There are a lot of variables in play so a perfect answer isn't possible, however, calling 18-24 months BS is almost certainly wrong. 18-24 months sounds like the ideal answer. Note that you can spend $8k/month or you can spend $2k/month, depending on where and how you want to live while you're founding your startup. The nominal dollar amount could be a huge range. You could also reduce the dollar amount of savings you need by the revenue in your MVP - if you're making $1k/month on a software startup you'll probably be able to net that against your monthly spend, even if most of that $1k/month is currently going towards fixed costs. The difference between an MVP that generates revenue and one that does not is enormous.
