01
Tool inputs
A useful buyout calculator takes the residual value from your lease contract, an estimated current market value for the vehicle, any purchase-option fee, and applicable California sales tax. The residual is the agreed buyout amount in most lease contracts. California sales tax generally applies to the buyout transaction at the time of purchase, calculated on the buyout price.
02
Outputs and what they mean
The headline output is the cash cost to buy the vehicle today: residual plus any purchase-option fee plus applicable California sales tax. The decision-relevant output is the equity gap: estimated current market value minus the cash cost. Positive equity means buying out lets you capture value above the buyout amount; you can keep the vehicle or sell it. Negative equity means the buyout costs more than the vehicle is worth; returning the vehicle is usually the cheaper answer. A break-even output appears when the gap is small and the decision turns on softer factors (sentiment, the cost of switching cars, current rates if financing the buyout).
03
Assumptions baked in
Calculator outputs assume: the residual on your contract is current, the purchase-option fee is correctly captured, the market value estimate is reasonably accurate, and applicable California sales tax is calculated on the buyout price. Real situations break those assumptions in three common ways. First, market value is estimated; a single dealer offer is not the market. Use at least one reputable used-vehicle pricing data source. Second, the lender's buyout quote sometimes carries fees beyond the contract residual; pull the actual buyout quote rather than estimating from the contract. Third, financing the buyout introduces a new APR and total interest cost that the calculator does not capture in cash-cost output.
04
Decision table after the number
Use the table to convert calculator output into action. Equity meaningfully positive AND you want to keep the vehicle: buy out the lease, refinance the buyout if needed for cash flow. Equity meaningfully positive AND you do not want to keep the vehicle: buy out and sell privately or to a third-party dealer (the difference is yours). Equity roughly zero: return the vehicle and skip the transaction friction unless you have a strong reason to keep this specific vehicle. Equity meaningfully negative: return the vehicle; do not buy out a vehicle worth less than the buyout cost. The table fails when shoppers fixate on the calculator output without checking market value with a real source.
05
What this tool cannot know
The calculator cannot know your lender's actual buyout quote (request it directly), the real current market value (use a reputable pricing source), the rate you would qualify for if financing the buyout (soft-pull pre-qualify), or the cost of the alternative (returning the vehicle and choosing the next path). Use the calculator output as one input in the decision, not the decision itself.
06
Next steps
Pull your lease contract for the residual, fee, and purchase-option language. Request the actual buyout quote from your lender. Check at least one reputable used-vehicle pricing source for current market value. If financing the buyout, pre-approval from a bank or credit union shows you a rate range without committing to a single lender. 021 Auto Leasing routes shoppers to lender partners and is not the lender of record.

FAQ
Common Questions
How is a lease buyout calculated?
Residual value plus any purchase-option fee plus applicable California sales tax equals the cash cost. Compare that against the vehicle's market value to see whether equity exists.
Should I buy out my lease?
It depends on equity and your plans for the vehicle. A buyout makes sense when market value is meaningfully above the buyout amount or when keeping the vehicle is more useful than starting over.
Can I finance a lease buyout?
Yes. Lease buyout financing creates a new auto loan secured by the vehicle. Pre-approval from a bank or credit union shows you a rate range before committing.
What does the calculator not include?
Your lender's actual buyout quote (which can carry fees beyond the contract residual), the real current market value, financing rate if you finance the buyout, and the cost of the alternative (returning the vehicle and choosing the next path).
