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 × Penalty Multiplier (+ collection fee)
Cities almost always use a tiered multiplier rather than daily interest, which is why the cost jumps on specific dates instead of creeping up. The schedule this calculator uses is the common pattern:
| Days since the ticket | Multiplier | What else happens |
|---|---|---|
| 1–30 | 1× | Payment window. Many cities also offer an early-payment discount in the first 10–15 days. |
| 31–60 | 2× | Fine doubles. |
| 61–90 | 3× | Fine triples. |
| 91–120 | 3× | A DMV registration hold is usually placed. |
| 121+ | 3× plus a 35% collection fee | Referred to a collection agency. |
- Base Fine: the amount printed on the ticket, typically $25 to $500 by violation and city
- Penalty Multiplier: what the unpaid fine is multiplied by at each tier
- Collection fee: agencies charge a percentage on top, commonly around a third
Your own city’s schedule will differ, sometimes a lot. The back of the ticket prints the real dates and amounts, and that beats any estimate.
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. You find the ticket in the glovebox at day 45.
- Day 1–30: $75
- Day 45, so in the 31–60 band at 2×: $150
- Day 61 onwards at 3×: $225
- Day 121, plus the 35% collection fee: $251.25
Paying today costs $150. Waiting 16 more days costs another $75, which works out to roughly $4.70 for every day you leave it in the glovebox.
Two things worth knowing. The penalty clock usually pauses the moment you contest in writing, so an appeal you are unsure about still buys you time at no risk in most cities. And the escalation stops after the collection tier, but the debt does not: the registration hold stays until it is paid, which is how a $75 meter ticket ends up blocking a car sale two years later.
