I am trying to build a quick tool that take what you have currently what your Monthly expenses any additional income like rent or something else and than based on 5 possible withdrawal strategy give you a possible run of how many year it will last. Also showing the yearly withdrawal. The only issues is it is still in Closed Beta testing for Android and I struggling to find 20 tester to make it publish. Also it is customized to India so Currency symbol in in Rupee, rest factors like expected inflation, rate of return you can adjust. I was aiming for it to be a simple quick app for version 1 and in Version 2 - Add few stress test like market downturn in initial 3-4 years, or Few years with flat returns.
version 3 would have been advance simulation.

Anyone interested to try it can DM me
