How Much to Lease an AMG GT in 2026

Two AMG rows, and what they assume

Affalterbach builds the family's loud children, and this site models two of them: the AMG GT coupe and the AMG C63 S E Performance sedan. The G63 is the third AMG on the site, but the G-Class has its own guides and its own gravitational field.

I do not invent a monthly for a GT 43, a GT 63 PRO, an SL, or an E63. Those are not calculator rows on this site.

All figures assume 36 months, 10,000 miles a year, a 0.0027 money factor (6.48% comparison shorthand, not loan APR), 10% cash down, capitalized fees, cash fees, and 7.25% tax on the payment. Due at signing is the calculator's 10% down plus fees and the first month. Data snapshot: August 2026. Not dealer quotes.

• AMG GT. MSRP $148,000. Residual 55% ($81,400). Market adj. −5%. About $1,959 a month. Due at signing $17,959. Cash over the term $86,508.

• AMG C63 S E Performance. MSRP $89,000. Residual 50% ($44,500). Market adj. −9%. About $1,195 a month. Due at signing $11,295. Cash over the term $53,133.

Official stickers, one site row apiece

Mercedes-Benz USA's AMG GT coupe page, fetched 30 August 2026, prints five 2027 starting prices: GT 43 from $108,850, GT 55 from $137,450, GT 63 from $184,000, and GT 63 S E Performance and GT 63 PRO both from $205,000. No lease figure is printed.

This site's one AMG GT row is $148,000 — between the official GT 55 and GT 63 stickers — with a 55% residual, producing about $1,959 under the assumptions above. The figure is the Luxemetry model, not an MBFS program, and I do not scale it to fake a GT 43 or a PRO payment.

The C63 row is $89,000 with a 50% residual. The twin-turbo V8 four-door this car replaced is the ghost at every C63 negotiation, and the 9% market discount is the séance.

Five official GT stickers, one modeled row. The residual belongs to the row, not the trim walk — a $205,000 GT 63 S E Performance does not lease off this page's math.

The market grades the cylinder count

A lease is a rental of depreciation, and the two AMG rows depreciate by ideology. The V8 GT holds a 55% residual with a modest 5% discount — sports-car-normal numbers, in line with its 65% three-year retention. The four-cylinder hybrid C63 holds 50% with a 9% discount, and its three-year retention models at 58%.

Compare the C63 to its own rival: the BMW M3 Competition row — six cylinders, no hybrid apology — holds 55% and leases for about $1,153 on a $3,000 lower sticker. The C63 makes 671 horsepower to the M3's 503 and still loses the residual argument by five points. The market is not paying for output; it is paying for the idea of the car, and the idea got smaller.

The GT's own comparison set is kinder. Against the Porsche 911's fearsome 63% residual it gives up eight points, but the money runs the other way — the 911 leases at about $2,162 to the GT's $1,959, roughly $203 a month more on a $27,000 higher sticker. Only as a share of sticker does the GT come out behind: 1.32% a month against the 911's 1.24%. Against the BMW M8 at 47%, the GT is simply the better-held car: $1,959 versus $2,008, near-identical stickers.

• AMG GT vs BMW M8 (this site). $148,000 vs $146,000 MSRP; 55% vs 47% residual; about $1,959 vs $2,008 a month. The residual decides it.

• AMG C63 vs BMW M3 Competition (this site). $89,000 vs $86,000 MSRP; 50% vs 55% residual; about $1,195 vs $1,153. More horsepower, weaker hold.

• The family freak. The G63 residuals at 72% and transacts over sticker. Same letters on the engine cover, different universe — see its own guide.

What three and five years actually cost

AMG GT: three-year retention 65%, a $51,800 loss on $148,000. Five-year ownership at 5,000 miles a year models at $112,274 — about $1,871 a month with insurance at $3,600 and maintenance at $2,700. Ownership models $88 under the lease; on a curve this balanced, the quote decides, not the doctrine.

C63: three-year retention 58%, a $37,380 loss on $89,000. Five-year ownership models at about $1,354 a month against the $1,195 lease — the lease wins, as it usually does when a residual starts with a five and the discount starts with a nine.

The C63's hybrid hardware adds a quiet ownership consideration the model prices at $2,500 a year in maintenance: a 6.1 kWh battery and an electric exhaust-gas turbocharger are wonderful until they are out of warranty, which is approximately when a five-year owner meets them.

What I do with a dealer quote

I agree the selling price as if I were paying cash — 5% off the GT and at least the modeled 9% off the C63; a car the market discounts, I discount. Then I ask for the five inputs: capitalized cost, residual percentage for this exact term and mileage, money factor, term, and mileage allowance.

I put those five into the lease calculator. If the formula and the worksheet disagree, a fee is in the deal I have not been shown. On AMGs I also ask whether MBFS is running a subvented money factor this quarter — performance-car support comes and goes with inventory.

These estimates use 10,000 miles a year. If I need more, the residual falls; buying the miles up front beats the excess-mileage bill at return. A large check at signing is prepaid depreciation, not equity.

Three desks: brochure, live row, methodology

I keep three sheets on this desk. MBUSA's AMG GT coupe page is for the 2027 starting prices I already quoted — $108,850, $137,450, $184,000, $205,000. Residual and money factor are not on that page.

The live AMG GT row is https://luxemetry.com/cars/mercedes-benz/amg-gt : $148,000 sticker, 55% residual, about $1,959 a month. The C63 S E Performance row on this same page is $89,000, 50%, about $1,195. Same 36-month, 10,000-mile, 0.0027 money-factor sheet as the rest of the site.

How those residuals are built is on https://luxemetry.com/methodology . If a dealer worksheet disagrees with the live row, a fee or a different residual is in the deal I have not been shown.
