Understanding Your Lease Mileage
When you lease a vehicle, one of the most crucial factors to consider is the mileage allowance.
Lease agreements typically come with a set number of miles you can drive per year. Exceeding this
limit results in overage charges, which can significantly increase the cost of your lease.
This Lease Mileage Calculator helps you estimate your total mileage allowance over the lease term
and the potential cost if you go over your allocated limit.
How the Calculator Works
The calculator uses a simple formula to determine your total mileage allowance and potential overage cost:
- Total Mileage Allowance: This is calculated by multiplying your Projected Annual Mileage by the total number of months in the lease term, divided by 12 months.
- Mileage Overage Calculation: If your Projected Annual Mileage is higher than the Allowed Mileage per Mile (which represents the annual allowance from your lease contract), the difference is multiplied by the number of years in the lease term to find the total overage miles.
- Estimated Overage Cost: The total overage miles are then multiplied by the Overage Charge per Mile specified in your lease agreement.
Key Terms Explained:
- Projected Annual Mileage: An estimate of how many miles you anticipate driving each year of the lease.
- Lease Term (Months): The total duration of your lease agreement in months (e.g., 24, 36, 48 months).
- Allowed Mileage per Mile: This field represents the annual mileage limit set by your lease contract (e.g., 10,000, 12,000, 15,000 miles per year).
- Overage Charge per Mile ($): The cost you will be charged for each mile driven beyond your lease's allowance. This is a critical number to know from your contract.
Why This Matters for Your Lease
Accurately estimating your driving habits is vital before signing a lease.
- Avoiding Penalties: If you consistently drive more than your allowance, the overage charges can add up to thousands of dollars by the end of your lease.
- Choosing the Right Lease: Understanding your mileage needs helps you select a lease contract with an appropriate mileage cap, potentially saving you money. Some leases offer higher mileage allowances for a slightly higher monthly payment.
- Budgeting: This calculator allows for better financial planning by highlighting potential extra costs.
If you find you are consistently exceeding your projected mileage, it might be worth considering a lease with a higher annual mileage allowance or exploring other vehicle acquisition options.
