Phased Drawdown Calculator

Hi all
One of our advisers has asked for a Phased Drawdown calculator, and apparently the M&G Retirement Modeller doesn't show what he needs - any suggestions?
I think he's looking for a table/graphic that shows the accrual pot reducing over time and the FAD pot growing.
Many thanks

I would be tempted to build this in excel and create a chart from the output.
It shouldn't be too difficult. I'm not aware of any calculators that will model this, as most will assume phased DD is using 100% of what's taken from the accrual pot.
If you are using a decent cashflow modelling tool, you could show this in the charts/tables by setting the correct withdrawal. We use Voyant and it would show the amount coming out of one pot and into the other.
