Parking Ticket Fine Calculator
Calculate parking ticket total cost from base fine and days since issue.
Shows how a $65 ticket grows to $150+ unpaid with DMV hold and boot risk thresholds.
Parking ticket fines have two components: the base fine set by the jurisdiction, and late penalties that compound the longer you wait. Understanding the math helps you decide whether to pay immediately, appeal, or contest in court.
Total cost if paid late: Total = Base Fine + (Base Fine × Penalty Rate × Days Late)
Or for tiered penalty systems (most common): Total = Base Fine × Penalty Multiplier
Where:
- Base Fine — the original amount printed on the ticket (typically $25–$500 depending on violation and city)
- Penalty Rate — daily or weekly late charge, usually 1–3% per period
- Penalty Multiplier — many cities double or triple fines after 30, 60, and 90 days
- Days Late — calendar days from the due date shown on the ticket
Typical fine ranges by violation type:
- Expired meter: $25–$75
- No parking zone: $65–$150
- Fire hydrant blockage: $100–$300
- Handicap space violation: $250–$500
- Street sweeping: $40–$100
Appeal cost formula: Net Savings if Won = (Total Owed) − (Appeal Filing Fee)
Most jurisdictions offer free appeals. Some charge a $25–$50 filing fee. If your fine is $250 and you have a valid defense (illegible sign, meter malfunction), the expected value of appealing is almost always positive.
Worked example: Base fine: $75 (expired meter). Paid 45 days late. City doubles fine after 30 days.
- Original due: $75
- After 30 days unpaid: $75 × 2 = $150
- After 60 days unpaid: $150 × 2 = $300
By paying at day 45: $150 total. Waiting another 15 days would cost $300.
Key insight: Parking fines penalize procrastination severely. A $75 ticket becomes $300 in 60 days — a 300% increase in just two months. Pay within the discount window (usually first 10–15 days) whenever possible, or contest immediately in writing to pause the penalty clock.
