I’m trying to get my head around a correct formula for calculating ROI (annual).

As an example I’ll use Arctic coin (ARC).

At the time of my writing, these are the values for ARC (source = masternode.online):

- # of master nodes = 1,326
- difficulty 6974.541545346924
- ROI = 10.91 (this is the value that I should get from the formula)

From https://arcticcoin.org/en-EN/mining-pos , this is the formula for calculating ROI :

Per day = (n/t) * r * b * a
ROI (return on investment, in year) = ((n/t) * r * b * a * 365)/1000, where 


n - the number of personal active Goldmine (masternode), we’ll use 1 master node for this example

t - the total number of Goldmine (# of masternodes)

r - the current block reward 

b - blocks in an average day 

a - the average Goldmine payment

a is 45% (from the coin specs)
b is 576 (from the coin specs block generation = 2.5 minutes (150 seconds) so 86400 (seconds in a day) / 150 = 576)
r is apparently 2222222/(((Difficulty+2600)/9)^2), so plugging difficulty into the formula 2222222/(((6974.541545346924+2600)/9)^2) = 2094.459943449576

So the final formula ((1/1326) * 576 * 0.45 * 2094.459943449576 * 365)/1000 = 149.43639994711725

Waaaaaaaaaay out of 10.91 from above. What am I doing wrong ?

My other question is - is the above formula universal for all masternode coins ? I know that the block generation time and masternode reward percentage varies across coins, but could it be generally used for all coins ?

Thanks.

I see, Coin support masternode price changes fast, Masternode ROI calculation only at the present time, not count when the number of nodes increase or decrease (number of nodes increase or decrease greatly affect the amount of coin received)

When the people of the world will get that covid was intentionally released to frame china, steal the election from trump, assure massive bail outs and foster the forced vaccination agendas...they will forget, like 911, wmds in irak, uss liberty or pedogate.
