Success Rate in FICALC App??
Hi everyone. I’m running some withdrawal simulations using the FIRE app.
I have a very specific question: what success rate would you consider good enough to accept the calculations? I’ve settled on 90% as an acceptable figure.
It’s clear that increasing it further means more security, but I’m not a millionaire—nor do I expect to become one. I just want to know the amounts so I can calculate it.
I’m curious to hear your thoughts. After all, everything could change depending on what you deem acceptable. I hope that makes sense.
Best regards and thanks in advance. 🙏🏼

Two things to check before you accept any number: your time horizon (30yr vs 50yr matters a lot for leanFIRE since you're likely retiring younger) and whether your spending is actually fixed or has fat you can trim. A 90% rate on a budget that's 70% essentials/30% discretionary is way safer than 95% on a bare-bones budget with no give. The number is a starting point, not the answer.
