FireCalc-same input, different results?
Just joined the forum and this is my first post. I have been using firecalc but I noticed that when I input the exact same input, I get different results. For example, I enter Start here - Spending-$122,000, Starting amount $2,183,443, 40 years. Other income - SS of $28,536 starting 2026. Not Retired - Retire in 2026. Spending models-Inflation using CPI, Constant spending power. Your Portfolio - Expense ratio of 0.7%, Random performance with portfolio return of 7.89%, SD of 15.56%, Inflation at 3%.
I have gotten the following "success" results with this input - 83.9%, 53.6%, 94.8%, 90%. What the heck am I doing wrong? Thank you in advance.
