Short answer: take your pre-tax monthly payment, add your total due at signing divided by the term, and compare that effective cost to the car's MSRP. Hitting 1% or better is a genuinely strong deal today. But the 1% rule is arbitrary — it doesn't apply to luxury leases, and it should never include sales tax, registration, or government fees.

The 1% rule is an arbitrary shortcut, not a rule. It doesn't work for luxury leases and it should never include taxes or government fees. This calculator is a rough self-check, not an appraisal — it can't see your money factor, residual, dealer add-ons or which incentives you qualify for. That's what the free broker review is for.
What the 1% rule is — and isn't
The 1% rule is an arbitrary shortcut, not a real formula. It can be useful as a quick gut check on a mainstream car, but it does not apply to luxury leases and it should never include taxes, registration, or government fees. A BMW or Mercedes lease can be well above 1% and still be competitive. Always compare the actual structure — selling price, money factor, residual, and incentives — not just a percentage.
A payment is an output. These four inputs are what actually make a lease good or bad — and they're the same four we check on every deal review.
How far below sticker did you actually buy? A strong deal starts with a real selling-price discount, not a low payment engineered by a big down payment. Ask for the selling price in writing before anything else.
The money factor is the lease interest rate. Dealers are allowed to mark it up above the bank's base rate, and it's the single most common place a quote quietly gets worse. Multiply the money factor by 2,400 to see it as an APR.
Loyalty, conquest, first responder, college grad, EV and regional cash — these change by brand and by month, and they don't apply themselves. If a rebate you qualify for isn't itemized, it probably wasn't used.
Not 'first payment only' — every dollar you hand over: down payment, fees, drive-offs. Spread that across the term to get your true monthly cost. A $0-down quote and a $4,000-down quote can be the same deal or wildly different ones.
Ask for the worksheet — a real one, not a payment quoted over the phone. Here's what each line means and what to look at.
California is one of the most competitive car markets in the country, which cuts both ways. There are enough franchise dealers in Southern California that a car in stock 20 miles away can be priced very differently from the one at the store nearest you — so a quote that looks fine in isolation can still be beatable.
Lease tax here is charged on the monthly payment rather than the full vehicle price, and your local rate varies by city, so two identical deals in Orange County and Los Angeles won't show identical payments. Compare pre-tax structure, not just the number at the bottom.
EV leases deserve their own look. Manufacturers put aggressive EV lease cash and subsidized money factors on electric models, and several brands add regional, conquest or loyalty cash on top — which is why a well-structured EV lease in California often lands at a very low effective cost compared with a gas car. If your EV quote looks high, ask exactly which EV incentives were applied.
Programs change monthly. A deal that was excellent in February can be ordinary in March on the same car, because the money factor, residual and incentive stack all reset. That's the main reason a quote is worth checking against current numbers rather than against what a friend paid last year.
A calculator can't see your money factor, whether the residual is right, which incentives you qualified for, or what that $1,295 line item actually is. That's the part we do by hand — free, statewide, on brand-new cars, lease or finance.
