Private planning calculator
Estimate how much extra work is sitting outside your fixed fee.
Enter a typical project fee, planned hours, and recent out-of-scope requests. The calculator estimates unbilled extra hours and the effect on your effective hourly rate. It is only arithmetic on numbers you provide, not an audit, forecast, or legal/financial advice.

This is not a prediction that a client would approve or pay. It is a planning illustration from your assumptions.
This is a private planning estimate, not an audit, legal advice, financial advice, pricing advice, or a forecast.
