How much do I need monthly to become a millionaire?

It depends on your current balance, time horizon and return assumption. More time usually reduces the required monthly amount dramatically.

Does this account for inflation?

No. Use an inflation-adjusted return assumption if you want a rough real-growth estimate.

Does this include taxes or fees?

No. Results are before taxes and fees.
