- µ (mu): mean percentage
- σ (sigma): variance
- t: time period
- v: Initial value
The extension to the regular calculation uses: m: Value increase per time period (in my case monthly value) breaks: Quantile breaks to calculate the bounds
Code to calculate the values:
Applying the values:
- mu: 0.05 (or 5%)
- sigma: 0.1 (or 10%)
- initial value: 7000
- monthly increase: 100
- time period: 6 years
results in the following chart:
The code is available from Github. It ships with a Swing GUI to enter values and to draw a chart based on the calculation. https://gist.github.com/mp911de/464c1e0e2d19dfc904a7
