RetireJapan

Any recommendations on retirement planning software? Preferably with a decent free/demo version?

I found several online, but they're all too simplistic for me. I'd like to be able to specify things like declining spending with age, and different tax-rules for different buckets of money.

I have several spreadsheets I use, but wouldn't mind a second opinion or two.

Any suggestions?

I just use one called Excel.

Google Sheets and journalling for me.

I work best with a napkin or the back of an envelope.

I carve it in to the back of my hand with a compass.

Through my training as a Mentat and a Zensunni Philosopher all my planning is internalized and perfectly logical.

(Not really constructive, and I'd like to apologize for that, but I wanted to have it on record that your suggestions have been properly noted.)

Played around with a few, haven't found the gold standard (for free) yet, but happy to share what I saw:

found Projection Lab very impressive (but didn't pay): https://projectionlab.com/?ref=rberger

The embedded one also looks helpful: https://www.financialmentor.com/calcula ... calculator

A bit old, but found this to be very inspiring: https://www.flexibleretirementplanner.com/wp/

Easy, as in an excel sheet: https://www.vertex42.com/Calculators/fi ... ators.html - scroll to Retirement calculator.

General remark: just calculating with "japo-dollars" (=JPY -two zeros) to overcome the currency difference.

I use my own excel sheet for basic scenario calculations based off the 4% rule, but more than interested to learn more from others.
