Auto Loan Early Payoff

Out-the-Door Price Calculator
Turns a negotiated vehicle price into the true out-the-door total: sales tax (with or without trade-in credit), dealer doc fee, registration, and add-ons — and the markup over sticker.
Best when comparing dealer quotes or budgeting the real cash needed.
- Calculator →
Negative Equity Calculator
Shows whether you owe more than your car is worth, how much negative equity rolls into a new loan, and the extra payment and interest that carry-over creates.
Best when trading in a car you still owe money on.
- Calculator →
Lease Buyout
All-in cost to buy out your lease at the contract residual (price + tax + fees) compared to the car's current used-market value. Positive equity ⇒ buy; negative ⇒ return.
Best at lease end when deciding whether to keep the car.
- Calculator →
Lease Payment Calculator
Builds a lease payment the way the dealer does — depreciation plus the money-factor rent charge plus tax — and splits out exactly how much of each payment is interest.
Best when checking a lease quote or building your own deal.
- Calculator →
Lease Mileage Overage
Projects whether your real driving blows the lease's mileage cap, the excess charge it triggers at turn-in, and whether buying extra miles up front is cheaper.
Best when you drive a lot and are mid-lease or signing one.
