One point I've not seen made (forgive me if I missed it) is the ability to fine-tune your tax liability if you withdraw monthly. This could be important, especially if you are on the edge of a higher tax bracket.Next year, we will have to begin taking funds from IRAs for actual living expenses. Based on that, we need to answer the same question as OP. Monthly or yearly? I'll let you know!
If you withdraw a full year of expected expenses and for some unforeseen reason have additional income in that year, you could end up paying an unnecessarily higher tax on the incremental income. Withdrawing from your IRA monthly will allow you to adjust your income if needed and better control your tax liability.
