The cost of gap insurance typically ranges from $20 to $40 per month, though the exact amount can vary based on factors such as the insurer, the type of vehicle, and the individual’s driving history. Some insurance companies offer gap coverage as an add-on to existing auto policies, which can sometimes be more affordable than purchasing it separately. Additionally, the cost might differ depending on whether the policy is bought through a dealership or directly from an insurance provider. It’s important to compare options and consider both the monthly premium and the coverage limits to find the best fit for your needs and budget.
