Probably the biggest factors when calculating travel insurance premiums is the length of the cover required. If you are taking a two-week vacation, there is a much lower risk than if you are making a yearlong voyage around the world. That said, there are many annual travel insurance policies that cover all the trips you make in a single year and if you make more than a couple of separate trips, annual protection may work out cheaper. Often family protection policies are not too much more expensive than a single persons policy so if you get the whole family insured together you are also likely to save.
Another big factor is where you are travelling. While some countries represent more health risks, as they are more dangerous, it is also a fact that poorer countries often have far lower medical costs so insurance tends to be highest for travellers in North America and Europe, with the US specifically recognised as having high health care costs. If you plan special high-risk activities such as skiing or mountain climbing you will either need separate insurance for this occasion, or to have the activity specifically added to your policy, as there is a good chance it will be excluded.
Insurance premiums are calculated according to several risk factors. These are the factors identified by the insurance company as most likely to have an impact on the insured against risk occurring. Insurance is a significant cost associated with the item insured and should not be rushed into. It is always a good idea to shop around for the best price available. Insurance premiums will vary considerably from insurer to insurer so do your homework.
Look up the various insurance companies you are interested in and ask them for a quote. They can usually give you a rough estimate fairly quickly and even more exact quotes should also be possible if you provide more details and wait. You should also look up insurers online and get instant quotes from their website. This is a very fast and effective way of shopping around. You will get a good idea of what prices to expect. You can also experiment with the quotation websites to see what effect it makes to your premium price if you select different options. With all insurance policies you will have a number of options that affect the price of the policy. Therefore you should think about these options and if there are risks that you do not wish to cover then let the insurer know as your premium should become cheaper.
You should also try to make sure you do not double insure. It is a principle of insurance that you cannot benefit from the insured events occurrence. So you cannot get paid twice even if you have two insurance policies. So if a risk is already covered by one policy, again let your insurer know so they can remove it from their calculation.
