Formula and Logic
The calculator starts with the base unpaid amount plus materials costs. It then applies the statutory interest rate for the selected jurisdiction, calculated on an annual basis and prorated for the days unpaid. Finally, it adjusts the total based on the lien type multiplier (e.g., mechanic's lien, bond claim, or stop notice).

Additional Guidance
Keep detailed records of all work performed, materials supplied, and communications with the property owner. Consider sending a formal demand letter before filing a lien, as this may resolve the issue without legal action. Always check for lien deadlines, which can be as short as 60-90 days from last work or material supply.
