A foreign quote that is half the US price does not mean the trip saves half. The break-even question is narrower and more useful: given what this care would really cost you at home, and what the trip itself will cost, what is the highest foreign quote that still leaves you ahead? This page gives you the calculator, the formula behind it, and the inputs people most often get wrong.
The formula behind the calculator
The calculator does one subtraction:
Net difference = Home cost − (Foreign quote + Flights and transport + Lodging and companion + Follow-up and reserve)
Rearranged, it gives the number most people actually want:
Break-even foreign quote = Home cost − (Flights and transport + Lodging and companion + Follow-up and reserve)
If a clinic quotes more than that figure, the trip costs more than staying home. If it quotes much less, you have a margin. That margin, not the headline discount, is what absorbs a delay, an extra night or an unplanned visit. Each input has a common mistake, covered below.
Input 1: the home cost has to be what you would really pay
The most common error is entering the wrong home number. It should be your realistic out-of-pocket cost, not the largest figure a hospital can print.
- If you are insured: use your remaining deductible plus coinsurance for the whole episode, up to your out-of-pocket maximum. If you have already met much of your deductible this year, the home option may be far cheaper than it looks. See cash price vs insurance out-of-pocket and the deductible trap.
- If you are uninsured or paying cash: ask each US provider for a Good Faith Estimate. When a service is scheduled at least 10 business days ahead, or you ask for cost information, the estimate is due within 3 business days. When it is scheduled 3 to 9 business days ahead, it is due within 1 business day (CMS, 2021). Add up every provider's estimate.
- Include home costs you would have either way, such as pre-op tests your doctor orders regardless, only if they would be repeated abroad. Otherwise leave them out of both sides.
Input 2: the foreign quote has to be written and complete
Use a written quote for your case, not an advertised starting price. The CDC Yellow Book (2026 edition) cautions that follow-up beyond the base price can carry large additional fees at some overseas facilities, so confirm what the quote covers. If a line is unanswered, carry it as an unknown and price it in the reserve. Convert the quote at the rate your payment channel will actually give you, not the reference rate.
Input 3: flights and local transport
Price round trips for you and a companion. Use fares you could rebook, or include the change fee, because recovery can move your return date. Add airport transfers, rides to appointments and anything not in the package.
Input 4: lodging is set by the recovery rule, not the procedure
Lodging is where break-even calculations most often go wrong, because people budget the nights in the clinic's brochure. The CDC Yellow Book gives two planning rules:
- Don't fly for 10 days after chest or abdominal surgery.
- Following ASPS advice, wait 7 to 10 days to fly after cosmetic procedures to the face, eyelids or nose, or after laser treatment.
Start from those rules, add your surgeon's own instructions and any nights before surgery, then multiply by your nightly rate. Include a companion's room and meals if they need their own.
Input 5: follow-up and a reserve you can actually spend
This input covers two things. The first is planned follow-up: post-op visits abroad that aren't in the package, plus any care you will need at home afterward. Ask your home doctor before you go whether they will see you and what it will cost. The second is a reserve for the realistic bad week: an extra hospital night, extra lodging, a changed flight and local tests. CDC notes that complications can compound the original price.
The contingency reserve calculator helps size it. Payment matters too. The State Department's Colombia page (2025) points out that payment before admission may be required and that card payments are not always possible. The reserve has to be money you can reach quickly in the destination, not just a number on paper.
Costs the five boxes leave out, and when to add them
The calculator has five inputs so that it stays usable. Some real costs don't fit neatly into any of them, and you should add them to the closest box if they apply to you:
- Lost income. If a longer trip means unpaid leave, or using vacation days you would otherwise have kept, that is a cost the home option may not have. Put it in the reserve box.
- Travel insurance. A travel-medical or evacuation policy is part of the trip's cost. Add the premium to flights and transport.
- Home responsibilities. Childcare, pet care or a house-sitter for the extra nights abroad belong in lodging and companion.
- A second trip. If the care plan includes a staged procedure or a check-up that must happen at the same clinic, count the second set of flights and nights in full.
Do the same for the home side: if the US option means travel to a distant specialist, add it there too, so both sides are treated the same way.
US tax rules can move the break-even
For US taxpayers who itemize, some trip costs may count as medical expenses. IRS Publication 502 (2025) sets out the main rules:
- Only medical expenses above 7.5% of adjusted gross income are deductible.
- Lodging away from home can count, up to $50 per night per person, if the trip is primarily for and essential to medical care from a doctor in a licensed hospital or equivalent facility, with no significant vacation element. A companion can be included.
- Meals while traveling generally do not count.
- The standard medical mileage rate for 2025 is 21 cents a mile, plus parking and tolls.
- Cosmetic surgery generally does not qualify. Prescription drugs brought back from another country generally cannot be included either.
If your home option would also be deductible, the tax effect may roughly cancel out. Treat it as a refinement, and confirm it with a tax professional before you count on it.
A worked illustration
Hypothetical numbers for illustration only. These are not prices for any procedure or country.
- Home cost: $18,000.
- Flights and transport: $1,400.
- Lodging and companion: 14 nights at $110, which is $1,540.
- Follow-up and reserve: $2,500.
The break-even foreign quote is $18,000 − $5,440 = $12,560. A $9,000 quote leaves a net difference of $3,560, about 20% of the home cost. That margin is smaller than the 50% discount the headline numbers suggest.
Now stress-test it. Add five unplanned nights and a $400 flight change, and the margin falls by about $950. If the margin survives that kind of test, the decision rests on clinical grounds, which is where it belongs. If it doesn't, the trip only pays when everything goes to plan. See when flying doesn't pay for procedures where that is common.
How to read your result
- Negative net difference: the trip costs more than home care at these inputs. Recheck the home number before going further, especially for insured patients.
- Small positive margin: the trip works only if nothing changes. Get firmer quotes, or a firmer home price, before booking.
- Comfortable margin after a stress test: price is no longer the deciding factor. Spend your effort on verifying the surgeon, the facility and the follow-up plan.
Frequently asked questions
What does the break-even foreign quote mean?
It is the highest clinical quote abroad at which the whole trip still costs no more than your realistic home option, once travel, lodging, follow-up and your reserve are added. A quote above it loses money, and one just below it leaves very little margin.
What should I enter as the home option if I have insurance?
Your expected out-of-pocket cost for the episode, which means the remaining deductible plus coinsurance, up to your plan's out-of-pocket maximum. Do not enter the hospital's list price, because you would not pay it.
How many nights of lodging should I budget?
Budget by the recovery rule, not the procedure. CDC planning guidance says 10 days before flying after chest or abdominal surgery, and 7 to 10 days after facial cosmetic work, following ASPS. Add nights before surgery and your surgeon's own instructions.
Can travel costs for surgery abroad be tax-deductible?
Possibly, if you itemize. IRS Publication 502 (2025) allows qualifying medical expenses above 7.5% of AGI, and lodging up to $50 per night per person when the trip is primarily for medical care. Meals and cosmetic surgery generally do not qualify. Ask a tax professional.
Is this calculator a price estimate?
No. It only organizes numbers you enter. Prices must come from written quotes, and treatment decisions belong with licensed clinicians who have evaluated you.
Have a real quote you want made comparable?
Send the basics: procedure, country/city if relevant, timing and what you are comparing. This goes to the same medical lead pipeline used across the network.
