"Annual mileage" is the number of miles you are likely to drive in a year. Insurance companies understand that you cannot perfectly predict the number of miles you will drive in a year, so they will accept an estimation. If your circumstances change and you are likely to drive more than you anticipated, get in touch with us, and we can adjust your number.
Insurance companies use your annual mileage as one of many factors to assess your insurance premium. If you drive significantly more than the average person, you may have a higher premium. Conversely, if you drive less often you may be eligible for a lower rate.
To estimate your annual mileage, take the number of miles you drive in a normal month and multiply it by 12. When estimating, be sure to consider both your regular driving habits like commuting, as well as longer trips like vacations by car.
