DUI Fine and Penalty Cost Estimator
Estimate the total financial impact of a DUI conviction, including court fines, legal fees, insurance premium increases, license reinstatement, ignition interlock, and other associated costs.
Formula
Total DUI Cost = Court Fine + Court Fees + Attorney Fees + License Reinstatement + SR-22 Insurance Increase + Ignition Interlock Device + DUI Education + Treatment + Towing/Storage + Bail/Bond + Probation Fees
- Court Fine: Base Fine × BAC Multiplier — Base: 1st=$1,000 / 2nd=$2,500 / 3rd=$5,000; BAC multiplier: Standard=1.0×, Aggravated=1.5×, Extreme=2.0×
- Court Fees: Court Fine × 2.5 (penalty assessments, surcharges, victim funds)
- Attorney Fees: Public=$0 / Private Basic=$3,500 / Experienced=$8,000 (×1.5 for felony)
- SR-22 Insurance: (Annual Premium × Increase Rate + $25 filing fee) × SR-22 Years — Rate: 1st=80%, 2nd=110%, 3rd=150% (+20% for extreme BAC)
- IID Cost: $150 install + ($80 lease + $20 calibration) × Months
- Probation: $75/month × 12–36 months depending on offense number
- Towing/Storage: $150 flat tow fee + $50/day storage
