What is the current worth of your passive income?

The calculation is based on the idea that a source of passive income is worth as much as it would profit until the source is deprecated, considering a decline over time (the decline in the graph).

In this calculation this is estimated by providing a lower limit where the profit is 'insignificant' (L in the graph). The accumulated income until in that happens is the same as the sum of the income reached until that time ('sum of the columns' in the graph).

You can also provide a rebate or margin (similar to raising, or lowering, the entire graph).
