1. Vehicle data: To start using the MTPL calculator, you must first enter information about the vehicle - its make, model, year of manufacture and registration number. This allows the calculator to identify the type of vehicle and try out its risk factors.

2. Driver information: The second step is to enter driver data. Information about all persons who will be authorized to drive this vehicle must be provided here. It is important to record their dates of birth and length of driving experience, which are essential criteria for calculating the insurance premium.

3. Insurance history: In some MTPL calculators, it may also be necessary to enter information about the driver's insurance history, for example, about paid MTPL or CASCO premiums in the past or about road traffic accidents that have occurred.

4. Validity period of the policy: Customers should specify the desired term of the insurance policy in the MTPL calculators. It is usually possible to choose between one year or a shorter period such as six months.

5. Choice of additional options: Each insurer offers a range of additional options. Passenger insurance, roadside assistance, legal assistance, etc. may be available. When choosing these additional options, they must be taken into account in the final price of the policy.

6. Comparison of offers: Once all the necessary data have been entered, MTPL calculator will generate multiple insurance quotes from different insurers. The user has the opportunity to compare prices, coverage and other policy conditions in order to choose the most suitable option.

7. Purchase: Once the best MTPL offer is selected, the user can proceed with the online purchase process. This usually involves paying for the policy (via internet banking, credit card, etc.) and receiving the electronic policy in your e-mail.

When using the MTPL calculator, it is important to fill in all the information carefully, as incorrect information can lead to an incorrect calculation of insurance costs and problems in the event that insurance costs are required to be covered after a traffic accident. Therefore, time and attention in the data entry process is very important.
