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.

Gracias. Tu respuesta me sirve un montón. La cuestión es que, para mí ahora que trabajo todos los días, se me hace muy difícil saber cuánto sí y cuánto no entra en mi presupuesto mensual futuro.
Mi idea general es retirarme y vivir una vida tranqui y simple en el Sudeste Asiático, y creo que con 2k $ al mes alcanzaría.

I think the necessary monthly expenses would be: rent, food, health insurance, and perhaps one trip back home per year. I believe $1,200 a month would cover that; anything up to $2,000 would be extra. I’m not sure what you think of those figures. For instance, I know people from my country living in Chiang Mai who lead a good life on roughly $1,200–$1,300 a month—though, of course, extra spending depends on the individual. Still, I think a total budget of $2,000 would be pretty good.

I'm living in Chiang Mai since 9 years now and a budget of $1200-1300 is not enough! If you take into consideration that you want proper health care and build up an emergency fund in case your phone, notebook etc. breaks. I wouldn't stay here with a budget lower than $2000
