Not recursive, but iterative.
For instance this way:

Code:

01 ENTER
02 0
03 R/S
04 %
05 CHS
06 LstX
07 +
08 +
09 GTO 03

Enter the inital price [R/S], then the first, second, third, ... percentage [R/S].

1000 [R/S] => 0,00   no discount yet
  5 [R/S] =>   5,00   5% discount so far
10 [R/S] => 14,50    now it's 14,5%
15 [R/S] => 27,33    and finally 27,3%

[%] => 273,25   discount
[–]  => 726,75   final price
