What Makes a Good Lease Deal? The 1% Rule

The reason lease forums obsess over deals is simple: most people genuinely can't tell whether a quoted lease is good. The advertised monthly payment is designed to look small, the costs are scattered across three other numbers, and there's no sticker price to compare against. Here's the math that cuts through it.

The only number that matters: effective monthly cost

A "$299/mo" lease with $4,000 due at signing is not a $299 lease. Spread that drive-off across a 36-month term and you're really paying:

effective monthly = monthly payment + (due at signing ÷ term)
$299 + ($4,000 ÷ 36) = $410/mo

Every deal you compare should be converted to this number first. It's why our deal rankings sort by effective cost (including the broker's fee), never the advertised payment.

The 1% rule

Effective cost alone can't tell you if a deal is competitive - $410/mo is great for a $55,000 car and terrible for a $25,000 one. The community benchmark is the 1% rule: divide the effective monthly cost by the car's MSRP.

• Under 0.8% - exceptional. These deals get snapped up in days.
• 0.8–1% - a genuinely good lease.
• 1–1.2% - market rate. Fine, not special.
• Over 1.25% - you can do better, on this car or another.

So that $410 effective on a $55,000 MSRP is 0.75% - an exceptional deal. The same payment on a $32,000 car is 1.28% - walk away. One division tells you which.

Why some cars lease far better than others

The 1% rule has a quirk: it's much easier to hit on some models than others. A lease payment is built from three levers, and they vary wildly by manufacturer and month:

1. Residual value - what the bank says the car is worth at lease end. Higher residual = you're paying for less depreciation.
2. Money factor - the lease's interest rate (multiply by 2400 to get an APR). Manufacturers subsidize this to move inventory.
3. Incentives - lease cash, conquest rebates, loyalty offers. These come and go monthly.

When a manufacturer stacks a high residual, a subsidized money factor, and fat lease cash on one model, that car leases at 0.7% while a similar car across the street sits at 1.3%. This is why deal hunters chase the deal, not the badge - and why the best-deals board reshuffles constantly.

The numbers designed to distract you

• "Sign & drive" framing - $0 due at signing usually just rolls the drive-off into the monthly. Effective cost is unchanged; only the optics improve.
• Payment quoted on a stripped trim - the ad shows the base model; the car on the lot has $4,000 of packages. Always score the actual MSRP of the actual car.
• Discount off MSRP - "12% off!" means little if the money factor is marked up behind it. Effective cost catches what the discount hides.
• Mileage fine print - a 7,500 mi/yr lease should cost meaningfully less than a 12,000 mi/yr lease on the same car. If you drive 12k, a cheap 7.5k lease isn't cheap - it's a deferred overage bill.

A 60-second deal check

1. Add up everything due at signing. Divide by the term. Add to the monthly. That's your effective cost.
2. If a broker's involved, amortize their fee the same way.
3. Divide by the car's real MSRP. Under 1%? Good deal. Under 0.8%? Move fast.
4. Sanity-check the mileage allowance against how you actually drive.
