How to use this estimate

Budget the mandatory column first: it is the amount you cannot avoid in year one. Everything in the optional column is a choice — you can be your own registered agent and draft your own operating agreement.
Only pay for expedited processing if a bank account or contract deadline depends on it; standard online filings are usually processed within days.
Put the recurring deadline on your calendar the day you file. Late penalties and loss of good standing cost more than the recurring fee itself.
