Adjusted Lease Balance Calculator
Midway through a lease, what do you actually still owe? The adjusted lease balance is the remaining obligation after accounting for payments already made, plus any extra charges, and optionally adjusted for the asset’s depreciation. This adjusted lease balance calculator computes both the standard balance and the depreciation-adjusted variant, then compares the result against the vehicle’s current market value to show whether you hold equity or sit underwater. If you are weighing a buyout and need financing for it, our mortgage payment calculator shows how amortizing a buyout-sized loan compares with continuing lease payments.
Simplified model. Your lease contract’s early-termination section defines the exact adjusted balance formula (often an actuarial constant-yield calculation), which can differ from these figures.
Quick Answer
A $30,000 lease with $10,800 paid and $350 in extra charges has an adjusted lease balance of $19,550.00. The depreciation-adjusted variant at 10% is $17,630.00, and against a $22,000 market value you hold $2,450.00 of equity. Enter your contract figures above.
Key takeaways
- Standard adjusted lease balance = original balance – payments made + additional charges.
- The depreciation-adjusted variant reduces the remaining balance by the asset’s depreciation rate.
- Compare the balance to current market value: the difference is your equity (or negative equity).
- Real contracts often use an actuarial constant-yield formula; this tool gives the practical figure.

The two formulas, and when each applies
Search results for this topic split into two camps, and both are legitimate for different purposes. The simple form, used by general-purpose calculators, is ALB = original lease balance – payments made, with additional charges added back. The depreciation-aware form subtracts the asset’s depreciation from the remaining balance before adding charges: ALB = RB – (RB x d / 100) + N, where RB is the remaining balance, d the depreciation rate, and N additional charges. This calculator shows both, so you can see the range instead of picking one blindly.
Worked example: $30,000 lease, $10,800 paid
- Remaining balance: $30,000 – $10,800 = $19,200.
- Add charges: $19,200 + $350 = $19,550.00 standard adjusted lease balance.
- Depreciation variant: $19,200 x (1 – 0.10) + $350 = $17,280 + $350 = $17,630.00.
- Equity check: $22,000 market value – $19,550.00 = $2,450.00 of equity.

How the balance moves across the lease
Where the original $30,000 stands now
Bars are scaled to the original $30,000: 36% paid, about 65% still owed, and an 8% equity cushion against market value.
Using the balance to judge a buyout
The adjusted lease balance is the starting point of every buyout calculation. An end-of-lease buyout is generally the payoff (built from this balance) plus taxes and fees; an early buyout adds the remaining payments with adjustments. The equity figure is what matters most: positive equity means the car is worth more than you owe, and you can apply that equity to your next vehicle or capture it by buying and reselling. Negative equity means walking away is usually cheaper than buying. If you decide to buy and finance the amount, our mortgage payment calculator amortizes a buyout-sized loan so you can compare the monthly cost against your current lease payment.
Positive equity
- Market value exceeds the adjusted balance.
- Buyout can be profitable: buy, then resell or trade.
- Dealers will often apply it as a down payment.
Negative equity (underwater)
- The adjusted balance exceeds market value.
- Buying means overpaying versus the car’s worth.
- Returning the car at lease end usually costs less.
A note on your contract’s own formula
Many lease agreements define the adjusted lease balance actuarially, using a constant yield rate (the interest rate implicit in the lease, similar to an APR) compounded monthly. The simplified balance this calculator produces will be close for planning purposes but will not match the contract’s figure to the dollar, especially for early termination. When real money is on the line, ask the lessor for a formal payoff quote and compare it with the calculator’s number.
What competing calculators miss
Typical adjusted-balance tools
- Implement one formula variant and present it as the only definition.
- Ignore additional charges, which are the most common surprise at payoff.
- Never connect the balance to market value, so equity stays invisible.
This calculator
- Shows both the standard and depreciation-adjusted variants side by side.
- Includes additional charges and validates every input.
- Computes your equity position against market value with a clear verdict.
Frequently asked questions
The remaining amount owed on a lease after accounting for payments made, plus additional charges and optionally adjusted for depreciation. It is the practical answer to “what do I still owe on this lease?”
The standard form is original lease balance minus payments made, plus additional charges. The depreciation-adjusted form reduces the remaining balance by the depreciation rate before adding charges.
Not exactly. The buyout price starts from the payoff (built on the adjusted balance) and adds taxes, purchase option fees, and dealer or lender fees. The balance is the core; the buyout is the all-in total.
Your adjusted lease balance exceeds the vehicle’s market value: negative equity. Buying out an underwater lease means paying more than the car is worth, so returning it is usually the cheaper exit.
Many contracts use an actuarial constant-yield formula that compounds the implicit interest rate monthly, especially for early termination. The calculator’s simplified figure is for planning; request a formal payoff quote for exact numbers.
Yes, every payment reduces the remaining balance. Enter your total payments made (not just scheduled ones) to reflect prepayments or lump sums.
Excess mileage and wear fees, late fees, unpaid amounts, disposition fees, and any penalties in the contract. These are added to the remaining balance in both formula variants.
Often yes. Positive equity means the car is worth more than the payoff, so buying and reselling (or trading with the equity as a down payment) captures value that walking away would abandon. Run the full buyout math with taxes and fees first.
