A - You will notice when running the simulation that real money is calculated based on RPI.
You can adjust the assumption for CPI by visiting Preferences (the cog icon, top-left) > Plan Preferences (on the right side of the screen) > expend Default Inflation / Growth Rates > edit CPI % > click the Apply button (bottom-right). Return to the Let's See charts and rerun the simulation.
Bear in mind that adjusting the CPI be used to escalate final salary and annuity payouts, when this type of indexing is selected. If your plan contains final salaries and/or annuities that you have set for escalation based on CPI, please be aware that adjusting the CPI preference will also affect future payouts from these income sources.
