How it works

What the calculator is doing

Choose whether the premium is entered as a monthly amount or an annual amount.

Enter the premium and the number of vehicles you want included in the budget.

The calculator shows the combined monthly and yearly insurance cost for planning.

Understanding your result

The combined cost matters because insurance is often evaluated one vehicle at a time even though the budget usually absorbs it at the household level. Seeing the monthly and yearly total together makes the cost easier to compare with payments, fuel, and maintenance.
