Travel insurance explained: the complete beginner's guide

What travel insurance actually is

A travel insurance policy is a contract. You pay a one-off premium, and the insurer agrees to cover a defined list of losses during a defined period. Those last two words matter: it is not a promise to fix everything that goes wrong on a trip. It is a promise to pay for particular events, up to particular limits, under particular conditions.

That is why two people can buy "travel insurance" and own very different products. One may have a cheap medical policy that would pay a hospital in Bangkok but would not refund a single dollar if they had to cancel. Another may have a generous cancellation benefit and a medical limit too low for a serious accident in the United States.

Think of it as a bundle of separate promises. Once you can see those promises individually, comparing policies gets much easier.

The main parts of a policy

The US Centers for Disease Control and Prevention (CDC) divides travel cover into three broad types, which is a useful place to start. We've added the everyday extras that most comprehensive plans include.

Optional upgrades sit on top of these, such as cancel for any reason, pre-existing condition cover and adventure sports riders. For a fuller breakdown, read what travel insurance covers.

Why your cover at home is probably not enough

Many people assume they are already protected. Sometimes that's partly true, but the gaps tend to be big.

• In the United States, Medicare generally does not pay for care outside the country. The State Department also makes clear that the US government will not pay your medical bills abroad.
• In Canada, the federal government warns that provincial and territorial plans may cover nothing, or only a very small portion, of care abroad, and never up front.
• In the UK, the Global Health Insurance Card gives access to state healthcare in the EU and some other places. The UK government states plainly that it is not an alternative to travel insurance, because it won't pay for things like repatriation or private care.
• In Australia, reciprocal healthcare agreements with a small list of countries can help with some urgent treatment, but they do not pay for a medical evacuation home.

If your home country isn't on that list, the same questions apply: does my cover work where I'm going, who pays up front, and who pays to get me home? Our home country guides go through this in more detail.

Is travel insurance ever legally required?

Most countries don't ask for it, but the number that do has been growing. The clearest example is the Schengen Area: under the EU Visa Code, applicants for a short-stay visa must hold medical cover of at least €30,000, valid across all member states for the whole stay. Georgia introduced a requirement for foreign visitors on January 1, 2026, and mainland Tanzania followed on October 1, 2026, with its own government-backed policy.

These rules move quickly and lists online often contradict each other. We keep a destination requirement tracker with the date of our last check, and our guide to countries that require travel insurance explains how to read the rules.

How much to budget

In the US market, Squaremouth reports that comprehensive plans typically cost 4% to 10% of prepaid, non-refundable trip costs. On a $5,000 vacation, that's a planning range of about $200 to $500. Medical-only plans can cost much less because they don't refund your trip.

Outside the US, you may find prices are based less on trip cost and more on your age, destination and how long you're away. Try our cost estimator for a benchmark, then read how much travel insurance costs to see what pushes the number up or down.

How to buy it well, in five steps

1. Work out what you would actually lose. Add up your prepaid, non-refundable costs. If it's close to nothing, you may not need much cancellation cover.
2. Check what you already have. Look at your health plan, your employer benefits and any credit card cover. Ask what they pay abroad, not just whether they exist.
3. Check your destination. If there's a visa or entry rule, your policy has to meet that rule's wording, not just your preferences.
4. Declare your health honestly. Undeclared conditions are a classic reason for a refused claim.
5. Read the exclusions before paying. Do this especially for activities you plan to do, such as scooter riding, scuba diving or skiing.

Timing matters too. Buying soon after your first booking gives you the longest protection against cancellation and can unlock extra benefits. See when to buy travel insurance.

What travel insurance won't do

It helps to go in with realistic expectations. Standard policies generally won't pay because you changed your mind, because a problem you already knew about got worse, or because of a loss you can't document. Many also limit or exclude claims connected with alcohol or drugs, unlicensed driving, and travel to places your government advises against visiting.

A useful test: before you buy, imagine your three most likely problems on this particular trip. Then find the page in the policy that addresses each one. If you can't find them, you're not ready to buy yet.

Our guide to common travel insurance exclusions walks through the clauses that catch people out most often.

If you only have five minutes

Pick a policy with solid emergency medical and evacuation limits, make sure cancellation cover matches your non-refundable costs, and declare your medical history. Then save the policy number and the 24-hour assistance line on your phone and share them with someone at home. In a real emergency, that phone number often matters more than anything else in the document.
