Calculate your net worth
Now that you have forecasted your savings and salary over time while taking career progression and inflation into account, you have constructed a time-series which you can use to calculate your cash flows, just like in Chapter 1.
For this example, all you need to do is subtract your forecasted monthly expenses from your forecasted monthly salary. The remaining cash flow will go straight into your savings account for each month.
You want to project your cumulative savings over time to see how effective your budgeting process will be given your projections.
salary_forecast and expenses_forecast from the previous exercises are available.
