Payback Period

The time it takes for each individual level of the Rupie Mine to break even, or pay itself off, (does not consider earnings from any other level) can be calculated with the following formula:

PaybackPeriod = Cost/(Limit/6 hrs) + max(BuildTime-6 hrs,0)

The first term in the formula calculates the time it takes to cover the cost of the upgrade at that level's income rate. The second term accounts for the time period where potential Rupies are lost because they cannot be collected during construction. Since this only happens when the build time exceeds 6 hours, the second term rejects negative numbers and only keeps zero/positive numbers.

Note that the total Payback Period (last entry in the column, 18.26 Days) is assuming that each upgrade begins at the moment the previous level has payed itself off. It is possible for the mine to break even faster than 18.26 days if the early level upgrades are started as soon as the previous one finishes, or by spending Wyrmite/Diamantium to speed up the process.
