What does the dream actually cost?

Dealer quotes hide the money factor, the residual, and the fees inside one monthly number. These calculators take that number apart — across 36 models from Porsche to Rolls-Royce.

Each one uses the same standard formulas a leasing bank uses — no rounded marketing math.

The same discipline, beyond the garage

Compare market premium and holding cost for collectible watches, or model the crew, dockage, fuel, and depreciation behind yacht ownership.

Why exotic car math is different

Residuals swing wildly

A G63 residualizes above 70% while an i7 sits near 42%. On a six-figure car that spread is worth thousands per month — more than any negotiation on price will ever recover.

Rate is charged on the whole car

Lease interest applies to the capitalized cost plus the residual, not just the amount you use up. On expensive cars the finance charge often exceeds the depreciation itself.

Running costs are not a rounding error

Insurance and maintenance on a supercar can exceed $12,000 a year. A payment comparison that ignores them will point you at the wrong car.
