula would also be helpful.

(The only detail I was able to uncover from Blizzard was that the first paragon level would be roughly the amount of xp it took to get from level 59 to 60)

Molster over at Diablofans made a spreadsheet which details the amount of experience required to get Paragon levels with the new Paragon 2.0 system:

It is worth noting that these levels are in addition the 60 (70 in Reaper of Souls) character levels.

There is also this chart, which shows the experience needed for each level.

So, you need 10,454,400,000 experience total, from level 60.

From the calculations in this thread, starting from level 60, with full 75% NV buff, to get 100 paragon will require killing approximately 1,327,000 lvl 63 monsters, or 6,534,000 Inferno Hulking Phase Beasts, or 8,167,500 Inferno Dust Imps.

Happy hunting!

As of patch 2.0.1, there are no longer a cap to paragon levels. The amount of EXP required to advance to the next paragon level, before level 1488, is calculated by the following formula:

EXP required = Level * 1,440,000 + 5,760,000

For example, to get to level 18, you will need 18 * 1440000 + 5760000 = 31680000 EXP (from level 17).

However, once you hit paragon level 1488, it would require more than 2,147,483,647 EXP to advance to the next level according to this linear increment. Since 2,147,483,647 is actually the maximum value of an integer typed variable in computer programming, the EXP requirement will stop its increment after level 1488. That is: You will need 2,147,483,647 EXP to advance one level after level 1488.

We still have to find some sort of official formula. Charts and tables out there seem to rely on people playing the game and then interpolating the points. Even the diablofan article seem not to give a formula. However the formula provided as

EXP required = Level * 1,440,000 + 5,760,000

Seems to work. As for the level 1488 cap, this is NOT a limit for 64bits integers and since the cumulative experience goes far beyond the 32bit limit I guess there is no such cap.

Anyway we would need somebody at Blizzard to confirm or infirm our assumptions.
