Car insurance premiums are billed either annually or monthly. Insurers calculate a base annual premium based on your driver profile, vehicle, coverage selections and location, then offer two billing paths. You can pay the full amount once or divide it across 12 monthly installments.
Most insurers add a per-installment fee to monthly plans because processing 12 payments costs more than processing one. GEICO charges around $5 per month, while Allstate and Farmers charge $5 to $10 per month. On a $1,200 annual premium, $5 monthly fees add $60 per year, bringing the total to $1,260 for the same coverage.
Annual policies bill the full premium at once with no added fees. Some insurers also reward the choice with a pay-in-full discount of 5% to 9%, which reduces the base premium before you even pay. GEICO and Progressive both advertise pay-in-full discounts, and State Farm and Nationwide make them available in select states.
