Our TTL calculator computes total vehicle purchase costs by applying your state's sales tax rate to the taxable amount (vehicle price minus trade-in), then adding mandatory title and registration fees plus dealer documentation charges. The calculator uses standard automotive finance formulas to provide accurate out-the-door pricing and show exactly how trade-ins reduce your tax burden.

State-by-State Fee Variations

Vehicle TTL costs vary dramatically by state. Some states have low sales tax but high registration fees, while others have high tax but low fees. Understanding your state's structure helps you budget accurately. Registration fees may be based on vehicle value, weight, age, or a flat rate. Some states charge annual registration, while others offer multi-year options. Always verify current rates with your state's DMV as fees change periodically.

• Sales tax: 0% (OR, MT, AK, DE, NH) to 10%+ (CA, some local areas)
• Title fees: $15-$300 depending on state (most $50-150)
• Registration: Flat rate, value-based, or weight-based (varies widely)
• Documentation: $85-$995 (some states cap, others don't regulate)
• Trade-in credit: Reduces sales tax in most states (not all)
• Out-of-state: Pay tax/register in home state, not purchase state
