Frequently Asked Questions
What is an excess mileage charge?
An excess mileage charge is a fee applied when a leased vehicle exceeds its contracted annual mileage allowance. Charges are calculated at a set rate per mile (pence per mile) for every mile over the allowance, applied at lease return.
How is excess mileage calculated?
Excess mileage is the difference between actual miles driven and the contracted mileage allowance. The charge is calculated as: (Actual Miles − Contract Allowance) × Pence Per Mile rate. This calculator projects that charge based on current trajectory rather than waiting until lease end.
What is a typical excess mileage charge rate?
Rates vary by vehicle, funder, and contract but typically range from 3p to 15p per mile for cars and light commercial vehicles. Premium and specialist vehicles may attract higher rates. Your lease agreement will specify the exact rate.
Can I avoid excess mileage charges?
Yes — the key is early identification. By monitoring mileage trajectory against contract allowance throughout the lease term, you can take action: redistribute mileage across the fleet, negotiate a contract amendment, extend the lease, or swap the vehicle early.
How often should I check fleet mileage against contract?
At minimum quarterly. Best practice is continuous monitoring using telematics data. This calculator is designed for periodic reviews; for real-time monitoring, see the Olaris mileage tracking feature.
