Capitalized Cost Calculator

Three capitalized cost numbers, and which one sets your payment

Every closed end car lease has a beginning balance. The industry calls it capitalized cost because the leasing company is capitalizing, meaning booking, the value of the vehicle plus whatever else you agree to pay over the term. Regulation M, the Consumer Financial Protection Bureau rule at 12 CFR 1013.4, requires the lessor to disclose that balance in three pieces.

Gross capitalized cost is the starting figure. Capitalized cost reduction is everything you hand over at signing that lowers it. Adjusted capitalized cost is the difference, and it is the number the finance office uses to compute your base payment.

The gap between adjusted cost and residual value is depreciation. Divide it by the term and you have the depreciation part of the monthly bill. The rest is rent charge, which is interest by another name. This page covers the cost side, and the rent charge gets its own section below because dealers quote it as a money factor rather than an APR.

Gross capitalized cost: the line you can still negotiate

Gross capitalized cost is not a single price. It is a stack of items, and only some of them are fixed. The agreed value of the car is the biggest and the most negotiable. Acquisition fees, documentation fees, dealer add-ons, capitalized taxes and any balance rolled over from a prior lease all sit on top.

That stack is why two leases on the same car can differ by thousands. A $695 acquisition fee and a $600 doc fee add $1,295 before the first payment. Protection packages and service contracts can add another $1,500 to $3,000, and those products carry their own margin.

Ask for the itemization in writing. Regulation M gives you the right to a written itemization of the gross capitalized cost before you sign, and the Federal Reserve's leasing guide makes the same point: if the lease does not explain what the amount includes, ask.

Cap cost reductions: cash, trade equity and rebates

Every dollar of cap cost reduction lowers the balance the lease amortizes, so it cuts both the depreciation and the rent charge. On a 36 month lease with a money factor of 0.00125, $1,000 down removes $27.78 of depreciation and $1.25 of rent charge each month, or $29.03. Over the term that is $1,045 saved for $1,000 spent.

The return is small, and the risk is not. A cap cost reduction is not a security deposit. If the car is totaled or stolen in month three, gap insurance covers the difference between the lease balance and the actual cash value, but it does not return your cash. Many leases include gap coverage at no extra charge, so confirm that in writing before you rely on it.

Rebates are the best form of reduction because the money comes from the manufacturer, not your bank account. Trade equity is second: most states tax a purchase on the price minus the trade, though lease tax rules vary by state. Cash is last, and a large down payment on a lease buys less than most drivers expect.

The FTC guide to financing or leasing a car makes the same argument from the other direction: a low monthly payment is easy to manufacture, and the total cost is what matters.

Adjusted capitalized cost and the depreciation charge

The arithmetic is short. Subtract total reductions from gross capitalized cost and you have the adjusted figure. Subtract the residual from that, divide by the number of months, and you have monthly depreciation.

Using the numbers above: 40,695 minus 7,000 is 33,695. Minus a 22,400 residual leaves 11,295 of depreciation, and 11,295 divided by 36 is 313.75 a month.

Term length changes the monthly figure without changing the car. A shorter lease spreads a smaller depreciation amount over fewer months, and a longer lease does the opposite with a lower residual. The table holds the adjusted cost at 33,695 and moves only the residual and the term.

Notice the pattern: the 48 month lease has the lowest monthly depreciation and the highest total. That is the trade you make every time you stretch a term to fit a budget. The Regulation M text defines depreciation and amortized amounts exactly this way, as the difference between adjusted capitalized cost and residual value.

Worked example: a $38,000 crossover over 36 months

Here is the full stack with a down payment, a trade and a rebate in play. The vehicle price is $38,000, fees are $1,295, and $1,400 of tax is capitalized. The buyer puts $3,000 down, trades a car with $2,500 of equity, and assigns a $1,500 rebate.

The chain is short: 40,695 - 7,000 = 33,695, then 33,695 - 22,400 = 11,295, and 11,295 / 36 = 313.75.

Gross capitalized cost lands at 40,695 and reductions at 7,000, so the adjusted figure is 33,695. With a 22,400 residual, total depreciation is 11,295 and the monthly depreciation charge is 313.75. Add a rent charge of 70.12 at a 0.00125 money factor and the base payment is 383.87 before monthly sales tax.

Money factor, rent charge and the fees buried in cap cost

Rent charge is the lease's interest. Dealers quote it as a money factor, a four digit decimal that converts to an APR when you multiply by 2,400. A factor of 0.00125 is 3 percent. The monthly rent charge is the adjusted capitalized cost plus the residual, multiplied by the factor.

On this lease that is 56,095 times 0.00125, or 70.12. Add it to depreciation and the base payment is 383.87. The same lease at a 0.00250 factor would carry 140.24 of rent charge, which is $2,524 extra over 36 months for the same car and the same mileage cap.

Fees are the other soft spot. An acquisition fee of $695 is common at many captive lenders but not universal, and it is sometimes waivable on a returning lessee. A doc fee is dealer revenue in most states. Add-ons such as paint protection, wheel and tire coverage and excess wear plans are priced at the back of the deal, after you have settled on a payment, which is exactly when they are hardest to refuse.

One more trap sits in the residual. A lease with a 65 percent residual has a smaller depreciation charge than one at 55 percent on the same car, but the buyout at the end is higher. Neither number is a discount. The residual is a forecast, and the lessor sets it to hit a target payment.

The other capitalized cost: perpetual cost in engineering economics

The same phrase appears in engineering economy textbooks with a different meaning. There, capitalized cost is the present worth of a project that repeats forever. For an asset with an initial cost P, an annual cost A and an interest rate i, the formula is CC = P + A/i.

A $50,000 asset with $4,000 of annual maintenance at 5 percent has a capitalized cost of 50,000 plus 80,000, or 130,000. The annual equivalent is 130,000 times 0.05, or 6,500, which matches the 4,000 of maintenance plus 2,500 of interest on the initial outlay.

That second number answers a planning question: what endowment would fund this asset forever. A car lease does not work that way, because the lease ends and the asset goes back. The calculator on this page uses the lease definition. If you need the perpetual version, the formula above is the whole method, and any spreadsheet will handle it.

Reading the calculator output

Five numbers come back. Gross capitalized cost is the sum of price, fees and capitalized tax. Total cap cost reductions is down payment plus trade equity plus rebate. Adjusted capitalized cost is the difference. Total lease depreciation is adjusted cost minus residual. Monthly depreciation is that total divided by the term.

What the calculator leaves out matters as much as what it includes. It does not compute rent charge, monthly sales tax, registration, a disposition fee at turn in, excess mileage at 15 to 30 cents a mile, or wear charges. A lease quoted at 313.75 of depreciation is not a 313.75 payment.

Use it to compare offers on the same car. If one dealer's adjusted capitalized cost is $1,800 higher than another's for an identical build, the gap is fees, add-ons or a worse price, and no money factor will hide it. Bring the worksheet to the desk and ask the finance manager to match line by line.
