How each state calculates the usage offset
All three states divide by 120,000 miles, but each counts different miles. That one difference drives the size of your deduction.
| State | Miles counted | Formula | Source |
|---|---|---|---|
| California | Miles driven before the first repair visit for the defect | Price × miles ÷ 120,000 | Civ. Code § 1793.2(d)(2)(C) |
| Texas | Miles before the first report at 100%, miles after it at 50% | (Price × miles before ÷ 120,000) + (50% × price × miles after ÷ 120,000) | 43 TAC § 224.260 |
| Florida | All miles up to the settlement or hearing | Price × miles ÷ 120,000 (motor homes: 60,000) | Fla. Stat. § 681.102(19) |
One car, three states, three different refunds
To see how much it matters, here is one car run through all three formulas.
| State | Offset | Price minus offset |
|---|---|---|
| California | $2,135.00 | $39,865.00 |
| Texas | $5,792.50 | $36,207.50 |
| Florida | $9,450.00 | $32,550.00 |
How the numbers work: in California, $42,000 × 6,100 ÷ 120,000 = $2,135. In Texas, the 6,100 miles before the first report cost $2,135, and the 20,900 miles after it cost half of $7,315, or $3,657.50. In Florida, all 27,000 miles count: $42,000 × 27,000 ÷ 120,000 = $9,450. Taxes, fees and incidental costs are then added under each state’s rules.
Which price is used to calculate the offset?
The offset is a share of the price, so which price is used matters too.
- California: the price paid or payable, including transportation and manufacturer-installed options (CACI No. 3241).
- Texas: the purchase price; leases use the lessor’s price and a separate TxDMV lease worksheet.
- Florida: the purchase price; leases return your lessee cost and pay the rest to the lessor.
Which miles and costs Florida leaves out of the offset
Florida’s Attorney General publishes a remedy calculation guideline that answers questions most offset guides skip:
- Price used: the base selling price on the purchase invoice, excluding taxes, government fees and dealer fees. For a lease, it is the agreed-upon value in the lease, reduced by any manufacturer rebate.
- Miles counted: only miles attributable to you. Subtract the mileage at delivery and other non-consumer miles, such as test drives by the service agent during repairs, manufacturer inspections and arbitration hearings.
- Cut-off date: the settlement date or the arbitration hearing, whichever comes first.
- Replacement awards: you pay the offset to the manufacturer to receive the replacement vehicle.
| Vehicle | Base price | Your miles | Offset |
|---|---|---|---|
| Car | $24,000 | 20,000 | $4,000.00 |
| Recreation vehicle (60,000-mile divisor) | $50,000 | 10,000 | $8,333.33 |
Common disputes over the mileage offset
Most arguments about the offset come down to a few points. Check each one against your own records.
- The first-repair mileage. In California and Texas the offset turns on when the defect was first reported. Compare the manufacturer’s figure with your earliest repair order.
- Delivery miles. Miles on the odometer when you took delivery are not your use.
- Test-drive miles. Florida excludes miles driven by technicians, inspectors and arbitrators.
- The price figure. Florida uses the base price without taxes and fees; California uses the price paid or payable, including transportation and factory options.
How the offset grows the longer you drive
Because each state counts different miles, waiting affects your refund differently. The table below uses one $40,000 car with the first repair at 3,000 miles:
| Miles at settlement or hearing | California | Texas | Florida |
|---|---|---|---|
| 15,000 | $1,000 | $3,000 | $5,000 |
| 30,000 | $1,000 | $5,500 | $10,000 |
California’s offset stops growing after the first repair visit. In Texas, each mile after the first report costs half as much as earlier miles. In Florida, every mile you drive up to the settlement or hearing counts in full, so filing promptly matters most there.
How to keep your usage offset low
You can keep the offset lower with a few simple habits from the first sign of trouble.
- Report the defect early. In California and Texas, miles before the first report count most.
- Get a repair order on the first visit, so the first-report mileage is on record.
- Check the manufacturer’s math. A later “first repair” date raises the offset; compare it with your own repair orders.
- File promptly. In Texas and Florida, miles after the first report or up to the hearing also count.

Frequently asked questions
What is the usage offset in lemon law?
A deduction from your refund for the use you got from the vehicle, calculated from the miles driven and the price, based on a 120,000-mile vehicle life in Texas, California and Florida.
How is the lemon law mileage offset calculated?
California: price × miles before the first repair ÷ 120,000. Florida: price × miles to the hearing ÷ 120,000. Texas: miles before the first report count fully and later miles count at 50%.
How do you calculate a lemon law buyback in California?
Start with the price paid or payable, add finance charges paid, sales tax, license and registration fees and incidental damages, then subtract the offset: price × miles before the first repair visit ÷ 120,000.
Is there a mileage limit for a lemon law refund?
The offset has no cap, but the window does: 24,000 miles in Texas and 18,000 for California’s presumption. Florida has no mileage limit on its 24-month rights period.
How do you calculate a lemon law refund?
Start with what your state counts as the price, subtract the usage offset (price × your miles ÷ the state divisor, usually 120,000), then add the taxes, fees and incidental costs your state includes. Our buyback calculator applies each verified state’s rules.
Is the lemon law mileage offset negotiable?
In a settlement, yes. Florida’s Attorney General notes that the consumer and manufacturer can agree before a hearing to a remedy that is more or less than the guideline amount. In a decision, the state formula applies.
Do I pay the offset if I take a replacement instead of a refund?
Yes, in Florida: the Attorney General’s guideline says that for a replacement award, you pay the offset to the manufacturer to receive the replacement vehicle. Other states set their own rules.
